All the Best Parts of Pandas for Data Science

Python Pandas Pythonposted by Spencer Norris October 15, 2018

Pandas has been hailed by many in the data science community as the missing link between Python and analysis, a tool that can be leveraged in order to dramatically reduce overhead in data science projects, increase understandability and speed up workflows. Pandas comes loaded with a wide range of... Read more

TensorLayer for Developing Complex Deep Learning Systems

Pythonposted by Daniel Gutierrez October 4, 2018

This article describes TensorLayer, a modular Python wrapper library for TensorFlow allowing data scientists to streamline the development of complex deep learning systems. TensorLayer was released in September 2016 with a GitHub repo. A descriptive research paper followed in August 2017: TensorLayer: A Versatile Library for Efficient Deep Learning... Read more

Snakes in a Package: Combining Python and R with Reticulate

Python R Tools & Languages Python Rposted by Adnan Fiaz September 18, 2018

When I first started working as a data scientist (or something like it) I was told to program in C++ and Java. Then R came along and it was liberating; my ability to do data analysis increased substantially. As my applications grew in size and complexity, I started to... Read more

Machine Learning with H2O – Part 1

Python Tools & Languagesposted by Shivayogi Biradar September 13, 2018

Big datasets pose computation problems for software such as R and python in addition to implementing basic machine learning algorithms that can seem like it would run forever. Most of the time it is difficult to even determine how much time it would take to run these algorithms. Enter H20,... Read more

Building SAGA optimization for Dask Arrays

Python Tools & Languagesposted by Matthew Rocklin August 20, 2018

This work is supported by ETH Zurich, Anaconda Inc, and the Berkeley Institute for Data Science At a recent Scikit-learn/Scikit-image/Dask sprint at BIDS, Fabian Pedregosa (a machine learning researcher and Scikit-learn developer) and Matthew Rocklin (Dask core developer) sat down together to develop an implementation of the incremental optimization algorithm SAGA on parallel Dask datasets. The... Read more

Python Tools & Languagesposted by Eric Ma August 8, 2018

A new release of pyjanitor is out! Two new features that I have added in include: Concatenating column names into a single column, such that each item is separated by a delimiter. Deconcatenating a column into multiple columns, separating on the basis of a delimiter. Both of these tasks come up... Read more

Detecting Outliers

Python Tools & Languagesposted by Damian Mingle August 2, 2018

In this context, outliers are data observations that are distant from other observations. There are a number of reasons why variability may exist in the data that you are working on during your analysis. Outliers may cause serious problems in your efforts as a Data Scientist. title author date Detecting Outliers... Read more

Pickle Isn’t Slow, It’s a Protocol

Python Tools & Languagesposted by Matthew Rocklin July 30, 2018

This work is supported by Anaconda Inc tl;dr: Pickle isn’t slow, it’s a protocol. Protocols are important for ecosystems. A recent Dask issue showed that using Dask with PyTorch was slow because sending PyTorch models between Dask workers took a long time (Dask GitHub issue). This turned out to be because... Read more
