Yelp Dataset Challenge | Yelp | Bits 'n Pieces on Big Data R&D | Scoop.it

How well can you guess a review's rating from its text alone? Can you take all of the reviews of a business and predict when it will be the most busy, or when the business is open? Can you predict if a business is good for kids? Has Wi-Fi? Has Parking? What makes a review useful, funny, or cool? Can you figure out which business a user is likely to review next? How much of a business's success is really just location, location, location? What businesses deserve their own subcategory (i.e., Szechuan or Hunan versus just "Chinese restaurants"), and can you learn this from the review text? What makes a tip useful? There is a myriad of deep, machine learning questions to tackle with this rich dataset.

onur savas's insight:

Targeted for academic research though. The deadline is Thursday, July 31, 2014.

Flight Optimization Challenge ($250k for 1st place)

Flight Optimization Challenge ($250k for 1st place) | Bits 'n Pieces on Big Data R&D | Scoop.it
Think you can change the future of flight?

Did you know airlines are constantly looking for ways to make flights more efficient? From gate conflicts to operational challenges to air traffic management, the dynamics of a flight can change quickly and lead to costly delays.

There is good news. Advancements in real-time big data analysis are changing the course of flight as we know it. Imagine if the pilot could augment their decision-making process with “real time business intelligence” — information available in the cockpit that would allow them to make adjustments to their flight patterns. 

onur savas's insight:

Started at Aug 5, 2013. Very simple optimization function! Minimize the cost function, which is a superposition of the quantity of fuel burned, the fuel cost, the time in flight, and other costs including hourly cost rates related to crew, passenger and overhead costs. Milestone deadline is on Sep 25.
