Bidirectional Causal Language Model Optimization to Make GPT and Llama Robust Against the Reversal Curse

The Reversal Curse in Language Models Large language models (LLMs) are advanced AI systems, but they often have trouble understanding relationships between different entities. This issue is known as the "Reversal Curse." **What is the Reversal Curse?** The Reversal Curse happens when LLMs struggle with relationships that can be reversed. For example, they can easily answer "Who is the mother of Tom Cruise?" but may have difficulty with "Who is Mary Lee Pfeiffer’s son?" This shows that LLMs have gaps in understanding how relationships work. **Research Findings** Researchers from Renmin University of China studied the Reversal Curse and found that the way LLMs are trained contributes to this problem. **How LLMs are Trained** LLMs are usually trained using a method called next-token prediction (NTP). This method focuses only on the previous words, which limits the model's ability to understand reversed relationships. This is why they struggle with certain questions. **Improving with General Language Models (GLMs)** General Language Models (GLMs) use a different training method that helps them understand both previous and following words better. This makes GLMs more effective at handling the Reversal Curse. For example, GLMs achieved about 80% accuracy in a task involving names and descriptions, while LLMs like Llama scored 0%. **Proposed Solutions** Researchers suggest changing how LLMs are trained to be more like GLMs. They introduced a new training method called Bidirectional Causal Language Model Optimization (BICO). This method improves accuracy in tasks like reverse translation and math problems by using bidirectional attention and rotary position embeddings. **Conclusion and Future Directions** The study highlights the Reversal Curse and offers a strategy to overcome it. By using a causal language model with a new training objective, researchers are paving the way for advanced techniques like Reinforcement Learning from Human Feedback (RLHF). **Get Involved** Stay connected for more insights and updates.
