LatentGym_Qwen3-8B_10episodes_4Envs_LOO_secretary Overview

This model is an 8 billion parameter variant of the Qwen3 architecture, developed by namkoong-lab. It has been fine-tuned using the GRPO (Generalized Reinforcement Learning with Policy Optimization) algorithm, specifically for in-context meta-learning within the LatentGym testbed. The training focused on a "held-out-secretary" setup, utilizing 3 training environments over 10 episodes.

Key Capabilities & Training Focus

The model's training regimen emphasizes meta-learning across various latent conditions, enabling it to adapt to new tasks based on in-context examples. The training involved specific latent features for different environments:

  • Hangman: vowel_count_4, ending_ABLE
  • Wordladder: hub_word_3letter, hub_word_4letter, order_outside_in
  • Number Guessing: set_of_3, range_100

Training hyperparameters included an AdamW optimizer with a learning rate of 5e-07, a constant learning rate schedule with warmup, and a KL coefficient \u03b2 of 0.04. The model was trained for 20 epochs with a max generation length of 64 tokens, using a seed of 263.

Good For

  • In-context meta-learning research: Particularly for understanding how LLMs adapt to new tasks with limited examples.
  • LatentGym testbed experiments: As a component within the LatentGym collection for evaluating meta-learning performance.
  • Adaptive problem-solving: In environments similar to hangman, wordladder, or number guessing, where the model needs to infer rules or strategies from context.
