Forecasting has been one of the most powerful statistical methods employed the world over in various disciplines for detecting and analyzing trends and predicting future outcomes based on which timely and mitigating actions can be undertaken. To that end, several statistical methods and machine learning techniques have been harnessed depending upon the analysis desired and the availability of data. Historically speaking, most predictions thus arrived at have been short term and country‐specific in nature. In this work, multimodel machine learning technique is called EAMA for forecasting Covid‐19 related parameters in the long‐term both within India and on a global scale have been proposed. This proposed EAMA hybrid model is well‐suited to predictions based on past and present data. For this study, two datasets from the Ministry of Health & Family Welfare of India and Worldometers, respectively, have been exploited. Using these two datasets, long‐term data predictions for both India and the world have been outlined, and observed that predicted data being very similar to real‐time values. The experiment also conducted for statewise predictions of India and the countrywise predictions across the world and it has been included in the Appendix. The current focus on the analysis of environmental data for the prediction of future trends has made it a prime area of research worldwide. Based on the kind of data prediction and analytical techniques employed, the present as well as the future state of the data can be forecasted or predicted. Different techniques related to modeling, statistics, data mining, artificial intelligence (AI), and machine learning are used for the analysis of data from the past or present in order to forecast future trends. The various stages involved in such analysis and predictions include defining the task, collecting related data from various sources, analyzing the data, statistical analysis, data modeling, deployment of the collected data using multiple techniques, and finally, model monitoring. This kind of predictive analysis is frequently applied to various use case scenarios such as market sales prediction, customer requirement prediction, healthcare status prediction, collection analysis, fraud detection, and so forth. Among these, the analysis and prediction of healthcare data is considered to be an important area of application, especially for predicting the future state of proliferation of highly infectious diseases. In this context, the analysis of Covid-19 related data for predicting its proliferation and containment trends is of utmost importance for arresting this ongoing pandemic across the world. Its highly infectious nature and high mortality rates make every second a valuable one, as its infection and mortality rates continue to burgeon every single day. Countries across the world have adopted certain protocols to arrest the spread of the disease such as staying indoors, social distancing, hand washing, travel restrictions, lockdowns, and so forth. Some of these measures such as lockdowns are quite severe and affect normal human activities in unprecedented ways and have severe economic ramifications. For instance, the spate of lockdowns across the world recently has severely affected the GDP of the entire world, making robust forecasting of Covid-19 related parameters even more crucial. In order to meet this requirement, various denominations of analyses and predictions using information gathered from different sources such as daily updated websites, Kaggle, Orange, and Weka can be seen. As a result, various techniques and methodologies introduced by different researchers for forecasting the future effects of the Covid-19 pandemic can be seen competing with each other, with each having their unique strengths and weaknesses. Advanced AI techniques such as machine learning and deep learning have also being used to undertake such forecasting, with each technique having its own unique approach. In machine learning for instance, different approaches and techniques such as the regression model, the autoregressive model, the classification model, and so forth are used. The novelty of the work proposed and outlined in this article is that it considers an approach that combines nonlinear transmission and social-spatial and temporal transmission along with the monthwise prediction of future data. Most of the historical data-driven approaches have been linear methods, and do not consider the temporal or time-based transmission methods. As such, the contribution of the article can be outlined thus: 1. Building of a computational hybrid model with long term predictions for India, with statewise and datewise views. 2. Proposing the ensemble learning hybrid model that integrates different machine learning techniques and improves prediction accuracy. 3. Applying an autoregressive correlation model to predict the future behavior of Covid-19 data using past and seasonal data. 4. Use of the hybrid model to predict the future Covid-19 status of various countries, along with statewise, datewise data views predicted with the help of seasonal data such as heat, air quality, location, and other dynamically updated inputs. The organization of the article is as follows: Section 2 provides a brief background on related works and existing research pertaining to the field. Section 3 provides information about the dataset as well as the proposed supervised model. Section 4 provides a gist of the working methodology and Section 5 presents the forecast and prediction results and discussion and is followed by the conclusion as well as the future directions of the research. authors Al-qaness et al., 4 proposed a model for forecasting that used an adaptive neuro-fuzzy inference system (ANFIS). In this work an enhanced flower pollination algorithm and a salp swarm algorithm based method were proposed.

Pandey et al., 18 proposed a model for predictions in India using the SEIR model as well as the regression model with the help of John Hopkins University dataset. The proposed model had a lower error prediction rate and made predictions up to 2 weeks. Papastefanopoulos et al., 19 proposed six time series forecasting methods for the prediction of active case populations. The six time series methods were ARIMA, holt-winters additive model, TBAT, automatic forecasting procedure, DeepAR, and N-Beat. With the help of these six methods, deaths as well as recovered and confirmed cases were predicted and compared using data from various countries. The authors Pinter et al., 20 proposed a hybrid machine learning approach for pandemic predictions in which ANFIS and multilayered perceptron-imperialist competitive algorithm were proposed to predict the time series of infected individuals and mortality rate. The experimental results were predicted for 1-month. Rustam et al., 21 proposed different supervised machine learning algorithms for forecasting future Covid-19 trends. The LR, least absolute shrinkage and selection operator, support vector machine, and exponential smoothing were used for forecasting, but the predictions were made for only 5-10 days.

The authors of References 22,23 used Covid-19 data from the USA and Canada to predict and forecasting was done using deep learning with short term memory for only two successive days. Sengupta et al., 24 proposed machine learning and k-means clustering and hierarchical clustering methods that were used to forecast pandemic situations. In this method, Indian statewise and monthwise data were analyzed for predictions. The authors Sharma et al., 25 proposed a spatial-based transmission and forecasting with the help of the SEIQRD method.

The authors of Shinde et al. 28 presented different survey methods and it was demonstrated that forecasting methods using AI, machine learning, and deep learning methods. These methods provide the best resolutions for prediction. The authors of Zheng et al. 29 presented the state transition matrix model for datewise predictions with data predicted for short durations. The authors of Tuli et al. 30 proposed a wide-range Covid-19 data to be predicted across various countries with the help of machine learning. The authors of Shahid 31 proposed a deep learning model for long time predictions using LSTM, GRU, and Bi-LSTM. But this model did not include any dynamic parameters. The authors of Tuli et al. 32 proposed a Weibull based long short-term memory approach model for predictions across various countries. The authors of Kumar et al. 33 described the drone and body area network model to predict Covid-19 spread in the long term. But this work 34 similarly failed to include various dynamic and influential factors such as heat, climate change, air quality, and so forth. 35 The geographical based parameters are influenced the Covid-19. Especially the air pollution affects the lung inflammation. So, the location-based factors are considered for the prediction of the Covid-19. 36 Above reviewed methods predicted only short term future data and did not consider spatial transmission. And also long term predictions also were not proposed. The authors Sharma et al., 25 proposed monthwise and statewise data but did not consider spatial transmission. Clearly, advanced predictions are required to include monthwise and spatialwise predictions for the best data driven decision-making. In this article, it has been planned to incorporate monthwise predictions based on social-spatial transmissions and multiple changing parameters. 37 In addition, most of the previous works cited have failed to consider dynamically updating location-based parameters. In this proposed work additionally, dynamic parameters such as heat, air quality and other location-based factors have been duly considered for predictions. The recent denominating methods for Covid-19 prediction and limitation represented in Table 1 . A Covid-19 forecasting model has important ramifications since based on the direction of future predictions, different decisions will be triggered. This proposed prediction model is based on a hybrid model and is also called the ensemble learning, autoregressive, and moving regressive (EAMA) model. This EAMA model consists of an ensemble learning, an autoregression model, as well as a moving average model. The ensemble learning is used to combine multiple features and inputs, and considerably improves the accuracy of the predictions. The autoregressive model is used to make future predictions based on previous trends and past data measurements. The moving average model similarly forecasts data by using current and past Covid-19 data. The proposed hybrid model therefore consists of various steps that are involved in the forecasting of Covid-19 related trends. Steps involved in the proposed method: The diagram of the proposed architecture is shown in Figure 1 where the hybrid model based on the ensemble learning is demonstrated. The essence of the hybrid approach is the combination of the sequential and nonsequential data models used to predict the Covid-19 data scenarios. The EAMA model aims to incorporate features such as timing, moving patterns of patients, past data, and past behavior of the state and country data using ensemble learning. The ensemble learning examines the state and location-specific data. The location and timing features are incorporated in a weight matrix in a supervised learning model. The past inputs, past measurements, and the time-series based predictions, and so forth are saved in the weight matrix based on the locations. The future inputs and a training model are then used to yield the statewise predictions for a single country or across different countries. The EAMA model continuously incorporates new location and timing-based data and find the errors in these predictions. The errors are then rectified in subsequent predictive iterations. The machine learning method and the EAMA hybrid models yield different predictions in the datewise and locationwise views. The proposed model focuses on a hybrid statistical time series method to predict future data based on patterns, time, linear predictive models, and nonlinear input and output data. The main advantages of the proposed work are improved prediction rates over a longer time period and increased prediction accuracy. The governing Equation (1) of the proposed hybrid model is as given below: Z i (t) denotes the EAMA forecast model and Y i (t) denotes the current forecast data ensemble learning model. X i (t) denotes the observation of data on a time series at time t and location with various seasonal parameters. e i (t) is the data error in the model. The main advantages of the proposed hybrid model compared with previously existing works are predictions over a longer time period and increased accuracy. The materials, the combined supervised hybrid model, and the working procedures of the proposed hybrid method are presented in the upcoming sections. Dataset: The dataset used in this research work played a crucial role in the accurate prediction of Covid-19 cases. We have collected data mainly from two sources: 1. Ministry of Health & Family Welfare, Government of India: 38 Data pertaining to all the Covid-19 cases in India was taken from the website of the Ministry of Health and Family Welfare which is maintained by the Indian Government. 2. Worldometer: 39 Covid-19 data for the rest of the world was taken from the "Worldometer" website which is run by an international team of developers, researchers, and volunteers. This website is recognized by the American Library Association. The aforementioned datasets are updated regularly. Consequently, the nature of this data is highly dynamic. We took the latest data available at this point to plot all the graphs and to create various kinds of tables. For plotting the graphs, data up till the month of July 2020 was used. Furthermore, we predicted the Covid-19 cases for the next 3 months (until October 2020) using different machine learning methods for time-series forecasting. Duration of Data: 1. India: From 30 January 2020 to July 2020. 2. World: From 22 January 2020 to July 2020. The data is classified into three categories: We have incorporated the above three categories of data in our datasets. To calculate the "Active Cases," we added the total "Recovered Cases" and "Deaths" and then subtracted the resulting number from "Confirmed Cases." In addition, we have added two new columns in our dataset for India, namely; "Death rate per 100" and "Cure rate per 100." Different supervised machine learning models have been used to predict and analyze future data. Some of the models mainly used in this study are ensemble learning, autoregressive model, and moving average regressive model. Ensemble learning: Ensemble learning is a combination of multiple models such as experts or classifiers that are generated in order to solve a particular intelligence problem. The main usage of ensemble learning is to improve the prediction, classification, and to construct better approximations of functions that need to be learned. Using this method, the prediction performance is improved and unfavorable circumstances arising from the use of poor predictions are eliminated. This learning model is used for decision-making processes, incremental learning, and error correction. In this learning model, "boosting" is employed to increase the weightage for training data that is misclassified so that the existing weak classifier can be strengthened. Use of this boosting concept produces better accuracy. The boosting can be represented as Equation (1) and (2) . where D 1 denotes the base leaner or training model, L 1 denotes the weight assigned with the corrected classifier, and L 2 denotes the boosted classifier. D 2 denotes the second base learner. Using this boosted D 1 and D 2 , the best results are achieved with help of voting between these two base learners or averaging them. Autoregressive model: An autoregressive model predicts the data based on time and measurements taken from previous actions. The previous actions and the statistical correlation between the observations in the past are used to predict the data (in this case Covid-19 data) at future instances. 40 The governing equation of the autoregressive model is represented as Equation (4). P(t + 1) denotes the prediction value at time t + 1, C denotes constant location, T denotes various logged features, W(t − i) denotes weight, t denotes time. The rate at which Covid-19 spreads is changing every day. With seasonal changes, Covid-19 predictions fluctuate every day. Ensemble learning is used to train the model and update the effects of data automatically. Ensemble learning takes into account the seasonal changes and corresponding factors are used to boost the training model automatically. The parameters encapsulating seasonal changes such as heat, humidity and air quality are updated in every round of boosting. Based on the boosting, the quality of prediction is improved and incorrectly predicted data from previous iterations is also updated. Equations (2) and (3) are used for training and updates every day. Equation (5) is used to represent a fixed region and changing seasonal parameters represented in Equation (6). X i (t) denotes the observation of data on a time series at time t and region. ∑ (X) represents different regions and including X are constants. ∑ (CP) represents different changing parameters based on seasonal changes. Σ(CP) represents different parameters at the initial time, CH 1 (t) denotes heat, CH 2 (t) denotes humidity,CH 3 (t) denotes air quality, CH n (t) denotes upcoming parameters, CP n (t + 1) denotes next time continuous updating values. In Equation (4), ∑ (X) represents different locations and Σ(CP) represents the changing parameters with respect to region and time. These parameters are changing every day. The final prediction of Covid-19 spread per day is as shown in Equation (7). As mentioned in Equation (5), Σ(X) denote represents different locations with X as constants and Σ(CP) denote represents different dynamic parameters based on seasonal changes. The updated prediction represented in Equation (8) . P(t + 1) denote the prediction value of t + 1, w(t).f (t) denote predicted features data f (t) is the partial derivation with respect to weighted data w(t), f (t) denote various features of the seasonable change. Using Equation (4), the past trends in Covid-19 data can be extrapolated to predict future qualitative and quantitative behavior. Ensemble learning is an automated learning model and it supports different parameters and combines different parameters. The two main parameters that are used for training and testing are location and dynamic seasonal parameters. The (X) is considered as location and is essentially constant. The (CP) encodes dynamic parameters with each and every parameter being updated for every iteration of the computations. The initial data was employed as the training data, but later, all the parameters are automatically trained and updated. Moving average model: The moving average model is a common model for predicting data based on the linear dependence existing between the current and past values. The forecasting model is represented in Equation (9). where, y t denote the weighted moving average. t denote the error rate. 1 + ... + p denote the different time-series pattern. q denote moving average data. In the Algorithm 1 represented the various procedure and steps for prediction of the Covid-19. Initially the various input dataset sources are included to the training and testing of the model. Second part of the proposed work, included various parameters such as location and other features are incremented. The help of D1 and D2 simultaneously all the features are boosted continuously. Step 1: The collected Covid-19 sample data from February to July duration is used as training data. Step 2: Determine the best sample using the EAMA model based on current sample and training data. • Ensemble learning combines different inputs such as location, migration data, and past data, and is described in Section 3.2. • Autoregressive model measures the current and past data and based on this, the future data is predicted as explained in Section 3.2. • Moving average model, forecasts the future data using past and present values, and produces average values from multiple instances of data. Step 3: Train the model using the series of data generated and produce boosted classifiers with the help of D1 and D2 recursively. • The future data is correlated using Equation (3) and weight W(t − i) and time series t is updated continuously. • Obtain the weighted and fine grained solution using Equations (5)- (8) . The sample is validated, tested, and predictions are generated. Step 4: Final predictions are generated using moving average model (with the help of Equation (5)). Continuous prediction and testing are performed in different iterations. This section describes the achieved results and presents them in a diagrammatic way. For the implementation of the algorithm and the discussion of the results, two datasets are used, and these are described in detail in Section 3.1. The proposed EAMA hybrid model achieved significant predictive accuracy on three parameters, namely, the number of people affected, the number of recoveries, and mortality figures. The predicted results are shown in Figures 2 and 3 and are also fully tabulated in the appendix. The predictions pertaining to India and various countries from the months of July to October 2020 are shown in Figures 2 and 3 . The proposed hybrid model was predicted from January to July data. For implementation, different metrics such as Reproductive Number (R0), MAPE, RMSE, prediction error are employed. The R0 value is used to measure the closest value and to find the related values. Some of the R0 values that are used in the prediction are as follows: Italy (0.95), France (0.85), Germany (0.85), Spain (0.85), India (0.9-1.25), United states (0.9), United Kingdom (0.85). Among Indian states the maximum R value is more than 1 as seen in Kerala. These regressive base values are also used in the implementation of the model for the prediction of Covid-19 cases. Some other metrics used in the prediction are as shown Equations (10)- (13) . The output of the prediction results are based mainly on the twin parameters of affected and forecast data for the India and the world. For the implementation of the proposed EAMA model, we used 80% as training data, 10% for testing, and 10% for validating. The proportions of data used for training, testing, and validation produced the best results compared with other proportions of training, testing and validating data. The prediction anticipates a linear growth in the spread of Covid-19 cases. This predicted model is based on the location, past data for the number of people affected in the particular geographical area, the movement patterns of people, and so forth. The scope of the prediction is gradually expanded and corresponding real-world data is also gradually increased. The prediction of the corresponding parameters at an international level is shown in Figure 4 . In this prediction, the positive cases are decreasing in some periods, and again increasing in certain other periods. The overall cases in the world gradually increased and then gradually decreased. In the middle of August month, the positive cases spiked up suddenly due to the renewed migration of people. Table A1 shows the statewise prediction in the India and Table A2 shows daily forecasting data for the India as well as the world. The prediction values are seen to have increased gradually ( Figure 5 ). Figure 6 shows the prediction Covid-19 affected cases worldwide from July to October 2020. The worldwide positive cases, death cases, recovery cases and the confirmed cases are shown in Figure 4 . The confirmed cases and active cases are seen to be high again in the worldwide predictions. In this prediction, the recovery cases are seen to gradually decrease and death cases are also found to gradually increase because the number of affected people in advanced age groups are very high worldwide. Figure 5 shows the forecast predictions of various parameters in the India. For the India, the prediction of the following parameters are made, namely; cure rate per 100 people, death rate per 100 people, active cases, cured cases, confirmed cases, and so forth. Figure7, confirmed Covid-19 cases seem to be always very high when compared with other parameters. The exact values of the cured and affected numbers are mentioned in Appendix A1. The number of deaths in the India have been quite low but at the end of October, it is bound to have a huge jump due to climatic change, geographical changes, and the number of people affected. In the north India and the south India, cases increased due to the geographical and climate changes. Especially in the north India end of the October and starting of the November the huge number of cases are increased due winter starting. But in the south India, due to weather changes and reduction of migration of the people, cases are reduced. So, automatically the affecting people ratio is reduced in the south India. The active cases are gradually decreasing compared with the number of affected patients. In the India, the real prediction and the forecast are both very similar. Table A1 shows the data forecast statewise and as opposed to the previous methods, it shows highly accurate predictions. Similarly, Figure 7 shows the world-wide predictions and it uses four parameters, namely, confirmed cases, deaths, recoveries and active cases. The number of confirmed cases, active cases, and deaths are seen to gradually increase but the recovery rate exhibits a marked reduction. The daily international forecasting values and Indian forecasting values are shown in Table A2 and the countrywise forecasting values are shown in Table A3 . In this way, all the predictions are compared with the actual daily data and the results are also shown to be fairly close. Compared with the previous methods, the main advantages of this work are the high accuracy of the long-term predictions and their marked similarity with real-world data. The proposed hybrid model makes it possible to acquire novel features of the data because it predicts Covid-19 cases based on different scenarios such as location, past data, movement patterns of citizens, and so forth. The proposed hybrid supervised model EAMA employed a combination of ensemble learning techniques, autoregressive, and moving regressive models. Using this mixture of techniques helped to easily combine multiple features and inputs, predict future data using past data trends, and produce average aggregate results. The proposed model had 80%, 10%, and 10% of the overall data for training, testing, and validation, respectively. Therefore, the prediction performance was seen to be high, as was the validation accuracy. For implementation, two different datasets were used, the ministry of India dataset and the Worldometer dataset from the months of February to July 2020. Using this hybrid EAMA model, different parameters were predicted at an international and national level such as the number of affected cases, confirmed cases, and deaths. Especially in the India, the number of active cases and deaths were predicted at a statewise granularity. The main novelty of the proposed work lies in its long-term prediction accuracy, as opposed to other methods which work only for a short duration. Using these predictions, we can easily measure the future trajectory of Covid-19 cases and employ it in decision and policy making processes. The future work should incorporate different models such as recurrent neural networks and also use nonlinear methods for predictions tailored to specific geographical locales.
