Decoupling the "What" and "Where" With Polar Coordinate Positional Embeddings

Researchers present Polar Coordinate Position Embeddings (PoPE), an improvement to RoPE rotary position embeddings that decouples content matching from positional matching in Transformer attention mechanisms. PoPE demonstrates superior performance on language modeling, music, and genomic sequence tasks while achieving strong zero-shot length extrapolation capabilities without additional fine-tuning.

Retrievit: In-context Retrieval Capabilities of Transformers, State Space Models, and Hybrid Architectures

Research compares Transformers, State Space Models (SSMs), and hybrid architectures for in-context retrieval tasks, finding hybrid models excel at information-dense retrieval while Transformers remain superior for position-based tasks. SSM-based models develop unique locality-aware embeddings that create interpretable positional structures, explaining their specific strengths and limitations.
