CPAL 2027

The Fourth Conference on Parsimony and Learning (CPAL 2027) will be held at Hitotsubashi Hall in Tokyo, Japan. CPAL 2027 invites theoretical, methodological, empirical, and systems contributions that make parsimony central to learning—through sparsity, low rank, symmetry, modularity, compressibility, or structured computation. The conference welcomes work on foundation, generative, multimodal, and agentic models when the underlying parsimony principle is explicit. Submissions are accepted via the Proceedings Track (published in PMLR) or the Recent Spotlight Track (no archival proceedings).
