Generator functions and yield in JavaScript
This article has participated in the “Newcomer Creation Ceremony” activity, and together we will start the road to gold nugget creation. Generator functions and yield statements A generator function is a special type of function in JavaScript that produces multiple values incrementally, rather than returning all the results at once. Unlike ordinary functions, generator functions […]
<C++> reverse iterator
The adaptation of the reverse iterator is only used for the two-way iterator. For the one-way iterator implemented by the singly linked list, a reverse iterator cannot be constructed through adaptation. Why do we say the reverse iterator adapter? Because we only need to implement a reverse iterator template to implement its reverse iterators in […]

Confusing loss function and activation function in Pytorch [softmax, log_softmax, NLLLoss, CrossEntropy]
Article directory definition activation function softmax T-softmax log_softmax loss function NLL Loss CrossEntropy cross entropy Definition softmax: maps a sequence of values to a probability space (each element is distributed and all sums are 1) log_softmax: Take the logarithm on the basis of softmax NLLLoss: Calculate log_softmax and one-hot CrossEntropy: Measures the difference between two […]
Python Async: Async Iterators (15)
Move your little hand to make a fortune, give it a thumbs up! Iteration is a fundamental operation in Python. We can iterate over lists, strings, and all other structures. Asyncio allows us to develop asynchronous iterators. We can create and use asynchronous iterators in asyncio programs by defining an object that implements the aiter() […]
