Argmax is a mathematical function that you may encounter in applied machine learning. For example, you may see “argmax” or “arg max” used in a research paper used to describe an algorithm. You may also be instructed to use the argmax function in your algorithm implementation. ...

What does argmax mean? Explain the meaning of \text{char}(\mathbb{F} ) =2 . Given \log_b 2 = \dfrac{1}{5}, what is \log_b 4? If \log_{x}(1/8) = -3/4, then what is x? If 2x = 360/4, what is x? What is 0.1732? What is \sin^{0}(x)? What does e^{-4...
Limg(S,L,L′)=−1|L|∑c∈Llog(Stcc)−1|L′|∑c∈L′log(1−Stcc)withtc=argmaxi∈ISic (2) The first part of Eq. (2), corresponding toc∈L, is used in [23]. It encourages each class inLto have a high probability on at least one pixel in the image. The seco...
Then, for the prediction step after learning the model, we just return the “argmax,” the index in the output vector with the highest value as the class label. That’s fine if we are only interested in the class label prediction. Now, if we want “meaningful” class probabilities, that...

In recent years, the “planning as inference” paradigm has become central to the study of behaviour. The advance offered by this is the formalisation of motivation as a prior belief about “how I am going to act”. This paper provides an overview of the
