The Math Behind Neural Networks, Part 2.1 — Output Units and the Birth of the Sigmoid — Hussein Mahdi Al-Rubaie

Output units turn features into answers. A linear unit predicts a Gaussian's mean, giving squared error. For yes/no, log-linearity plus exp and normalization derive the sigmoid and its Bernoulli.

GPT-6 Astra Breaks an Old Enigma Message

This is pretty amazing: However, the most astonishing thing about this break is that the GPT­6 Astra did it entirely on its own. Carter Leffer only directed GPT­6 Astra to see if it could break any of the unbroken Enigma messages published on the Crypto Cellar Research web page. After analysing the unbroken messages on the website, it decided that the most promising message was Nr. 172, MVUEH and it also quickly suspected that the plaintext of Nr. 173, SIPVX, might be related to the plaintext of the unbroken MVUEH message. After trying many different approaches, GPT­6 Astra focused on using the repeated place name ROSENOW ROSENOW as a crib. After developing the necessary Python and C++ software for an Enigma simulator and an Enigma Bombe, GPT­6 Astra started a thorough break with the ROSENOW crib, which in the end resulted in the correct key and plaintext for the MVUEH message being found...
