What is Machine Learning?
Machine learning is a part of artificial intelligence (AI). It helps computers learn from data and make decisions on their own. This field aims to make computers as smart as humans, by recognizing images, understanding language, or taking actions.
Understanding the Fundamentals
The basics of machine learning come from statistics and math. It started in the 1950s with Arthur Samuel’s work on checkers. By the 1960s, a “learning machine” called Cybertron was made to analyze sounds and speech.
Tom M. Mitchell defined machine learning in the 1970s. He said it’s about computers learning from experience. Today, it’s about using models to predict future outcomes.
The Role of Data in Machine Learning
Machine learning uses lots of data to find patterns and make predictions. Companies use it to forecast trends and improve operations. Cleaning and preparing data is key to training models.
But, there are challenges like overfitting and imbalanced data. These can affect how well models work. Making models easy to understand is also a big challenge.
