Komli offers Rs. 2,00,000 for your algorithm

Pune based startup Komli (which recently introduced the very intriguing service PubMatic) has just announced an algorithm contest, with 2 Lakh Rupees as the prize. It’s certainly a very innovative way to get a solution to your business problems, and potential recruits too.

Details:

Komli lives in the world of online advertising, and online advertising is rife with opportunity with complex algorithms based on cutting edge topics such as machine learning, data mining, graph theory, etc. Online advertising is growing at a very fast pace, and the number of variables affecting the performance of an online ad has been growing at an even faster pace. Komli is devising methods for maximizing the yield of online advertising using advanced statistical machine learning methods over large-scale systems. This is a very interesting and complex algorithm problem.

Komli is currently using a set of algorithms for maximizing the yield of online ads, collectively called ‘Yin-Yang’. There are a lot of interesting alternative approaches to Yin-Yang that have yet to be tried. Komli is interested in determining if any of these alternative approaches can beat Yin-Yang by making better predictions.

Komli will provide participants with anonymous ad impression data and a prediction accuracy bar that is 50% better than what Yin-Yang can do on the same training data set. Participants’ solutions will be judged by ‘Time complexity’ and ‘Space complexity’ criteria. The participant whose solution works best will receive Rs. 2,00,000, bragging rights and an opportunity to work with Komli. Of course, participants have to share their method and code with Komli. Eager participants can signup for the contest by filling the form on the left.

Resisting one temptation makes you vulnerable to another

Recent research suggests that:

As hu­mans, we have lim­it­ed re­sources to con­trol our­selves, re­search­ers say; all acts of con­trol draw from one source. So when us­ing this re­source in one do­main, such as di­et­ing, we’re more likely to run out of it in an­oth­er do­main, like stu­dy­ing hard.

Once these re­sources run out, our self-con­trol abil­ity is di­min­ished, ac­cord­ing to sci­ent­ists.

In an experiment, the scientists:

asked par­ti­ci­pants to sup­press their emo­tions while watch­ing an up­set­ting mov­ie. The idea was to de­plete their re­sources for self-con­trol. The par­ti­ci­pants re­ported their abil­ity to sup­press their feel­ings on a scale from one to nine. Then, they com­plet­ed a Stroop task, which in­volves nam­ing the col­or of printed words (i.e. say­ing red when read­ing the word “green” writ­ten in red), yet an­oth­er task that re­quires self-con­trol.

The re­search­ers found that those who sup­pressed their emo­tions per­formed worse on the task, in­di­cat­ing that they had used up their self-con­trol re­sources while hold­ing back their tears dur­ing the film.
