Introduction: PWM for a lot of software engineers may be familiar and unfamiliar with PWM to adjust the LED brightness For example, its essence is in every period of cutting corners, the overall performance of the LED under-voltage brightness of different effects. As you can see the seven color lantern its principle is similar, just with 3 PWM control red, green, blue three colors of the lamp output brightness, and then combined with the principle of mixing color to show the colorful effect ~Wri

Latent Dirichlet Allocation (LDA) is a thematic model that enables the modeling of text and the distribution of the subject matter of the document. The commonly used model parameter estimation method has Gibbs sampling and variational inference, there are many introductions about LDA on the net, the most classic such as "Lda math gossip" of Rickjin. The purpose of this paper is to derive the whole process of variational em.Reprint Please specify source: http://blog.csdn.net/u011414416/article/de

Computer hardware can actually be more easily divided into CPU + memory +io devices. The three of them are through a bus to exchange data, and you know in the three CPU speed of the fastest, memory second, IO device third, to make the three coordination of communication requires a certain control. 2. our CPU has its own local bus, the same memory, the local bus through the motherboard of the South Bridge chip link together to communicate.
