    David Filip

    Machine Learning professional / Software Developer

    Czech Republic - Last active: 02/02/2011 - Tests: 1

    Hello there, my name is David and I am writing software for 10 years. I am working from my home in Brno, Czech Republic and I am working exclusively with few companies around the Europe and abroad. I am also looking for few other opportunities to boost my income. I am quite picky selecting my customers. I am looking for people who value good work, honesty and mutual respect. Speaking of rate I am on the high end scale here on oDesk. I am working just on few projects at the time and I am always trying to over deliver. I think that my price fit my results. Technically speaking I can program in those languages: Ruby, PHP, Java, Javascript and Delphi. I prefer working with Ruby. I like to work on back-end stuff, using advanced algorithms or writing data/text processing utilities. I like machine learning, data mining and statistics. I have also experience with information retrieval, similarity searching, recommendation engines and things like this. I like to write classifiers, crawlers and working on data analysis. If you want to build something technologically advanced, you should speak with me. You might take a look to my Twitter stream: http://twitter.com/dejv

    Slater V.

    Machine Learning Specialist

    United States - Last active: 01/19/2014 - Tests: 4

    I worked as an artificial intelligence specialist at Pearson for several months after my freshman year of college. I have created novel approaches to a number of natural language processing challenges, and have soundly beat the Stanford NLP project on a number of standard benchmarks. I was scouted by Basis technologies during my sophomore year for work alongside PhDs in the field of Digital Forensics, and Natural Language Processing. I released the first and only open-source sentiment analysis library with near state-of-the-art benchmarks. I have pioneered a number of novel approaches in the fields of predictive analytics and big data analysis, regularly acting as a consultant for the Harvard Innovation Lab. I am currently working with one of the original developers of SolidWorks to create an adaptive gesture recognition platform interfacing with the Leap Motion. I'm fairly new to oDesk, and though I've used it regularly as a project manager, I've not yet signed up as a contractor. Looking for part-time work to discover cool new problems. I am extremely comfortable implementing support vector machines, genetic algorithms, neural nets, latent semantic indexing, pachinko allocation, and a wide variety of other machine learning algorithms, both supervised and unsupervised in Java, Python, C, Ruby, and Javascript.
