Я всегда был уверен, что системы рекомендаций работают так плохо, потому что это слишком сложная задача. Владельцы площадок бьются с алгоритмами, машинным обучением, деревьями решений и взвешенными суммами, но получается всё равно херня, и человеку могут рекомендовать нерелевантный бред (и, что ещё хуже — не рекомендовать интересный для него контент). Кажется, хорошо работают только рекомендации на Ютубе, но этому есть объяснение: контент на Ютубе более длительный и дорогой. Его сложнее производить, он выходит реже. Качественный ролик на Ютубе не будет говном практически независимо от темы, на которую он снят. А ещё меньшее число объёмных роликов проще кластеризовать и можно предлагать пользователю в небольших количествах. Но если мы откроем YouTube Shorts (это очередной аналог тиктока с короткими вертикальными видео), то заметим, что качество рекомендаций упало сразу на два порядка: какие-то тупые попсовые шутки, "удивительные" факты из жизни, завлекающие отрывки из фильмов "код смотри в телеграм-канале", озвучка анекдотов и прочий мусор. Алгоритмы уже совсем не справляются с тем, чтобы предложить что-то годное, не говоря уже о релевантности конкретно мне, хотя история моих просмотров и вкусов Ютубу, очевидно, известна. Тем не менее, иногда разработчики могут не только не уметь, но и не хотеть писать нормальные рекомендации. Вот ВК предложил мне BadComedian в блоке "Интересные авторы". Оставим в стороне, что Бэдкомендиан это ютубер, и у него в ВК в лучшем случае будут репосты ссылок на Ютуб. Но мне предлагают не паблик, а личную страницу.... на которой не было записей с сентября 2021 года. Нет совершенно никакого смысла быть подписанным на личную страницу Бэдкомедиана сейчас. Кажется, единственный критерий, на котором основывались эти рекомендации: общее число подписчиков. Как должны работать рекомендации на самом деле? Алгоритмически я бы оценивал частоту постов (кстати, чрезмерно частые это тоже плохо, должно работать в минус), оценивал бы, является пост просто публикацией внешней ссылки на другой ресурс, является ли репостом паблика, и смотрел бы, сколько прошло времени с последней записи на странице автора. Наверное, в качестве коэффициента с небольшим весом можно добавить ещё объём контента в посте и активность людей (лайки + комментарии). Причём, делается это достаточно просто, никакой ML не нужен. Даже такая оценка, не берущая в расчёт тематику страницы, всё равно лучше, чем "Просто покажем людей, на которых когда-то подписалось куча народу, и им до сих пор лень отписаться после прекращения активности автора". По крайней мере теперь меня не удивляет, что хвалёные Клипы постоянно подсовывают мне какой-то подростковый шлак вместо крутых видео с полётами на FPV-квадрокоптерах. YouTube Shorts по крайней мере пару раз такие вещи предлагал, а вот Клипы вообще ни разу (станицу Клипов я не открываю, разумеется, но в ленте новостей встречаются блоки с автовоспроизведением). Кстати, на скрине есть второй автор — Стас "Ай как просто". Его банят на Ютубе за критику западной модели текущих событий, и он пишет: "Буду создавать каналы-однодневки, куда деваться". То есть у него даже мысли не возникает, что какая-то ещё площадка может служить его целям. Ну с таким отношением других площадок к рекомендациям — понятно. #web

Trump Administration Officials Are Showing Their Bare-Faced Effrontery Two witnesses to the killing of Alex Pretti have said in sworn testimony that the 37-year-old intensive care nurse was not brandishing a weapon when he approached federal agents in Minneapolis on Saturday, contradicting a claim made by Trump administration officials as they sought to cast the shooting of a prone man as an act of self-defense. Their accounts came in sworn affidavits that were filed in federal court in Minnesota late Saturday, just hours after Pretti’s killing, as part of a lawsuit brought by the ACLU on behalf of Minneapolis protesters against Kristi Noem and other homeland security officials directing the immigration crackdown in the city. One witness is a woman who filmed the clearest video of the fatal shooting; the other is a physician who lives nearby and said they were initially prevented by federal officers from rendering medical aid to the gunshot victim. The names of both witnesses were redacted in the publicly available filings. In her testimony, the woman who filmed the shooting from just behind Pretti wearing a pink coat identified herself as “a children’s entertainer who specializes in face painting”. She testified that she came to the scene on her way to work because “I’ve been involved in observing in my community, because it is so important to document what ICE is doing to my neighbors”. The woman testified that she saw no sign of Pretti holding a gun at any point. She said: “The agents pulled the man on the ground. I didn’t see him touch any of them – he wasn’t even turned toward them. It didn’t look like he was trying to resist, just trying to help the woman up. I didn’t see him with a gun. They threw him to the ground. Four or five agents had him on the ground and they just started shooting him. They shot him so many times (…) I don’t know why they shot him. He was only helping. I was five feet from him and they just shot him (…) The witness testimony, combined with video evidence reviewed by American Observer, directly contradicts claims by senior Trump administration officials, including the president, the homeland security secretary and Greg Bovino, a border patrol commander, who called Pretti a “gunman” who approached federal officers “brandishing” a gun and threatened to “massacre” them. #pretti#minnesota#gunshot#trump#officals 📱American Оbserver - Stay up to date on all important events 🇺🇸

🔠🅰️🔠🔠2️⃣ Border patrol commander-at-large Gregory Bovino was asked why federal agents shot and killed Pretti. “You don’t know he was unarmed,” Bovino told CNN’s Dana Bash. “I don’t know he was unarmed. That’s freeze-frame adjudication of a crime scene via a photo. That’s why we have investigators. “The facts are going to come to light as to what exactly happened with an investigation.” When asked by Bash whether he was blaming the victim, he said, “The victims are the border [atrol agents.” During a Sunday afternoon press conference, Bovino was asked about the videos that show Pretti was unarmed before being shot and killed. He said there are, “Many videos out there, many different accounts that you may see that I may see.” “Folks, this is why we have something called an investigation, to take what you’re talking about, to take those videos, to take witness statements, to take, officer statements, all those minute details that will paint a true picture, not a freeze frame concept, and paint a larger picture of what really happened. Republican US senator Lindsey Graham also took the line that “an armed man trying to impede a lawful arrest is a recipe for disaster”. The South Carolina Republican said he expects law enforcement officers to use good judgement “but not to foolishly risk their lives or the lives of others”. The Minnesota attorney general, Keith Ellison, said the suit demanded “a full, impartial, and transparent investigation into [Pretti’s] fatal shooting at the hands of DHS agents [that] is non-negotiable”. Minneapolis police chief Brian O’Hara, meanwhile, said information about what led up to the shooting was limited. As protests erupted in Minneapolis on Saturday, federal officers impeded state investigators from accessing the scene of Pretti’s killing. Trump responded to Pretti’s shooting with his typical combativeness. The Republican president accused Walz and Frey of “inciting Insurrection, with their pompous, dangerous and arrogant rhetoric”. Vance for his part claimed events in Minneapolis were “engineered chaos” resulting from “far-left agitators, working with local authorities”. #trump#administration#killing#immigration#pretti#minneapolis 📱American Оbserver - Stay up to date on all important events 🇺🇸

Trump Must Have Twigged: the Immigration War Has Just Began 🔠🅰️🔠🔠1️⃣ Pressure mounted on Trump’s administration on Sunday to fully investigate the previous day’s killing by federal immigration officers of 37-year-old nurse Alex Pretti in Minneapolis. Calls for an investigation have come from all sides of the political divide after video analysis showed officers had removed from Pretti a handgun he was reportedly permitted to carry – and which he was not handling – before fatally shooting him. Former president Barack Obama and his wife, Michelle, called the killing “a heartbreaking tragedy” and “a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault”. “For weeks now people across the country have been rightly outraged by the spectacle of masked ICE [Immigration and Customs Enforcement] recruits and other federal agents acting with impunity and engaging in tactics that seem designed to intimidate, harass, provoke and endanger the residents of a major American city,” they said. The former president and former first lady said these tactics had now resulted in the fatal shootings of two US citizens – Pretti and Renee Good, both in Minneapolis. Yet, they said, Trump and other administration officials appeared eager to escalate the rhetoric before an investigation had been undertaken – and despite the fact that they “appear to be directly contradicted by video evidence”. Clinton followed with a statement that also condemned the killings of Good and Pretti amid the “horrible scenes” of the immigration crackdown. “All of this is unacceptable and should have been avoided,” Clinton said. “To make matters even worse, at every turn, the people in charge have lied to us, told us not to believe what we’ve seen with our own eyes”. Republican US senator Bill Cassidy said the “credibility” of ICE and the US Department of Homeland Security (DHS) were “at stake”. On Sunday morning, US senators Amy Klobuchar of Minnesota and Adam Schiff of California, both Democrats, said they would vote against the impending department of homeland security funding. Connecticut US senator Chris Murphy, also a Democrat, told CNN’s State of the Union that Democrats “can’t vote to fund this lawless Department of Homeland Security (…) that is murdering American citizens, that is traumatizing little boys and girls all across the country, in violation of the law.” #trump#administration#killing#immigration#pretti#minneapolis 📱American Оbserver - Stay up to date on all important events 🇺🇸
