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

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

Dubai (2) initial impressions
It takes me about eleven and a half hours to fly to Dubai. This flight is the most memorable one of all my trips, making it hard for me to forget.
I know that all airports are cold, and I know that it is also cold on the flight. This time it was cool. Let me start to have a migraine shortly after the flight, and then start to vomit Qi, Qi, Ba. I couldn't help it, but I neede
Dubai (1) secrets
Going to Dubai should have been an accident. It would have been less than a month since the end of the trip. Actually, if I wanted to go, I went there. This is also a different number in my life.
Think about it. I have a lot of problems with this person: From the vanity, impetuousness, and inattention that I have long recognized, I discovered that I had to add a three-hearted mind. W
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
This series describes several sequence alignment methods, including dynamic time warping (DTW), Smith–waterman algorithm,cross-recurrence plotDynamic time Warping (DTW) is a well-known technique to find an optimal alignment between both given (Time-dependent) Seque NCEs under certain restrictions. --meinard Muller "Information retrieval for Music and Motion"dtw

Plants in the desert
The whole sand dashboard is not very long, and it is only an hour when it is full. It's not that deep into the desert, that is, a few minutes to half an hour. It is sand dashboard, that is, a small area of ground. For those of us who enter the desert for the first time, we cannot find the southeast or northwest. However, there are some plants in the desert, which surprised me a lot. I still found my own e

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
In Shanghai, there are often such intersections, there are no traffic lights, or there are traffic lights and they are green, but there are turns of motor vehicles, small turns of motor vehicles.
In most cases, the car will slow down, but it does not clearly indicate that he will let you go first. He is watching. if you don't slow down, you should first; if you are afraid, standing up, he will step on the accelerator.
Sometimes standing in the middle of the road is very dangerous.

Then, when the forward search reaches the zero-crossing rate, it is always greater than a preset threshold,This is the starting point of the speech segment. Short-term energy is used for the end point determination,That is, if the energy value of several consecutive frames is smaller than the preset threshold value, the speech segment ends. The ac
