Abstract:Abstract-It is through experience one could as certain that the classifier in the arsenal or machine learning technique is the Nearest Neighbour Classifier. Automatic melakarta raaga identification system is achieved by identifying the nearest neighbours to a query example and using those neighbours to determine the class of the query. This approach to classification is of particular importance today because issues of poor run-time performance are not such a problem these days with the computational power that… Show more
“… Chronologically, they are sampurna raaga -they contain all seven swaras of the octave in both upword and downword scale [1][2]. They are also known as krama sampurna raaga -that is the sequence is strictly ascending and descending in the scales, without any jumps or hap harard notes [9].…”

“…The process of identifying the sequence of notes i.e. the swara script is called as Note Transcription [18,2,1]. For Indian classical music, Note Transcription process itself is a very challenging task Music is represented as signal, so Note Transcription involves signal Processing techniques so that it could attract the attention of the audience.…”

“…To simplify, the type of the audio file taken as input is monophonic song with a single sound-source. System can be enhanced further for recorded Polyphonic music, by applying multi-pitch detection techniques described in [9,18,2]. After listing all the frequency segments in the audio file, each such segment has to be converted into its corresponding swara.…”

“…The precision values varied from 26% to 72% for the different feature classes. More work on genre classification was reported by Norowi et.al, [9] [10] presented an overview of techniques for Nearest Neighbor classification that placed focus on mechanisms for finding distance between neighbors using Cosine Distance, Earth Movers Distance and formulae were used to identify nearest neighbors and algorithms for classification in training and testing in order to identify Melakartha raga in Carnatic music. From the derived results it was concluded that Earth Movers Distance produced better results than Cosine Distance measure.…”
Data Mining is a powerful technology nowadays to discover and analyze large data sets. It has its applications in various fields of Arts, Science and Engineering. One such field is Music. Music is a form of arts which comes under fine arts category. It may be melody or rhythmic. It is broadly categorized as western music and classical music. Carnatic music is a form of south Indian classical music which comprises of swarams (7 notes) to evolve music. This research work deals with automatic identification of Carnatic raga Swaram notes through Data Mining algorithms. The training sets considered for the work are Avarohanam notes of 72 melakartha raga and 212 Janya raga. C4.5 decision tree algorithm, Random Tree and Rule Induction algorithm were utilized to classify the Melakartha raga and the Janya raga. However the Janya raga swaram notes were also investigated through the use of appropriate feature relevance algorithms namely Feature ranking, Correlation based Feature Selection (CFS) filtering, and Fast Correlation based Filter (FCBF) filtering. The Melakartha raga data set was accurately classified with 100% accuracy by all the aforementioned classification techniques while predictor attributes selected through feature ranking algorithm produced nearly 90% accurate classification with Rule Induction algorithm on the Janya raga data.
