Episode notes
Societal Gatekeeping of AI
- Society needs to understand the math behind AI to be informed gatekeepers.
- This understanding reveals AI's power and limitations, enabling better decisions and bias detection.
The Perceptrons' Impact
- The Perceptrons book by Marvin Minsky and Seymour Papert dampened neural network research in the late 1960s.
- It showed single-layer networks couldn't solve the XOR problem, suggesting multi-layer networks might also fail.
K-Nearest Neighbors and Dimensionality
- The K-Nearest Neighbors algorithm classifies data points by proximity to other labeled points.
- This powerful method suffers from the curse of dimensionality as data dimensions increase.
