Python's ChainMap: Manage multiple contexts effectively
Posted on August 23, 2021, Level intermediate Resource Length long
Sometimes when you're working with several different dictionaries, you need to group and manage them as a single one. In other situations, you can have multiple dictionaries representing different scopes or contexts and need to handle them as a single dictionary that allows you to access the underlying data following a given order or priority. In those cases, you can take advantage of Python's ChainMap from the collections module. By Leodanis Pozo Ramos.

PyTorch – How to apply Backpropagation with Vectors and Tensors
Posted on April 19, 2021, Level advanced Resource Length long
In Machine learning, a backpropagation algorithm is used to compute the loss for a particular model. The most common starting point is to use the techniques of single-variable calculus and understand how backpropagation works. However, the real challenge is when the inputs are not scalars but of matrices or tensors. By Strahinja Stefanovic.
