Summarize the recent development of CNN Model (i) from:https://zhuanlan.zhihu.com/p/30746099 Yu June computer vision and deep learning1. PrefaceLong time no update column, recently because of the project to contact the Pytorch, feeling opened the deep learning new world of the door. In his spare time, Pytorch trained the recent CNN model of State-of-the-art in image classification, which is summarized in the article as follows: ResNet [1, 2]

OpenGL's top rookie question read a book "OpenGL three-dimensional graphics system development and application Technology", however, the function involved in the Glut.h file is not properly connected, the typical error is as follows:------started build: Project: Gears, Configuration: Debug Win32-- ----1> is being linked ... 1>gears.obj:error LNK2019: unresolved external symbol ___glutinitwithexit@

there, the creation of new.After the disassembly of the build method, there is no new thing in the loop, there is only one StringBuilder object.After this analysis, it is obvious that Stringbuider is working on the string is more efficient resource-intensive, if it is simply a few string merges, it can use +.This example uses the disassembly to look a lot simpler, in fact, some comparisons are through time calculation, of course, is also possible.StringBuilder is introduced in the SE5 version,
