Improved Zero-Shot Classification by Adapting VLMs with Text Descriptions

1 code implementation4 Jan 2024 Oindrila Saha, Grant van Horn, Subhransu Maji

By prompting LLMs in various ways, we generate descriptions that capture visual appearance, habitat, and geographic regions and pair them with existing attributes such as the taxonomic structure of the categories.

PARTICLE: Part Discovery and Contrastive Learning for Fine-grained Recognition

1 code implementation25 Sep 2023 Oindrila Saha, Subhransu Maji

For example, under a linear-evaluation scheme, the classification accuracy of a ResNet50 trained on ImageNet using DetCon, a self-supervised learning approach, improves from 35. 4% to 42. 0% on the Caltech-UCSD Birds, from 35. 5% to 44. 1% on the FGVC Aircraft, and from 29. 7% to 37. 4% on the Stanford Cars.
