手写单字体的识别,在看过卷积神经网络的mnist例子之后,很容易实现,那么如何实现多字体的同时识别呢? 如下图 LeCun大神所用的是SDNN space displacement neural network,这是什么鬼? 经过一番查询之后,原来它就是滑动窗口+图像金子塔+NMS,2015年yahoo的一篇论文 Multi-view Face Detection using deep convolutional Neural Networks 用的也是这种方法 参考页面:https://www…
0.引言 我们发现传统的(如前向网络等)非循环的NN都是假设样本之间无依赖关系(至少时间和顺序上是无依赖关系),而许多学习任务却都涉及到处理序列数据,如image captioning,speech synthesis,music generation是基于模型输出序列数据:如time series prediction,video analysis,musical information retrieval是基于模型输入需要序列数据:而如translating natural language…

Modern neuroscientists often discuss the brain as a type of computer. Neural networks aim to do the opposite: build a computer that functions like a brain. Of course, we only have a cursory understanding of the brain’s complex functions, but by creat…
