Visualize time series forecast results using a moving average in Python, plot actual and forecast lines with Plotly, and assess forecast accuracy with error calculations.
Explain mean absolute error and its normalized mean absolute percentage error, and distinguish it from mean absolute error percentage, while outlining code to compute and print results.
Implement double exponential smoothing to forecast demand, incorporating trend with alpha and beta, initializing level and trend, and optimize parameters in Python while comparing to smoothing using mae and rmse.
Understanding and predicting the demand is one of the key challenge in Supply chain planning. Having better forecasting meaning better supply planning and optimized business operations with good customer service, therefore learn to build better forecast is a key skill to master in Supply chain management. Demand forecasting sounds simple but it will get complex when we have thousands of SKUs and each with its own demand pattern such as seasonal, intermittent and lumpy.
In this course you will learn demand forecasting models from basic to more advanced. And implement each of the models in Python. You will gain practical knowledge with real life data with over 3000 skus and over 5 years of data and millions of transactions.
By the time you complete the course you would have learned how advanced demand forecasting engine works in expensive commercial software and you would build your own fully automated forecasting engine.
In this course you will not only learn to build forecasting models and predict demand but also learn to build a python tool which can automatically optimize and select the best forecasting model based on your data.
Last but not least, you will learn to visualize all the forecasted data and errors in an intutive way.
