I'm pleased to share the preprint of our latest research, submitted to Computational Statistics (Springer Nature), which I co-authored with one colleague. We propose a cross-fitted contamination-aware generalized empirical-Bayes Liu estimator (CF-CABLS-MNL) for multinomial logistic regression. The method integrates robust estimation, empirical-Bayes shrinkage, cross-fitting, and spectral regularization to improve estimation and prediction in the presence of multicollinearity, response misclassification, high-leverage observations, and outliers. Extensive Monte Carlo simulations and repeated analyses on UCI benchmark datasets demonstrate competitive predictive performance and enhanced robustness under simultaneous response and leverage contamination. The results further indicate that response-misclassification correction is beneficial when contamination exists but should not be viewed as universally advantageous.

What does DNA have in common with computer code, hieroglyphics, and a Shakespearean sonnet? They all contain specified information. And according to Dr. Stephen Meyer, specified information has only ever been traced to one source — a mind. Praxis Circle Contributor and NYT bestselling author of Signature in the Cell makes the case that the information encoded in DNA is not random. It’s the strongest scientific evidence for intelligent design we’ve ever found.

Analyzing stripped Commercial Off-The-Shelf (COTS) binaries without debug symbols has long been one of the toughest bottlenecks in advanced software security and binary analysis. Traditional symbolic execution engines hit a wall against state explosion, while fuzzers struggle to systematically uncover deep concurrency flaws. To tackle this, we’ve developed XEGMAP: Adaptive Symbolic Execution for Race Condition Detection in Binary Programs, which has now been officially published as a pre-print on Research Square: 🔗 Read the full pre-print (here: https://lnkd.in/dNgBFf4J ) What makes XEGMAP different? XEGMAP introduces an adaptive, two-phase framework built on top of angr designed to navigate binaries without requiring source-level semantics: - NEGMAP (Naive Phase): Casts a wide baseline exploration net to monitor for semantic markers and basic block trajectories without getting bogged down in state explosion. - DEGMAP (Directed Phase): Dynamically steers state exploration toward high-value areas of memory interaction. - GMAP Discovery: Prioritizes the identification of Globally Accessed Memory Points (GMAPs)—locations where multiple threads contend for shared memory—applying a hybrid lock-set and happens-before analysis directly at the binary level. In empirical evaluations, XEGMAP achieved massive code coverage (scaling up to 36,755 blocks) and successfully identified up to 360 distinct GMAPs in complex environments without symbol tables.

Professor Sebastian Mallaby’s new book offers a definitive portrait of pre-2022 #ArtificialIntelligence, capturing a fleeting era when the field had true protagonists. Reviewer N Chandrasekhar Ramanujan observes how Demis Hassabis built Google DeepMind to solve grand scientific problems - such as protein folding - before the post - #ChatGPT gold rush forced a pivot towards #commercial rivalry. It stands as a compelling record of an industry rapidly shifting from noble ambition to faceless corporate infrastructure.

What does mathematics look like when the problem truly matters? As mathematicians from around the world gather in Philadelphia for the International Congress of Mathematicians, we are proud to share a new video exploring the mathematics behind Metron Inc.’s work. The ICM invited Metron to help show mathematicians how advanced mathematical methods are being applied to consequential, real-world problems. The video offers a look at how our teams use mathematics to search for what has been lost, make sense of uncertainty, and support critical decisions in complex and rapidly changing environments. For mathematicians who want to work on difficult problems with meaningful outcomes, this is what a career at Metron can look like.

If you’re wondering what it is I do… my answer is still 🤐. However, this promo video for Metron at ICM might give you a sense. We work on difficult problems in a technically rigorous way to deliver solutions that are backed up not just by our own credibility, but also by the underlying mathematics.

Honored and proud to have Metron Inc. featured at this year's International Congress of Mathematicians. For 42 years, we have successfully delivered innovative solutions to some of the most challenging problems in defense and nation security using a unique approach grounded in mathematical rigor, technical excellence, mission focus, and deep domain expertise. The video discusses a few of the problems we work on but more importantly, it highlights the "how" and "why" behind Metron Inc.'s work So proud of everyone on Team Metron Inc.
