When standing up a model to use in the real world there is a long list of considerations to take into account, from checking the integrity of the training data to understanding the biases and assumptions in different modeling algorithms to selecting the best metrics for evaluating the model. All of these considerations (and many more) are vital steps to creating a quality model. For each step there are a vast number of solutions, all of which are better or worse depending on the data at hand. Having an intimate understanding of the data (specifically any biases in the training…


Time series forecasting has always been a bit of a pain for machine learning. Everyone always wants to know what the future holds, and they say data is the key to all the answers, so asking “can a model tell me what happens next?” is not an illogical question to ask. Unfortunately, that question is significantly more difficult to answer than “is this a picture of a cat or a dog?”. While computer vision is no joke, the difficulty in time series forecasting isn’t just a statistical or computational problem, but a human problem.

In all of machine learning there…
