This code generates a sequence of random numbers and applies a transformation to each number, | |
such that the probability of the number being transformed to 1 increases as the sequence progresses. | |
This is done using a Markov chain with a transition matrix that depends on the sequence index. | |

This code defines a transformer-based neural network and applies it to a Markov simulation over a sequence of random numbers. | |
The Markov simulation generates a sequence of states by applying a transformation to each state using the given model. | |
The transformation probability depends on the current state and the current sequence index. |
