Experimenting High Frequency Trading Principles on Twitter

A common issues is “how to attract people attention to my web page/twitter when I don’t have any reputation?”.

Few months ago I was invited by Stephane Degoutin at the ENSAD aka ‘Art Deco’, a design school to co-organize a 1-month workshop with students about experimenting new forms of crowdsourced art using Mechanical Turk, a Amazon labor market service for micro-tasking I used for my own scientific experiments. The goal of the workshop was ...

Crowdsourcing satellite imagery (part 1): Meritocracy technics

With the emergence of web 2.0 practices, new participatory approaches in GIS emerged for the last decade.

Paticipatory modeling: citizens as environmental modelers

Can we complement or even replace physical laws by the experience of local people to model environmental phenomena? An article from [1] showed that an air quality map generated by local people could be of a good quality compared to one generated by a physical model?

In the context of a participatory and cost-effective process to monitoring  natural resources, pollution or other kinds of commons, can we also empower local communities to form an emergent computation model of a local phenomenon using their tacit knowledge coupled with real measurements?

DIY: sensing/quantifying your food, money and tv consumption

The question of who owns the data we generate on Internet is a common and challenging problem (e.g. all privacy issues about Facebook). However, we don’t talk too much about our real life.

NoiseTube: Participatory sensing for noise pollution monitoring

Issue 1: Pollution assessment:Currently the assessment of population exposure to pollution is a real problem due to the complexity to measure it. For officials, measuring exposure at an individual level for a citywide population is viewed as impractical. Other approaches such as simulation are thus often required, with all their uncertainties. Furthermore real time city ...

Information overload: before solved 100% by computer, now 80% computer/ 20% human Before a lot of hard problems were solved only by computer. Humans were considered only as end-users. Since the democratisation of Internet and the integration ...

I chose a paper called “Behavior Learning and Individual Cooperation in Autonomous ...

Peg Solitaire game solved by genetic algorithm

I’m currently trying to publish some old projects done in my school period. Few days ago I retrieved a paper written in 2002 (in french) about the resolution of the Peg Solitaire game. It’s a NP-complet game. However with the use of genetic algorithm, backtracking technics and the symmetry of the problem, a solution (i.e. ...
