This app can help you learn and practice different sign language transcription systems and orthographies. Check out the tracing practice and quiz modes. Currently, there are handshapes from HamNoSys, ASLWrite, Stokoe Notation, Sutton SignWriting, and one handshape font. HamNoSys, AKA the Hamburg Notation System, was designed for phonetic transcription of sign language in minute detail for research purposes. Stokoe Notation was the first system for writing ASL, and Sutton SignWriting is meant to be a practical orthography for many sign languages. ASLWrite was designed as a practical orthography for American Sign Language. There is also a handshape lookup tool, which can be used to search for a handshape using one system and fine the equivalent handshapes from the others here. Other features of these systems are coming soon. Orientation is available for HamNoSys and planned for Stokoe and Sutton SignWriting. Location, movement, and non-manuals are also planned for the future. This app is still in development! You are free to try out the different features. Mobile app versions are coming soon.

About

Learning Transformer

Features
Read full description

A Transformer, built by hand and shown one step at a time. Twenty-three screens follow "Attention Is All You Need" (Vaswani et al., 2017) in the paper's own order: a word becoming numbers, the three vectors, the scores, the softmax, four heads merged into one, the mask, the second attention, and the loop that writes one word at a time. What this is not: a trained model. Every weight here was set by hand, so that each one can be read in a single line. Nine numbers stand for a word instead of 512. One encoder layer and one decoder layer instead of six of each. Four heads, four words of vocabulary, one short sentence. What it is: the paper's arithmetic at a size you can check by hand. Every number on every screen is computed while you look at it — no videos, no quizzes, no account, no network. Steps 1 to 10 are free. Steps 11 to 23 are one purchase, made once and kept.

Verdict

The call

The clearest difference is in-app purchases: Sign Language Transcription at none against Learning Transformer's 1. Sign Language Transcription also leads on iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
