In the very early days of computers (say the 1950s and 1960s), most guys who entered the new field of “computer science” came from a background in either mathematics or electrical engineering. There’s always been a strong connection between mathematics … Continue reading →

I wrote an article titled “Neural Network Momentum using Python” in the August 2017 issue of Visual Studio Magazine. See https://visualstudiomagazine.com/articles/2017/08/01/neural-network-momentum.aspx Momentum is a technique intended to speed up neural network training. Training a neural network is the process of … Continue reading →

A standard neural network classifier builds a model that predicts output values from input values. For example, the famous Iris Data has 150 items. Each item has four predictor variables (sepal length, sepal width, petal length, petal width) followed by … Continue reading →

I’ve been looking at time series regression recently. Just for fun I coded up an example using a raw Python (with the NumPy library for numerical functions) neural network. For my example I used a standard benchmark data set that … Continue reading →

I use several different programming languages. Whenever I switch between languages, there’s always an adjustment time in my head. For some reason, whenever I switch from C# to Python with NumPy, it always takes me about an hour to start … Continue reading →
