    True, but isn't that a different problem?

    I admit I'm a bit clueless here, but AFAIK climate modelling deals with overall changes at a high level e.g. "It's going to be colder in the north atlantic by about 2 degrees on average in a few decades" and the like.
    As opposed to weather prediction which says "It will rain in this spot on this day"

    Just because we can't predict the 'noise' in the short term doesn't mean we can't determine overall changes long term.

  7. Re:NOOOOO on Eigenfaces Online Service · · Score: 3, Informative

    It's named eigenfaces because the underlying compression technique uses eigenvalues/vectors.

    It's called PCA (principle components analysis) and works by finding an underlying low-dimensional representation that minimises the reconstruction error when you put everything back together.

    So you find a new set of basis vectors to represent the data with, where your new set is smaller than your old set.

    It turns out that the best basis used for the reconstruction is formed from the 'biggest' eigenvectors (those with the largest eigenvalues) of the covariance matrix of the data.

  9. Re:how come... on 802.11 WiFi Denial of Service Exploit Discovered · · Score: 3, Insightful
    The simple answer is that there are far more users than there were testers. When more people look at a system, it's increasingly likely that someone will 'stumble' onto a bug.

    Also, it's easier to find an exploit in an established system. Now we have lots of hardware and available WLAN access points to play about with. It's quite difficult to 'hack' a specification...

    Depends how you define intelligent, I guess (and that's probably the toughest problem with AI).

    The turing test only works in terms of 'weak' AI - that is that actions determine intelligence, and internal state doesn't matter.

    Strong AI on the other hand, says that to be intelligent, you must not only act intelligent, but also be intelligent internally.

    On the other hand, the self-preservation requirement doesn't really strike me as a facet of intelligence. A suicidal person might still have the intelligence to write a thoughtful note...

    Equivalence to a turing machine is used in lots of CS proofs even today.

    The turing test is also still considered one of the fundamental challenges of 'weak' Artificial Intelligence.

  16. Re:Language shouldn't matter! on First Java AP Computer Science Exam Complete · · Score: 1

    I know quite a few recent CS graduates that have moved straight into jobs that would be considered software engineering positions.

    I think that while most those CS graduates moving into SE jobs only found a small amount of their course very relevant, what is probably important is that each of them seems to tell me about a different part.

    A friend moving into a DB engineering post found that understanding DB query optimisation on a low level helped him out.

    Another friend found skills learned in a compiler-writing course came in useful, and another found some AI stuff to be handy.

    Maybe the point here is that a CS degree has to teach fundamentals, but also usually aims to give a grounding in a wide range of stuff that caters to as many students as possible.

    There are online methods using both the techniques you mention. The theory is usually a little more involved, so you're not likely to get a good tutorial from page 1 of google results.

    I hear all too often from people in the field of machine learning who get their favourite solution (SVMs and NNs are the most common) and then they go hunting for a problem.

    It might not be exactly the best technique, but if at the time it was the easiest to understand and use, and gave really good results, then the right decision was made.

    Is that the difference between theory and practice right there?
