    "Understanding Deep Learning Requires Rethinking Generalization" paper shows how neural networks can memorize even random labels

    Assuimg you reduce in a random manner, I can only assume that the noisy is made by a model to throw off other models (GAMs by Ian Goodfellow)
    hey i just read quickly about machine learning course needed, there were discounts at udemy, i just registered myself : https://www.udemy.com/machinelearning/learn/v4/overview
    its limited time

    Just dropping in a hello in case I sleep and miss the chat again.

    Sorry I couldn't make it Friday night guys, I was at the Machine Learning in Finance conference
    Feel free to read through my notes and if you have any questions, let me know.
    The Goldman Sachs Senior Data scientists I talked to was a really cool guy

    Great story about how he went from sleeping in his car, to winning data hackathons in San Fran, to working at GS

    Hi, I want to classify a multi labeled data using deep learning techniques like CNN without building multiple classifier for each label.. when I read about it they say that I should use multiple sigmoid units on the last layer with binary cross entropy loss function.. actually I didn't understand why this would work and is there a better way to do this?

    Hey Guys
    I'm availabe for at least the next hour to help out with whatever.
    And if any of you know an easy way to parallelize my R scripts I'd love to hear it. ;)

    @rawan_la_twitter I haven't done a multi labeled data classification with CNN, but I have done it with neural nets in general.
    first step is to change your label data into a binary set
    once you get the data out of a one field with multiple values and into multiple fields with binary values it's much easier
    one sec let me see if I can find an example.
    Like this:
    Is the R way

    @keithaumiller hey buddy...so sorry could not make up for last 2 weeks.. have been travelling and is so hectic at weekends now... hope will be able to make it up from next week..
    Also for n categorical to n binary columns... are we trying to make dummy variables here?
    Hey all!
    Keith Aumiller
    No worries.
    I ended up just using Fork instead of trying to do some complicated multithreading stuff.

    Hey Guys
    I'm going to fire up a cyclops.io video chat
    if anybody cares to join me

    Hello guys can any one shed some light on how to build a chat bot which is domain based like say for example for air lines ticket booking using deep learning
    like what are the steps
    or so /

    Sorry Vamsilnm
    just saw this.
    Natural language processing is the field it is in.
    I haven't built one myself, but this is a good place to start:

    I was trying to make a program for image compression using k means clustering
    Can someone tell me what’s wrong with this code?
    from scipy import misc
    import numpy as np
    from scipy.misc import toimage

    def findc(X,incd) :

    for j in range(0,16384):
        k1 = []
        for i in range(0,16):
    return c

    def findu(X,u):
    for j in range(0,16384):
    for i in range(0,16):

    for i in range(0,16):
    return newc

    incd = np.random.randint(np.size(img,axis=0), size=16)
    incd = img[incd, :]
    incd = incd.reshape((16, 3))

    for _ in range(0,10):

    for j in range(0,16384):
    for i in range(0, 16):
    if (c[j] == i):


    Hello Anyone has implemented K-anonymity with clustering?
    Keith Aumiller
    I've done a lot of clustering work, what do you mean specifically about k-anonymity?
    I want to implement K- anonymity with approach of clustering method.
    This is the algorithm which I have implemented using Java.
