Machine Learning in Python with scikit-learn

  • Mar 7, 2013 · 6:30 PM
  • This location is shown only to members

Possibly one of the best open source machine learning projects around.

scikit-learn http://scikit-learn.org/stable/ is a well established Open Source machine learning library mostly written in Python with the help of NumPy, SciPy and Cython.

scikit-learn is very user-friendly designed with a simple and consistent API and extensive documentation. Strictly enforced coding standards and high test coverage guarantee high quality implementations. Behind Scikit-learn is a very active community, steadily improving the library.

Come and meet Olivier & Andreas, two smart hackers-by-night who are main contributors to the project.

7pm talks start

Section 1

“Learning in Python with scikit-learn" by Andreas Mueller

This talk will give an overview of the library and introduce general machine learning concepts such as supervised and unsupervised learning, feature extraction, cross validation for model evaluation and hyper parameter selection. We will also touch some more advanced yet practically useful concepts such as feature hashing and ensemble learning.

Andreas is a PhD student in machine learning an computer vision at Bonn University (Germany). He is one of the core developers and the maintainer of scikit-learn and the author of the blog peekaboo-vision. His interests include principles and applications of machine learning and open science.

Beer break, Networking and Community Update

Section 2

"Parallel and large scale learning with scikit-learn" by Olivier Grisel

This talk will give a introduce practical tools and concepts to better leverage multicore machines and small clusters to perform interactive yet scalable predictive modeling with scikit-learn and IPython.parallel. In particular we will introduce:

  • A short introduction to the parallel features of IPython from thenotebook interface
  • How to perform scalable text feature extraction with the Hashing Trick
  • How to parallelize or distribute model evaluation (cross validation) and hyper parameters tuning
  • How to optimize memory usage with memory mapping
  • How to approximate kernel Support Vector Machines for large scale datasets
  • A short introduction to Ensembles with model averaging and Random Forests

Olivier is a R&D Software Engineer working in Java by day and a Python machine learning hacker by night. He is interested in applications to Natural Language Processing, Computer Vision and predictive modelling in general

 

More beer + networking

9.30pm-ish meetup ends

    Will there be any slides/video recordings? Content sounds great, wish I'd seen it yesterday ;)

    Very good presentations. Glad I arrived early and got a seat!

    March 8, 2013

  • Mark B.

    Very good talks, and plenty of refreshments. In fact the only problem with the evening was the popularity of the subject...with so many people there it meant some had to sit on the floor, which was fine (better that, than being turned away), but it did mean that you couldn't see the screen. Still, popularity is a good problem to have.

    Sorry I can't make it as I've been in the waiting list and just received the email at 18:15, confirming I can attend. It is too late for meeting starts in 15 mins.

    Last minute work commitments prevent me from going to this :( I was so looking forward to it...

    Sorry Guys - ended up making other plans. Will free this spot up for others.

    Sorry. Illness in family means I can no longer make it. Please ensure that slidea are uploaded somewhere though!

    Sick :(

  • James P.

    Please start charging a nominal fee! These meetups fill up ridiculously quickly.

    How likely is it to get in from waiting list? This sounds like a really interesting session.

    Thanks

      Hi William, at the session I went to, they took attendance on the door. But I understand it's rare for these free meetup events to get 100% attendance.

      March 5, 2013

    • Geoff H.

      You could well have introduced non-linearity into the attendance numbers. Like the bar in Santa Fe playing music. If people thought there was a chance of getting in they'd all go, and it would be too crowded. If they thought it was going to be busy, they'd all stay away and it ended up empty.

      March 6, 2013

  • W.

    Sounds good would love to come. How likely is it I'll be let in even though I'm on the waiting list?

    March 4, 2013

    meeting clash :(

    I went to the prof Brian coz meet up which was very overly subscribed the solution used was to use the adjoining rooms as split over rooms with a live video link up, just an idea!

    March 1, 2013

  • Eriza F.

    Hi Carlos, sorry I have to cancel my attendance due to a business trip request at a short notice. One spot free for those in the waiting list. Sorry again.

  • Klaudia G.

    Carlos, why is there so much concern for beer and pizza? To be honest I'm happy to not get anything to eat or drink AND sit on the floor or stand up for the entire session just as long as I can be there.
    Shouldn't an opportunity to be there be of the highest priority? Surely, those who truly come for knowledge won't find lack of free refreshments a problem!

    2 · February 26, 2013

    • Ian O.

      @Klaudia - the room is full (and the beer/pizza runs out if you're not there early). It is simply the case that the event is very very popular!

    • Sergey K.

      When i joined waitlist it was 120 attendants, and 40 on the waitlist. Now there are some 180 people going, i'm still on the waitlist. Guys, i don't drink/eat that much)))

      February 26, 2013

  • Christina

    Hope a spot gets available. ..

    February 25, 2013

  • Danny T.

    on waiting list, again?! Spots get filled up probably as soon as the event's announced! :(
