For that reason, we wanted to supply as unfiltered data as possible.</p>\n<p>We don't expect you to be able to reconstruct \"un-reconstructable\" events, but your model must be able to deal with those. There are several ways to achieve that, the von Mises Fisher loss being but one example (The distribution has an additional parameter kappa that encodes the uncertainty of the reco, which the NN can predict to be very large for un-reconstrutable events). Another option would be first to clean the dataset before training, such that your NN can really home in on the good events. Then when applying it to junk it will spit out more or less random numbers, which is ok.</p>\n<p>The test set is quite large with 1e6 events, such that the performance on the junk data will average out and really the performance on the good data will drive your score.</p>\n<p>The comment made by <a href=\"https://www.kaggle.com/alexz0\" target=\"_blank\">@alexz0</a> is also correct, we would like to be able to run the reco as early as possible in the processing chain. The rate of events like those in the training set + even more \"junk\" is around 2.7 kHz, which is what is actually read out from the detector and being processed. ideally, we would apply the reco to all those events.</p>",

    "1958559": "Dear Kagglers,\n\nWelcome to the IceCube neutrino challenge!\n\nNeutrinos allow us to gain deep insights into the fundamental structure of matter, and to research our universe uncovering cataclysmic phenomena far away from our Earth. At the South Pole, in the middle of the Antarctica ice, we have constructed the world's largest neutrino detector and are taking data for more than 10 years. Interpreting this data, and in particular figuring out where exactly neutrinos came from, especially in a timely manner for real-time observations, is a daunting task. This is where we need your help! Your task is to estimate the direction of neutrinos that interacted in IceCube and provide fast and accurate predictions for the zenith and azimuth angles per recorded event.\n\nWe hope that you take up the challenge and that maybe together with your ideas and algorithms we will be able to unravel some scientific mysteries in the future!\n\nPlease enjoy, have fun, thank you, and the best of luck!\nPhilipp Eller on behalf of the organizing team\n\n**The webinar recording is now available [here](https://www.youtube.com/watch?v=_G4Nx20BVPg) and a pdf of the slides is attached to this post.**",
    "2107690": "Thanks for the exciting competition. I have a question for both `train` and `test` is this real data or simulated or a mix of both? ",
    "2114364": "what kind or error do you get in your current algorithm? I assume you tested it against this type of data. This would give us something to aim for.",
    "2110463": "Thank you for organizing this interesting competition! Three questions,\n1. what is the energy distribution of the neutrinos in the data? When searching for papers about neutrino observation, I noticed that neutrinos interact differently with matter depending on their energy, and I am assuming that this information would help us a lot.\n2. would you mind to provide us more information about the IceCube simulator? A link to the document would be grateful.\n3. Are there any events in which more than one neutrino is associated, or in which signals from particles other than neutrinos appear?",
    "2116853": "Thanks for hosting a great webinar today.  I am looking forward to the viewing the recording, do you know when it will be available ?",
    "2119293": "why so much data? It appears that results are very stable across batches, so CV over 1 batch would be almost the same as CV over all batches. So why give us > 100 Gg? Most competitors would not be able to use all of it anyway, due to RAM limits. So, what was the point?",
    "2184471": "This small PDF should be made bigger and should be given a first priority over all the listed resources about neutrinos. As it talks about the approach to solve the problem. And thanks for sharing.\n\nWhat's the surface area for the neutrinos to enter into the ice cube? Is it from all directions or just the head part of the ice cube?\n\nIs ice cube half empty, just the bottom part contains the sensors? [1450m-2540m]? Why half n half?\n\nLet's talk about simplicity as it beats complexity, for a given line what will be the same at start point and at the last point? time? as its faster comparable to speed of light?",

    "2116805": "Thank you, for the wonderful seminar!!\n\nI had to drop halfway, and am 100% looking forward to reviewing the recording.\n\nI can’t wait to dive deeper and see what I can bring to this competition. Thanks again! ",
    "2108807": "Hi. mind to provide the event id / code used for the exemple image in the data tab ? most of the event do not seem to have such correlations between observed (auxiliary = False) and the target path. ",
    "2216950": "Hello \nI have been trying to submit my notebook for a long time, but every time my notebook gets submitted without error, I get a Submission scoring error. I checked my submission format 10 times but still got samesame error. I did index = False, have an equal number of rows demanded, and my values are in the accepted range. I am not getting where my submission is wrong. If you can help with that, it will be of great help. \nLink to one of my submission: https://www.kaggle.com/code/rohitmalawat/neutrinoicecube?scriptVersionId=118860061",
    "2189298": "If I somehow manage to get in the top ranks and write a paper I will vent on this topic  for multiple paragraphs.\n\nThe notion that machine learning can make sense of junk is pretty common in today's world.  The data set seems to be built with that idea.\n\nThere is a minimum of 20% junk events.  I am pretty sure it's junk.  I am pretty sure with your current filter's it never leaves the South Pole.  Two or three lines of Python sufficient to determine it's a junk event and discard it.  A pretty decent number of my models parameters are attempting to make sense of it but they never will - they can only eventually arrive at the junk average.  \n\nI can't of course discard it and improve accuracy of the events to keep because my LB score will suck.  \n\nThat being said - it's a very interesting challenge.  ",
    "2171880": "Thanks for the exciting competition! In the recording above, you said that the data is simulated and the flavour of neutrino that caused these events is mixed. So, the flavour of neutrino that caused these events completely random?",

    "2155838": "Hello @pellerphys, would it be feasible to incorporate a feature that allows us to view the recorded time for running the hidden test dataset after every submission? This feature would be beneficial in estimating the total running time of the code for the private dataset and can be used to design inference accordingly to prevent any cut-offs due to time constraints for final submissions.",

    "2121026": "sir, what does your 'official experiment simulation' mean? is it a model? or a simulated data? i am not quite understand! thanks! ",
