F0RTHSP4CE

📰 Paper reading club: 3D compression, differential privacy

We come together to discuss advances in computer science, ground them down to applications, and see where to the wind is blowing. Read the papers at your own time and come discuss them with us. This seminar will be held in English.

1. 3D Data Compression
We'll talk about various tricks researchers & engineers came up with to efficiently store / stream various 3D data. We'll cover:

- Basics of Video Compression
- Animation / mesh compression : from GDC and a paper
- For 3D Gaussian Splatting: post1 and post2
- For video NeRFs

2. Differential privacy
DP is a framework for private data analysis at scale used by Apple and other bigtech to facilitate data analysis while minimising legal risk.

- Intro and statistical background
- Adaption to DL
- Validity analyses [1, 2]
- Tightening bounds

Music theory #18: random paper reading club

⏱ 19:00 PM Friday, 5 January
📍 F0RTHSP4CE, Khorava St 18 / Janashia, the basement

We'll continue our course on music theory (in Russian)

===

В этот раз будет встреча без подготовки, экспромт-фристайл-провал. Мы будем брать случайные статьи из журнала Music Theory Online, слушать музыку из них и пытаться понять, в чём же поинт авторов статьи. Забивать и идти к следующей статье.

Ноутбуки в этот раз не понадобятся - предлагаю разбирать статьи хором с проектора.

📰 Paper reading club: PPO experience report
postponed from 28/12 to 04/01 due to weather conditions!

In light of gales that fiercely spin,
We shift our date, not cowed, but keen.
With spirits high and safety first,
We'll meet anew, when winds disperse.

Primacy bias in PPO
"The Primacy Bias in RL" shows how we can improve sample efficiency and increase the expected return with weight resets. I will tell how we tried leveraging resets in PPO and analyzed primacy bias phenomena.

The plan:
- How to compare RL algorithms: "rliable" recommendations
- The Primacy Bias in RL: when resets work, and when they don't
- Resets in PPO: what we tried (spoiler: nothing worked)
- Heavy Priming experiment: overfitting on one batch at the beginning of the training. Differences between SAC and PPO, the probable cause of PPO stability.

Music theory #17: drums in MIDI and more on tokenization for LLMs

⏱ 19:00 PM Friday, 29 December
📍 F0RTHSP4CE, Khorava St 18 / Janashia, the basement

We'll continue our course on music theory (in Russian)

Продолжаем коллективно смотреть на реальные миди-файлы как проекции поп-аранжировок. Обсудим устройство ударных партий - поищем закономерности глазами.

Также продолжим разговор про то, как нам накормить нейросети мидями, чтобы они не подавились, поняли всю теорию музыки и рассказали нам. Сколько байт информации в трёхминутной песне - сто, тысяча или десять тысяч?

Ноутбук в этот раз не нужен. Приходите, даже если вы ещё у нас не были.

Drawing & stencil workshop
⏱ Monday, 25 December, 19:00
📍 F0RTHSP4CE, Khorava St, 18

On Monday we’re drawing and hand printing with stencils together with @boredtoad
Stenciling is very simple, yet gives you surprising results, be it a portrait of your favorite cup or a big abstract piece.
Bring sharp paper knifes, stamp pads, paint rollers or sponges if you have them!

---

В понедельник с @boredtoad вырезаем вручную трафареты из бумаги, тыкаем по ним валиком/ губкой и смотрим, как они апгрейдят даже самый простой рисунок. Уже уметь что-то необязательно, всё покажем и попробуем вместе.
Запасаем штемпельные подушки, острые ножи для бумаги, губки и валики, и начинаем эксперимент!

Music theory #16: should we tell MIDI LLMs anything about the tonic?

Музыка похожа на язык, а значит есть надежда, что трансформеры типа GPT разберутся в её структуре, если их накормить всей музыкой на свете. Но как их правильно кормить?

Начнём со статьи "Byte Pair Encoding for Symbolic Music", послушаем разные примеры нагенеренной музыки, обсудим архитектуру трансформеров. Затем посмотрим на реальные миди-файлы, поищем в них тонику и пообсуждаем, нужно ли трансформерам знать что-то о теории музыки.

📰 Paper reading club: recursing gradient descent, proving automatic differentiation

We come together to discuss advances in computer science, ground them down to applications, and see where to the wind is blowing. Read the papers at your own time and come discuss them with us.

1. Provably correct, asymptotically efficient, higher-order reverse-mode automatic differentiation

Reverse-Mode Automatic Differentiation for PyTorch programs? Sounds confusing! Let's start with Simply-Typed Lambda Calculus and Forward-Mode AD, and rederive from there... 😊

Check these slides for a connection with the second topic.

2. Gradient Descent: The Ultimate Optimizer

What if you didn't need to tune hyperparameters because you have AD, GD, and recursion? Stack towers of optimizers and scrap your Adam!

Bring your laptop and be ready to read, watch, train and test. Make the Basilisk proud of you

If you want some preliminary homework: lecture, exercises
