Conference on Parsimony and Learning (CPAL)
March 2027, Tokyo

Subject Areas

CPAL 2027 welcomes contributions in which a clear parsimony principle is central. The following list is illustrative rather than exhaustive.

Theory and Foundations

  • Sparsity, structured sparsity, low rank, subspaces, manifolds, tensors, graphs, latent-variable models, and other low-dimensional structures.
  • Statistical and computational foundations of representation and feature learning.
  • Identifiability, generalization, robustness, implicit bias, and statistical–computational tradeoffs.
  • Symmetry, invariance, equivariance, causality, modularity, and compositional structure.
  • Information-theoretic, minimum-description-length, and compression-based views of learning.
  • Theoretical neuroscience, cognitive science, and biologically inspired mechanisms for parsimonious learning.

Methods and Models

  • Sparse coding, dictionary learning, matrix and tensor methods, inverse problems, and structured recovery.
  • Optimization and feature-learning dynamics that discover or induce parsimonious structure.
  • Interpretable and structured neural architectures, including algorithm unrolling.
  • Pruning, quantization, distillation, low-rank adaptation, modular networks, mixtures of experts, and conditional computation.
  • Data-, parameter-, memory-, energy-, and compute-efficient training and inference.
  • Parsimonious foundation, generative, multimodal, federated, continual, and agentic learning.

Systems, Data, and Applications

  • Hardware–algorithm and software–system co-design for structured or sparse computation.
  • Benchmarks, datasets, and metrics that reveal or evaluate parsimony and accuracy–efficiency tradeoffs.
  • Parsimonious learning for perception, action, reasoning, robotics, and control.
  • Scientific machine learning, signal and image processing, neuroscience, biology, medicine, engineering, and social science.
  • Resource-constrained, distributed, networked, and real-world intelligent systems.

Submissions proposing a new notion of parsimony are especially welcome when the connection is clearly motivated. Authors who are uncertain about fit may contact the Program Chairs at pcs@cpal.cc.
