    Study Notes

    Machine Learning Overview

    • Machine learning involves training multiple instances of the same learning algorithm or combining multiple weak learners to form a strong learner.
    • There are three types of machine learning: Supervised Learning, Unsupervised Learning, and Reinforcement Learning.

    Supervised Learning

    • Supervised learning involves learning to predict target values from labeled data.
    • Examples of supervised learning include regression, object detection, and face detection.

    Unsupervised Learning

    • Unsupervised learning involves learning to find patterns or structures in unlabeled data.
    • Examples of unsupervised learning include clustering, outlier detection, and dimensionality reduction.

    Reinforcement Learning

    • Reinforcement learning involves a learning agent perceiving and interpreting its environment, taking actions, and learning through trial and error.
    • Examples of reinforcement learning include winning a game of chess and predicting the next video frame.

    Model Types

    • There are two types of machine learning models: Discriminative models and Generative models.
    • Discriminative models classify data, such as classifying an image as a dog or a cat.
    • Generative models produce new data, such as producing a realistic dog or cat image.

    Ensemble Learning

    • Ensemble learning involves combining multiple models to produce better results.
    • There are two types of ensemble learning: Bagging techniques and Boosting techniques.
    • Bagging techniques involve training multiple instances of the same learning algorithm.
    • Boosting techniques involve combining multiple weak learners to form a strong learner.

    Applications of Machine Learning

    • Applications of machine learning include object detection, hand writing recognition, and face detection.

    Learning Objectives

    • CO1: Understand, visualize, analyze, and preprocess data from a real-time source.
    • CO2: Apply appropriate algorithms to the data.
    • CO3: Analyze the results of the algorithm and convert to appropriate information.
    • CO4: Evaluate the performance of various algorithms and suggest the most relevant algorithm.
