- Hi, everybody.
-
- I'm a computer science student at Copenhagen University (DIKU) who is
- facinated by neural networks. This week IEEE held a workshop on neural
- networks for signal processing (NNSP) at Helsingoer here in Denmark - I just
- couldn't let that opportunity go, so of course I went there :)
-
- About 30% of the time was devoted to speech & NN, and one of the papers I
- found interesting was titled: "Unsupervised Sequence Classification" by Jorg
- Kindermann and Christoph Windheuser. I'm not sure which of them were at the
- workshop, but I think it was Joerg Kindermann. He presented a novel idea (as
- far as I know) that made his kohonen network able to recognize speech of
- varying speed(!) (up to 20%) I have never seen this done before so I was
- really impressed.
-
- He used seval layers to recognize sequences of increasing complexity. The
- net at the workshop had 4 layers and was able to recognize phonemens. (He
- told me that they had build a 15 layer network to recognize a specific long
- German word!)
-
- The neurons each had two inputs, one with a delay and one without. To
- activate the neuron both inputs had to be active at the same time. The
- neuron stays active (hysteresis?) until both inputs are inactive.
-
-
- As I said before, I'm a student (haven't even got my masters yet), so please
- bear with me if I have misunderstod something. What I would really like to
- know if this IS a novel idea? I suspect somebody might have tried something
- simmilar with TDNN. Any coments?
