Machine Learning Algorithms

Deep learning has become very famous over the last few decades, thanks to hundreds of applications that are changing the way we interact with many electronic (and non-electronic) systems. Speech, text, and image recognition; autonomous vehicles; and intelligent bots (just to name a few) are common applications normally based on deep learning models that have outperformed any previous classical approach. However, to better understand what a deep architecture is, we need to step back and talk about standard artificial neural networks (ANNs).
An ANN or simply a neural network is a directed or recurrent computational structure that connects an input layer to an output one. Normally, all operations are differentiable, and the overall vectorial function can be easily written as follows:
The function transforms a vector into another one by applying the same operator element-wise. Therefore, we assume the following:
The adjective neural comes from...
