Hierarchical Semantic RL: Tackling the Problem of Dynamic Action Space for RL-based Recommendations
Recommender Systems (RS) are fundamental to modern online services. While most existing approaches optimize for short-term engagement, recent work has begun to explore reinforcement learning (RL) to model long-term user value. However, these efforts face significant challenges due to the vast, dynamic action spaces inherent in recommendation, which hinder stable policy learning. To resolve this bottleneck, we introduce Hierarchical Semantic RL (HSRL), which reframes RL-based recommendation over…

JWST Observations of SN 2024ggi II: NIRSpec Spectroscopy and CO Modeling at 285 and 385 Days Past the Explosion
We present James Webb Space Telescope (JWST) NIRSpec 1.7--5.5 micron observations of SN~2024ggi at +285.51 and +385.27 days post-explosion. The late-time nebular spectra are dominated by emission lines from various ionization states of H, Ca, Ar, C, Mg, Ni, Co, and Fe. We also detect strong CO emission in both the first overtone and fundamental vibrational bands. Most atomic features exhibit asymmetric line profiles, indicating an aspherical explosion. Using observed fluxes combined with non-LT…

Day 4: Adiba Jaigirdar
Thought I'd mix things up a bit in terms of intensity & genre. Jaigirdar has written several lovely sapphic teen romances that grapple with parental acceptance in Muslim Bengali immigrant culture, along with racism and other aspects of second generation immigrant life in Dublin.
I've discovered a few other Southeast Asian authors at my local library who will appear on this list, but I'm putting Jaigirdar first because of just how enjoyable her books are, and because I generally find queer romance to be more engaging than non-queer romance. Jaigirdar's characters are sympathetic and convincing, and their problems are both dramatic and a little funny. "Hani & Ishu's Guide to Fake Dating" is probably my favorite by Jaigirdar, but I also enjoyed "The Henna Wars" and "Rani Choudhury Must Die." "A Million to One" is a bit of a departure from her other books, as historical fiction with a heist plot, but it still engages with Irish culture, immigrants, and queer romance.

SynParaSpeech: Automated Synthesis of Paralinguistic Datasets for Speech Generation and Understanding
Paralinguistic sounds, like laughter and sighs, are crucial for synthesizing more realistic and engaging speech. However, existing methods typically depend on proprietary datasets, while publicly available resources often suffer from incomplete speech, inaccurate or missing timestamps, and limited real-world relevance. To address these problems, we propose an automated framework for generating large-scale paralinguistic data and apply it to construct the SynParaSpeech dataset. The dataset compr…

Variational data assimilation for the wave equation in heterogeneous media: Numerical investigation of stability
In recent years, several numerical methods for solving the unique continuation problem for the wave equation in a homogeneous medium with given data on the lateral boundary of the space-time cylinder have been proposed. This problem enjoys Lipschitz stability if the geometric control condition is fulfilled, which allows devising optimally convergent numerical methods. In this article, we investigate whether these results carry over to the case in which the medium exhibits a jump discontinuity. …
