What is Machine Learning?
- Machine learning is a subset of Artificial Intelligence that enables computers to learn from data, identify patterns, and make decisions without explicit programming.
- Machine learning differs from traditional programming as it can handle tasks like recognizing images, which are too complex for rule-based programming.
- There are three types of machine learning: Supervised Learning, Unsupervised Learning, and Reinforcement Learning.
- Steps involved in a machine learning project include problem identification, data collection, data cleaning, model selection, training, evaluation, tuning, and deployment.

The Bias—Variance Dilemma: Why Imperfection is the Key to Better Models
- Bias is the difference between the model’s predicted and actual values, indicating systematic errors due to simplistic assumptions.
- High bias leads to underfitting, where the model does not capture the complexity of the data well and performs poorly on training and testing sets.
- Low bias signifies the model accurately fits the training data by capturing underlying patterns and relationships.
- Illustration: Trying to fit curve-shaped data points with a straight line leads to a simplistic model that misses most of the data points, showcasing the impact of bias-variance dilemma.
