NMF (non-negative matrix decomposition), because its decomposition of the matrix is non-negative, in some practical problems have a very good explanation, so the use is very wide. Here, I would like to introduce the application of NMF in the multi-part music. To translate the paper is the use of NMF transcription multi-part music of the mountain, simple and easy to understand how to use the NMF to the piano score translation, it is worth a look.Summar

TCP/IP network programming (transcription Note 5) –select and IO multiplexingUsing fork () to generate a child process can reach a server-side request that can respond to multiple clients at the same time, but this has drawbacks:Requires a lot of computing and memory space, each process must have a separate memory space, data exchange is also cumbersome (IPC, such as pipelines)IO Multiplexing:Ethernet bus structure is also used multiplexing technology

Chinese phonetic alphabet In normal applications, you may need to enable automatic phonetic injection for some Chinese characters. This program is implemented according to this requirement. Thoughts The idea of the Chinese phonetic alphabet program is mainly dependent on the phonetic vocabulary of some existing commonly used words. For a given Chinese character string text that requires sound injection, text is first segmented. The word segmentation method here adopts the methods to combi
