+### Group-wise Entropy Equalization (GEE)
+
+GEE balances sensitive groups by:
+- Group mass parity (push group probability mass toward target pi)
+- Group entropy equalization (normalize and equalize per-group entropy)
+- Optional anchors to keep global token-entropy and sensitive-union mass close to baseline
+
+Default groups file: `groups/gender.json`.
+
+Run on Colab (example):
+
+```bash
+!python train.py \
+  --model_name Qwen2.5-1.5B \
+  --model_path Qwen/Qwen2.5-1.5B \
+  --train_data dataset/1shot_rlvr/pi1_r1280.parquet \
+  --effective_batch 4 --micro_batch_size 1 \
+  --temperature 0.5 --learning_rate 2e-5 --sample_temp 0.5 \
+  --max_steps 15 --log_steps 1 --save_steps 5 \
+  --run_name colab_gee15 --wandb_project one-shot-em \
+  --no_deepspeed --mixed_precision no \
+  --gee_enable --gee_groups_path groups/gender.json \
+  --gee_alpha 1.0 --gee_beta 0.3 --gee_lambda 0.0 --gee_gamma 0.0 --gee_tau 1e-3 --gee_top_m 50
+```
+
+You can customize groups and target proportions in the JSON.
