# E2AM Ablation Results: ResNet-50

Energy-aware training ablation study for **ResNet-50** across three image-classification datasets: **CIFAR-10**, **CIFAR-100**, and **Tiny-ImageNet**.

Each dataset has 15 training variants (8 individual-method M0..M7, 7 cumulative ablation C0..C6) at 50 epochs, plus a 5-variant deployment pipeline (FP32 baseline, structured pruning, pruning+finetune, INT8 quantization, pruned+INT8).

**Status**: 45 completed variants, 0 partial.

## Deployment results

See `paper_tables/deployment_results_table.csv`.

## Methodology

**Model**: ResNet-50 (~23.5M params).

**Training protocol**: from scratch, SGD with momentum 0.9, weight decay 5e-4, initial LR 0.1, 50 epochs, 1 warmup epoch. All variants share the same protocol so ablation comparison stays apples-to-apples across the matrix.

**Input**: native dataset resolution upsampled to 32x32 in-model via `nn.Upsample` (FX-traceable to keep D3/D4 INT8 quantization possible).

**Optimization toggles** (the 5 individual methods and their cumulative combinations):

| Method | Mechanism |
|---|---|
| Tensor cache | Training images held in RAM as a normalized float tensor |
| AMP | torch.cuda.amp.autocast + GradScaler |
| Grad accum (x2) | Accumulate gradients across 2 mini-batches |
| L1 sparsity | Lambda * sum(|w_i|) added to loss with lambda=1e-8 |
| Cosine LR | lr(t) = lr_max * 0.5 * (1 + cos(pi*t/T)) |
| EAG early-stop | Energy-Aware Gain: stop when accuracy gain per joule plateaus |

**Energy measurement**: GPU power sampled at 1 Hz via `nvidia-smi --query-gpu=power.draw`. Energy = trapezoidal integration over power-vs-time. CO₂ = energy_kWh * 0.475 (global average grid intensity).

**Hardware**: Single NVIDIA T4 (14.5 GB) on Kaggle.

```

## Reproducibility

Each variant directory has a `config.yaml` with the exact configuration used. To reproduce:

1. `huggingface-cli download Shanmuk4622/E2AM_ResNet50 --repo-type dataset`
2. Load the `e2am.py` library and call the appropriate config factory
3. Run `e2am.train_one_run(cfg)`

## Limitations

- Energy measurement is GPU-only (via nvidia-smi); CPU/memory power not included
- Pruning is mask-based; no wall-clock speedup without sparsity-aware runtime
- INT8 (D3/D4) is CPU FX static quantization (fbgemm); may fail on transformer blocks. Failures logged in metrics.json rather than crashing.
- Single-T4 reproduction; multi-GPU not validated
- SGD@0.1 is suboptimal for some architectures; the paper compares variant-to-variant deltas which remain meaningful regardless
