### Are there improvements on Dana Angluin's algorithm for learning regular sets

In her 1987 seminal paper Dana Angluin presents a polynomial time algorithm for learning a DFA from membership queries and theory queries (counterexamples to a proposed DFA). She shows that if you are ...

### Learning juntas, with membership queries

The junta problem is the following: we have a boolean function $f:\{0,1\}^n \to \{0,1\}$ that actually happens to depend on only $k$ of its input variables. Given the value of $f(x)$ for many random ...

### AdaBoost - why using such alpha function?

I'm reading the paper where AdaBoost was invented (link), and I couldn't understand why they have chosen the formula α_t = 1/2 * ln((1-ε_t) / ε_t). snippet: ...

### Geometric intuition behind VC-dimension

Recently, I learnt about VC-dimension and how its boundedness assures PAC learnability on uncountable range spaces (let's assume that hypothesis class is the same as the family of concepts we want to ...
