Machine Learning Fundamentals

Machine Learning is a subset of artificial intelligence that enables systems to learn and improve from experience without being explicitly programmed. It involves algorithms that can extract patterns from data, allowing computers to make predictions or decisions.

The core idea behind Machine Learning is that machines can automatically learn and adapt through data analysis rather than following pre-programmed instructions.

DBSCAN: Density-based clustering

Principal Component Analysis (PCA) is a dimensionality reduction technique used to identify patterns in high-dimensional data. It transforms the original variables into a set of linearly uncorrelated variables called principal components.

Autoencoders are neural networks designed for feature learning, which can be used to reconstruct input data, effectively reducing its dimensionality.

Essential Machine Learning Concepts

Overfitting and Underfitting are two common issues in machine learning. Overfitting occurs when a model learns the noise or random fluctuations in the training data, leading to poor generalization on new data.

Underfitting happens when a model is too simple to capture the underlying structure of the data, resulting in poor performance both on the training and unseen data.
