👑 Конец режима: Как идентифицировать переход из одного режима экономики в другой в реальном времени?

Алгоритмов сегментации временных рядов много, но сейчас нас устраивает следующий подход из двух шагов:

1. Сегменитируем временной ряд на кусочки "стационарных" распределений показателя по рецепту из Heuristic Segmentation of a Nonstationary Time Series Bernaola-Galv´an et al. [Phys. Rev. Lett. 87, 168105 (2001)]

2. Собираем нарезанные "отрезки" ряда в режимы на основе KNN кластеризации распределений показателя

Поделитесь своими рецептами идентификации перехода экономики между режимами - напишите, если интересно посмотреть на код

Telegram | DID YOU KNOW?

Date: |

Since January 2022, the SC has received a total of 47 complaints and enquiries on illegal investment schemes promoted through Telegram. These fraudulent schemes offer non-existent investment opportunities, promising very attractive and risk-free returns within a short span of time. They commonly offer unrealistic returns of as high as 1,000% within 24 hours or even within a few hours. At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. Also in the latest update is the ability for users to create a unique @username from the Settings page, providing others with an easy way to contact them via Search or their t.me/username link without sharing their phone number. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. Friday’s performance was part of a larger shift. For the week, the Dow, S&P 500 and Nasdaq fell 2%, 2.9%, and 3.5%, respectively.
