am going to do topic modeling via LDA. I run my commands to see the optimal number of topics. The output was as follows: It is a bit different from any other plots that I have ever seen. Do you think ...

I have a dataset that has the following columns:
The variable I'm trying to predict is "rent".
My dataset looks a lot similar to what happens in this notebook. I tried to normalize the rent ...

I'm trying to understand what I did wrong when trying to answer this question. The exact question is:
Assume that we have 3 trained prediction models, and each model outputs either
-1 or 1. We then ...

This may seem to be a silly question. But I just wonder why the MAE doesn't reduce to values close to 0.
It's the result of an MLP with 2 hidden layers and 6 neurons per hidden layer, trying to ...

I have read a paper on Negative Learning: https://arxiv.org/abs/1908.07387.
The idea is that you can train a network not only by telling what label of the sample is, but by telling what it surely is ...

I thought both, PReLU and Leaky ReLU are
$$f(x) = \max(x, \alpha x) \qquad \text{ with } \alpha \in (0, 1)$$
Keras, however, has both functions in the docs.
Leaky ReLU
Source of LeakyReLU:

How to calculate the mAP (mean Average Precision) for the detection task for the Pascal VOC leaderboards?
There said - at page 11:
Average Precision (AP). For the VOC2007 challenge, the interpolated

I am using K-Means for a binary classification problem in labelled data.
I think that K-Means used opposite labels to mine for the output variable.
I calculated the ARI to better understand if the ...

Suppose we want to learn the Boolean function in instance space $X=\{0,1\}^3$. We are given two models to examine: $H_1$ is a set of all logical functions in the conjunctive normal form (CNF), $H_2$ ...
