What is Machine Learning?

Machine learning is a subfield of artificial intelligence (AI).  It focuses on the development of self-learning algorithms and models. These ML models enable a system or software application to learn. As a result, it assists in making predictions and decisions without being explicitly programmed.

It is concerned with developing systems, web, and mobile applications equipped with automated capability. This enables applications to automatically analyze, interpret complex data, and recognize patterns. Consequently, it empowers the app to make intelligent decisions or predictions based on the input provided.

The primary objective of machine learning is to enable applications to learn from experience or data and improve performance over time. For this, it identifies patterns and relationships in the data. And then, its algorithms generalize, and thus make predictions or take actions on new, or unseen data.

Popular examples of machine learning apps:

• Google Assistant
• Snapchat
• Netflix
• Spotify
• Duolingo
• FaceApp
• Tinder

Why Is The Integration of Machine Learning in Android apps growing?
