training data, and proves that there is a large disturbance in the final output layer caused by the disturbance of small input space . This method is similar to the difficult-to-mistake sample mining (hard-negative mining), that is, the collection of classifier error large samples, so that the input distribution of further iterations to focus on the distribution of these difficult samples. By minimizing the distortion function d, such as the following formula, to obtain adversarial

As the company needs, its own modified offline map API. The package has the following features:1. Support the use of Google Maps tiles (not recommended, inefficient, high zoom level when dragging some lag, it is recommended to comment on the code block: Overlaytilelayer.gettilesurl, using Google to Baidu's jar conversion code.2. Include pull-frame amplification, ranging, line drawing, printing and other functions (modified tool source code, support right-click Cancel amplification, ranging gestu

This article mainly introduces the basic network programming examples in Lua, including simple server building and related Web Component introduction, and so on, need friends can refer to the following LUA is a highly flexible language that is often used in multiple platforms, including Web applications. The 2004-year Kepler community provides the LUA Web Component open source. While there are other web f

Recently, the author in the school network maintenance process encountered two examples are not common network fault, but very interesting, feel the need to take them out for everyone's reference. First failure: Client does not automatically obtain its TCP/IP configuration from the DHCP server immediately Our school's IP addresses, DNS, and gateways are automat

error messages, This is related to whether the kernel is sending ICMP messages back to the UDP socket interface. I did the experiment under Ubuntu and found that this ICMP message was not returned.Attention:If you call the Connect function in a TCP program, the server side does not run the program, and connect returns an error directly (because three handshakes are established at this time), but no error is returned in UDP. several issues to be aware of:1. In general, we do not specify the IP a
