Coupled Usage-Sense Processes: Temporal and Attributable Lexical Semantic Change
Haruka Ezoe, Ryohei Hisano
Lexical semantic change is usually summarized by a scalar distance between independently sampled period distributions. This measures how much a word changed, but does not reveal wh…
Multiscale Euclidean Network Trajectories: Second-Moment Geometry, Attribution, and Change Points
Haruka Ezoe, Ryohei Hisano
Understanding a dynamic network requires more than locating when it changes: we also want to know the magnitude and structural direction of change and which nodes contribute. Unfol…
Unfolded Laplacian Spectral Embedding: A Theoretically Grounded Approach to Dynamic Network Representation
Haruka Ezoe, Hiroki Matsumoto, Ryohei Hisano
Dynamic relational data arise in many machine learning applications, yet their evolving structure poses challenges for learning representations that remain consistent and interpret…
Model Compression Method for S4 with Diagonal State Space Layers using Balanced Truncation
Haruka Ezoe, Kazuhiro Sato
To implement deep learning models on edge devices, model compression methods have been widely recognized as useful. However, it remains unclear which model compression methods are…
