To fully understand the theory of how neural networks learn you have to have a close look at backward propagation. This tutorial provides that close look.

Following the previous tutorial in this series which examined the math underlying neural networks, this tutorial offers a closer look at the formal learning (or training) process necessary for neural networks to produce meaningful predictions.

More succinctly, the previous lesson taught about the general structure of artificial neural networks (ANNs) and how data flows through the model, and how each layer processes the data. You can find the previous lesson which includes coding examples in Python and lesson here.

Studying dense neural networks are an important step on the journey of learning data science. Dense neural networks are used in various domains to solve regression and classification problems.

While other more traditional and classic approaches can also solve regression and classification problems, we turn to neural networks, which can often pick up more complex predictive signals from the data. Also neural networks are also in more complex deep… Read the full blog for free on Medium.
