10 Python Image Manipulation Tools

Machine Learning Modeling image manipulation Pythonposted by Parul Pandey May 8, 2020

This article looks at ten Python image manipulation tools. Our world today is full of data and images form a significant part of this data. However, to be put to any use, these images need to be processed. Image processing is thus the process of analyzing... Read more

Deploying a Text Classification Model in Python

Machine Learning Modeling Python Text Classificationposted by Miguel Fernández Zafra April 13, 2020

This article is the last of a series in which I cover the whole process of developing a machine learning project. If you have not read the previous two articles, I strongly encourage you to do it here and here. The project involves the creation of a real-time web application that gathers data... Read more

Local Regression in Python

Data Visualization Modeling Python Tools & Languages Data Visualization logical regression Pythonposted by Allen Downey November 15, 2019

I love data visualization make-overs (like this one I wrote a few months ago), but sometimes the tone can be too negative (like this one I wrote a few months ago). Sarah Leo, a data journalist at The Economist, has found the perfect solution: re-making your own... Read more

Timing the Same Algorithm in R, Python, and C++

Python R Tools & Languages C++Python Rposted by John Mount September 23, 2019

While developing the RcppDynProg R package I took a little extra time to port the core algorithm from C++ to both R and Python. This means I can time the exact same algorithm implemented nearly identically in each of these three languages. So I can extract some comparative “apples to apples” timings. Please read... Read more

Building a Data Pipeline in Python – Part 2 of N – Data Exploration

Python Tools & Languages data pipeline Pythonposted by Scott Stoltzman September 6, 2019

Initial data acquisition and data analysis In order to get an idea of what our data looks like, we need to look at it! The Jupyter Notebook, embedded below, will show steps to load your data into Python and find some basic statistics to use them... Read more

Image Augmentation for Convolutional Neural Networks

Machine Learning Modeling Python Convolutional Neural Networks Machine Learning Pythonposted by Nathaniel Jermain June 26, 2019

Limited data is a major obstacle in applying deep learning models like convolutional neural networks. Often, imbalanced classes can be an additional hindrance; while there may be sufficient data for some classes, equally important, but undersampled classes will suffer from poor class-specific accuracy. This phenomenon is... Read more

Jupyter Notebook: Python or R—Or Both?

Python R Tools & Languages Python Rposted by Steve Miller June 13, 2019

I was analytically betwixt and between a few weeks ago. Most of my Jupyter Notebook work is done in either Python or R. Indeed, I like to self-demonstrate the power of each platform by recoding R work in Python and vice-versa. I must have a dozen... Read more
