PyData Tel Aviv Meetup #22 3 April 2019 Sponsored and Hosted by SimilarWeb https://www.meetup.com/PyData-Tel-Aviv/ Labeled data containing incorrect labels, termed label noise, has gained much attention in machine learning research due to its adverse impact on supervised models. This effort has increased in recent years, as the usage of larger data sets, which are more prone to label noise, has become prevalent. To tackle this problem, studies have explored the sensitivity of the learning process to label noise and devised robust methodologies to overcome it. This talk covers basic concepts in label noise research and explores suggested approaches for overcoming its negative effects. It also showcases two practical examples of easy-to-use methods which were tested on training sets contaminated by label noise and by target value noise. www.pydata.org PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States.

PyData Warsaw 2018 It is commonly accepted that about 80% of data scientists time is spent on preparing data, including setting up the proper data pipeline or ETL. For a large part, the proper configuration of a given data pipeline is the result of the data scientist experience and Subject Matter Expert knowledge, plus a dose of arbitrary decisions. What if most of this work could be automated? Better, is it possible to find some universal pipeline configurations that can work well on a wide range of domains and thus transfer what has been learn on one dataset to another? In this presentation, we show on a PoC that Sequential Model-Based Optimization techniques can be used to tune data pipeline hyperparameters in order to improve model accuracy. We discuss how to measure if optimal configurations are algorithm-specific or independent, shows that, in the specific case of NLP preprocessing operators, there might exist some kind of generally good configurations, independently of th...

PyData Miami Meetup - March 5, 2019 https://www.meetup.com/Miami-Machine-... While GPUs have been instrumental in the deep learning revolution since 2012, smartphones can also run deep neural networks on their own hardware and exceed state-of-the-art image classification performance from just a few years ago. This is mostly due to advances in neural network design and model structures. Innovations like the depth-wise separable convolution, for example, have enabled more efficient computation in neural nets. Hardware has also advanced in terms of compute and memory capacity. Put together, a smartphone today can quickly classify images with a lightweight neural network with a higher accuracy than AlexNet achieved in 2012. ---- William Grisaitis is a machine learning engineer and curious person based in Orlando, Florida.

Project Jupyter aims to provide a consistent set of tools for data science workflows, from the exploratory phase of the analysis to the sharing of the results. Maarten Breddels and Sylvain Corlay offer an overview of Jupyter’s interactive widgets framework, which enables rich user interaction, including 2D and 3D interactive plotting, geographic data visualization, and much more, as well as the main interactive visualization libraries that were built upon it. More than a set of controls, Jupyter widgets are a framework upon which one can build. Just as the kernel protocol is agnostic to the programming language, Jupyter widgets enable bidirectional communication between the web browser and the kernel in a language-agnostic fashion. Beyond the Python reference implementation, C++, R, and JVM languages (Java, Clojure, Scala, Kotlin, and Groovy) have joined this exciting development, allowing users to reuse all the frontend code.

Originally aired June 24, 2014. In this webcast you will learn how Python can be used for Derivatives Analytics and Financial Engineering. Dr. Yves J. Hilpisch will begin by covering the necessary background information, theoretical foundations and numerical tools to implement a market-based valuation of stock index options. The approach is a practical one in that all-important aspects are illustrated by a set of self-contained Python scripts. This webcast talk will cover: Financial Algorithm Implementation Monte Carlo Valuation Binomial Option Pricing Performance Libraries Dynamic Compiling Parallel Code Execution DX Analytics Overview and Philosophy Multi-Risk Derivatives Pricing Global Valuation Web Technologies for Derivative Analytics About Yves Hilpisch Yves Hilpisch has 10 years of experience with Python, particularly in the finance space.

In this hands-on webcast presented by Harry Percival author of Test-Driven Development with Python, you will learn: How to use TDD to build a web application from the ground up Full functional testing using the Selenium browser automation tool Unit tests for all aspects of Django: urls views models templates Who should attend this event: This live webcast is suitable for relative beginners, you should know basic Python, but if you've never used TDD or Django you should be fine. About Harry Percival After an idyllic childhood spent playing with BASIC on French 8-bit computers like the Thomson T-07 whose keys go "boop" when you press them, Harry spent a few years being deeply unhappy with Economics and management consultancy. Soon he rediscovered his true geek nature, and was lucky enough to fall in with a bunch of XP fanatics, working on the pioneering but sadly defunct Resolver One spreadsheet. He now works at PythonAn...

Are you using Python to process large numerical datasets? Over the past few years, the Hierarchical Data Format (HDF5) has emerged as the mechanism of choice for processing, archiving and sharing scientific datasets ranging from gigabytes to terabytes and beyond. With a diverse user base spanning the range from NASA to the financial industry, HDF5 lets you create high-performance, portable, self-describing containers for your data. HDF5's flexibility and speed make it particularly well-suited to analysis in Python. This webcast provides a practical, Python-based introduction to the world of HDF5. This webcast led by Andrew Collette will cover: - The basics of the format - Performance - Best practices for making sharable data files which can be read by colleagues on other platforms About Andrew Collette Andrew Collette holds a Ph.D. in physics from UCLA, and works as a laboratory research scientist at the University of Colorado. He has worked with the Python-NumPy-HDF5 st...
