**Boltzmann machine**, a predecessor of modern machine learning models, is based on a spin-glass model of Sherrington-Kirkpatrick's stochastic Ising Model.**Nerves**, a construct of Δech cohomology theory, can be used to track down attractors in spike train activity in computational neuroscience?**The loss function**landscape pertaining to can be thought of thermodynamically as an energy function over thermal degrees of freedom? Stochastic gradient descent then acts as a dissipative process introducing self-generated disorder.*Any real function on a***cotangent bundle**can be interpreted to be a Hamiltonian, so real-valued cotangent bundle is a phase space.*A***more general form**of**Arrow's impossibility theorem**can be shown to be true as a consequence of homotopy.*A recent model called***rapid freeze neuroplasticity**, a phenomenon similar to frozen random patterns in coupled map lattices pertaining to self-organized**quenched disorder**, was proposed as an explanation for neurodynamics of conspiracy theories?*Philip J.

Cellular sheaves thus have natural variational approximations.
