A dynamical system with #memory with the ability to learn and adapt to its environment or to change it will need at most these three #control mechanisms:

1️⃣ The #internal immediate control (#regulation) of state variables essential for preserving the stability or #homeostasis of the system. This is a simple #reaction of the system to a perturbance, like, for example, sweating when the core temperature of the body increases beyond some preset margin.

2️⃣ The #proximal control of the surrounding environment is used when 1️⃣ is overwhelmed and there is a need for the coordinated engagement of different lower-level regulators, the #measurement (tracking), and negative #feedback control of multiple time-dependent variables like for example, when taking off layers of clothes, moving the body into a shade, or taking a cold shower until the temperature gets again within limits.

3️⃣ The #distal, long-term, open-loop control with delayed feedback is the highest form of control, like for example when building a house with an HVAC system that will remove the necessity for a continuous employment of proximal control (2️⃣) by creating a private controlled environment.

All #living systems feature this 3-layered control architecture, with the only difference being in what degree the activities on each level are the result of #conscious deliberation as opposed to a natural, innate behavior.

A Stochastic Proximal Polyak Step Size

Recently, the stochastic Polyak step size (SPS) has emerged as a competitive adaptive step size scheme for stochastic gradient descent. Here we develop ProxSPS, a proximal variant of SPS that can...
