Secret decoder ring

Excel Secret Decoder Ring - 2330

This started as an April Fools joke from Bill Szysz and Mike Girvin, but it brought back memories of Schoolhouse Rock from 1973 and the story of Little Twelve Toes. In today's video, a secret decoder ring in Excel using BASE and DECIMAL. Also: you can now assign fill color and font colors

Transformers - Part 7 - Decoder (2): masked self-attention

This is the second video on the decoder layer of the transformer. Here we describe the masked self-attention layer in detail. The video is part of a series of videos on the transformer architecture, https://arxiv.org/abs/1706.03762. You can find the complete series and a longer motivation

Steganography Tutorial - Hide Messages In Images

Steganography is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step further by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your data will fail to know it

Transformer - Part 8 - Decoder (3): Encoder-decoder self-attention

This is the third video about the transformer decoder and the final video introducing the transformer architecture. Here we mainly learn about the encoder-decoder multi-head self-attention layer, used to incorporate information from the encoder into the decoder. It should be noted that thi
