Genetic algorithms require you to create a population where the genetic operators are applied (mutation, crossover and selection).

Creating a population of neural networks implies having multiple slightly different copies of the neural network to be optimized (i.e.: the population).

This can be more computationally expensive than other techniques which will do all the learning "in-place".

Yep, or a mix between the two.

GLM-130B quantized to int4, OPT and BLOOM int8,

https://arxiv.org/pdf/2210.02414.pdf

Often you'll want to keep the first and last layer as int8 and can do everything else int4. You can quantize based on the layers sensitivity, etc. I also (vaguely) recall a mix of 8bit for weights, and 4bits for biases (or vice versa?),

Here is a survey on quantization methods, for mixed int8/int4 see the section IV. ADVANCED CONCEPTS: QUANTIZATION BELOW 8 BITS

Here is a talk on auto48 (automatic mixed int4/int8 quantization)

Evolved antenna

>In radio communications, an evolved antenna is an antenna designed fully or substantially by an automatic computer design program that uses an evolutionary algorithm that mimics Darwinian evolution. This procedure has been used in recent years to design a few antennas for mission-critical applications involving stringent, conflicting, or unusual design requirements, such as unusual radiation patterns, for which none of the many existing antenna types are adequate.
