Our system successfully determined the genre of the vast majority of the test songs. Not only did the system choose a genre, it quantified its output with a level of sureness.
Performance of the neural network improved with successive inputs of training vectors. It begins to recognize characteristics of each music genre!
When tested with the training vectors, the system is 87.5% accurate. Higher accuracy implies that the system has memorized the training set and is unable to generalize when given new inputs. Lighter background stripes indicate greater certainty in identification, while increasingly darker hues note greater uncertainty. Horizontal black bars indicate actual genre, and the stems indicate predicted genre.

These plots show how well the first three genres separate in the output of the network. Even the testing vectors are separated by a high degree of confidence.

Spatial separation, weighted by sureness level, of classical (red), jazz (blue), and rap (green) in the training vectors.
Spatial separation, weighted by sureness level, of punk (red), techno (blue), and country (green) in the training vectors.
Though worthy of the Museum of Modern Art, this depicts the output of the neural network for each of the six genres.
Provided songs that the network has never seen, it performs perfectly and with high confidence for rap, while classification of techno is comparably poor. However, the system is aware of this: error coincides with lack of confidence. Lighter background stripes indicate greater certainty in identification, while increasingly darker hues note greater uncertainty. Horizontal black bars indicate actual genre, and the stems indicate predicted genre.

Our system successfully determined the genre of the vast majority of the test songs. Not only did the system choose a genre, it quantified its output with a level of sureness. When the system was in error, there was a corresponding uncertainty. The genre that gave our system the most difficulty was techno. The output of the DSP functions for techno had a very high standard deviation, making it hard for the neural network to distinguish its pattern from those of the other genres. Given an unknown song, there is an 84% chance that the system can determine the genre successfully.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
