About Artificial Neural Networks (ANNs):

  • ANNs are machine learning algorithms modelled after the human brain’s neural structure.
  • Composed of interconnected artificial neurons (nodes) that process information similarly to biological neurons.

Key Discoveries:

  • John Hopfield: Invented the Hopfield Network, designed to store and recall patterns, based on atomic spin physics.
  • Geoffrey Hinton: Developed the Boltzmann Machine, a network capable of identifying elements in data and creating new patterns using statistical physics.

Role of ANNs in AI:

  • Deep Learning: ANNs form the foundation of deep learning, handling large datasets and complex models.
  • Applications in AI: Used in image recognition, natural language processing, and autonomous systems for decision-making.
  • Learning from Data: For instance, ANNs can detect tumours by learning from thousands of medical images.
