Study Notes

Introduction to Machine Learning

  • Machine Learning (ML) is the process of training software, called a model, to make predictions or generate content from data.

Learning Objectives

  • Understanding different types of machine learning
  • Understanding supervised machine learning concepts
  • Learning how ML approaches differ from traditional methods

What is Machine Learning?

  • ML involves training software to make predictions or create content based on data.

What is the Training Process of ML?

  • Step 1: Prepare the data
  • Step 2: Create a training data source
  • Step 3: Create an ML model
  • Step 4: Assess model predictive performance and set a threshold
  • Step 5: Use the model to generate predictions
  • Step 6: Clean up

Types of ML Systems

  • Supervised learning
  • Unsupervised learning
  • Reinforcement learning
  • Generative AI

Supervised Learning

  • Supervised learning models predict based on data with correct answers, identifying connections between data elements to produce correct answers.
  • Common use cases are regression and classification.

Regression and Classification

  • Regression models predict numerical values.
  • Classification models predict the likelihood of something belonging to a category.

Unsupervised Learning

  • Unsupervised learning models predict using data without correct answers.
  • The goal is to identify patterns in the data.
  • The model infers its own categorization rules.
  • Clustering is a common unsupervised learning technique where the model finds data points that group naturally.

Reinforcement Learning

  • Reinforcement learning models predict by receiving rewards or penalties based on actions taken within an environment.
  • A reinforcement learning system defines the best strategy to maximize rewards.

Generative AI

  • Generative AI creates content from user input.
  • Generative models can vary input and output types.
  • Initially, training generally uses an unsupervised approach to mimic the data. Further training may involve supervised or reinforcement learning.
  • The goal is to produce unique and creative outputs.
  • Generative AI models learn patterns from data to produce similar but new data. Examples include comedians imitating others, artists emulating styles, or cover bands copying specific music styles.
  • There are constantly evolving new use cases emerging, such as e-commerce product image enhancement by automatically removing backgrounds or improving low-resolution images.
