Episode notes
INSIGHT

Vanishing Gradient Problem

  • The vanishing gradient problem hindered the development of both recurrent and deep neural networks.
  • This problem prevented effective learning by making gradients too small during backpropagation.
INSIGHT

LSTM Solution

  • LSTMs solved the vanishing gradient problem with a memory cell.
  • This cell maintains constant credit assignment, enabling information storage over long sequences.
ANECDOTE

LSTM Adoption

  • LSTMs were widely adopted, powering technologies in cell phones and virtual assistants.
  • Companies like Apple, Google, Amazon, and Alibaba integrated LSTMs into their systems.
