本文是对CRF基本原理的一个简明的介绍。当然,“简明”是相对而言中,要想真的弄清楚CRF,免不了要提及一些公式,如果只关心调用的读者,可以直接移到文末。 图示 # 按照之前的思路,我们依旧来对比一下普通的逐帧softmax和CRF的异同。 逐帧softmax # CRF主要用于序列标注问题,可以简单 阅读全文

背景 之前在研究Object Detection的时候,只是知道Precision这个指标,但是mAP(mean Average Precision)具体是如何计算的,暂时还不知道。最近做OD的任务迫在眉睫,所以仔细的研究了一下mAP的计算。其实说实话,mAP的计算,本身有很多现成的代码可供调用了, 阅读全文
