Dynamic Time warping DTW The distance we use most often in our daily life should undoubtedly be the European distance, but for some special cases, there are obvious flaws in Euclidean distance, such as time series, a simple example, sequence a:1,1,1,10,2,3, sequence b:1, 1,1,2,10,3, if the Euclidean distance, that is distance[i][j]= (B[j]-a[i]) * (B[j]-a[i]) to calculate, the total distance and should be 128, it should be said that the distance is ver

About DTWAlgorithmFor more information, see my previous blog: Time series mining-principles and implementation of the Dynamic Time normalization algorithm.
DTW uses dynamic planning to calculate the similarity between two time series. The algorithm complexity is O (n2 ). When the two time series are relatively long, the

DTW is mainly applied in the isolated word recognition algorithm, used to identify some specific instructions compared to good, the algorithm is based on DP (Dynamic programming) algorithm on the basis of the development. The introduction of speech recognition here first introduces the framework of speech recognition, first we have a comparison of the template sound, and then need to intercept it contains the part that really belongs to the voice, thi

This semester I have a speech signal processing course, and I am about to take the test. So I need to know more about the relevant knowledge. Haha, I have no lectures at ordinary times, but now I have to stick to it. By the way, I would like to make my knowledge architecture clearer and share it with you. The following is the first knowledge point

In daily life, the distance we use most often is undoubtedly a Euclidean distance. However, in some special cases, Euclidean distance has obvious defects, such as time series, for example, if the Euclidean distance is used, that is, if distance [I] [J] = (B [J]-A [I]) * (B [J]-A [I]) is used for calculation, the total distance and the distance should be 128. It should be said that the distance is very large, but in fact the image of this sequence is very similar, in this case, someone began to c

Although AMD's day-to-day task is to zen the momentum, but after all Zen the fastest also have to be the end of the year or the beginning of the IPO. In such a gap, the addition of the upgrade is the pain before the dawn.

Earlier graphics cards were only used for display, and then 2D acceleration components were added to the graphics card, which were used for the operation of the screen, draw points, draw lines, and so on. With the need of game, three-dimensional simulation and scientific computing visualization, the demand for 3D is gradually increasing, the early drawing work is done by the CPU, to achieve realism and real-time effect, can only draw some simple wireframe model, in the 80 's, Stanford University
The previous blogs have described some of the DRM drivers, graphics card memory management mechanisms, and interrupt mechanisms, and it should be much easier to read the AMD DRM-driven initialization process.Here is an article written by an AMD developer (put it here for the time being, and then add your own view later).Understanding GPUs from the ground upI get asked a lot on learning how to program GPUs.

scratch register will tell you which interrupt was generated by the drawing command.The fence interrupt handler function is radeon_fence_poll_locked. First read the fence number, know that the fence operation caused the interruption, when the resulting interrupt fence number is the last number, you need to assign the last fence number to the current number, while updating the fence timer. If the interrupt is not the last fence number, the timer needs to be judged and then the fence interrupt qu

This one test is the flagship model of the next generation of "Bristoal Ridge" processors: a12-9800. Compared to the previous generation of APU, this generation of AMD CPUs supports ddr4-2400 memory, NMVE protocol SSD, providing greater bandwidth and support for USB 3.1. From the extended functionality to catch up with Intel's mainstream processor. Let's take a look at the CPU performance of the a12-9800.

After restructuring, acceleration, and comprehensive transformation, AMD has been reborn. A brand new future-oriented AMD will take into account the traditional PC business and emerging business markets, and face the challenges of the cloud computing era with innovative technology, unique vision and powerful execution.
