While COVID has taken a toll globally, its imperative damage in India has been serious because of a large population base. In this scenario, daily prediction of COVID cases can help concerned authorities better brace themselves of the upcoming effect. Since cases form a time series data, their prediction remains a challenge due to inherent order in data points, which is tough to capture in statistical regressions. In addition, number of cases depends on a numerous factor in practical life, and to arrive on an exhaustive list for the purpose of modelling poses another challenge. To tackle these problems, we present a study spanning January 2020-April 2020, outlining way of using LSTMs for predicting 1-3 days in advance the number of cases in India and present a comparative analysis over inclusion of different factors in the prediction and its effect on accuracies. We achieved a R2 score of over 0.9 for short periods spanning 1-5 days, but model fails to capture long term (over 15 days) trend. Similarly, adding cases from Top 5 states as input factors increased the accuracy significantly for lookback = 4 to 0.99.
