Deep Learning Revisions

It's always good to take a pause/revise / add a few more learning pointers :)


Key Notes
  • ML operates by handcrafted features
  • DL features learned directly from data
  • Data prevalent, Parallelizable models / hardware, GPU/ CUDA, TF / Pytorch
  • Activation functions and their differentiation


  • Non-Linear functions help to build boundaries






  • Text - sequence of characters / words
  • Stock prices / DNA sequences
  • Temporal dimension to models
  • Same series once for each Timestep
  • Horizontal to vertical view
  • Each output is connected/is input to the next timestamp
  • Internal memory / state-maintained


  • Individual Loss for each timestep
  • Backprop for all timestamps
  • Forward pass across time




  • Back propagate through time
  • Loss with respect to the internal state
  • Attention
