FrozenLake PPO pilot

Base model: Qwen/Qwen2.5-0.5B-Instruct. Environment: 4x4 FrozenLake, p=0.8 safe-tile probability, no slipping, grid and coordinates. PPO/GAE, no rollout filtering. Training: 4 map groups x 8 trajectories, up to 100 updates, 5 turns, at most 2 actions per turn, response limit 128 tokens. Actor LR 1e-6, critic LR 1e-5, entropy coefficient 0.001. See results/config.yaml for all settings. Validation: fixed 64 seeds (123 through 186), greedy decoding, before training and every 10 steps. Training maps start at seed 10000. One training run only.

W&B: https://wandb.ai/xiaoyiwang2027-northwestern-university/ragen_pilot_frozenlake/runs/8baf50af33eb

Training exit code: 0 Latest logged step: 100 Best saved TRAINED checkpoint by validation success, then reward: step_0030

Each completed HF checkpoint is under checkpoints/step_NNNN/. After training/upload finishes, the selected trained checkpoint is copied to the repository root for normal from_pretrained loading. Check UPLOAD_COMPLETE.json before assuming the root model upload is complete. This is selection on the validation set, NOT a held-out test result. Step 0 is the untrained baseline; the trained checkpoint need not outperform it.

Sankalp Thakur

Compact learned predictors and controllers for industrial setpoint control, tested against tuned PI and MPC on simulated plants: a two-pump pressure manifold, the Johansson four-tank system, and a thermal CSTR. It includes a C99 predictor for edge devices. All plants are synthetic, and the methods are adaptations of published papers, not reproductions. The offline FKDPP adaptation underperformed PI. Every outcome, including the losses, is kept in the reports. - The saved predictor is 12,484 bytes, with fixed-size inference. - The decision time is about 0.61 ms at the 95th percentile on an Apple ARM host. That excludes communication, PLC scans and admission checks. - The C99 predictor…

DiscoDemo-Stage1_RL-FMB_Round-alpha0

DAVIAN Robotics

The data generator of DiscoDemo for the FMB-Round task (insert a cylindrical peg into its hole on the FMB board): a state-based reinforcement-learning policy trained in simulation — the P-RFCL baseline generator (α = 0: the same reverse-curriculum RL without the diversity reward). Rolling it out generates demonstrations such as those in the Stage2 dataset below. Only what is needed to roll the policy out is released; the critic and other training-only state are omitted. Loading requires the DiscoDemo training code: https://github.com/DAVIAN-Robotics/DiscoDemo.
