Ранее я уже упоминал о другой фишке из ˍˍfutureˍˍ , это оператор деления. from __future__ import division Суть проста. Раньше сложность типа данных результата поределялась типом самого сложного операнда. Например: int/int => int int/float => float В первом случае оба операнда int, значит и результат будет int. Во втором float более сложный тип, поэтому результат будет float. Если нам требуется получить дробное значение при делении двух int то приходилось форсированно один из операндов конверировать в float. 12/float(5) => float Но с новой "философией" это не требуется. В Python3 "floor division" заменили на "true division" а старый способ теперь работает через оператор "//". >>> 3/2 1.5 >>> 3//2 1 То есть теперь деление int на int даёт float если результат не целое число. В классах теперь доступны методы __floordiv__() и __truediv__() для определения поведения с этими операторами. Данный переход описан в PEP238. #pep#2to3#basic

Lost in Translation: AI Explanations Biased Toward Western Cultures? A new study reveals a potential blind spot in AI development: cultural bias in explanations provided by AI systems. As AI plays an increasingly prominent role in decision-making (hiring, healthcare), explainable AI is crucial for user trust and understanding. Explainable AI systems aim to make complex AI models easier to understand by generating explanations for their outputs. The study analyzed over 200 explainable AI user studies, finding a significant bias towards explaining AI decisions in ways preferred by Western populations: Western cultures tend to favor internalist explanations, focusing on the AI's "thinking" or beliefs. Conversely, collectivist cultures might prefer externalist explanations, referencing rules or social norms influencing the AI's output. This bias could lead to: ✅ Reduced trust in AI systems from non-Western users who receive explanations that don't resonate with their cultural background. ✅ Exclusion of valuable populations from the benefits of explainable AI. 94% of studies reviewed showed no awareness of potential cultural variations in explanation preferences. 48% of studies didn't report the cultural background of participants. Studies sampling non-Western populations were scarce (8.4%). Even studies reporting cultural background often generalized findings to broader populations without considering cultural differences. As AI impacts people worldwide, AI systems need to cater to diverse cultural understandings of explanation. #AI#ExplainableAI#Culture#Bias
