May 1, 2026

May 2026 monthly summary for dice-group/dice-embeddings: Delivered deployment governance improvements for GitHub Pages and addressed deployment gating issues. Implemented GitHub Pages deployment gating to push events only and added contents:write permission in the CI workflow. This reduces the risk of unintended public page updates while maintaining content updates for legitimate pushes. Commit reference: f0c111dadf40d7590aa64b6039168a7d3cca02f6.

Feb 1, 2026

February 2026 (dice-group/dice-embeddings) — Key features delivered, major fixes, and business impact. Key features delivered: - FixedNegSample: deterministic negative sampling, dataset support, and seed-based reproducibility across training runs; added regression tests and guidance for multi-GPU usage. - KeciTransformer: introduced transformer-based model for Clifford algebra embeddings with enhanced embedding construction. - Training workflow improvements: added --path_to_store_single_run for clearer data management and training commands. Major bugs fixed: - KeciTransformer input dimension divisibility bug: automatically determine the largest valid divisor to ensure proper operation when input_dim is not divisible by n_head, preventing AssertionError in TransformerSelfAttention. Overall impact and accomplishments: - Improved reproducibility, debuggability, and operational reliability for embeddings training; groundwork for scalable multi-GPU workflows; clearer training configurations reduce operational overhead. Technologies/skills demonstrated: - PyTorch transformer architectures, dataset design, deterministic sampling and regression testing, multi-GPU readiness, and training command-line tooling.
