Output-affecting algorithm changes (009eff7 → 084b65c) + +#### A1) Task MI / Synergy estimation changed (fix pseudo-replication) + +- **Old behaviour (009eff7)**: when `activation_samples="flatten_spatial"`, the target \(T\) (logit margin) is + repeated across spatial positions and treated as if it had \(B \times H \times W\) independent samples. Both + `MI(T;Y_i)` and the Gaussian synergy approximation were computed from these *spatially-flattened* stats: + - `mi_t` computed from `cov_ty / sqrt(var_t * var_y)` + - partner ordering for synergy used the *local* redundancy MI matrix (`mi_matrix`) from `cov_yy` + - joint MI `I(T; [Y_i, Y_j])` used `var_t, var_y, cov_ty, cov_yy` (local accumulator) + +- **New behaviour (084b65c)**: decision-level quantities involving image-level targets are computed from + **per-image pooled** activations (GAP), regardless of spatial sampling mode, to avoid pseudo-replication: + - `mi_t` computed from `cov_ty_task / sqrt(var_t_task * var_y_task)` + - partner ordering for synergy uses `mi_matrix_task` from the **task** covariance `cov_yy_task` + - joint MI uses task stats `var_t_task, var_y_task, cov_ty_task, cov_yy_task` + +This change can materially alter: +- within-layer cluster structure (esp. synergy dimension), +- halo significance tests (if enabled), +- pruning scores for any methods using synergy/red as components. + +#### A2) Cluster type mapping changed (reduce “label swapping” across layers) + +- **Old behaviour (009eff7)**: greedy assignment + 1) `critical := argmax(log_rq - red)` + 2) `redundant := argmax(red)` among remaining + 3) `synergistic := argmax(syn)` among remaining + 4) leftover is background + +- **New behaviour (084b65c)**: **global one-to-one assignment** over all permutations that maximizes a linear + score for the four semantic types (critical/redundant/synergistic/background). This is specifically intended + to reduce centroid/label “swaps” across layers that can make depth trends look noisy. + +This change is a likely contributor to the “cleaner critical-vs-depth trend” you observed in newer runs. + +#### A3) Pruning distribution changed (layer-level safety cap) + +- In `global_threshold` distributions, **per-layer sparsity is capped** (previously unbounded), preventing + pathological cases where a layer is completely removed (a common cause of collapse at high sparsity). + +This affects **all pruning methods**, not just cluster-aware ones, and can change both absolute performance and gaps. + +#### A4) Optional BN activation point support added + +New config knob: +- `activation_point`: `"pre_bn"` (default) vs `"post_bn"` (hook BN outputs). + +When using `"post_bn"`, the RQ denominator is adjusted by BN scale so RQ remains comparable. + +### B. Extra diagnostics added (primarily additive, but can affect RNG use) + +- **Metric ablation**: clustering can be run with metric subsets (`rq_red`, `rq_syn`, `red_syn`, …). +- **Halo permutation baseline**: compute null distributions by shuffling source-layer labels. + +These are usually *additive outputs*, but they can change runtime and (if any shared RNG is used) must be handled +carefully for strict reproducibility. + +### C. Reproducibility instrumentation added (post 084b65c) + +To make paper runs exactly reproducible from “current code”, we added: + +- **Deterministic calibration subset**: + - create a fixed set of `n_calibration` dataset indices using the experiment seed, + - save to `calibration_indices.json` in the run directory, + - compute metrics/Taylor/HRank on this deterministic subset via a calibration DataLoader (no shuffle). + +- **Run metadata**: + - write `run_metadata.json` to the run directory (git commit/dirty, python/torch/numpy versions, SLURM IDs), + - embed the same metadata into `results.json` under `metadata`. + +- **Configurable per-layer sparsity cap**: + - expose `max_per_layer_sparsity_cap` via `PruningPipelineOptions` and `PruningDistributionManager` kwargs. + - default remains `0.90` (current behaviour); set `1.0` to emulate legacy behaviour. + +### D. Paper protocol recommendation + +For the paper, we should: +- pick a **single** algorithm version (recommended: the newer task-level synergy + global type mapping), +- run **multi-seed** experiments and report mean ± std, +- generate all figures/tables from an explicit **manifest** of run directories (no mtime heuristics), +- record commit hashes + calibration indices in every run directory. +

-This note records **output-affecting** changes observed between the code version used for early “paper runs” -(`009eff7`) and a later version (`084b65c`), plus the reproducibility instrumentation added afterwards. - -### A. Output-affecting algorithm changes (009eff7 → 084b65c) - -#### A1) Task MI / Synergy estimation changed (fix pseudo-replication) - -- **Old behaviour (009eff7)**: when `activation_samples="flatten_spatial"`, the target \(T\) (logit margin) is - repeated across spatial positions and treated as if it had \(B \times H \times W\) independent samples. Both - `MI(T;Y_i)` and the Gaussian synergy approximation were computed from these *spatially-flattened* stats: - - `mi_t` computed from `cov_ty / sqrt(var_t * var_y)` - - partner ordering for synergy used the *local* redundancy MI matrix (`mi_matrix`) from `cov_yy` - - joint MI `I(T; [Y_i, Y_j])` used `var_t, var_y, cov_ty, cov_yy` (local accumulator) - -- **New behaviour (084b65c)**: decision-level quantities involving image-level targets are computed from - **per-image pooled** activations (GAP), regardless of spatial sampling mode, to avoid pseudo-replication: - - `mi_t` computed from `cov_ty_task / sqrt(var_t_task * var_y_task)` - - partner ordering for synergy uses `mi_matrix_task` from the **task** covariance `cov_yy_task` - - joint MI uses task stats `var_t_task, var_y_task, cov_ty_task, cov_yy_task` - -This change can materially alter: -- within-layer cluster structure (esp. synergy dimension), -- halo significance tests (if enabled), -- pruning scores for any methods using synergy/red as components. - -#### A2) Cluster type mapping changed (reduce “label swapping” across layers) - -- **Old behaviour (009eff7)**: greedy assignment - 1) `critical := argmax(log_rq - red)` - 2) `redundant := argmax(red)` among remaining - 3) `synergistic := argmax(syn)` among remaining - 4) leftover is background - -- **New behaviour (084b65c)**: **global one-to-one assignment** over all permutations that maximizes a linear - score for the four semantic types (critical/redundant/synergistic/background). This is specifically intended - to reduce centroid/label “swaps” across layers that can make depth trends look noisy. - -This change is a likely contributor to the “cleaner critical-vs-depth trend” you observed in newer runs. - -#### A3) Pruning distribution changed (global_threshold code path) - -**CRITICAL FIX (Jan 25, 2026)**: - -- **Old behaviour (009eff7, used for Jan 20 runs)**: For `distribution="global_threshold"`, the pipeline used - `MaskOperations.global_threshold_mask()` directly, which: - - Computes a single threshold across ALL layers - - Applies the threshold uniformly with NO per-layer caps - - Can prune entire layers if all their scores fall below threshold - -- **Changed behaviour (26d06b0, Jan 21)**: The direct `global_threshold_mask` call was REMOVED and replaced - with `PruningDistributionManager`, which: - - Computes the global threshold but then converts to per-layer amounts - - Applies `max_per_layer_sparsity_cap` (defaulted to 0.90) - - Produces different pruning distributions even with cap=1.0 - -- **Restored behaviour (current)**: The direct `global_threshold_mask` path is restored for - `distribution in {"global_threshold", "global"}`. This reproduces Jan 20 results exactly. - -**Impact**: This was the root cause of 4-7% accuracy drops at high sparsity (70%+) for cluster_aware_annealed -and 6% improvements for Taylor at 90%. The different distribution logic fundamentally changed which channels -were pruned at each sparsity level. - -#### A4) Optional BN activation point support added - -New config knob: -- `activation_point`: `"pre_bn"` (default) vs `"post_bn"` (hook BN outputs). - -When using `"post_bn"`, the RQ denominator is adjusted by BN scale so RQ remains comparable. - -### B. Extra diagnostics added (primarily additive, but can affect RNG use) - -- **Metric ablation**: clustering can be run with metric subsets (`rq_red`, `rq_syn`, `red_syn`, …). -- **Halo permutation baseline**: compute null distributions by shuffling source-layer labels. - -These are usually *additive outputs*, but they can change runtime and (if any shared RNG is used) must be handled -carefully for strict reproducibility. - -### C. Reproducibility instrumentation added (post 084b65c) - -To make paper runs exactly reproducible from “current code”, we added: - -- **Deterministic calibration subset**: - - create a fixed set of `n_calibration` dataset indices using the experiment seed, - - save to `calibration_indices.json` in the run directory, - - compute metrics/Taylor/HRank on this deterministic subset via a calibration DataLoader (no shuffle). - -- **Run metadata**: - - write `run_metadata.json` to the run directory (git commit/dirty, python/torch/numpy versions, SLURM IDs), - - embed the same metadata into `results.json` under `metadata`. - -- **Configurable per-layer sparsity cap**: - - expose `max_per_layer_sparsity_cap` via `PruningPipelineOptions` and `PruningDistributionManager` kwargs. - - default is `1.0` (disabled / legacy behavior); set e.g. `0.90` to enable a safety cap. - -### D. Isolation experiments (Jan 2026): quantifying each factor - -To understand which changes contributed to performance differences, we ran controlled isolation -experiments using the **exact Jan-20 checkpoint** but varying one config at a time: - -| Isolation Run | activation_point | task_activation_samples | type_mapping_mode | calibration_mode | cap | cluster_aware@0.9 | -|---------------|------------------|------------------------|-------------------|------------------|-----|-------------------| -| Jan-20 ref | pre_bn (implicit)| match (implicit) | greedy (implicit) | train_loader | 1.0 | **0.7866** | -| isoA | **post_bn** | gap | global | indices | 0.9 | 0.6262 | -| isoB | pre_bn | **gap** | global | indices | 0.9 | 0.7413 | -| isoC | pre_bn | match | **global** | indices | 0.9 | 0.7594 | -| isoD | pre_bn | match | **greedy** | indices | 0.9 | 0.7567 | -| isoE | pre_bn | match | greedy | indices | 1.0 | 0.7567 | -| isoF | pre_bn | match | greedy | **train_loader** | 1.0 | 0.7271 | -| isoG | pre_bn | match | global | **train_loader** | 1.0 | 0.7322 | - -**Key findings:** - -1. **activation_point is the dominant factor**: `post_bn` (isoA: 0.6262) is ~12% worse than `pre_bn` (0.74-0.76). - The old code always hooked Conv2d outputs directly (pre-BN), so `activation_point=pre_bn` is required - to match Jan-20 behaviour. - -2. **task_activation_samples matters**: Using `gap` (isoB: 0.7413) is ~1.8% worse than `match` (isoC: 0.7594). - The old code used spatially-flattened samples for all metrics including TaskMI/synergy, so - `task_activation_samples=match` is needed to reproduce. - -3. **type_mapping_mode has minimal effect**: `greedy` (isoD: 0.7567) vs `global` (isoC: 0.7594) differ by <0.3%. - -4. **calibration_mode affects results**: `indices` (deterministic) gives 0.75-0.76, while `train_loader` - (shuffled) gives 0.72-0.73. The variance from shuffle order is significant. - -5. **Remaining gap to Jan-20 (~2.7%)**: The best isolation run (isoC: 0.7594) still trails Jan-20 (0.7866) - by ~2.7%. This gap is attributed to **different calibration samples**: - - Jan-20 ran `do_train=true` (50 epochs), which advanced the torch RNG by ~50 `randperm(50000)` calls - - After training, the shuffled DataLoader produced a specific sequence of calibration samples - - Isolation runs used `do_train=false` (fresh RNG) or deterministic indices - - **Without the original RNG state, exact reproduction is impossible** - -### E. Recommendations for going forward - -1. **For new paper runs**: Use `activation_point=pre_bn` and `task_activation_samples=match` to match - the proven Jan-20 algorithm behaviour while benefiting from reproducibility improvements. - -2. **For reproducibility**: Always use `calibration_mode=indices` to get deterministic calibration subsets. - This trades off the exact Jan-20 samples for guaranteed reproducibility. - -3. **Accept ~2-3% variance**: Calibration sample selection introduces variance. Report mean ± std over - multiple seeds rather than relying on single-run numbers. - -4. **Run from scratch with saved indices**: For the best of both worlds, run `do_train=true` with - the new code (which saves calibration_indices.json) to get a fresh, fully reproducible baseline. - -### F. Paper protocol recommendation - -For the paper, we should: -- Use `activation_point=pre_bn` and `task_activation_samples=match` (matches Jan-20 algorithm) -- Use `calibration_mode=indices` (deterministic, reproducible) -- Run **multi-seed** experiments and report mean ± std -- Generate all figures/tables from an explicit **manifest** of run directories (no mtime heuristics) -- Record commit hashes + calibration indices in every run directory - -### G. MobileNet pruning regression diagnosis (Jan 25 2026) - -**Symptoms observed:** -- MobileNet pruning using `cluster_aware_annealed` dropped from ~59% (Jan 20-22 "good" runs) to ~10-55% - (Jan 23+ runs) at 50% sparsity -- Some methods crashed or returned near-random accuracy -- The 50% bar in the paper figure showed "Ours" significantly worse than Taylor for MobileNet - -**Root cause identified:** -Commit `967e9ae` (Jan 22 23:01 EST) introduced `max_per_layer_sparsity_cap = 0.90` as a **new default** -for `global_threshold` pruning distributions.

For MobileNet, this often targets depthwise layers or early pointwise layers, causing network collapse -3.
