What We Miss About Missing Values

Missing values are a ubiquitous challenge in data science, yet their implications often go unexamined. "What We Miss About Missing Values" explores the hidden assumptions embedded within the data we *do* observe—recognizing that what's absent can be just as informative as what's present. This post delves into the biases introduced by missingness and offers a framework for more thoughtful analysis.

A Classification model trained entirely on a scientific calculator [P]

This remarkable project demonstrates the surprising potential of constrained AI. A classification model, meticulously trained solely on a Casio FX-82CE X scientific calculator—a non-programmable device—achieved a 67.04% validation accuracy on a binary MNIST dataset. The architecture, utilizing a simple 3x3 pixel input and a single output neuron, initially struggled with "zero" predictions, but reached an impressive 98.96% accuracy after 1000 epochs. For those interested in exploring the nuances of model optimization, our guide, "How to Fine-Tune an LLM: An End-to-End Guide," offers a

Understanding Anti-AI Public Opinion

Public perception of AI is shifting, and understanding the growing anti-AI sentiment is crucial. People readily accept tradeoffs when they perceive clear value, but a lack of perceived benefit can quickly erode trust. This post explores the factors driving this resistance, examining how to build solutions that resonate with user needs and address concerns. Discover how aligning AI capabilities with tangible outcomes can foster broader acceptance—a perspective mirrored in our analysis of RAG pipeline efficiency, as detailed in "Kimi K3’s 1M Token Context Window vs.

How much does adding an honest limitations section hurt the paper? [D]

Addressing limitations honestly in research papers—while generally beneficial—raises critical questions about reviewer bias and potential requests for remediation. Does openly acknowledging constraints negatively impact perception, or will reviewers demand fixes outlined in the limitations section? Furthermore, the introduction of AI reviewers introduces a novel consideration: could these limitations inadvertently bias algorithmic assessment? Exploring these nuances, as discussed in "My Model Was Cheating on Its Own Test," highlights the complexities of transparency in AI research.

Are there any theoretically-guided practices left in machine learning nowadays? [D]

The rise of large language models has sparked a critical question: have theoretically-guided practices in machine learning become relics of the past? Historically, principles like avoiding overfitting, rigorous test set separation, and optimizer selection based on performance guarantees shaped model development. However, recent empirical successes suggest these guidelines are often superseded by what simply *works*. Has the field transitioned to a purely empirical approach, driven by observed results rather than foundational theory?

Why You Shouldn’t Always Trust LLMs as Judges: Understanding Bias in Automated Evaluation

The increasing adoption of Large Language Models (LLMs) for automated evaluation—from assessing code to ranking research—presents a critical challenge. While their speed and scalability are compelling, relying on LLMs as impartial judges demands careful consideration. As highlighted by Bhaskarjit Sarmah at DHS 2026, inherent biases within these models can skew results, undermining the fairness of automated assessments. Explore the nuances of this issue and discover how to navigate this evolving landscape responsibly.

How do you debug a forecasting model today when the error is quite bad?

Encountering unexpectedly poor forecast performance? Diagnosing the root cause goes beyond a single error score. Experienced practitioners systematically investigate discrepancies, often breaking down errors by key dimensions like customer, product, or time horizon. Many routinely build custom notebooks and visualizations to facilitate this analysis—a significant manual effort. We’re exploring common workflows used to pinpoint issues, potentially informing an open-source tool for streamlined forecast evaluation. See "What to consider when creating waterfall charts" for a related perspective on data visualization techniques.

Why Your Best Predictive Model Gives the Wrong Treatment Effect

Even the most accurate predictive models can mislead when estimating treatment effects. Relying solely on prediction-driven variable selection often overlooks crucial confounders, leading to inaccurate conclusions about cause and effect. This stems from prediction models optimizing for accuracy, not causal inference. Bayesian Adjustment for Confounding offers a promising approach to mitigate this, systematically accounting for potential confounders.

Evaluated 6 frontier LLMs (GPT-5.4, Claude Sonnet 4.6, Claude Opus 4.7, Gemini Pro/Flash, Grok 4.3) on political, gender, and racial bias across 8 benchmarks (~20,600 examples) [R]

A recent solo evaluation project rigorously assessed six frontier LLMs—GPT-5.4, Claude Sonnet 4.6, Claude Opus 4.7, Gemini Pro/Flash, and Grok 4.3—across eight established bias benchmarks, encompassing over 20,600 examples. Findings reveal a consistent leftward political leaning among all models except Grok, despite its self-reported right-leaning stance. Notably, GPT-5.4 exhibited the highest refusal rate (20.3%) when addressing race-related inquiries requiring explicit racial identification.
