An Offline Architecture for Assessment-Driven Remediation Videos

An Offline Architecture for Assessment-Driven Remediation Videos

We design an offline generative AI pipeline that turns course materials and assessment evidence into reusable, personalised remediation videos.

EgoBlind-RA: Towards Safer Egocentric Assistive AI for Blind Users via Risk-Adaptive Routing

EgoBlind-RA: Towards Safer Egocentric Assistive AI for Blind Users via Risk-Adaptive Routing

EgoBlind-RA routes egocentric queries from blind and low-vision users by urgency using a lightweight CLIP classifier (0.905 ROC-AUC), then allocates response policies matched to their safety stakes — showing that the value of DPO and the cost of routing noise both depend sharply on architectural regime.

Applying Contrastive Learning to Stellar Spectra

We present StarCLIP, a contrastive learning framework aligning APOGEE and JWST/NIRSpec spectra into a unified latent space, enabling accurate stellar property recovery and demonstrating the feasibility of foundation models for future spectroscopic surveys.

Pulsating Red Giants in a Globular Cluster: omega Centauri

Pulsating Red Giants in a Globular Cluster: omega Centauri

We analyzed light curves of 16 PRGs in omega Centauri, confirming the prevalence of LSPs and establishing period–luminosity sequences consistent with Population II red giants elsewhere.
