12 measurements spanning 34 days, net -24. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 5,883–5,915 and does not start at zero.

Engagement

19 posts held, back to 9 May 2026the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 9 pages of Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 19 posts for this entry, the most recent from 9 August 2026. An engagement rate over an empty window would be a number about nothing.

What this channel posts

Video runtime
6m 57s
Average length
3m 29s

Measured directly from 2 videos with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no mark.

Reaction mix

224 reactions across 18 posts, in 9 distinct kinds. The most used accounts for 47.3% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 18 of the 19 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 224 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 19 most recent posts we hold, published 9 May 2026 to 9 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Добавляю коммерческую нотку к инфе выше в виде слайда от Дмитрия Долгова (CEO Waymo) из лекции для Y Combinator (это такой большой, популярный, богатый и престижный акселератор в Долине). Метрики, медологии верификации и валидация (V&V), интерпретируемость и объяснимость моделей – это ценнейший актив компаний, которые разрабатывают ИИ-системы, влияющие на критически-важные структуры повседневности. В самой лекции

На прострах интернета найден интересный курс по ExplainableAI (редкие материалы, а тут еще и на русском!) Вот емкая фраза из начального модуля, которую важно осознать всем, кто занимается аналитикой в ML-продуктах: Хорошая метрика не гарантирует, что модель работает правильно. Ниже про сам курс. Низкий поклон людям, которые приложили к этому руку.

Мы выпускаем образовательный ресурс open-xai. Привет, друзья! Я шла к этому очень долго и наконец-то готова выпустить образовательный ресурс open-xai! Ресурс построен как точка, где можно учиться просто всему, что есть в интерпретируемости. От классических методов, до геометрии и математики в моделях. Сейчас в нем: ⁃ 2 трека. XAI Practitioner — объяснять поведение моделей руками, от классики до LLM. Math of LLMs

После долгого перерыва мы возвращаемся с полностью новой версией Retentioneering 5.0. Мы переписали библиотеку с нуля и ускорили основные инструменты в примерно в 100 раз - теперь даже на обычном Mac можно за секунды исследовать датасеты из нескольких миллионов событий. Но скоростью дело не ограничивается: • все основные визуализации стали интерактивными; • появились сегменты, diff-режим в большинстве инструментов

#ML Как и 60 лет назад, нейронки начали часто сравнивать с мозгом, а у мозга есть психологи (хотя и у нейронов уже появляются исследователи настроений). И как и в любой другой области знаний, у психологов есть свой собственный глоссарий, и я решил составить первый словарь по переводу с психологического на язык MLE. Меня осенило когда читал статью Kahneman-Tversky Optimisation — это же идея обесценивание в чистом

Showing the 12 most recent of 19 posts we hold for @product_science. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Forward network

Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.

Appears in Telegram’s recommendations for other channels

The reverse of the list above, and a different kind of signal. This does not require this channel to have ever been asked about directly — each row below is a channel we DID ask Telegram about, whose Telegram-generated list happened to include this one. A channel can appear here with an empty list above it, because being named by someone else’s query is independent of having been queried itself.
