Эластичная чистая регрессия Elastic Net — метод линейной регрессии, который сочетает преимущества двух регуляризаций: Лассо (L1) и Риджа (L2). Он помогает справиться с задачей отбора признаков и предотвращает переобучение, особенно когда данные содержат много коррелирующих признаков. Эластичная сеть использует комбинацию штрафов: L1-регуляризация (Лассо): способствует разреженности признаков (некоторые коэффициенты…

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

An ad marker, not a judgement about a post. A post is counted here because it carries one of two explicit markings: an erid token, which Russian law has required on paid placements since 2022 and which is issued against a specific advertising contract, or a #реклама / #ad hashtag in the body, which is the channel declaring it itself. The first is documentary; the second is a self-declaration and is weaker. No classifier reads the text and decides — nothing on this site guesses that a post is an advertisement.
This is a floor, and it can only ever be a floor.A channel that runs paid placements without marking them produces no marker for us to count, and an unmarked ad is indistinguishable from an ordinary post on the public surface. The ad load above therefore means “the share of posts that declared themselves”, never “the share of posts that were paid for”. A low figure is not evidence of a channel that runs few ads.
Both figures are medians, and no ratio between them is published. Each is a view reading that actually occurred on a post, picked by percentile_disc rather than averaged, so one viral post cannot move it and no interpolated value is invented between two readings. The sample on one side is under five posts, which is too thin to compare. The two figures are shown side by side with the count behind each, and deliberately not divided into a headline like “ads get x% fewer views” — an arithmetic that is easy to print and, at this sample size, means nothing.

A token repeated across several posts is one advertising contract placed more than once, which is what the identifier is for. The strings are reproduced exactly as they appeared in the post or in its click-through URL and are not validated against any registry — we record the marker a channel published, and whether it resolves to a real contract is a question for the register that issued it.
Measured over the 21 most recent posts we hold, published 8 April 2026 to 12 August 2026. Views are the latest single reading held for each post, and any reading at or above 1,000 is rounded by Telegram to three significant figures.

Лассо-регрессия Lasso Regression — это метод линейной регрессии, который включает регуляризацию для уменьшения сложности модели и предотвращения переобучения. Название "Лассо" происходит от "Least Absolute Shrinkage and Selection Operator", что подчеркивает две основные функции этого метода: сжатие коэффициентов и отбор признаков. В отличие от ридж-регрессии, которая добавляет штраф на сумму квадратов коэффициентов…
Ридж-регрессия Ridge Regression — это метод линейной регрессии, который используется для анализа данных, когда существует проблема мультиколлинеарности (сильной корреляции между независимыми переменными). Основная идея ридж-регрессии заключается в добавлении регуляризационного члена к обычной линейной регрессии, что помогает улучшить стабильность и предсказательную способность модели. В отличие от стандартной линей…

SVM с RBF ядром SVM с RBF ядром (радиальная базисная функция) — это метод машинного обучения для решения задач классификации и регрессии, который позволяет находить нелинейные границы между классами. RBF ядро особенно полезно, когда линейные модели не могут точно разделить данные, так как оно способно создавать сложные, нелинейные разделяющие поверхности. Принцип работы RBF ядра: RBF ядро трансформирует данные в вы…
SVM с линейным ядром Это частный случай метода опорных векторов, который используется для решения задач классификации или регрессии, когда данные могут быть линейно разделены. В SVM с линейным ядром задача состоит в том, чтобы найти гиперплоскость, которая наилучшим образом разделяет два класса данных с максимальным зазором (margin). Основная цель SVM — максимизировать расстояние между ближайшими точками двух класс…
Метод опорных векторов SVM (Support Vector Machine) — это алгоритм машинного обучения, используемый для задач классификации и регрессии. Он работает на основе нахождения гиперплоскости, которая наилучшим образом разделяет данные на различные классы. Гиперплоскость — векторное пространство с n измерениями может быть разделено с помощью гиперплоскости, которая является подпространством размерности n−1. В двухмерном п…
Логистическая регрессия Это статистический метод, используемый для моделирования зависимости между одной или несколькими независимыми переменными и бинарной зависимой переменной (например, "да/нет", "1/0", "успех/неудача"). Этот метод особенно полезен в задачах классификации, где необходимо предсказать вероятность принадлежности объекта к одной из категорий. Применение логистической регрессии: - Классификация: Лог…
Полиномиальная регрессия Это расширение линейной регрессии, которое позволяет моделировать более сложные зависимости между независимой переменной X и зависимой переменной Y.

Линейная регрессия (Linear regression) Один из простейший алгоритмов машинного обучения, описывающий зависимость целевой переменной от признака в виде линейной функции. Цель линейной регрессии — поиск линии, которая наилучшим образом соответствует этим точкам. Модель линейной регрессии выглядит следующим образом: Y = aX + b, где: X — независимая переменная, Y — зависимая переменная (предсказываемое значение), a — …
Set bits. Алгоритм Брайана Кернигана Для подсчета количества единиц в двоичном представлении целого числа, можно использовать алгоритм Брайана Кернигана.

Showing the 12 most recent of 21 posts we hold for @the_algorithms. 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.
Citation-graph rank
Citation-graph rank — 1,145,874 of 1,151,006entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
Mentions
Named by 1 registered channel — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
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.
