recently want to study deep learning, from the beginning to see UFLDL (Unsuprisedfeature Learning and deep learning) tutorial, I put the answer to the after-class exercise here, as a note. Notes:1 : The self-coding algorithm is an unsupervised learning algorithm that learns hw,b (x) = x, so the last outputlayer inputlayer Span Style= "", the number of units is equal, while the middle hiddenlayer 0 PCA 2 : Visual self-encoder, the pro
Windows Media Encoder is an easy-to-use, powerful software that provides users with the ability to record their own images, recording from an image capture device or a desktop screen, and providing the ability to convert file formats. The main features are easy to use, high quality coding, enhanced programmable and management features: New user interface and wizards, easier to set up and make movies, to provide network live playback or demand playback
PHP original HTML encoder overflow problem solution. In PHP5.1.6, 4.4.4, and earlier versions, when searching for characters related to "htmlspecialchars () andhtmlentities, when the UTF-8 encoding is selected, it may trigger a PHP5.1.6, 4.4.4, or a previous version, while searching for characters related to "htmlspecialchars () and htmlentities, A possible buffer overflow may be triggered when the UTF-8 encoding is selected.

Please write a demo code. 2. I see an example of a pc6port led flashing code such as the following, do not know what it means? Is it a counter-operation? Why read a bit first?Gpio_writebit (GPIOC, Gpio_pin_6, (bitaction) (1-gpio_readoutputdatabit (GPIOC, Gpio_pin_6))); 3. Interrupt vector table is n
Incremental rotary encoder
Output the Pulse Sequence Based on the Rotation Variation of the axis. You can use other counters to calculate the number of output pulses and use the counters to check the rotation volume.
You can append a circuit to generate 2 times of a periodic signal, 4 times the number of pulses, and provide the resolution of current.

URL Decoder/Encoder
Not nearly as cool or flashy as the color blender, it's still useful for situations where a massively long Encoded URL needs to be decoded. I wrote this one for me, But figured I 'd throw it up here for anyone else who needed it.
This week, I made a computer mouse's encoder module and spent a whole week.This process makes us laugh and cry. We plan to use the CH3 and methane channels of tim3 to collect the PWM of the Left motor for speed measurement and ranging, and use the CH2 and cosine of tim4 to test the right motor.WriteCodeFirst, we did the left motor first. It went to Friday, and we found that the CH3 and 4th channels of the general timer could not be used for PWM input.
1, open the encoder, set the code frame parameters Profile@level, according to the needs of the direct choice of 720p or 1080p, etc. on the line.
2, the following encoding type (Encoding type) is more important. First is single, which is the simplest type of encoding, with the advantage of being fast, but with the same compression rate per frame, which can be wasteful or inadequate.
In general, this is enough, choose Single Pass mode, the followin
Record Cool
The settings in the Encoder window will directly affect the video's quality, sound and bitrate.
Video size: If you want to record HD video, just select "HD Mode", one of the "original quality" is the best, but the resulting file and network code flow will be the largest, "super clear quality" slightly less clarity, but a small half of the file, fluency will also be much higher, you can choose 1/2 size, will be recorded in half the size;

Compiling ffmpeg (svn version) and x264 (git version) decoding encoder ffmpeg in Ubuntu (Linux) is a tool for decoding and encoding multimedia videos and audio files, it is used to play and convert a large number of multimedia (mainly video and audio) files. X264 is a library file for encoding/decoding H264 video format. It is more efficient than xvid or other popular codecs and provides better image quality after conversion. Avidemux, VLCPlayer, MEnc
This article briefly translated the x264 option (encoding option, which is later called the English name) analysis report x264 codec strong and weak points by MSU lab. After reading it, I felt that the analysis was very thorough, and the method used was also very useful for reference. Therefore, I should record the key points in the analysis for memo. As we all know, there are a lot of options for x264. It is really a headache to combine these many parameters to make the encoded video smaller in
End-to-end neural network MT (end-to-end Neural machine translation) is a new method of machine translation emerging in recent years. In this paper, we will briefly introduce the traditional method of statistical machine translation and the application of neural network in machine translation, then introduce the basic coding-decoding framework (Encoder-decoder) in NMT.Reprint Please specify source: http://blog.csdn.net/u011414416/article/details/51048

It also uses the message digest to create a unique ID (also called a digital fingerprint) of the checksum and text ). When the ARJ file is signed, the checksum is calculated based on the content of the ARJ file an
The basic description of speex includes a command line encoder and decoder. these tools generate and read the speex files packaged in the Ogg container. although it can encapsulate speex in any container, Ogg is recommended as a file container. this section describes how to use the command line tool for the speex file of Ogg.
4.1 speexencThe speexenc unit is used to create a speex file through a raw PCM or wave file. You can use the following command:
