Math

A matrix constructed using second-order derivatives of a function, therefore
the Hessian matrix has a similar meaning to second derivatives
Hij=2l(θ)θiθjH_{ij} = \frac{\partial^2l(\theta)}{\partial\theta_i\partial\theta_j}

Geometry

Using the Hessian matrix, we can determine whether a particular point of a function is convex, concave, or a saddle point
It performs a geometric transformation that makes the basic bowl shape more convex or concave
