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 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 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}...
