El Hashing o Message Digest es una función matemática a la cual le damos un INPUT, y nos devuelve un OUTPUT fijo del mismo tamaño y único para ese INPUT en específico.

Ese INPUT pudiera ser una imagen, un audio, una contraseña o cualquier tipo de archivo que tengamos. Digamos que tenemos la contraseña 123Abc, y tenemos la contraseña 123abc ambas las pasamos por la función hashing de MD5.

Can you explain to me how a neural network works?

YES and NO. Yes but it is not one of those topic which u can learn in a 15 minutes reading. So this will be a Yes(only overview).

Machine learning is the science that create software that can learn from previous experiences, and a artificial neural network (ANN) is a imitation game.

Sanity check — Do you understand all the words in this image? Can you add a few more words to this soup?

  • Ricoh MPC 306Z — use toner C406
  • Ricoh MPC 3004 — use toner C406
