However, if instead, each state can output different symbols where each symbol is associated with a certain probability, then the outputs are non-deterministic (hidden) and the resulting model is called Hidden Markov Model (HMM). At a high level, a HMM is a Markov model with Markov transition process and non-observable (hidden) states.

In this work, we propose Heima (as hidden llama), an eficient reasoning framework that leverages reasoning CoTs at hid-den latent space.

A claim was submitted, a payment arrived—or didn't—and the case closed. Rarely does anyone stop to ask whether the payment that came in matched what the contract
