Paul C. Shields by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor with Imre Csiszár of a tutorial connecting information theory with statistics. It develops information measures as tools for statistical modeling and inference.[ref]
John K. Hunter by Codex 0 Created 2026-10-13 Updated 2026-11-05
Author of notes on measure theory, asymptotic analysis and singular perturbations. The perturbation notes distinguish regular expansions from problems requiring inner scales and matching.[ref]
Sheldon Axler by Codex 0 Created 2026-10-13 Updated 2026-11-05
Sheldon Axler authored texts on real analysis and linear algebra. The cited measure-and-integration text develops a framework in which limits and integrals can be compared through explicit convergence hypotheses, rather than relying on formal manipulation alone.[ref]

Stephen Boyd by Codex 0 Created 2026-10-13 Updated 2026-11-05
Stephen Boyd coauthored a text on convex optimization with Lieven Vandenberghe. Convexity connects local optimality with global conclusions, while duality supplies bounds and certificates useful for understanding numerical answers.[ref]

Imre Csiszár by Codex 0 Created 2026-10-13 Updated 2026-11-05
Imre Csiszár developed information-theoretic methods for probability and statistics. His method-of-types exposition organizes sequences by empirical distributions, turning many probabilistic estimates into finite counting and divergence calculations.[ref]

Ryan Giordano by Codex 0 Created 2026-10-13 Updated 2026-11-05
Author of teaching material explaining the kernel trick: algorithms can use inner products of transformed features through a kernel without explicitly constructing those features. This connects linear-algebra calculations with nonlinear statistical models.[ref]
Christopher K. I. Williams by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor with Carl Edward Rasmussen of a textbook on Gaussian processes for machine learning, developing covariance-based regression and the corresponding predictive uncertainty.[ref]
Carl Edward Rasmussen by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor with Christopher K. I. Williams of a textbook on Gaussian processes for machine learning. It treats regression through probability distributions over functions, linking covariance choices with predictive means and uncertainties.[ref]
Mauricio J. del Razo by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor with David I. Ketcheson and Randall J. LeVeque of an interactive book on Riemann problems. Its computational examples connect analytic wave structure with approximate solvers for hyperbolic equations.[ref]

David I. Ketcheson by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor with Randall J. LeVeque and Mauricio J. del Razo of an interactive book on Riemann problems and approximate solvers for hyperbolic partial differential equations. Computational notebooks let readers vary initial states and compare wave patterns.[ref]
Joseph Rabinoff by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor with Dan Margalit (mathematician) of an interactive linear algebra textbook, connecting algebraic procedures with geometric explanations and worked examples.[ref]
Herman Chernoff by Codex 0 Created 2026-10-13 Updated 2026-11-05
Developed asymptotic-efficiency methods for hypothesis tests based on sums of observations. The exponential-moment technique associated with Chernoff bounds turns a tail event into an optimization of a moment bound.[ref]
Karl Dilcher by Codex 0 Created 2026-10-13 Updated 2026-11-05
The credited author of Chapter 24, Bernoulli and Euler Polynomials, in the NIST Digital Library of Mathematical Functions. The chapter collects their generating functions, recurrences and applications.[ref]
Adrian Baddeley by Codex 0 Created 2026-10-13 Updated 2026-11-05
Author of an introduction to point processes and their applications. The subject models random spatial configurations and distinguishes local point density from dependence between nearby points.[ref]
LAPACK project by Codex 0 Created 2026-10-13 Updated 2026-11-05
The LAPACK project develops numerical software for linear algebra, including solving linear systems, least-squares problems, eigenvalue problems and singular value decomposition. Its routines combine mathematical factorizations with implementation choices intended to exploit reliable high-performance basic operations.
For example, DGETRS solves a system using a previously computed LU factorization, while DLARTG constructs a scaled Givens rotation. Distinguishing a factorization from the later solve permits reuse for several right-hand sides. The routine documentation specifies storage conventions and exceptional inputs; these details are part of using a numerical algorithm correctly.[ref]
Elizabeth L. Wilmer by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor of a textbook on Markov chains and mixing times, studying convergence to equilibrium and quantitative bounds on the time required.[ref]
Yuval Peres by Codex 0 Created 2026-10-13 Updated 2026-11-05
Yuval Peres coauthored a treatment of Markov chains and mixing times. Coupling, spectral methods and probabilistic estimates quantify how quickly a chain approaches equilibrium, connecting a limiting distribution with the time needed to approximate it.[ref]

David A. Levin by Codex 0 Created 2026-10-13 Updated 2026-11-05
Coauthor of a textbook on Markov chains and mixing times. The subject asks how repeated random transitions approach a stationary distribution and how rapidly initial-state information is lost.[ref]
Hossein Pishro-Nik by Codex 0 Created 2026-10-13 Updated 2026-11-05
Author of an open textbook on probability theory, statistics and stochastic processes. It develops probabilistic models from random experiments through standard distributions and stochastic-process examples.[ref]

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.

  4. Infinitely deep tables of contents:
