Machine Learning Part 8 — Backpropagation in neural net in SQL

This is the eighth part of the ML series. For your convenience you can find other parts in the table of contents in Part 1 – Linear regression in MXNet Last time we saw forward propagation in neural net. Today we are going to extend the process to backpropagate the errors. Let’s begin. We need … Continue reading Machine Learning Part 8 — Backpropagation in neural net in SQL

Machine Learning Part 7 — Forward propagation in neural net in SQL

This is the seventh part of the ML series. For your convenience you can find other parts in the table of contents in Part 1 – Linear regression in MXNet Today we are going to create a neural net and calculate forward propagation using PostgreSQL. Let’s go. We start with definition of the network: we … Continue reading Machine Learning Part 7 — Forward propagation in neural net in SQL
