I have already seen a lot of implementations for the Hopfield net, so I'm really interested in seeing other types of nets, or if not, someth i ng new in these nets (like a ckt. that incorporates the learning rules). I am currently working on a VLSI architecture for the Backprop. algo., maybe we could exchange ideas. You may mail me directly at castillo@eel.upc.es if the subject matter is not of general interest. T.Y. Francisco Castillo. ------------------------------ Subject: Any Neural-Net Accelerator for the PC? From: Ran Ginosar <ran%techvlsi.technion.ac.il@CUNYVM.CUNY.EDU> Date: Fri, 05 Oct 90 00:56:37 +0200 We are looking to buy an accelerator for the PC for neural network computations. Any recommendations or suggestions as to what's available, what to buy, or what not to buy? Please mail directly to "ran@ee.technion.ac.il" and I will summarize the results for the net. - Ran Ginosar Technion, Israel ------------------------------ Subject: Would anyone take on a part-time research student? From: Andy Holyer <and@ux.rfhsm.lon.ac.uk> Date: Mon, 08 Oct 90 15:04:00 +0000 I have been granted the concession from my department of being able to devote a certain amount of my time on research work (if I can get a project going). I need currently to get some form of postgrduate qualification (to cover up my undergraduate degree), and I would like to start an M.Phil./Ph.D; I'd like to look at connectionism. Is there anyone out there who would take on a part-time, external research student? There's nobody here who even knows what a NN is, letalone being interested in supervising. Any fees incurred I could *probably* be able to cover out of my own resources. For obvious reasons my order of preference for locations is London/S.E. England/U.K./Europe/Anywhere else :-) If anyone's willing to help, mail me directly and we can talk about the things I'm interested working on.

At the time, I mentioned that I had a paper in the works which was soon to be completed. Unfortunately, my work schedule did not permit me to complete it until last week. In any event, it is now available. You can get a post script copy via anonymous ftp (described below). If this is not satisfactory, please e-mail me a request and I will mail you a hardcopy. The title and abstract are included here: "Backpropagation Learning for Multi-Layer Feed-Forward Neural Networks Using the Conjugate Gradient Method" E. M. Johansson F. U. Dowla D. M. Goodman Lawrence Livermore National Laboratory Abstract --- In many applications, the number of interconnects or weights in a neural network is so large that the learning time for the conventional backpropagation algorithm can become excessively long. Numerical optimization theory offers a rich and robust set of techniques which can be applied to neural networks to improve learning rates. In particular, the conjugate gradient method is easily adapted to the backpropagation learning problem. This paper describes the conjugate gradient method, its application to the backpropagation learning problem, and presents results of numerical tests which compare conventional backpropagation, steepest descent, and the conjugate gradient methods. For the parity problem we find that the conjugate gradient method is an order of magnitude faster than conventional backpropagation with momentum.
