A simple DNN regression for the chemical composition in essential oil
[ "cs.LG" ]
Although experimental design and methodological surveys for mono-molecular activity/property has been extensively investigated, those for chemical composition have received little attention, with the exception of a few prior studies. In this study, we configured three simple DNN regressors to predict essential oil prop...

A Conceptual Model of Intelligent Multimedia Data Rendered using Flying Light Specks
[ "cs.DB", "cs.ET", "cs.MM" ]
A Flying Light Speck, FLS, is a miniature sized drone configured with light sources to illuminate 3D multimedia objects in a fixed volume, an FLS display. A swarm of FLSs may provide haptic interactions by exerting force back at a user's touch. This paper presents a conceptual model for the multimedia data to enable co...

Improving Fine-grained Visual Understanding in VLMs through Text-Only Training
[ "cs.CL" ]
Visual-Language Models (VLMs) have become a powerful tool for bridging the gap between visual and linguistic understanding. However, the conventional learning approaches for VLMs often suffer from limitations, such as the high resource requirements of collecting and training image-text paired data. Recent research has ...
