Workshop interne avec l’équipe de l’EPFL-ECAL-lab pour évaluer lubyk. Si tout va bien, on aura quelques démos à mettre en ligne…
Nous travaillons actuellement sur le spectacle des bateaux pour nulle part prévu pour janvier 2013.
Mr Butenko presentation
Overview of Mr Vitalijs Butenko’s final presentation today in EPFL.
Mr Vitalijs Butenko has been working on the movement recognition for the last 6 months and gave his final presentation today in EPFL. We could do a live demo with the recognition of 5 classes triggering sounds.
Here is a table taken from Mr Butenko’s research showing the error rate on the recognition of the 7 movements recorded by Nicholas Petit here in January.
| W=50 | W=75 | W=100 | computation time | |
|---|---|---|---|---|
| k-means | 42% | 38% | 36% | < 0.5s |
| DTW | 27% | 20% | 12% | > 1s |
| SVM | 0.8% | 0.8% | 0.5% | < 1s |
| Error rates for 3 window sizes @ 256 samples/second | ||||
From this table, we see that support vector machines looks very promising with less the 1% error ! And the best is that there is a free library with ruby wrappers available : libsvm.
As soon as the rubyk editor starts to work, we will jump into this new classifier.
Many thanks to Mr Butenko for his great work.
