We prove new bounds on the Betti numbers of real varieties and semi-algebraic sets that have a more refined dependence on the degrees of the polynomials defining them than results known before. Our method also unifies several different types of results under a single framework, such as bounds depending on the total degrees, on multi-degrees, as well as in the case of quadratic and partially quadratic polynomials. The bounds we present in the case of partially quadratic polynomials offer a… Expand
Bounds on the individual Betti numbers of complex varieties, stability and algorithms
TLDR
Graded bounds on the individual Betti numbers of affine and projective complex varieties are proved and certain homological and representational stability results for sequences of complex projective varieties which could be of independent interest are proved. Expand
Betti Numbers of Random Hypersurface Arrangements
We study the expected behavior of the Betti numbers of arrangements of the zeros of random (distributed according to the Kostlan distribution) polynomials in $\mathbb{R}\mathrm{P}^n$. Using a randomExpand
On generalizing Descartes' rule of signs to hypersurfaces
TLDR

On the equivariant Betti numbers of symmetric definable sets: vanishing, bounds and algorithms
Let $$\mathrm {R}$$R be a real closed field. We prove that for any fixed d, the equivariant rational cohomology groups of closed symmetric semi-algebraic subsets of $$\mathrm {R}^k$$Rk defined byExpand

This is an experimental case study in real algebraic geometry, aimed at computing the image of a semialgebraic subset of 3-space under a polynomial map into the plane. For general instances, theExpand
Topology of deep neural networks
TLDR
The goal is to shed light on two mysteries in deep neural networks: (i) a nonsmooth activation function like ReLU outperforms a smooth one like hyperbolic tangent; (ii) successful neural network architectures rely on having many layers, even though a shallow network can approximate any function arbitrary well.

TLDR
This article generalizes the characterization of non-negative symmetric polynomials by adapting the method of proof developed in Riener (2013) and deduces that in the case of a fixed degree it is possible to derive a method to test for convexity which makes use of the special structure of (multi-)symmetric poynomials.
