Study Notes

Machine Learning

  • Types of Machine Learning:
    • Supervised Learning: input includes training samples and desired output; output is a rule that maps input to output
    • Unsupervised Learning: input is samples; output is underlying patterns in data
    • Reinforcement Learning: input is a sequence of states, actions, and delayed rewards; output is an action strategy

Definition of Machine Learning

  • A computer program is said to learn from experience if its performance at tasks improves with experience (Herbert Simon)
  • Machine learning is the field of study that gives computers the ability to learn without being explicitly programmed (Arthur Samuel)

Relationship between AI, Machine Learning, and Deep Learning

  • AI is a broader field that includes machine learning and deep learning
  • Machine learning is a subset of AI that involves giving computers the ability to learn without being explicitly programmed
  • Deep learning is a subset of machine learning that involves the use of neural networks

Applications of Machine Learning

  • Digit Recognition: a classic example of a task that requires machine learning; involves recognizing handwritten digits
  • Email Categorization: involves categorizing emails into different categories
  • Playing Go Game: involves using machine learning to play the game of Go
  • Identifying Covid-19 Clusters: involves using machine learning to identify clusters of Covid-19 patients
