How Facebook Deal With Their Masses of User-Generated Data

How Facebook Deal With Their Masses of User-Generated DataFor decades, companies have lived by the mantra “customer is king”. But in the age of the Internet- when users generate hoardes of data, not all of which is useful or accurate- the rules of the game have changed. We recently spoke to Tye Rattenbury, Trifacta’s lead Data Scientist, about how he dealt with the masses of user-generated data in his previous role at Facebook, as well his current role with Trifacta. Tell us a little bit about yourself and your work. I joined Trifacta at the beginning of June of last year. So I was in grad school at Berkeley with the co-founders Jeff Heer and Joe Hellerstein. I had worked with Joe at Intel- he was managing the Intel Research Programming Lab. I was working for Intel in...

Stack Exchange Gain $40m to Become to Sole Platform That Matters for Dev Hiring Companies

Stack Exchange Gain 40m to Become to Sole Platform That Matters for Dev Hiring CompaniesStack Exchange the startup behind the popular Q&A platform for professional and enthusiast programmers, Stack Overflow, has secured $40 million in investment in a Series D round of funding, it revealed earlier this week. The round was led by Andreessen Horowitz and saw participation from existing investors like Union Square Ventures, Spark Capital, Bezos Expeditions, and Index Ventures, bringing the total funds raised till date to $70 million. Founded in 2008, the startup’s Overflow platform has garnered tremendous respect within the developer community owing to its no frills, programmers-first policy. “Everything about how Stack Overflow works today was designed to make programmers’ jobs easier. We let members vote up answers, so we can show you the best answer first. We don’t allow opinionated questions, because they descend into flame wars...

The Most Interesting Man in Data Science

14972885269_cd0bce0c63_kFrom apple grower to fine arts student, from software developer to machine learning PhD- Jose Quesada has done it all. Now, he’s established Data Science Retreat, a course to help people with his passion for growth and development to delve into the world of data science. We recently spoke to Jose about his remarkable story, the Data Science Retreat experience, and why so-called “soft skills” are often the making of future data scientists. Give us a brief introduction to you & your work at Data Science Retreat. I love developing people. When I see the ‘delta’ on a person after hard work, it makes me feel good. Data Science is ‘the’ place for this ‘huge delta’ development: because the state of the art is changing rapidly, you are forced to...

Facebook Open Sources Deep Learning and AI Tools on Torch

twitter-292988_1280Facebook in an unprecedented move has open-sourced some of its machine learning tools with the scientific computing framework,Torch. The announcement came earlier last week on Friday, through the Facebook AI Research (FAIR) blog. “Today, we’re open sourcing optimized deep-learning modules for Torch. These modules are significantly faster than the default ones in Torch and have accelerated our research projects by allowing us to train larger neural nets in less time,” wrote Soumith Chintala for Facebook. The blog outlines that the release includes a number of other CUDA-based modules and containers: Containers that allow the user to parallelize the training on multiple GPUs. An optimized Lookup Table that is often used when learning embedding of discrete objects (e.g. words) and neural language models. Hierarchical SoftMax module to speed up training over...

Mario Gets Self-Aware with Application of Artificial Intelligence

Mario Gets Self Aware with Application of Artificial Intelligence AIResearchers of the Cognitive Modelling Group at Germany’s University of Tubingen have developed the Mario AI Project wherein a self aware Mario who makes decisions based on what it learns through spoken instructions or concepts and by exploring his environment. Mario here has also been programmed with internal emotive states which articulates into feelings. He interacts autonomously with the researchers and his although slow, his progress is ongoing. The Cognitive Modelling team has released a video to document how the artificial intelligence works. Carnegie-Mellon’s Sphinx speech-recognition toolkit has been utilized to enhance Mario’s understanding of English sentences and commands, reports VentureBeat. An effort to unravel the workings of the human brain, the team also disclosed that this project has generated “a fully functional program” and “an alive and somewhat intelligent...

How We Can Use Data Mining to Fight Corruption

The Potential of Fighting Corruption with Data MiningData Mining is an analytic process designed to explore data (usually large amounts of data – typically business or market related – also known as “big data”) in search of consistent patterns and/or systematic relationships between variables, and then to validate the findings by applying the detected patterns… Two centuries ago, coal mining spurred the European continent’s Industrial Revolution. Today, data mining is fueling the data revolution brought about by exploding streams of data. Using data mining techniques to profile customer preferences and predict purchasing patterns has become common practice in the private sector. But can data mining also be used to fight corruption? And if so, how? Last year, Transparency International Georgia launched an open-source procurement monitoring and analytics portal, which extracts data from the government’s central e-procurement website...
