Flight Quest Phase 1 Winners

  1. 1st Prize: Team Gxav &*

    Xavier Conort, Cao Hong, Clifton Phua, Ghim-Eng Yap and Kenny Chua (Singapore)

    Team Gxav &* used a mixture of gradient boosting and random forest models to predict gate and runway arrival times. With average errors of 4.2 and 3.2 minutes for gate and runway arrivals, respectively, this translates to 40% and 45% improvements over the standard industry benchmark estimates. Key to their success was careful feature selection with their final models using only 58 and 84 features for gate and runway arrivals, respectively, from the total 258 features they painstakingly constructed and optimized.

  2. 2nd Prize: Team As High As Honor

    Jonathan Peters (Preston, UK) and Paweł Jankiewicz (Warsaw, Poland)

    Team As High As Honor used a two-step approach that combined the results of a generalized linear model that encoded intuition about important variables with refinements derived from a random forest model. The team capitalized on the success of the linear model to add the effects of multiple variables and cleanly resolve issues of missing data.

    • Jonathan is an Epidemiologist, specifically a Public Health Analyst and Data Modeler with a particular interest in machine learning. His work for Trilogy SmartLeads involves creating and refining models to predict the probability that an internet automotive lead will convert to a sale.
    • Paweł is Reporting & Analysis Team Leader at Raiffeisen Polbank and earned a Masters in Investment Banking from the Warsaw School of Economics. Paweł is 29 years old and has 5 years of experience in the banking industry as a reporting specialist. He began learning programming as a hobby 5 years ago and is currently proficient in Python, R and SQL. He loves competing on Kaggle in his free time (if any). After succeeding in the Flight Quest competition he decided to quit his job in a bank to spend more time on data mining projects. Website »
  3. 3rd Prize: Team Taki

    Gabor Takacs(Gyor, Hungary)

    Team Taki used a six layer model relying on successive ridge regressions and gradient boosting machines to model both gate and runway arrival times. This approach used 56 features extracted from the raw data, with all but two coming from the test day data.

    • Gabor is an Assistant Professor at Szechenyi University, a small university in Hungary and part-time consultant at Gravity R&D, a recommender system company. He was the captain of The Ensemble team that finished second in the Netflix Prize competition. Gabor received an MSc in Informatics and PhD in machine learning from the Budapest University of Technology and Economics. His main research interests are machine learning and artificial intelligence. Website »
  4. 4th Prize: Team Sun

    Sergey Kozub (Kursk, Russia)

    Team Sun’s approach to predicting gate and runway arrival times relied on creating a derived data set with new variables encoding information about the aircraft, airport, airway, gate, hour, and flight path times. Important features used in this model include aircraft GPS position, ASDI flight plans and the direction from which airplanes approached airport runways.

    • Sergey Kozub is an IT developer in financial applications with an MSc in Computers and Networking from Technical University of Moldova.
  5. 5th Prize: Team Jacques Kvam

    Jacques Kvam (Livermore, CA, USA)

    Jacques Kvam’s approach for predicting runway and gate arrival times used gradient boosting for a model using 10,000 trees and a whopping 1,102 features trained on 260,000 flights. Most significant among these included the distance between the final waypoint and the arrival airport. Many weather features were important as well including temporary vertical visibility and wind speed at the arrival airport.

    • Jacques Kvam is an electronics engineer with an MS in EE from UW-Madison.
  6. Honorable Mention: Team __mtb__

    Matt Berseth (Jacksonville, FL, USA)

    Team __mtb__ used random forest and gradient boosted models to estimate runway and gate arrival times. The final solution included over 100 different individual models, each focused on a narrow set of features (i.e. wind/weather, flight plan, aircraft's current location, etc.). These individual models were blended together to generate the final estimates. The training data was created by randomly selecting eight cutoff times for each day in the training period. A separate cross validation data set was used to select hyper-parameters.

    • Matt Berseth is co-founder and lead data scientist at NLP Logix, technology company based in Jacksonville, FL. Before NLP Logix, Matt created software solutions in a variety of different industries including healthcare, marketing and supply chain / logistics. Matt was first introduced to machine learning while earning his bachelors and masters degrees from North Dakota State University (go Bison!). His favorite modeling techniques include boosting and neural networks.
