CAPTCHA's did nothing to prevent spam for us. However simply disabling users We initially allowed plain text links but spammers seemed happy to just post them. Spammers want to post hyperlinks, without that ability they can't do anything.
Advances in storage and compute have led to a disturbing fetishization of machine learning. While the modern Machine Learning Movement makes sense in a historical context and is a reasonable reaction to the disappointing returns from symbolic inference during the early days of AI research, it is terrifying that the research community is satisfied to rely on big data and statistical methods to carry us forward. Few am…
Numenta has pulled crap like this before. We know patents may be pending, but you don't have the epistemological right to go blowing the Great Shofar for the invention of True AI with a link to your company's website and a fancy buzzword about neural or cortical this-and-that on the front page. We need to see some published research, or you need to take over the world. Preferably the former.
Until then, stop making claims unless you want the rest of us to consider you a crackpot and a braggart.

"Even though an amplifier and a computer are both made of transistors, they have almost nothing else in common. In the same way, a real brain and a three-row neural network are built with neurons, but have almost nothing else in common." -- Jeff Hawkins (On Intelligence) One example is that most NNs neglect the time domain. A balanced approach recognizes the importance of learning from data, but does not _rely_ on bi…
As a counterpoint, nearly all human technical advances (flight, propulsion, energy, computation) did not entail examination of biological systems. And ANNs in particular share a host of problems with statistical techniques: black-boxish behavior with lack of human-accessible state introspection and poor tractability.
I have a philosophical question in response to this. Is it even possible to have intelligence without it being a black box? Are people willing to call something intelligent if they completely understand how it works?
Computers can simulate everything from visual character recognition to mouse movements and everything else we do online. My prediction is that Google will one day enter the "Bot Recognition Market". They've got so much data on everyone and their browsing habits from Gmail, to Adsense, to Search results, to Google Analytics. Their cookies, browser, javascript, and ads follow you around all over the internet. They're t…
The part about Google offering a sort of vetting service sounds quite plausible, in a "Oh, shit" kind of way. For those of us that try to be anonymous we could have further encumbrance dealing with not being "Google Verified™".

Make links remain as plain text (so they are plain text as far as google is concerned)
then use javascript to turn them into clickable links when the user mouse is over or near the link so the user can still click on them.

We use honeypot field and timegate trap on our site forms - so far very successfully.
I know what a honeypot (fake field that only bots fill out) but what's a timegate trap? Googling didn't bring up anything relevant. Does it check how long it took the user/bot to fill up the form and dismisses it if it was too fast?

Yep. My first thought was, what, not 100%? Then I realized that I missed 3 out of 5 myself the other day.
Perhaps the next level is to realize that getting 3/5 means you are human. ;)
