I have been learning it for the past few weeks. I am amused by its ease of use and flexibility. In this blog post, I will go through a feed-forward neural network for tabular data that uses embeddings for categorical variables. If you want to understand the … Continue reading A Neural Network in PyTorch for Tabular Data with Categorical Embeddings

This makes us put more and more labeled data into our training set even if it does not belong to the same distribution of data we are actually interested in. For example, let's say we are building a cat classifier for door camera devices. We … Continue reading What to do when we have mismatched training and validation set?

The main aim of a time series analysis is to forecast future values of a variable using its past values. In this post, I will give you a detailed introduction to time series modelling. This would be the … Continue reading Understanding Time Series Modelling and Forecasting – Part 1
