Summary

RIKEN AIP's Computational Learning Theory Team hosts two research talks from Telefonica researchers visiting from Spain. Dr. Dimitra Tsigkari presents "Network Optimization for Split Learning," covering optimization challenges in Split Learning frameworks where heterogeneous clients offload part of model training to a server, with results drawn from INFOCOM 2024/2026 and AAAI 2026 papers (including work on catastrophic forgetting under data heterogeneity). Dr. Fion Mc Inerney follows with "Non-Clashing Teaching in Graphs," a talk on batch machine teaching theory. The work studies the teaching dimension for balls in graphs, presenting NP-hardness, W[1]-hardness, FPT algorithms, and combinatorial results for trees, cycles, and interval graphs, drawing from COLT 2024, ICLR 2025, and ICLR 2026 papers. Each talk runs 45 minutes including Q&A. The seminar is delivered via Zoom for all registered participants, with on-site attendance at the RIKEN Nihonbashi Office Open Space restricted to RIKEN members.
