A project that could be really interesting is to make a Lua interface for
some of the new neural nets, especially based on the Tsetlin-engine. Sounds
nifty, but it is nothing more than a slight reformulation of an old
learning algorithm (type early 70th), where the old algorithm has problem
converging for bad training data (ie. not separable). What is really nice
is that a trained network is extremely efficient, as it is mostly just
bit-operations or add-operations. Which means we can make rather fancy
classifiers that run in the web servers, and thus without any delayed
update of the pages.
The bad thing is that the training must be done offline, because that is
nowhere near lightweight.
Ordinary classifiers seems to work well, that is equivalents to fully
connected layers. Also some types of convolutional layers. Some regressions
can be done, but the networks are binary in nature, and mapping to and from
linear scaling adds complexity.
But running neural nets inside a PHP-based web server… I doubt we would hit
the 10 sec limit for a Lua module even if we added several such networks.
Ok, to much coffee today…
