CatkinChen/nethack-ppo-ablation-baseline_no_intrinsic

This repository contains a complete Sequential Skill RL model trained on NetHack/MiniHack environments.

Model Components

1. PPO Policy (`ppo_policy.pth`)

Type: Proximal Policy Optimization agent
Environment: MiniHack-Room-Random-15x15-v0
Training Steps: 195
Features:
- Curiosity-driven exploration: False
- Random Network Distillation: False

2. VAE Model (`vae_model.pth`)

Type: Variational Autoencoder
Purpose: Encodes NetHack observations into latent skill representations
Latent Dimension: 96
Architecture: Unknown

3. HMM Model (`hmm_model.pth`)

Type: Hidden Markov Model (Sticky HDP-HMM)
Purpose: Models sequential skill transitions and dynamics
Integration: Used for intrinsic reward computation

Usage

python

import torch
from training.online_rl import train_online_ppo_with_pretrained_models

# Load the complete model
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')

# Load individual components
ppo_checkpoint = torch.load('ppo_policy.pth', map_location=device, weights_only=False)
vae_data = torch.load('vae_model.pth', map_location=device, weights_only=False)
hmm_data = torch.load('hmm_model.pth', map_location=device, weights_only=False)

# Use for inference or continued training
results = train_online_ppo_with_pretrained_models(
