LDA-CRF:一种基于概率图模型的目标检测方法
... ;目标检测和识别是计算机视觉和机器学习的研究热点.近年来,主题模型(如LDA等)在无监督的图像识别和定位等应用中获得了巨大的成功.然而,LDA忽略了图像区域之间的空间关系,并且不能处理连续值的视觉特征 ... 向量.而条件随机场(CRF)能够利用图像区域之间的局部相关性来提高分类准确性.基于LDA和CRF提出了一种LDA-CRF模型.通过利用LDA生成的 ... 信息来辅助CRF的分类,同时结合图像区域之间结构化的类别信息来改进LDA的主题生成机制.实验结果表明,LDA-CRF模型的检测效果要优于 ...

lda-cython
Topic Model or LDA in Cython
This is a cython implementation of LDA.
The code is a direct adaptation from Mathieu Blonedl's implmentation.
See http://www.mblondel.org/journal/2010/08/21/latent-dirichlet-allocation-in-python/
With Cython, we can obtain a ...
