### The Number of Hidden Layers

There are really two decisions that must be made regarding the hidden layers: how many hidden layers to actually have in the neural network and how many neurons will be in each of these layers. We will first examine how to determine the number of hidden layers to use with the neural network. Problems that require two hidden layers are rarely encountered. However, neural networks with two hidden layers can represent functions with any kind of shape. There is currently no theoretical reason to use neural networks with any more than two hidden layers.

### A Beginners Guide to Artificial Neural Network using Tensor Flow & Keras

TensorBoard is a great interactive visualization tool that can be used to view the learning curves during training, compare learning curves across multiple runs, analyze training metrics and many more. This tool is installed automatically with TensorFlow. As stated earlier, there are no predefined rules on how many hidden layers or how many neurons are best suited for a problem space. We can use a RandomizedSearchCV or a GridSearchCV to hyper tune a few parameters.

### Neural Architecture Search -- Limitations and Extensions

For the past couple of years, researchers and companies have been trying to make deep learning more accessible to non-experts by providing access to pre-trained computer vision or machine translation models. Using a pre-trained model for another task is known as transfer learning, but it still requires sufficient expertise to fine-tune the model on another dataset. Fully automating this procedure allows even more users to benefit from the great progress that has been made in ML to date. This is called AutoML, and it can cover many parts of predictive modelling such as architecture search and hyperparameter optimization. In this post, I focus on the former, as there has been a recent explosion of methods that search for the "best" architecture for a given dataset.

### Introduction to ML

As many readers are no doubt aware, there's a type of computation that's brought new perspective to a wide swath of common and previously intractable problems, and unlike a more deterministic programmatic approach, this new approach to is based on learning. That's right, instead of a linear sequence of instructions these algorithms figure out what to do for themselves. There's probably not a single aspect of our modern world that isn't affected by or directly based on the new field of learning-based methods. But this isn't just any type of learning: Meat Learning, or ML for short, affects almost every essential experience in the modern world. Choosing what book to read next?

You want to carefully select these features and remove any that may contain patterns that won't generalize beyond the training set (and cause overfitting).
