Python has no built-in function to find all occurrences of a substring. Furthermore, custom functions that use re.finditer or find are quite slow. Hence, whe...

There are many methods to classify time series using neural networks. This blog post will mainly focus on two-dimensional CNNs and how 1D series can be repre...

In this post, I will implement a simple object detector in Keras based on the three YOLO papers [1][2][3]. The complete code can be obtained from here.

In this blog post, I will derive a closed-form expression for a simple feed-forward neural network.
