A model of an artificial neuron is reviewed here. We know that any complex neural network is mostly composed of such artificial neurons. Here, we define a Python class for the neuron, and then use it in an example. The whole Python code is also available at the mentioned GitHub page.

In neural networks, Convolutional neural network (ConvNets or CNNs) is one of the main categories to do images recognition, images…

In the previous post, I described a simple way to think about matrices, namely as bipartite graphs. Today I'd like to share a different way to picture matrices—one which is used not only in mathematics, but also in physics and machine learning. Here's the basic idea. An $m\times n$ matrix $M$ with real entries represents a linear map from $\mathbb{R}^n\to\mathbb{R}^m$. Such a mapping can be pictured as a node with two edges. One edge represents the input space, the other edge represents the...
