The Austin ML Journal Club brings together ML/AI practitioners for monthly deep dives into seminal research. We read papers in advance, meet virtually for 90 minutes under Chatham House Rule, and critically examine methodologies, experimental design, and real-world applicability.

AI as Normal Technology

This article challenges both AI doomsday narratives and hype by framing AI as a normal transformative technology comparable to electricity or aviation. Drawing from historical technology adoption patterns, the authors argue for pragmatic policy approaches focused on deployment-level safeguards, sector-specific regulation, and institutional resilience rather than speculative fears about autonomous superintelligence. A refreshing, evidence-based perspective for practitioners tired of extremes.

On the Theoretical Limitations of Embedding-Based Retrieval

This preprint explores theoretical limits of single-vector embeddings through communication complexity theory, proving that embedding dimension bounds the number of representable top-k document combinations. Our discussion focuses on the gap between elegant theory and problematic experiments, embedding truncation, and tasks designed for memory not semantics. An interesting theoretical framework that needs more careful empirical validation.

Modeling Tabular Data using Conditional GAN

Tabular data synthesis (data augmentation) is an under-studied area compared to unstructured data. This paper uses GAN to model unique properties of tabular data such as mixed data types and class imbalance. This technique has many potentials for model improvement and privacy. The technique is currently available under the Synthetic Data Vault library in Python.

Gorilla: Large Language Model Connected with Massive APIs

The power of LLMs, in a commercial setting, comes from its ability to use other tools and integrate business domain knowledge too. Unfotunately, it is still challenging getting the LLMs to work well when hooking up custom APIs that interface with custom processes and data. This paper is interesting, largely because it may be a step forward in getting the LLM to accurately use custom tooling.

Dissecting Racial Bias in an Algorithm Used to Manage the Health of Populations

Amidst the LLM hype, algorithmic bias in a critical domain such as healthcare is continued being overlooked. This algorithm-audit paper found racial bias in a widely used healthcare system and discussed the problem of using a wrong target variable. The paper is a few years old but the message is still relevant, and we discussed what’s happened since then.

Are Emergent Abilities of Large Language Models a Mirage?

Recent research observed that the largest models exhibit incredible increases in performance on a wide variety of tasks compared to smaller models. This paper argues that such so-called emergence is actually more reflective of the evaluation metric used. Switching to metrics that are known to scale smoothly with the per-token error reveals a much more predictable picture.

Direct Preference Optimization: Your Language Model is Secretly a Reward Model

This paper proposes a new technique to align LLMs with human preferences without using RL. This method is more robust and shows better performance over models trained with RLHF.

Why Do Tree-based Models Still Outperform Deep Learning on Typical Tabular Data?

This paper compares the performance of deep learning techniques to traditional tree-based methods for a novel set of 45 tabular datasets. The inductive biases of tree-based versus neural network models was analyzed as a proposed method to guide development of improved tabular specific neural network models.

Neural Machine Translation by Jointly Learning to Align and Translate

This paper marks an important step in the development of machine translation (MT). It came out just as Neural Machine Translation (NMT) was taking off, extending from Statistical Machine Translation (SMT), and as a milestone along the way to Transformer-based NMT. The authors introduce a novel attention mechanism applied to MT and show that it improves performance on long sentences, in particular, from prior recurrent neural network NMT approaches.

Constitutional AI: Harmlessness from AI Feedback

There is an arms race of large language models (LLMs) in industry where companies use different approaches and techniques. Anthropic claims to adopt a more cautious approach that minimizes harm by LLMs than others. Let’s look into constitutional AI, the core algorithm of their LLM, to understand how this harm mitigation works.

AutoKnow: Self-Driving Knowledge Collection for Products of Thousands of Types

In e-commerce, it is challenging to organize and categorize products that are described by merchants in various ways. Finding a unified language and taxonomy has always been an underlying effort with commerce. This paper uses various ML algorithms to address this challenge.

Let’s Verify Step by Step

This is an interesting new paper by OpenAI that discusses how we can apply the same principles we use to solve math problems to AI. The paper evaluates different approaches to solving a dataset comprising of math problems. With this approach, they trained the model to get the right answer and but also “think” through the problem to arrive at the right answer.

Visualization in Bayesian workflow

This paper summarizes types of data visualization that we can use in Bayesian modeling and inference. It also provides a good overview of how to do Bayesian data analysis properly, including model validation such as prior and posterior predictive checks.

Reviwing a Case Study About Real Estate Market Prediction

The paper reviewed here attempts to predict outcomes about the real estate market with binary classification. Though the paper’s research design and results were lacking, it gave us a chance to have a discussion about practices for experimental design.

Leakage and the Reproducibility Crisis in ML-based Science

Data leakage in a common problem in ML-based science leading to reproducibility failures and overly optimistic conclusions. We discussed 8 types of data leakage and the use of model info sheets to identify and reduce all leakage types.

Zero-Shot Text-to-Image Generation

There is so much hype in generative AI. But how does it actually work? We discuss OpenAI’s DALL-E paper to understand model architecture but more importantly, whether their model validation is solid and reasonable.

“Everyone wants to do the model work, not the data work”: Data Cascades in High-Stakes AI

Garbage in, garbage out. It seems like a lot of people in the ML community still don’t understand this logic. We discuss poor data-handling practices and their critical ramifications.
