It's Not RoPE that Creates Sinks: The Role of Self-Concentration and Value-Non-Mixing in Attention
Raito Kiya, Satoki Ohashi, Kosuke Sato +6
Large Language Models (LLMs) often exhibit "Attention Sink" (AS) and the accompanying "Massive Activations" (MAs) at the initial position of a sequence. These phenomena frequently…
Language Models Compare Quantities Using Number-specific and Unit-specific Heuristics
Mutsumi Sasaki, Go kamoda, Ryosuke Takahashi +4
Quantities with measurement units, such as 110 cm and 1.2 m, require language models (LMs) to combine a numeral with a symbolic unit scale. Here, we study how LMs compare such quan…
Can Language Models Handle a Non-Gregorian Calendar? The Case of the Japanese wareki
Mutsumi Sasaki, Go Kamoda, Ryosuke Takahashi +4
Temporal reasoning and knowledge are essential capabilities for language models (LMs). While much prior work has analyzed and improved temporal reasoning in LMs, most studies have…
TopK Language Models
Ryosuke Takahashi, Tatsuro Inaba, Kentaro Inui +1
Sparse autoencoders (SAEs) have become an important tool for analyzing and interpreting the activation space of transformer-based language models (LMs). However, SAEs suffer severa…
The Curse of Popularity: Popular Entities have Catastrophic Side Effects when Deleting Knowledge from Language Models
Ryosuke Takahashi, Go Kamoda, Benjamin Heinzerling +2
Language models (LMs) encode world knowledge in their internal parameters through training. However, LMs may learn personal and confidential information from the training data, lea…
