Welcome to the staging ground for new communities! Each proposal has a description in the "Descriptions" category and a body of questions and answers in "Incubator Q&A". You can ask questions (and get answers, we hope!) right away, and start new proposals.

Are you here to participate in a specific proposal? Click on the proposal tag (with the dark outline) to see only posts about that proposal and not all of the others that are in progress. Tags are at the bottom of each post.

Incubator Q&A What are the support vectors in a soft-margin SVM

I know what Support Vector Machines (SVMs) are and how they work, but I regularly get confused by what exactly the support vectors are. In case of linearly separable data, the support vectors are ...

Incubator Q&A Why can't we use linear regression on logits for solving logistic regression problems?

Consider a machine learning problem with inputs $\boldsymbol{X} \in \mathbb{R}^{N \times D}$ and corresponding labels $\boldsymbol{y} \in \mathcal{Y}^N$. When the problem is to solve a regression ...

Incubator Q&A Is LLM fine tuning the same as transfer learning?

TL;DR: Fine-tuning is not the same as transfer learning, but is often a part of transfer learning. The goal of transfer learning is to "transfer" information from one model to some other model. T...

Incubator Q&A Do Large Language Models "reason"?

I am afraid that the answer to your question is actually quite simple: there is no consensus among scientists. This is illustrated by the fact that the "fathers of Deep Learning" do not entir...

Incubator Q&A What are the support vectors in a soft-margin SVM

The goal of a soft-margin or C-SVM is to solve the following minimisation problem: $$\min_{\boldsymbol{w}, b} \frac{1}{2} \|\boldsymbol{w}\|^2 + C \sum_i \xi_i$$subject to $$\forall i : \begin{al...

Incubator Q&A What is the technical term for converting a sound recording to a phoneme vector?

I am no specialist on audio processing, but I believe the general task of converting raw audio to discrete symbols is called transcription. However, this does not distinguish whether these symbols...

Incubator Q&A Why can't we use linear regression on logits for solving logistic regression problems?

There is the obvious answer that points out that since $y \in \{0, 1\}$, we would end up with invalid values for computing the logits. However, by transforming the labels to have values $\tilde{y}...
