LLM-Oriented Retrieval Tuner

no code implementations4 Mar 2024 Si Sun, Hanqing Zhang, Zhiyuan Liu, Jie Bao, Dawei Song

Dense Retrieval (DR) is now considered as a promising tool to enhance the memorization capacity of Large Language Models (LLM) such as GPT3 and GPT-4 by incorporating external memories.

A Survey of Controllable Text Generation using Transformer-based Pre-trained Language Models

no code implementations14 Jan 2022 Hanqing Zhang, Haolin Song, Shaoyu Li, Ming Zhou, Dawei Song

In recent years, methods using large-scale pre-trained language models (PLMs), in particular the widely used transformer-based PLMs, have become a new paradigm of NLG, allowing generation of more diverse and fluent text.

Mengzi: Towards Lightweight yet Ingenious Pre-trained Models for Chinese

1 code implementation13 Oct 2021 Zhuosheng Zhang, Hanqing Zhang, Keming Chen, Yuhang Guo, Jingyun Hua, Yulong Wang, Ming Zhou

Although pre-trained models (PLMs) have achieved remarkable improvements in a wide range of NLP tasks, they are expensive in terms of time and resources.

ToxTrac: a fast and robust software for tracking organisms

no code implementations8 Jun 2017 Alvaro Rodriquez, Hanqing Zhang, Jonatan Klaminder, Tomas Brodin, Patrik L. Andersson, Magnus Andersson

The main advantages of ToxTrac are: i) no specific knowledge of the geometry of the tracked bodies is needed; ii) processing speed, ToxTrac can operate at a rate >25 frames per second in HD videos using modern desktop computers; iii) simultaneous tracking of multiple organisms in multiple arenas; iv) integrated distortion correction and camera calibration; v) robust against false positives; vi) preservation of individual identification if crossing occurs; vii) useful statistics and heat maps in real scale are exported in: image, text and excel formats.

UmUTracker: A versatile MATLAB program for automated particle tracking of 2D light microscopy or 3D digital holography data

no code implementations27 Jan 2017 Hanqing Zhang, Tim Stangner, Krister Wiklund, Alvaro Rodriguez, Magnus Andersson

We present a versatile and fast MATLAB program (UmUTracker) that automatically detects and tracks particles by analyzing video sequences acquired by either light microscopy or digital in-line holographic microscopy.

Circle detection using isosceles triangles sampling

no code implementations2 Nov 2015 Hanqing Zhang, Krister Wiklund, Magnus Andersson

Extensive experiments using both synthetic and real images were presented and results were compared to leading state-of-the-art algorithms and showed that the proposed algorithm: are efficient in finding circles with a low number of iterations; has high rejection rate of false-positive circle candidates; and has high robustness against noise, making it adaptive and useful in many vision applications.
