Cyclic Contrastive Knowledge Transfer for Open-Vocabulary Object Detection

ICLR 2025poster

In pursuit of detecting unstinted objects that extend beyond predefined categories, prior arts of open-vocabulary object detection (OVD) typically resort to pretrained vision-language models (VLMs) for base-to-novel category generalization. However, to mitigate the misalignment between upstream imag…

LLM-FP4: 4-Bit Floating-Point Quantized Transformers

EMNLP 2023long main

We propose LLM-FP4 for quantizing both weights and activations in large language models (LLMs) down to 4-bit floating-point values, in a post-training manner. Existing post-training quantization (PTQ) solutions are primarily integer-based and struggle with bit widths below 8 bits. Compared to intege…
