Machine learning can be categorized into three main types: supervised learning, unsupervised learning, and reinforcement learning. Supervised learning uses labeled data to predict output values, examples include linear regression, decision trees, random forests, boosting trees, and neural networks. Unsupervised learning finds hidden patterns in unlabeled data, common techniques are clustering algorithms like K-means, Gaussian mixture models, and hierarchical clustering. Reinforcement learning is about an agent learning through trial-and-error interactions with an environment to maximize rewards, it has been used by Google to reduce energy consumption by 15%.

DefinitionsCDI Aljeer

��

This document defines technical terms related to 3D modeling and computer-aided design. It provides definitions for over 50 terms, including types of views (perspective, orthographic), basic shapes (cube, sphere, cylinder), geometric concepts (dimension, edge, face, polygon), modeling tools (extrude, fillet, scale), and visual properties (materials, texture). Understanding these terms is fundamental for working with and creating 3D models on the computer.
