Why It Matters: First-Explore avoids catastrophic failures in meta-RL, enabling strategic exploration and unlocking new potential for adaptive AI in robotics, resource optimization, and high-stakes decision-making. 5/5

Results That Speak: 🔥 In challenging domains:
Achieves 2–10x higher cumulative reward across bandits, dark treasure rooms, and ray mazes.
Succeeds where existing methods fail to explore effectively or exploit consistently. 4/5

The Idea: ✨ First-Explore addresses this by:
1. Training separate policies for exploration (gather info) and exploitation (maximize rewards).
2. Combining them after training to achieve high cumulative rewards. 3/5

Why Prior Methods Fail: Methods like RL² and VariBAD fall into a trap:
🔄 Poor early exploitation → exploration seems bad → agent learns to avoid exploration! → No further learning.
Even simple tasks like bandits can cause failure. 2/5

The Problem: How can RL agents adapt quickly to new scenarios, while performing well as they adapt?
💡 Standard RL is slow, needing millions of trials.
Meta-RL aims to fix this but fails when exploration demands early sacrifices, limiting performance! 1/5
