Here, we show that the Hassenstein-Reichardt Correlator can be reformulated as a transformer with a heterogeneous value function.

Here, I list mathematical formulations of Gaussian theories and a scalar field theory with anharmonic fourth order interactions. This is for my own reference but might also be useful for someone else. All materials here are copied from the Chapter I.7 of A. Zee’s QFT book with some typos corrected.

This is an informal study note about the transformer, and the goal is to lay out the mathematical details for a sequence-to-sequence task.
