Machine learning is a pivotal component in many AI applications, enhancing their accuracy and efficiency.
2.1. The Learning Process in ML
In machine learning, the system is trained using a dataset. The algorithm analyzes this data to identify patterns, relationships, and dependencies. Once the algorithm has learned from the data, it can then be used to make predictions or decisions on new, unseen data. The more data the algorithm is exposed to, the better it becomes at making accurate predictions.
2.2. Types of Machine Learning
There are several types of machine learning algorithms, each with its own strengths and weaknesses. The main types include:
