In fact, sometimes, not often that I have not fully understood the process sample / demo in, began to apply, Kaka substituting a pass, there are many ideas for granted, are wrong.
If the sample so completely as to simple words, the entire feature can be directly taken avg, characterized in still very clear, as follows:
The x-axis is characterized 128D, y is the time dimension frame, is determined by the length of hop_size
That is, after the FIG taken avg FIG.
Compare the following under the same category avg features are similar?
Overall, we do have similarities, but dubious, why so much alike? ? ? Afraid of different categories is so similar, it can not play.
Extraction category features Lau and Dan, tsne look at the map, and then do the next query to see how it works.
After the PCA 30D, perplexity 50
There is a certain degree of differentiation, but there are still one of the possibilities: because there is no classification boundaries.
Perplexity of 100
Dan has joined a number of categories mnw, pseudo-labeled 2, after the PCA 30D, 0.86, perplexity 100
0 and is a Class 2, Type 1 is Lau, sacrifice the long corner, little difference can be considered
Because of the color problem, Lau set to 3, all other categories of Dan
Most are located in the red box Lau, Lau add data points, as follows
Division I point increase below Lau, 1000 Ge shown in the lower, marked 4, [Note: The above only with the vibrato of Lau, Dan is our]
The combined 3,4 3 If, as follows
I think the time may also try to increase the point long, or directly with the entire duration [not including the last attached sound of vibrato]
Personally feel that the long-Lau much should be different with Dan, features more obvious, is not it? Wait and see
[Encounter a problem, do not know how to specify a GPU, after a specified not so that , because I want to run two or more scripts, each with a GPU, has written an article before, but did not get to the bottom . Here to add next]
Today, in advance to go back to collect her things. Commute
