  • Optimizing item display on graphical user interfaces

    Angemeldet am US US20190171689A1

    A search computing system receives an interaction history for one or more respective users describing interactions with one or more items and generates a co-interaction matrix, each value in the co-interaction matrix representing a number of common users determined to have had the interaction with an item of a corresponding row and an item of the corresponding column of the co-interaction matrix where the value is located. The search computing system generates an embeddings matrix comprising an…

    A search computing system receives an interaction history for one or more respective users describing interactions with one or more items and generates a co-interaction matrix, each value in the co-interaction matrix representing a number of common users determined to have had the interaction with an item of a corresponding row and an item of the corresponding column of the co-interaction matrix where the value is located. The search computing system generates an embeddings matrix comprising an item embedding value for each of the one or more items by applying matrix factorization to the co-interaction matrix and determines, in response to a search query of a particular user, a user embedding value for the searching user based on the interaction history for the searching user. The search computing system determines a similarity between each search result and user interaction history by comparing the user embedding value against each of the item embedding values.

    We've built a little robot-car using the power of arduino + raspberry pi and a couple of motors coupled with a bunch of sensors;

    On top of that, we've also built a desktop (and a mobile) client capable of controlling the car remotely (with the ability to automatically avoid obstacles), but also simulate a 'particle filter': a localization algorithm that make it possible to localize the position and orientation of the car even if the sensors are relatively noisy.

    "Someone's trash is someone's treasure" : That's Donativa's moto.
    This project aim to connect individuals to their local charities so they can give-away this jean that don't fit anymore and this now old-fashioned TV.

    We received many awards for that project (Semi-finalist at Microsoft's "Imagine Cup", runner up at the United Nation's "World Summit Youth Award", a large press coverage, radio interviews, ...)

    The project was fully designed and ready for implementation, but we had to stop it since we both were fully focused on our studies at the time.

Auszeichnungen/Preise

  • Winner of CodINSA 2014

    CodINSA

    Our team won CodINSA, which is AI competition between teams representing one of 6 INSA schools.

    This year's challenge was building an AI for a real-time strategy game. We focused on building something simple (flooding the largest portion of the map with units) and it payed out!

  • Winner of Gamerush 2014

    JV@INSA

    We won the 3rd edition of "Gamerush", a competition that consists in building an original game (including graphics and sound) in 24 hours.

    We built "Tropical Dreams", a game where you play a child defending his cherrished sand castle against violent sharks & bears.

    The code and graphics are open-source and can be found on: https://github.com/golgoth/sand-castle

    The game was built in Python, using the pyglet graphics library.

  • Winner of Fhacktory 2013

    Fhacktory

    We won the Fhacktory hackaton (a hackaton sponsored by Github and Amazon among others) with a crawler/scrapper (what I mainly worked on) & a search engine for objects (as opposed to raw HTML documents).

    We had the chance to present our hack on the stage of the "Blend Web Mix" conference.

  • Finalist at CodINSA 2013

    CodINSA
