	Description: In this blog post, I share about a few open source project
	related to machine learning that I absolutely love.

	# Introduction

	I recently got interested into what's possible with machine learning
	programs, and this has been an exciting journey. Let me share about a
	few programs I added to my toolbox.

	They all work well on NixOS, but they might require specific
	instructions to work except for upscayl and whisper that are in
	nixpkgs. However, it's not that hard, but may not be accessible to
	everyone.

	# Whisper

	This program analyzes audio content of an audio or video file, and make
	a transcript of it. It supports many languages, I tried it with
	English, French and Japanese, and it worked very reliably.

	Not only it creates a transcript text file, but it also generates a
	subtitles (.srt) file, you can create video subtitles automatically.
	It has a translation function which pass all the transcript text to
	Google translate and give you the result in English.

	It's quite slow using a CPU, but it definitely works, using a GPU gives
	an 80 times speed boost.

	It requires a weight to work, it exists in different sizes: tiny,
	small, base, medium, large, and each has an English only variant that
	is smaller. It will download them automatically on demand in the
	~/.cache/whisper/ directory.

	# Stable-diffusion

	This program can be used to generate pictures from a sentence, it's
	actually very effective. You need a weight file which is like a
	database on how to interpret stuff in the sentence.

	You need an account on
	https://huggingface.co/CompVis/stable-diffusion-v-1-4-original to
	download the free weight file (4 GB).

	# DeOldify.NET

	This program can be used to colorize a picture. The weights are
	provided. This works well without a GPU.

	I tried to use it on mangas, it works to some extent, it adds some
	shading and identify things with colors, but the colorization isn't
	reliable and colors may be weird. However, this improves readability
	for me 👍🏻.

	# Upscayl

	This program upscales a picture to 4 times its resolution, the result
	can be very impressive, but in some situation it gives a "plastic" and
	unnatural feeling.

	I've been very impressed by it, I've been able to improve some old
	pictures taken with a poor phone.

	# Going further

	If you know some tools in that kind that could interest me, please
	share! :) Especially if it's something to colorize mangas 😁.
