Artistic BCI

Upon hearing first of BCI (brain-computer interface) technology several years ago, my first thought was not “wouldn’t this be useful for medical patients?”, but rather “this holds an amazing amount of promise in the arts”. Everyone seems to be thinking about low level spatial movements – things on the order of controlling limbs with thoughts or – if they’re ambitious – moving pointers across a screen. None of them seem to be thinking thoughts such as “Can we decode artistic or musical ideas and represent them instantly on a computer?” Now that would be amazing.

It’s a significant research challenge, but the idea needs to be present before the research can begin.

Using tensors for spatial k-means

Using k-means clustering on spatial data requires linearization of the dataset. This causes pixels on the right of one row and on the left of the next to be considered neighbors in a traditional linearization scheme (using a Hilbert curve might be a better idea), which is inaccurate. This stems from the fact that observations are stored as a matrix: observations in the rows, features in the columns. Using tensors, it seems we can store the spatial information as well as any constituent features – the dimensionality of the dataset would then be the rank of the tensor – 1, with the final dimension reserved for features.

That would seem more efficient. Maybe I should see whether it has been done already.

The Polymath Lectures

I know how I can kick off the fundraising for the Polymath Foundation once it’s incorporated.

I’ll give online lectures on IT and programming topics. The fee to attend will be modest, with suggested donations possible based on how good a job students think I did. All of the proceeds will go to the Polymath Foundation. Considering that I already have an MS in Computer Science and I’m well on the way to a Ph. D., I should have little trouble convincing people I’m qualified.

I’m not going to ask the other board members to do the same, but they’re welcome to if they find it fun.

Electrostatic Attraction in Society

I’ve been thinking about how many issues I’m perceiving in academia vs. my friend, whom I have always thought was much more suited to an academic lifestyle than I was despite us having similar ability (and indeed, he’s having a better reception than I did thus far, although he’s had his share of troubles too), and it made me realize that it could very easily be described in terms of a force. I originally thought gravity, but on second thought, the electrostatic force seems much more appropriate:

People in any particular niche of society (academia, industry, the arts, etc.) have views of any particular person based on what type of person they perceive him to be. This may have little to do with the person’s actual character; just how it is perceived (think of how all of chemistry is founded on the reactions of the valence shell rather than the nucleus). This can cause an attractive or repulsive force between a person and the niche. The person’s own views and choices also influence this force; so it is, in a way, symmetric.

These are charges. The composition of these charges determines one’s entire reaction in society, and to a large extent, what path an individual takes.

For example, no matter how much I try to learn, I think I must acknowledge that there is a repulsion between myself and academia. I cannot tolerate the nonsense, the bureaucracy, and the intolerance to new ideas, and perhaps they cannot tolerate my propensity for choosing fields that are not “hot”, my wish to devise and stick to a plan with a strict timetable, and what they probably perceive as a lack of flexibility. No matter what I do, I am forced into unpleasant scenarios in academia because of this conflict.

Conversely, I am drawn to industry without making any effort of my own to do so. The job offers streaming in are not a coincidence, nor are they solely attributable to the position of my resume in a search (although that helps), since I’ve also received them on sites such as LinkedIn (and even Facebook and MySpace). They probably perceive intelligence, a good work ethic, and ambition – whether I truly possess these qualities or not is as irrelevant as the nucleus of an atom is to reactions of its valence shell. Since I don’t particularly have any aversion to industry (my charge is neutral?), the overall force is attractive.

The result is that when I had a strong desire to enter academia, it drifted me over to academia, though not swiftly or completely enough to counter the repulsion I met from academia itself. As that desire began to fade, I began to drift away, to be drawn in on the stronger current of industry.

In summary, it seems that my own life, at least, can be described fairly well in terms of such charges.

Recruitment on a fixed schedule?

I think I’ve figured out why I never get just one contact from a recruiter in a given day anymore. There must be a schedule that recruiting firms and/or HR departments operate under.

I received two today: one was from Bloomberg, the other from a company that appears to do VPN and network cryptography.

It would be so easy to just leave academia! Industry has received me so warmly (some of the recent offers have six figure starting salaries), while all academia has done is make demands of me… demands for ever greater effort with ever diminishing rewards. I can’t even pursue my academic interests within my field, much less the wide spectrum of interests I have overall. Ironically, several companies have promised me precisely the sort of training I can’t attain in an academic institution. If I want to truly do research, though, I need to see this through to the end. Once I graduate, I’ll be free!

I think it’s time to get back to seriously working on my dissertation. So long as I worked on it alone without someone else’s inefficiencies constraining me, I made very good progress… but waiting for a review of the first draft shattered my momentum.

Procrastination and Anticipatory Fatigue

There’s a paper I need to continue working on today, but I’ve been writing papers all week and I’m exhausted. Nevertheless, I decided at this point that it was unwise to delay any further.

As soon as I resolved to begin it, I felt like all of the energy left me.

This was somewhat surprising, as I had expected that the fatigue associated with the activity (a feeling I always associated with about 2:00 PM on a 9-5 schedule of a boring job, probably because I tended to finish my work around 1 PM) would have an onset after work began. That does not seem to be the case, and may explain the root cause of procrastination – if one feels fatigued or otherwise unwell prior to beginning a task, he may never actually get around to doing it.
