Lecture 12: Machine Learning

Machine learning is a subset of AI that enables systems to learn from data. The three main paradigms are:

  • Supervised Learning — learns from labeled training data
  • Unsupervised Learning — discovers hidden patterns in unlabeled data
  • Reinforcement Learning — learns through trial-and-error with rewards
Supervised vs Unsupervised

The two most common paradigms differ fundamentally in how they use training data:

AspectSupervisedUnsupervised
LabelsRequires labeled dataWorks with unlabeled data

My bio textbook is 500 pages, but TurboLearn AI makes podcasts of each chapter so I can listen during my long commutes or workouts.

I always wanted to journal but was never consistent — life just got busy. Now I just talk to TurboLearn AI for 2 mins every night, and it turns my thoughts into neat daily entries automatically.
