Description
This course delves into the fundamental aspects of time series analysis and forecasting. This course has subsections on exploratory data analysis, decomposition of a time series into trend and seasonality components, neural prophet model, ARIMA, time series forecasting using supervised machine learning (tree-based model), fundamentals of conformal predictions and Lag-Llama model for zero shot learning to make forecast predictions. The first segment (section 2) covers the definition of time series, importing and reading time series data using SQL Alchemy and Pandas, converting from long-form to wide-form time series data, DarTS time series class and a basic example of exponential smoothing using DarTS.The second segment (section 3) explains the structure of time series - trend, seasonality components and change points, investigating scenarios related to trend, seasonality, auto-regressive effects and change points using the Neural Prophet Model to make forecast predictions with detailed references for further reading.The third segment (Section 4) delves into ARIMA model, analysis of stationarity effects using ADF test, Auto-Correlation and Partial Auto-Correlation function in Time Series and Akaike Information Criterion to select ARIMA model parameters for making forecast predictions.The fourth segment (Section 5) covers time series analysis and forecasting using supervised machine learning, creation of lagged features for a time series forecasting model and the use of Light Gradient Boosting Machine (Light GBM) for time series analysis and forecasting.The subsequent segment (Section 6) covers the fundamentals of conformal predictions in time series forecasting, defining exchangeability hypothesis, EnbPI algorithm as a conformal predictions framework together with random forest regressor and calculation of coverage score.The segment six (section 7) covers Lag-Llama which is an open source foundational model for time series forecasting.Each segment has a google colab notebook associated with it.
