In this post I share how to create a dot pattern portrait effect using Python, inspired by the same effect achieved using Photoshop.
This post introduces a simple Python script that batch downloads and processes climate indices from the NOAA PSL webpage.
In this post we are going to work out a vectorized Mann-Kendall trend test implementation using numpy and scipy.
In this post we put together all the building blocks covered in previous posts to create a convolution neural network, using numpy, and test it on the MNIST hand-written digits classification task.
This post covers the derivations of back-propagation in a convolution layer, with numpy implementations.
This post covers the implementation of pooling layers in a convolutional neural network using numpy.
This post will share some knowledge of 2D and 3D convolutions in a convolution neural network (CNN), and 3 implementations all done using pure `numpy` and `scipy`.
This post will share some basic knowledge of an artificial neural network and how to create one from scratch using only numpy. We will build a classification network to classify hand-written digits from the MNIST dataset.
`Gplot` is a (thin) wrapper around `matplotlib`, `basemap` and `cartopy` for quick and easy creations of geographical plots.
In this post I share a simple hack to automatically format the contour labels in a suitable string format in a matplotlib contour plot.
