We know that to compare floating point values we should use epsilon and not just compare bits. We may run into similar issues when comparing BigDecimal in Java: What is the output? Of course it is false, otherwise I wouldn’t write this post. This is because BigDecimal includes scale: So we should use this: and … Continue reading Comparing numbers is hard
This is the twelfth part of the Custom memory allocation series. For your convenience you can find other parts in the table of contents in Part 1 — Allocating object on a stack We already know how to allocate memory anywhere on the heap but if you think that it solves all problems with GC … Continue reading Custom memory allocation in C# Part 12 — Hiding objects from GC

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
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
