Introduction to Regularization to Reduce Overfitting of Deep Learning Neural Networks

#artificialintelligence

The objective of a neural network is to have a final model that performs well both on the data that we used to train it (e.g. the training dataset) and the new data on which the model will be used to make predictions. The central challenge in machine learning is that we must perform well on new, previously unseen inputs -- not just those on which our model was trained. The ability to perform well on previously unobserved inputs is called generalization.


A Guide to Generalization and Regularization in Machine Learning

#artificialintelligence

Generalization and Regularization are two often terms that have the most significant role when you aim to build a robust machine learning model. The one-term refers to the model behaviour and another term is responsible for enhancing the model performance. In a straightforward way, it can be said that regularization helps the machine learning models for better generalization. In this post, we will cover each aspect of these terms and try to understand how these are linked to each other. The major points to be discussed in this article are outlined below.



Avoid Overfitting with Regularization

Did you ever think why this happens? This article explains overfitting which is one of the reasons for poor predictions for unseen samples. Also, regularization technique based on regression is presented by simple steps to make it clear how to avoid overfitting. The focus of machine learning (ML) is to train an algorithm with training data in order create a model that is able to make the correct predictions for unseen data (test data). To create a classifier, for example, a human expert will start by collecting the data required to train the ML algorithm.
