Поговорим про ML. Пару дней назад вышла новость о том, что в продажу поступила первая русскоязычная книга, половину текста в которой написала нейросеть ruGPT-3. А до этого вы все наверняка натыкались на очень яркие записи про Dalle и Imagen, где нейросеть по описанию рисует картинку, и получается очень любопытно. Такими темпами скоро нейросети превратятся в крипту: высокотехнологичную вещь, о которой, однако, в среде приличных технарей лучше не упоминать. Потому что то, каким образом это используется, и то, какой образ этому создают в массах, расходится не только с реальностью, но и с определённым уровнем вменяемости. Кстати, ML ещё и может ярко демонстрировать эффект Даннинга-Крюгера. Мем про "Ты чё, пёс, я математик!" нифига не шутка. Человек может считать себя крутым программистом, если научился комбинировать чужие библиотеки на питоне. Хотя на самом деле простейшую практическую задачу решить не способен -- я с такими сталкивался лично. ML-щики вообще пихают свои нейросети куда ни попадя, считая, что это волшебная таблетка и швейцарский нож для любых ситуаций. Мне рассказывали случай, когда на хакатоне по работе с данными выиграл человек, который просто аккуратно вручную подобрал нужные зависимости в Excel :) Глобально же нейросетями пытаются решать три вида задач: 1. Информации в вопросе много, а в ответе нужно мало. Например, распознавание образов и символов. Подбор значений каких-нибудь коэффициентов. Приложение "Хотдог или не хотдог" из сериала Кремниевая Долина. Обычно нейросети справляются с таким очень хорошо. Рукописный ввод распознают шикарно, по фото могут назвать породу собаки, математические формулы читают. Но важно понимать, что под капотом даже у такой нейросети не возникает никаких понятных вам символов. Например, при распознавании рукописного ввода случайный набор пикселей, не имеющий для человека смысла, может быть с той же степенью уверенности интерпретирован нейросетью, как совершенно чёткая буква А. Просто мы на такой случайный набор не попадаем почти всегда, и поэтому всё ок. 2. Информации в вопросе средне, и в ответе нужно средне. Как правило, это предсказание, восстановление недостающих данных, улучшение качества фото, раскрашивание ч/б. С такими задачами нейросети справляются уже средненько. Улучшенный нейросетью снимок сразу видно. Предсказание лишь ненамного точнее, чем случайный выбор. Польза в том, что в обращении такие сети просты, а результат всё-таки дают. Но не стоит их переоценивать. Например, сюда можно отнести задачу суммаризации текста (по большому объёму текстов тебе печатают выжимку). Мои товарищи в одном чате несколько дней игрались с ботом-суммаризатором, и в основном половина написанных им фраз это просто мусор и ерунда для ржача. Но в другой половине всё-таки какой-то совсем небольшой смысл проглядывался. Недостаточный для того, чтобы задалбывать этим ботом участников чата (привет, ребята :) ), но не абсолютный рандом. 3. Информации в вопросе мало, а в ответе нужно много. Это генерация данных: вот как раз написание текстов, составление рисунков, логотипов и так далее. Так вот, по моему скромному, но всё-таки хоть немного компетентному мнению, в таких вопросах нейросети выдают полную херню. И хвалёная логотипная нейросетка Лебедева — тоже полная херня. И распиаренная GPT ничего толкового не пишет. Когда читаешь примеры в новостях-анонсах, сразу думаешь: "Вау, как круто!". Но когда пробуешь сам: ruGPT-3 по уровню осмысленности где-то чуть ниже "Яндекс.Рефератов", если помните такой сервис и суть его работы. Я не знаю, будут ли сети по созданию изображений работать так круто (сейчас доступа к ним ни у кого нет), но книга в соавторстве с человеком стала возможна только по той причине, что в качестве человека взяли Павла Пепперштейна, который берёт случайные комбинации словосочетаний и выдаёт это за литературу. Поверьте: человечество пока что в безопасности касательно захвата машинами. #dev

🔤🔤🔤🔤➖ These changes will come in ways that have repeatedly happened before. For example, from studying history, it’s easy to identify over-extended empires, develop indicators for how overextended they are, and see how overextended empires have suffered from being overextended. In looking at what is happening now, it is natural to examine what is happening with the U.S., which now has 750–800 foreign military bases in 70–80 countries (site note: China only has 1) and has commitments that create expensive vulnerabilities all over the world. To be sure, there is nothing precise about these indicators, the picture they paint, or the exact timing. For example, history has taught us that wars don’t always have definitive start dates with big military events followed by clear declarations of war. The Assassination of Archduke Ferdinand, the German invasion of Poland, and the bombing of Pearl Harbor are actually the exceptions. Economic, financial, and military conflicts typically arise before there are clearly declared wars. Historically, major wars were typically preceded by developments and indicators like military stockpiles and monies being drawn down; budgets, debts, money printing, and capital controls being built up; rival countries observing the countries fighting and learning what their strengths and weaknesses are; and the overextended leading world power facing the challenge of trying to fight wars on different fronts that are very far apart. These factors all matter, and my measures of them indicate that we should be concerned. The classic dynamic at this stage is for conflicts to intensify rather than subside, so what happens next will be influenced by how the U.S.-Iran war goes. For example, there is already less confidence among some countries that the U.S. will defend them, which, when combined with the recognition that nuclear weapons are a great defensive as well as offensive power, is leading to more talk among countries’ senior policy makers about obtaining nuclear weapons and building up their stockpiles of them and other weapons, particularly missiles and missile defense systems. #dalio#iran#trump#nuclear#weapons#military#bases 📱American Оbserver - Stay up to date on all important events 🇺🇸

🔤🔤🔤🔤➖ Most of these wars involve major nuclear powers, and there are also significant non-shooting wars (i.e., trade, economic, capital, technology, and geopolitical influence wars) that most countries are in. Together, these conflicts make up a very classic world war that is analogous to past “world wars.” For example, past “world wars” consisted of interrelated wars that were generally slipped into without any clear start dates or declarations of war. Those examples of both past and current wars combine in a classic world war dynamic that affects them all. Understanding how the sides are lining up and what their relationships are is very important. It is quite easy to see objectively how the sides are lining up via indicators such as their treaties and formal alliances, their votes at the U.N., their leaders’ statements, and their actions. For example, one can see how China is aligned with Russia and Russia is aligned with Iran, North Korea, Cuba, and Venezuela, and how that group is largely opposed to the United States, Ukraine, most European countries, Israel, the GCC states, Japan, and Australia. These alliances matter a lot in imagining how things will go for the relevant players, so they need to be considered when observing what’s going on and what’s likely to happen. For example, we see that reflected in China’s and Russia’s votes at the U.N. on Iran needing to open the Strait of Hormuz. Similarly, while it’s said that China is particularly harmed by the closing of the Strait of Hormuz, that is wrong because China’s mutually supportive relationship with Iran will probably allow oil going to China to get through. Plus, China’s relationship with Russia will ensure China gets oil from Russia. China also has a lot of other energy (coal and solar), and it has a huge inventory of oil. Also noteworthy is that China consumes between 80% and 90% of Iran’s oil output, which adds to the power of its relationship with Iran. All things considered, it appears that China and Russia are the relative economic and geopolitical winners from this war. Though to be sure, the United States is relatively advantaged in terms of global energy economics, because it is in the enviable position of being an energy exporter. Studying history is immensely valuable to me and helps me contextualize current events. For example, both an examination of several analogous cases in history and logic make it obvious that how the United States (the dominant power of the post-1945 world order) performs in the war with Iran (a middle power), how much money and military equipment it expends and depletes itself of, and how well it defends (or doesn’t defend) its allies will be watched by other nations and will enormously influence how the world order changes. Most importantly, we know that what happens in the war with Iran will have huge implications for what other countries (most importantly, those in Asia and Europe) will do, which will have big implications for how the world order will change. #dalio#iran#trump#nuclear#weapons#military#bases 📱American Оbserver - Stay up to date on all important events 🇺🇸

Ray Dalio: The Great Investor On the War in Iran and the Contemporary World 🔤🔤🔤🔤➖ As a global macro investor for over 50 years who has needed to study all things that affected markets over the last 500 years to know how to deal what’s coming at me, it appears to me that most people tend to focus on and react to the attention-grabbing things that are going on at the time—like what is going on with Iran now—and miss the much bigger, more important, and longer-term-evolving things that are driving what is going on and what is likely to happen. For instance, this week, headlines have focused on the recently announced two-week ceasefire of the U.S.-Israel-Iran war. But I believe the conflict in Iran is just one part of a larger potential world war, with countries like China, Russia, and Iran on one side and the United States and countries with U.S. military bases on the other. I wish it were not true, but I fear we are entering a world war. I wish it were not true, but I fear we are entering a world war. Certainly, what will happen with the Strait of Hormuz (most significantly, whether control of passage through it will be taken away from Iran, and which countries are willing to spend how much blood and treasure to make that happen) will have many enormous repercussions all around the world. There are also the issues of whether Iran will still have a capacity to inflict harm on its neighbors through missiles and nuclear weapons, of how many troops the U.S. will send to the region, of the cost of gasoline, and of the upcoming U.S. midterm elections. All these near-term issues are important, but they lead people to miss the really big, even more important things. More specifically, because most people tend to have this short-term perspective, they now expect, and the markets are pricing in, that this war won’t last long, and when it ends, that we will get back to “normal.” Virtually nobody is talking about the fact that we are in the early stages of a world war that isn’t going to end any time soon. Interconnected conflicts It may sound like hyperbole to say we are in a world war, but it is indisputable that we are now in an interconnected world that has a number of shooting wars going on (e.g., the Ukraine-Russia- Europe-U.S. war; the Israel-Gaza-Lebanon-Syria war; the Yemen-Sudan-Saudi Arabia-UAE war that also involves Kuwait, Egypt, Jordan, and other related countries; and the U.S-Israel-GCC-Iran war). #dalio#iran#trump#nuclear#weapons#military#bases 📱American Оbserver - Stay up to date on all important events 🇺🇸
