What it does
tsai is a code library for working with time series, data recorded over time such as sensor readings or sales. It is built on PyTorch and fastai, two popular AI libraries.
It gathers many deep learning models designed for this kind of data and uses them for classification, regression (predicting a number), forecasting and filling in missing values.
It also lets you download many ready-made datasets for practice and includes tutorials.
Who it's for
Data scientists and researchers applying deep learning to time-based data.
