Couldn’t you keep both with a fairly minimal degree of storage space simply by using either warping algorithms (and storing the deformation parameters) or retargeting whichever is the higher resolution image on the fly?
You can render a surface as a multidimensional analogue of an ROC curve for multi-class classification problems.
This one was already done: http://www.ncbi.nlm.nih.gov/pubmed/10803724
This question has been brewing in my mind for quite some time, but I don’t really know enough about how fractal/Hausdorff dimension is computed to answer it. If they can, it might be possible to obtain good compression for certain types of datasets using this property.
Has anyone ever ran fMRI or other brain imaging scans on people while engaged in the state called creative “flow” and compared it to the state of performing less involving tasks? The closest I’ve found is an imaging study on jazz improv.
In addition to composing music myself, I also know several composers. Most (including myself) appear to be introverts, but some are extroverted. One quality I’ve noticed is the differing nature of the music composed by the introverts and extroverts, as well as the ideological differences as to what music is:
Introverts appear to write music primarily concerned with emotion, thought, and reflection. They appear more likely to view music as a crystallization or actualization of emotion or some other internal state. The music itself even appears to be introverted, and can be described with terms such as warm, reflective, expressive, tormented, serene, tranquil, or haunting.
Extroverts, on the other hand, appear to write music in response to exogenous stimuli. They are more likely to compose music that evokes past experiences, and will usually cite a desire to return to the state of mind that such experiences placed them in as the motivation behind their music. Words that may be used to describe their music include evocative, motive, energetic, playful, smooth, clean, or humorous.
That’s not to say that either are “better”; they aren’t. They’re just two sides of the same human coin.
Even though I’m not the one testing it. Apparently a group of researchers also had this idea, and they, of course, have the tools to actually perform the research:

I bet the other ones do too. Just think of what I could do with the bio training I can’t seem to obtain!
Much as we like to proclaim our knowledge the result of conscious learning, learning is a subconscious phenomenon. When something truly comes naturally to you, you need not think of it anymore – it’s just there. In fact, for me at least, truly knowing how to use a technique seems to be a shift from rational processing of the problem to an intuitive understanding of it.
To me, this indicates that techniques designed to enhance the conscious aspect of learning in neglect of the subconscious are counterproductive, and it pays more to focus on techniques for promoting an environment in which your subconscious can learn.
I’ve just launched LanceRates.com, a website designed specifically to answer the question “How much should I charge?” in relation to freelance work. Users can post or look up market rates for any sort of freelance job, and the site integrates some rather advanced analysis techniques, including several machine learning algorithms, to give visitors an unprecedented level of information.
And just in case it still isn’t enough, we make the raw data available. All for free.
“New religions tend to resemble old ones because their founders tend to be religious.”
“The lack of role models during childhood is actually a precipitator of independent thought.”
“There are many ways to make money, but there is no restoring lost time.”
“Of all the evils of a society, the greatest is resistance to improvement.”
Three experts on creativity, essentially espousing the same principles I had written on my philosophy site (broad exposure to ideas, a lack of initial judgment of those ideas, taking walks and otherwise not focusing too hard on single problems, trying difficult things, …)
It really does work – these are the techniques I’ve been using in my own life.
