  • Keynote - Come for the Language; Stay for the Community

    by Naomi Ceder

    Buy Tickets Here

    "How you can become involved in the wider Python Community, and why you would want to."

    This talk will focus on involvement in the Python community and what that means - in particular the many personal, social, and professional benefits that flow from involvement in a community like ours.

    I will also explain what the Python Software Foundation does, what its goals and purpose are, and how we have changed the PSF so that everyone in the community can take part to help build an even better Python community. This will include specific explanations of the new membership model and how active contributors (both in terms of code and community organisation) can become full voting members of the PSF.

    I will also touch on our strengths, like our commitment to safe and inclusive spaces and our devotion to education, and also look at some of the challenges we face as a community going forward.

  • Test Driven Documentation

    by Nicolas Laurance

    Buy Tickets Here

    While you write user acceptance tests you describe the way you want the application to behave.
    Writing the documentation is explaining how the application behaves so as to learn how to use it.
    What if from good requirements we could infer part of the documentation ?

  • Using MongoDB and Python for data analysis pipelines (PyData)

    by Eoin Brazil

    Buy Tickets Here

    MongoDB is a flexible, scalable, and ease to use way of storing your large data set. Python provides many useful data science tools (e.g. NumPy, SciPy, Scikit-learn, etc.). Unfortunately, they don't work well together, one of the bottlenecks is the inefficiency of loading MongoDB data into NumPy array.

    This talk will discuss the concerns for creating operational data analytic pipelines, introduce Monary as alternative for loading data into NumPy, and give examples of accessing data with Monary, as well as how to build scalable data analysis pipelines using these open source tools.

  • Workshop: Introduction to Deep Learning (PyData)

    by Bargava Raman Subramanian

    Objective:
    --------------
    In fields like computer vision, speech recognition and natural language processing, deep learning has produced state-of-art results. And they are showing lot of promise in other fields too.

    This workshop will provide an introduction to deep learning. It would cover some of the common deep learning architectures, advantages and concerns through a lot of hands-on.

    Description:
    -----------------
    The workshop will cover the following:

    1) What is deep learning?
    2) Motivation: Some use cases where it has produced state-of-art results
    3 Building blocks of Artificial Neural Networks
    3) Supervised learning (multi-layer perceptron, deep convolution networks, recurrent neural networks )
    4) Unsupervised learning (autoencoders) time permitting
    5) Impact of GPUs (Some practical thoughts on hardware and software)
    6) Hands-on modeling : a text classification problem. Image classification problem would be covered depending on time.

    The data and software requirements are posted onto the github repository. The repository for this workshop:
    https://github.com/rouseguy/intr...

    Please install them prior to the workshop.

    FAQs
    --------
    A) What should be the ideal background of the attendee?
    Ideally, participants should've read up about the following things about machine learning:
    1) What is machine learning
    2) Supervised and unsupervised learning
    3) What is bias and variance
    4) cross-validation
    5) Should have some Python experience to follow the hands-on.

    B) Do I need GPU? All the codes are meant to run on a 4 GB RAM machine. The workshop assumes no GPU on the attendee's laptop. If there's stable internet in the workshop room, we would use www.terminal.com to do the GPU part of the code.

    C) Do you support Windows machine? We haven't used Windows in a while and so, would prefer Linux/Mac. If you have a Windows machine, we strongly recommend you to install a Linux VM and follow the instructions on the repo to install the requirements.

    D) Do I need to know Python? The workshop assumes the attendee has atleast a limited working knowledge of Python. The attendee should've had programming experience(in some language).

  • An introduction to machine learning on small scale datasets (PyData)

    by Conor Lynch

    Buy Tickets Here

    An introduction to machine learning on small scale datasets – identifying Irish farmers who plant forests on their farms.

    The purpose of this talk is to illustrate the differences between explanatory modelling (classical statistics) and predictive modelling (machine learning) as these two approaches are often conflated. The scikit-learn machine learning library was used to classify Irish farmers who planted forests on their land. The dataset was relatively small providing data on 799 Irish farmers and approximately 135 different variables. Prior to classifying farmers, irrelevant and redundant variables were removed from the dataset using a feature wrapper technique which improves the predictive power of models. This illustrates the power of machine learning for inductive analysis by uncovering previously unknown relationships between variables (features). As the Ipython notebooks were computationally demanding the final code was run on gaia, a high performance computer within UCD using runipy. Earlier versions of the Ipython notebooks were run on Amazon EC2 using StarCluster which makes high performance computing available to the general public at reasonable cost.

  • Decorators: Not that scary afterall

    by Paul James Barry

    Buy Tickets Here

    We all use existing decorators all the time (athough Python 3.5 is overloading the @ symbol, which will likely confuse a lot of us ol' timers). However, writing a decorator ourselves can sometimes be daunting. This talk/tutorial walks through an example case study which demonstrates when to create a decorator (and why), and proves - all being well - that decorators aren't all that scary afterall.

  • Probabilistic programming with Lea (PyData)

    by Pierre Denis

    Buy Tickets Here

    The talk aims at introducing Lea, an open-source Python library dedicated to probabilities and probabilistic programming (PP).

    The main concepts of Lea and PP shall be presented. The basic idea is to model some uncertain reality and to make queries on this model. Many simple examples (coins, dice, ...) shall be presented, covering probability distributions, conditional probabilities and Bayesian reasoning. The talk shall also introduce Leapp, a basic PPL that extends Python syntax to ease the usage of Lea.

    If time allows it (50 min), some part of Lea implementation shall be sketched; the original ""statue"" algorithm based on Python's generators shall be presented.

    As prerequisites, only basic knowledge of probabilities is required (no obscure maths!). One of the goal of Lea is to be easy to use, by hiding as much as possible the complexity of probability theory.The talk is meant to follow this principle.

  • Workshop - Modern optimization methods in Python

    by Mike McKerns

    "DESCRIPTION:
    Highly-constrained, large-dimensional, and non-linear optimizations are found at the root of most of today’s forefront problems in statistics, quantitative finance, risk, operations research, materials design, and other predictive sciences. Tools for optimization, however, have not changed much in the past 40 years -- until very recently. The abundance of parallel computing resources has stimulated a shift away from using reduced models to solve statistical and predictive problems, and toward more direct methods for solving high-dimensional nonlinear optimization problems.

    This tutorial will introduce modern tools for solving optimization problems -- beginning with traditional methods, and extending to solving high-dimensional non-convex optimization problems with highly nonlinear constraints. We will start by introducing the cost function, and it’s use in local and global optimization. We will then address how to monitor and diagnose your optimization convergence and results, tune your optimizer, and utilize compound termination conditions. This tutorial will discuss building and applying box constraints, penalty functions, and symbolic constraints. We will then demonstrate methods to efficiently reduce search space through the use of robust optimization constraints. Real-world inverse problems can be expensive, thus we will show how to enable your optimization to seamlessly leverage parallel computing. Large-scale optimizations also can greatly benefit from efficient solver restarts and the saving of state. This tutorial will cover using asynchronous computing for results caching and archiving, dynamic real-time optimization, and dimensional reduction. Next we will discuss new optimization methods that leverage parallel computing to perform blazingly-fast global optimizations and n-dimensional global searches. Finally, we will close with applications of global optimization in statistics and quantitative finance.

    The audience need not be an expert in optimization, but should have interest in solving hard real-world optimization problems. We will begin with a walk through some introductory optimizations, learning how to build confidence in understanding your results. By the end of the tutorial, participants will have working knowledge of how to use modern constrained optimization tools, how to enable their solvers to leverage high-performance parallel computing, and how to utilize legacy data and surrogate models in statistical and predictive risk modeling.

  • Keynote: Creating safe learning experiences for all of our community members.

    by Juliana Arrighi

    Many of us have been drawn to the Python community because it has welcomed us warmly and has shown us many high quality learning resources. We can further develop this aspect of our community by being aware of the potential barriers to learning when contributing new informational resources like conference talks, tutorials, documentation, or even just conversations at community events. This is especially important if you're interested in engaging people who are different than you.

    Any time we are faced with the need to learn a new skill, we may experience a variety of emotional responses ranging from energised interest, a bit of frustration, or even extreme intimidation. It can be even harder to learn successfully when you don't feel welcome in learning communities or when available resources don't cater to your level of experience. You can make learning more accessible for your audience by considering the different thinking styles, backgrounds, and the contexts in which learners are seeking information.

    In the first part of this talk, I'll give some reasons you might want to put some extra effort into addressing the diversity of your audience. Then I'll outline some ways I've found to help make learning more accessible and less intimidating for different types of learners.
