Clash Royale CLAN TAG #URR8PPP What is the difference betwee Yaafe and PyAudioAnalysis? I'm new to audio feature extraction. It seems like Yaafe (and its Meyda Javascript clone) and PyAudioAnalysis are the two biggest libraries, but I can't find a comparison of them anywhere. Can anyone tell me if either one has more features, or is better suited to a different type of task? I'm aiming to generate graphical scores automatically based on features extracted from mp3s.

But its inserting duplicate rows in DB. The issue here I am facing is: 1. I am getting two values for primary key. One when I invoke the flushPerson() method to get 'id' before persisting Person Object. 2. Other when I invoke save method, to save Person object. In this method also 'Id' is getting incremented.

Clash Royale CLAN TAG #URR8PPP Neural net with duplicated inputs - Keras I have a dataset of N videos each video is characterized by some metrics (that will be inputs for a neural net) my goal is to predict the score that a person will give when he or she watches the video. The problem is that in my dataset each video was watched more than once by different subjects, so I was forced to duplicate the same metrics (inputs) the number of time the video was watched to keep all the scores given by the subjects. I built an MLP model to predictet the scores. But when I calculate the RMSE it's always higher than 0.7. I want to know if having a dataset like that would affect the performance of my model ? And how can I deal with it ? Here is how the dataset looks like: The first 5 columns are the inputs and the last one is the score of subjects. Note that all of them are normalized. Here is my Model: def mlp_model(): # create model model = Sequential() model.add(Dense(100,input_...

Clash Royale CLAN TAG #URR8PPP I want to create Audio calling App in android studio with FCM is it possible I am trying to build a simple chat application, but it requires Voice calls functionality to other users. I would be using Firebase for messaging. Does Firebase have Voice calls support? 3 Answers 3 You can use WebRTC for Audio call and use FCM for signaling. But Firebase as a service does not provide any support for Audio/Video calls. You can also use third party SDKs like Twilio. no firebase does not support voice call support. It is support service like push notification using FCM. Please doc. of firebase – Sourabh Patil Aug 10 at 11:43 @SourabhPatil, documentation contains only what it does support , no what it does not . – Vladyslav Matviienko Aug 10 at 12:10 yes exactly right @VladyslavMatviienko – amit Aug 10 at 12:15 @amit thnx for help – Sourabh Patil Aug 16 at 10:22 FCM is for push notificat...

Clash Royale CLAN TAG #URR8PPP Multi otsu(multi-thresholding) with openCV I am trying to carry out multi-thresholding with otsu. The method I am using currently is actually via maximising the between class variance, I have managed to get the same threshold value given as that by the OpenCV library. However, that is just via running otsu method once. Documentation on how to do multi-level thresholding or rather recursive thresholding is rather limited. Where do I do after obtaining the original otsu's value? Would appreciate some hints, I been playing around with the code, adding one external for loop, but the next value calculated is always 254 for any given image:( My code if need be: //compute histogram first cv::Mat imageh; //image edited to grayscale for histogram purpose //imageh=image; //to delete and uncomment below; cv::cvtColor(image, imageh, CV_BGR2GRAY); int histSize[1] = 256; // number of bins float hranges[2] = 0.0, 256.0; // min andax pixel value const float* rang...

Clash Royale CLAN TAG #URR8PPP C# sqlite entity framework - map string type In SQLite in table I have column: Title and type of this column is string. Now I want to map this table to Entity Framework in C#. And problem is with type string of that column because I cannot map it to string type in C#. It works when I change in SQLite string to VARCHAR. But how to resolve this problem without changing column type? 1 Answer 1 Most SQL database engines (every SQL database engine other than SQLite, as far as we know) uses static, rigid typing. With static typing, the datatype of a value is determined by its container - the particular column in which the value is stored. SQLite uses a more general dynamic type system. In SQLite, the datatype of a value is associated with the value itself, not with its container. The dynamic type system of SQLite is backwards compatible with the more common static type systems of other database engines in the sense that SQL statements that work o...

Clash Royale CLAN TAG #URR8PPP Avoid Index Out Of Range error in swift In my UICollectionView I'm trying to return 1 item, if there's no data (in order to set an empty cell then). Here is the code: var movies = [Movies]() func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int if movies.count == 0 return 1 else return movies.count I'm getting Fatal Error: Index Out Of Range. I know, that this way I'm trying to access an element under index[1] and that's impossible, because that element doesn't exist, that's the reason of this error. But how can I avoid it in this case? In this function you are saying... If I have no items... tell the collection view that I have 1 item. If you just return movies.count here your problem will go away. Also... your crash is not here... it is somewhere else. – Fogmeister Aug 10 at 11:36 movies.count 1 Answer 1 As of you are returning 1 count in numberOfItemsI...
