Echo State Neural Networks
Echo state networks (ESNs) are a novel approach to recurrent neural network training with the advantage of a very simple and linear learning algorithm. It has been demonstrated that ESNs outperform other methods on a number of benchmark tasks. Although the approach is appealing, there are still some inherent limitations in the original formulation.
Here we suggest two enhancements of this network model.
First, the previously proposed idea of filters in neurons is extended to arbitrary infinite impulse response (IIR) filter neurons. This enables such networks to learn multiple attractors and signals at different timescales, which is especially important for modeling real-world time series.
Second, a delay&sum readout is introduced, which adds trainable delays in the synaptic connections of output neurons and therefore vastly improves the memory capacity of echo state networks.
It is shown in commonly used benchmark tasks and real-world examples, that this new structure is able to significantly outperform standard ESNs and other state-of-the-art models for nonlinear dynamical system modeling.

Dollar Plunges to Record Low Against Euro2004-11-05 11:47:01 by ---
NEW YORK -- The dollar dropped to record lows against the euro on Friday, succumbing to negative sentiment and erasing all of the U.S. currency's earlier gains following a robust U.S. October employment report.
Technically driven trading also played a role in the dollar's fall.
The euro surged above $1.2900 and then breached the prior record high around $1.2927 hit in February, reaching new record peaks around $1.2950, according to Reuters data.
The dollar index, a measure of the U.S. dollar's performance against a basket of currencies , fell to a nine-year low. The U.S. currency also fell to six-month lows against the yen and 6-1/2 month lows against the Australian dollar.
Traders were struck by the dollar's inability to sustain a robust rally fueled by the...
I gave up watching tv about 3 - 4 years ago.2005-04-11 21:02:11 by FellowTraveler
I now use my tv for watching rented movies or programs I taped and collected before.
I do miss the history channel and other educational stations,
but over all I have more time for other activities the likes of this forum etc.
Now back to an issue of money :)
So called "free trade" works for this country under the guide lines of national security,
though the cost of this free trade is becoming very heavily taxed :)
This monopoly of money(currency) we are allowed to use - is controlled as it's tradable value-
One of the hidden taxation is inflation,
a million has the buying power of just a half million within less than a decade.
This fact keeps us on the treadmill of buy and selling (trading-investing),
else our savings soon...
