  • 1. what do you thing about image processing by MLP
    hi, i'm implementing a MLP for processing image (smoothing, noise, raising contours, etc...). But, I found in a book (adaptative image processing by Stuart William Perry, Hau-San Wong, Ling Guan) that we can also do it with the kohonen networks. I'm wondering what's the best for image processing in general. If someone has idea or knows someone who had already compared it,thanks I'm searching in the citeseer site, but i found nothing about it.
  • 2. Implementing Loss Matrix in MLP
    Hello All, Many thanks to all the contributors here. I'd like to implement a loss (cost) matrix in an MLP but have found very few detailed descriptions of this (even Bishop's text has little on this). My initial assumption is that I should add an 'Omega' term (penalty to the error function) much as done in the Regularization section of Bishop's 1995 text (sec 9.2). Such an approach I (heuristically) argue should work much as weight decay does. However, the penalty in this case could be quite "quantized" (changing suddenly in jumps) and might therefore fail to give the network useful guidance (that more continuous changes should) in finding what might be the better solutions. Thus I suspect that there there may be better or alternative ways. Can anyone point to observations or experiences on implementing loss (cost) matrices for the MLP? With thanks, Dave

I have only had this vacuum a year, I'm not crazy about it. The attachments have to be used in conjuction with a tube with a flap on it, and the flap broke off, now if I want to use the attachments I have to block the hole with my hand or watch everything shoot back out. It also keeps tipping over on me. Othewise ok,
After reading the reviews, I had to issue my own. I purchased the Hoover Supreme Mach 3.3 Windtunnel in '96 or '97 and it is still going, however, just recently,the motor is making a loud noise just as I shut it off. I suppose it is finally dying. It has gone thru three remodeling projects over the years and only problems are belt replacements 3 or 4 times which I found no problem replacing myself as long as I have the right belt to replace it with. It does tend to tip unexpectedly and bags need to be replaced when only half full for best suction. After the brushes on the roller wore down, I had problems picking up fuzzes/strings ( I sew alot) from a tighly woven carpet - needed a lint roller! Instead of replacing the roller at $40.+ I'll put that toward next vac. Sounds like this may have been one of the better models Hoover has made over the years.
This is a good vacuum for people with pets I have a dog, 2 cats, 2 hamsters that are very hard to clean up after the Hoover U5453-900 WindTunnel Supreme Upright Vacuum Cleaner does the job.The things that I don't like is that it clogs if you don't change the bag after about 6 days.And every time I suck a string the belt breaks.This is agood product but it EATS BELTS.
I've had my Orek since 1998 without any problems. I bought the Hoover Windtunnel (on the recommendation of my sister and sister-in-law) 2 years ago, and this is the third time it needs to be serviced. The first two times it was under warranty -- the first time was because the carpet-height tabs broke off (which I was then told happens frequently); and then because the vacuum wasn't picking up. Not sure how they fixed it -- it may have been a belt. Now the Embedded dirt light is not working -- it's staying on red/dirty. It may be a gimmick-type feature, but I'd prefer that it work. Maybe the Orek has lasted so long because there aren't so many features. In any case, it's dependable, easy to use and light weight.

The Hoover Windtunnel is VERY heavy -- if you're not using the self-propelled feature. One thing I will say...when it works, it does seem to work well.
