Researchers have investigated how Llama-3.1-8B handles cyclic concepts, such as determining months in a year. They discovered that the model does not directly compute modular arithmetic based on the concept's cycle. Instead, it uses a general base-10 addition mechanism and then maps the result back into the cyclic space. This process involves a small set of specialized neurons that compute sums for different Fourier features, highlighting the interplay between causal abstraction and feature geometry in language models.
