Investing in Individuals

Here's an interesting thought- http://500hats.typepad.com/500blogs/2009/07/taking-me-inc-p.html

It gave me an idea. Global development to reduce poverty hasn't been taken up by the private sector as much as by the non-profit/government sector. It's just not profitable without there being any barriers to entry (like a patent) after development has taken place. For example if a company built wells for clean water and roads in an undeveloped area, any other company could come and profit from that area, decreasing the ROI for the company that developed the area in the first place. However, if the development company could invest in the individuals in the area, like the article suggests, then it could make development a viable business.

For those who have never really thought about global poverty, if you look up some statistics on clean water availability, diarrhea death rates, and proportion of people living in slums, you will see that it's a huge problem and potentially a huge opportunity.

Beauty and Compression

from: http://www.springerlink.com/content/v600430w7734235j/ (not me)

I postulate that human or other intelligent agents function or should function as follows. They store all sensory observations as they come—the data is ‘holy.’ At any time, given some agent’s current coding capabilities, part of the data is compressible by a short and hopefully fast program / description / explanation / world model. In the agent’s subjective eyes, such data is more regular and more beautiful than other data [2,3]. It is well-known that knowledge of regularity and repeatability may improve the agent’s ability to plan actions leading to external rewards. In absence of such rewards, however, known beauty is boring. Then interestingness becomes the first derivative of subjective beauty: as the learning agent improves its compression algorithm, formerly apparently random data parts become subjectively more regular and beautiful. Such progress in data compression is measured and maximized by the curiosity drive [1,4,5]: create action sequences that extend the observation history and yield previously unknown / unpredictable but quickly learnable algorithmic regularity. We discuss how all of the above can be naturally implemented on computers, through an extension of passive unsupervised learning to the case of active data selection: we reward a general reinforcement learner (with access to the adaptive compressor) for actions that improve the subjective compressibility of the growing data. An unusually large data compression breakthrough deserves the name discovery. The creativity of artists, dancers, musicians, pure mathematicians can be viewed as a by-product of this principle. Good observer-dependent art deepens the observer’s insights about this world or possible worlds, unveiling previously unknown regularities in compressible data, connecting previously disconnected patterns in an initially surprising way that makes the combination of these patterns subjectively more compressible, and eventually becomes known and less interesting. Several qualitative examples support this hypothesis.
