Abstract:  In the ML reading group this Friday, we will look at a circuit model (or "architecture") called "transformer" that ostensibly underlies recent popular applications such as ChatGPT, Bard and friends. We, however, will focus on works (mostly empirical as of now) that attempt to understand its power in the more restricted setting of learning to "reason" in the setting of a restricted proof system. Two examples we will look at are

1) Straight Line Programs
2) Proofs in the Isabelle proof system.
