Оператор pipe позволяет писать более компактный код, реализуя логику объединения данных (Union). Важно помнить, что его поведение зависит от контекста. Побитовые операции (логическое OR) result = 5 | 3 # 5 (0101) | 3 (0011) = 7 (0111) Самое главное - не путать с оператором or, это другое! Объединение множеств set_a = {1, 2, 3} set_b = {3, 4, 5} set_c = set_a | set_b # {1, 2, 3, 4, 5} set_c |= {5, 6} # {1, 2, 3, 4, 5, 6} Слияние словарей dict_1 = {"a": 1, "b": 2} dict_2 = {"b": 3, "c": 4} merged = dict_1 | dict_2 # {'a': 1, 'b': 3, 'c': 4} merged |= {"d": 5} # {'a': 1, 'b': 3, 'c': 4, 'd': 5} Аннотации типов, заменяет Union def process_data(value: int | str) -> None: print(value) Допустимо использовать в isinstance или issubclass isinstance(3, int | float) # True Паттерн-матчинг status_code = 404 match status_code: case 200 | 201 | 204: print("OK") case 400 | 404 | 500: print("ERROR") Для использования в своих классах требуется переопределить метод __or__ Так же нашел библиотеку pipe которая добавляет еще много возможностей. Рекомендую ознакомиться ;) #basic

#ML#self-supervised #representation Contrastive loss is widely used in representation learning. However, the mechanism behind it is not as straightforward as it seems. Wang & Isola proposed a method to rewrite the contrastive loss in to alignment and uniformity. Samples in the feature space are normalized to unit vectors. These vectors are allocated onto a hypersphere. The two components of the contrastive loss are - alignment, which forces the positive samples to be aligned on the hypersphere, and - uniformity, which distributes the samples uniformly on the hypersphere. By optimization of such objectives, the samples are distributed on a hypersphere, with similar samples clustered, i.e., pointing to the similar directions. Uniformity makes sure the samples are using the whole hypersphere so we don't waste "space". References: Wang T, Isola P.

The Bechdel-Wallace Test checks if a movie or story has at least two women who talk to each other about something other than a man. It shows how women are often missing or only shown in relation to men. Many films fail this simple test, highlighting the need for better female representation in media. 👱‍♀👩‍🦳🚫🤷‍♂ [Read more] [See more] @googlefactss #BechdelWallaceTest🎬#WomenInFilm#Representation#Equality
