Summary
After getting down to a practical level in the previous chapter, we stayed there and plowed on to review concepts such as stationarity and how to deal with such non-stationary time series. We learned about techniques we can use to explicitly handle non-stationary time series such as differencing, detrending, deseasonalizing, and so on. To put this all together, we saw an automatic way of transforming the target, learned how to use the implementation provided, and applied it to our dataset. Now that we have the necessary skills to effectively transform a time series into an ML dataset, in the next chapter, we will start applying a few ML models to the dataset using the features we’ve created.
