    "122399": "I also want to know if he used ML method.",
    "122400": "LOL \r\nLet the last week madness begin!",
    "122402": "Awesome",
    "122405": "Magic ML method outperfoming 'counters' or a second leak?\r\nAnyway impressive.",
    "122407": "I think he won this competition already. maybe 1 sub will be enough?:D",
    "122436": "Awesome!   It is fantastic!   0.60443- Well done!",
    "122438": "omg.... It's awesome... Incredible!",
    "122440": "I guess there may be some new leakage that we haven't found.",
    "122443": "I'm in the 2nd leak camp.  I know I've been searching for it, if it exists!",
    "122446": "This is simply awesome @idle_speculation\r\n\r\nAnd thank you for giving the rest of us 1 week time to think what it is, when you could have simply submitted this on the very last day :)",
    "122447": "[quote=SRK;122446]\r\n\r\nAnd thank you for giving the rest of us 1 week time to think what it is, when you could have simply submitted this on the very last day :)\r\n\r\n[/quote]\r\n\r\nThen it wouldn't be a win by one submission",
    "122450": "Hm, it looks like  @Idle_speculation concentrates on user preferences instead of leakage and hotel statistics.",
    "122451": "Grzegorz, what makes you think that?",
    "122453": "Branden, Look at the open script as an example.\r\nThere are three parts:\r\n\r\n1) leakage\r\n\r\ne.g. s1 = (user_location_city, orig_destination_distance)\r\n\r\n2) hotel statistics\r\n\r\ne.g. s2 = (srch_destination_id,hotel_country,hotel_market)\r\n\r\n3) user preferences\r\n\r\ne.g. s01 = (user_id, srch_destination_id, hotel_country, hotel_market)\r\n\r\nNowadays, this part  is really small. It corresponds only to the places where the user was already.",
    "122455": "And do not forget the last part  of the scripts with the top clusters. This part has the lowest hit rate. Perhaps this is the place to concentrate. ..good luck",
    "122457": "Evdilos_Ikaria, this part has the lowest hit rate because almost all 5 places are filled already.",
    "122461": "omg...he is the winner.",
    "122583": "idle_speculation's other winning solution related to ranking\r\nhttps://www.youtube.com/watch?v=7UHOa2JvC9k",
    "122643": "I noticed that idle_speculation is ICDM 2015 championship... O_O",
    "122666": "idle_speculation surprised us by staying idle all along and racing on the last day of 1st submission and finishing 1st",
    "123057": "What does this say about machine learning? One really smart person, with possibly just one smart algorithm can beat the collective, and can do so quite efficiently.",
    "123059": "It says that bagging ensemble of weak learners in not always the best approach :)",
    "123086": "It might be the same algorithms as everyone else was using; they probably just spent much more time on some very good feature engineering.",
    "123118": "Or a different leak :)\r\n\r\nI guess we will all know in a couple of days..."
