Teaching machines to recognize faces: a tale of two outcomes

Machine learning used for facial recognition can have both potentially life-saving and privacy-killing consequences. The rise of cheap sensors, more robust data storage, and advances in machine learning have propelled many industries forward - for instance, many sensors used in the automative industry have focused on detecting vehicle malfunctions, maintenance needs, and even the early components of self-driving cars.

Last week Affectiva announced that it had closed a significant round of funding to further develop its emotion and object detection software (powered by machine learning algorithms). The goal here is to recognize the emotions of the occupants and highlight potential dangers (such as drowsiness). There are many likely extensions to this work, including helping computers understand interactions between the passengers.

But truthfully, there is no reason the technology being developed for this product (which is aimed at decreasing vehicular accidents) couldn’t be used in other settings. Perhaps someday this work could be extended to better understanding human emotion and interactions in public spaces, or human reaction to marketing billboards.

Automatically categorizing faces is a capability that has existed for some time. As facial image capture and categorization become more ubiquitous, we see many products that use this capability to make people’s lives easier (i.e., automatically tagging individuals in photos), and I’ve just highlighted a way in which it is likely to make our lives safer. As many stories of technological advancement go however, this story isn’t all rosy. In the same week as we saw increased investment in Affectiva’s research, we also saw how some Chinese start ups are using facial recognition algorithms to racially profile minority groups. Though these two applications are surely not relying on the same underlying models, architecture, or data, there is a sharing of information and acceleration of these techniques in research communities that enable both.

Even though Affectiva specifically states their intention to develop more ethical software, it’s no longer in the realm of science fiction to believe that other less-ethically minded enterprises could very easily have surveillance installed in our private property (i.e., a car) that is able to categorize what groups the humans inside likely belong to and the emotions involved in their interactions. With this, and other advancements in machine learning at the edge, it’s important for us to continue to think very critically about how to ethically commercialize this research.

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.
