PolySim: Deterministic Polynomial Surrogates for Cross-Modal Retrieval on CiM

Xinzhao Li, Charles Power, Pengyu Ren, Jongun Won, Likai Pei, Yuting Hu, et al.

Cross-modal retrieval on edge devices benefits from probabilistic embeddings that capture semantic uncertainty, but deploying them on compute-in-memory (CiM) hardware remains an open problem. The core difficulty is a sampling gap: probabilistic methods such as PCME rely on Monte…

CHILDES-Aligned: A Curated Children's Speech Dataset via Multi-Model Timestamp Ensembling

Haolong Zheng, Yuanzhuo Hu, Xinyu Liang, Vishal Sunder, Dancheng Liu, Jinjun Xiong, et al.

CHILDES is a large-scale child speech corpus containing long-form recordings of naturalistic child-adult interactions, making it a valuable resource for studying child speech and language development. However, utterance-level timestamps provided in this corpus are often noisy, in…
