When I was first learning PyTorch, I implemented a demo of the IMDB movie review sentiment analysis problem using an LSTM. I recently revisited that code to incorporate all the things I learned about PyTorch since that early example. My … Continue reading →

Sometimes it’s useful to assign fixed weight and bias values to a neural network. To do so requires a knowledge of how those values are stored. I wrote a short demo program to illustrate the technique. The demo creates a … Continue reading →

Sometimes library code is too helpful. In particular, I don’t like library code that uses default mechanisms. One example is PyTorch library weight and bias initialization. Consider this PyTorch neural network definition: import torch as T device = T.device(“cpu”) class … Continue reading →
