A Quick Look at the Reply-to-Retweet Ratio

Twitter users can retweet, like or reply to a tweet. If a tweet from a prominent account gets more replies than retweets then that’s usually Not Good.

Take, for example, this recent tweet from United Airlines. It got three times more replies than retweets. Those replies are not filled with praise, and that ratio was a sign to United’s PR team that they were in trouble, in case it wasn’t already obvious.

Tweet from United Airlines

Which politician sends the worst tweets according to this reply-to-retweet ratio measure? And without wishing to add to Donald Trump’s problems, are things getting worse for him?

We scraped1 this information from the accounts belonging to Donald Trump, Hillary Clinton, Bernie Sanders, Paul Ryan, and weird Twitter favorites Mike Huckabee and dril. Explore the visualization below.

Things are getting worse for Donald Trump since his inauguration, but it’s clear that Paul Ryan is by far the worst tweeter in this group. Here’s the worst of his tweets, which received 27 times more replies than retweets.

For a more detailed explanation of this dataset, check out the write up on New York Magazine’s Select All technology blog.

1. We wrote ugly scraping code to collect this information because the official Twitter API does not return reply count. You can see the code (and use it to download information for another account) on GitHub. Our visualization shows tweets since January 2016 that received more than 50 retweets.

Implementing CycleGAN
by Michael Gallaspy · Introduction This post documents the first part of a research effort to quantify the impact of synthetic data augmentation in training a deep learning model for detecting manufacturing defects on steel surfaces. We chose to generate synthetic data using CycleGAN,1 an architecture involving several networks that jointly learn a mapping between two image domains from unpaired examples (I’ll elaborate below). Research from recent years has demonstrated improvement on tasks like defect detection2 and image segmentation3 by augmenting real image data sets with synthetic data, since deep learning algorithms require massive amounts of data, and data collection can easily become a bottleneck.

Thought experiment: Human-centric machine learning for comic book creation
by Michael Gallaspy · This post has a companion piece: Ethics Sheet for AI-assisted Comic Book Art Generation I want to make a comic book. Actually, I want to make tools for making comic books. See, the problem is, I can’t draw too good. I mean, I’m working on it. Check out these self portraits drawn 6 months apart: Left: “Sad Face”. February 2022. Right: “Eyyyy”. August 2022. But I have a long way to go until my illustrations would be considered professional quality, notwithstanding the time it would take me to develop the many other skills needed for making comic books.

Text Style Transfer

The NLP task of text style transfer (TST) aims to automatically control the style attributes of a piece of text while preserving the content, which is an important consideration for making NLP more user-centric. In this report, we explore text style transfer through an applied use case — neutralizing subjectivity bias in free text. Along the way, we describe our sequence-to-sequence modeling approach leveraging HuggingFace Transformers, and present a set of custom, reference-free evaluation metrics for quantifying model performance. Finally, we conclude with a discussion of ethics centered around our prototype: Exploring Intelligent Writing Assistance.

Inferring Concept Drift Without Labeled Data

Concept drift occurs when the statistical properties of a target domain change overtime causing model performance to degrade. Drift detection is generally achieved by monitoring a performance metric of interest and triggering a retraining pipeline when that metric falls below some designated threshold. However, this approach assumes ample labeled data is available at prediction time - an unrealistic constraint for many production systems. In this report, we explore various approaches for dealing with concept drift when labeled data is not readily accessible.

Session-based Recommender Systems

Being able to recommend an item of interest to a user (based on their past preferences) is a highly relevant problem in practice. A key trend over the past few years has been session-based recommendation algorithms that provide recommendations solely based on a user’s interactions in an ongoing session, and which do not require the existence of user profiles or their entire historical preferences. This report explores a simple, yet powerful, NLP-based approach (word2vec) to recommend a next item to a user. While NLP-based approaches are generally employed for linguistic tasks, here we exploit them to learn the structure induced by a user’s behavior or an item’s nature.

Few-Shot Text Classification

Text classification can be used for sentiment analysis, topic assignment, document identification, article recommendation, and more. While dozens of techniques now exist for this fundamental task, many of them require massive amounts of labeled data in order to be useful. Collecting annotations for your use case is typically one of the most costly parts of any machine learning application. In this report, we explore how latent text embeddings can be used with few (or even zero) training examples and provide insights into best practices for implementing this method.
