From 09d50e47860da0035e178a442dc936028808a0b3 Mon Sep 17 00:00:00 2001 From: YurenHao0426 Date: Mon, 16 Feb 2026 14:44:42 -0600 Subject: Add memory centering, grid search experiments, and energy visualizations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add centering support to MemoryBank (center_query, apply_centering, mean persistence in save/load) to remove centroid attractor in Hopfield dynamics - Add center flag to MemoryBankConfig, device field to PipelineConfig - Grid search scripts: initial (β≤8), residual, high-β, and centered grids with dedup-based LLM caching (89-91% call savings) - Energy landscape visualization: 2D contour, 1D profile, UMAP, PCA heatmap comparing centered vs uncentered dynamics - Experiment log (note.md) documenting 4 rounds of results and root cause analysis of centroid attractor problem - Key finding: β_critical ≈ 37.6 for centered memory; best configs beat FAISS baseline by +3-4% F1 Co-Authored-By: Claude Opus 4.6 --- figures/fig1_contour.png | Bin 0 -> 1543206 bytes 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 figures/fig1_contour.png (limited to 'figures/fig1_contour.png') diff --git a/figures/fig1_contour.png b/figures/fig1_contour.png new file mode 100644 index 0000000..87aca0b Binary files /dev/null and b/figures/fig1_contour.png differ -- cgit v1.2.3
