fly-mania

A fly plays the rhythm game osu!mania on four keys, and the accounting of what learns is clear: a fixed MaleCNS subgraph of 3,418 neurons and 242,111 synapses is never modified, and a small controller of four GRUs with 352,971 parameters is what trains. Perception is causal, a retina of four lanes by 128 rows plus 40 ms of past audio, with no access to the chart or note timings. Training is imitation via DAgger from a teacher that exists only during training, with no reward. The keys are pressed through a NeuroMechFly body with 16 ms of actuator delay and jitter.
