Talk:Fast Walsh–Hadamard transform

From Wikipedia, the free encyclopedia

Perhaps put a link to my source code page at: http://code.google.com/p/lemontree/downloads/list Sometimes it seems I am the only one doing any sort of research into this algorithm, and even then my efforts are strictly at the hobby level. Nevertheless I have made great progress in finding uses for this ultra-fast transform.

My last efforts to help out at wikipedia were stymied by a Peter Pan character living in a bedroom in his parents house somewhere in England. I guess there is a "No Adults Allowed" sign hanging on his bedroom door. The polite English solution to an adult child who is showing no sign of maturing or moving out is to send them on a world tour for a year. I have met many of them in Thailand. They are harmless enough, they just hammer away on there guitars until 3 am in cheap hotels keeping everyone awake and babble among each other about music, the immaturity is something else though. By the time "the offer" is made I am sure there is an implied "Or get out anyway" attached to it. Even though it is an expensive option for the parent, at some stage it must be worth it. Like going to work bleary eyed and exausted because the "twit" was hammering away on his guitar until 1 am. An the mother finding her work and social life as constrained as when he was 12. "I'm sorry I can't have lunch with you today, I have to go home and make my 23 year old son his lunch and wash his dirty underpants for him". Hatom (talk) 15:47, 25 May 2008 (UTC)

There are 2 main algorithms for calculating the Fast WHT. An in-place algorithm and an out-of-place algorithm (pictured). Both are useful and can be mixed together. Although the algorithms are simple they interact with the different memory levels in a modern CPU in a very complex way, register memory, L1 cache, L2 cache and main memory. This makes it rather difficult to find an optimal memory access pattern for actual implementation. I have done my part. I cannot do anymore work for free. I must earn money for my wife and child. I think you can push things much further than I have. In particular everything I have done needs too be put on a serious mathematical footing. I do think that a credible computer scientist should publish a paper based on my work. I have not been able to do a full literature search, only a web based one. I believe most of my work is unique.
