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.

📰 Paper reading club: PPO experience report
postponed for a week due to the wind!

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.

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.

📰 Paper reading club: genetic censorship circumvention, CPU backdoors

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. The talks will be given in English, discussion in En/Ru.

1. Automatic Censorship Evasion

Internet censorship becomes ever more advanced. Geneva is an approach for automatically discovering censorship evasion strategies. Let's learn how it works!

2. Backdoors in VIA x86 CPUs

We find internal control registers can enable the user to bypass security mechanisms, e.g., allowing ring 0 access at ring 3 in some common commercial VIA CPUs. At the seminar, we'll discuss how deep we need to dig into CPU to find a hidden backdoor/bug and which instruments we have for this. Paper, talk.

ACT is a therapy identified by the American Psychological Association as an empirically supported treatment for depression, anxiety, and OCD.

But how much empirically supported? We examine classical results and recent critiques.
