Intrinsic Investigations: Exploring the Impact of Original Student Research
Patterns in Buy Now, Pay Later Consumer Complaints
This episode's title refers to the themes Geffen uncovered in over 3,000 complaints filed with the Consumer Financial Protection Bureau. Using a machine learning method called Latent Dirichlet Allocation, he analyzes what consumers are actually saying about Buy Now, Pay Later companies and finds that the complaints go beyond hidden fees and confusing payment structures to something newer: the ways technology itself may be used to obscure what consumers are really agreeing to. His closing advice is worth the listen alone.Scrub to 1:10 to skip the introduction

Simetría en el Umbral: Himno Hiperbólico a los Grupos NEC
Una exploración sonora y matemática que habita en el límite donde el plano se dobla. Inspirada profundamente en el estilo tintinnabuli de Arvo Pärt, esta obra utiliza voces de soprano etéreas, drones de violonchelo y una reverberación catedralicia para narrar las leyes del espacio hiperbólico. A través de su letra, la canción nos guía por el disco de Poincaré, los dominios de Dirichlet y las firmas de los grupos NEC (Grupos Cristalográficos No Euclidianos). Es una música dedicada a la curvatura negativa constante, donde las reflexiones y simetrías crean un mo...

Today's clip is from Episode 154 of the podcast, with Thomas Pinder.In this conversation, Thomas Pinder explains how Bayesian methods naturally lend themselves to causal modeling, and why that matters for real-world business decisions. The key insight is that causal questions in industry are rarely black and white: instead of a single treatment effect, you get a full posterior distribution, credible intervals, and the ability to communicate the probability that an effect is positive, which is far more useful to stakeholders than a p-value.Thomas then dives into Bayesian Synthetic Control, a reframing...

How NLP Detects Public Health Trends from Text Data
Natural Language Processing (NLP) is transforming how public health trends are detected from text data. In this episode, we explain how NLP analyzes health reports, clinical notes, and public health documents to uncover patterns that traditional methods often miss. You’ll learn how word frequency analysis, topic modeling, and Latent Dirichlet Allocation (LDA) help identify emerging health trends, support early outbreak detection, and inform population-level public health decisions.Youtube: https://www.youtube.com/@BJANALYTICSInstagram: https://www.instagram.com/bjanalyticsconsulting/Twitter/X: https://x.com/BJANALYTICS...

Marketing can't force people to buy what they don't need.

Posterior Mean Matching Generative Modeling
This paper introduces Posterior Mean Matching (PMM), a novel generative modeling technique rooted in Bayesian inference. Unlike traditional diffusion models, PMM employs conjugate pairs of distributions to flexibly model diverse data types such as images and text. The core mechanism involves iteratively refining noisy data approximations through online Bayesian inference updates, with the convergence of the posterior mean to the true data sample forming the basis for generating new data. The authors demonstrate PMM's versatility by applying it to real-valued, count, and discrete data using Normal-Normal, Gamma-Poisson, and Dirichlet-Categorical models, respectively, establishing connections to stochastic differential equations...

Gauge/Gravity duality
In der vorliegenden Arbeit wird mit Hilfe der verallgemeinerten Eichtheorie/Gravitations-Dualität, welche stark gekoppelte Eichtheorien mit schwach gekrümmten gravitativen Theorien verbindet, stark korrelierte Quantenzustände der Materie untersucht. Der Schwerpunkt liegt dabei in Anwendungen auf Systeme der kondensierten Materie, insbesondere Hochtemperatur-Supraleitung und kritische Quantenzustände bei verschwindender Temperatur. Die Eichtheorie/Gravitations-Dualität entstammt der Stringtheorie und erlaubt eine Umsetzung des holographischen Prinzips. Aus diesem Grund wird eine kurze Einführung in die Konzepte der Stringtheorie und ihre Auswirkungen auf das holographische Prinzip gegeben. Für das tiefere Verständnis der effektiven Niederenergie-Feldtheorien wird zusätzlich die Supersymmetrie benötigt. Ausg...

Clustering in linear mixed models with approximate Dirichlet process mixtures using EM algorithm
In linear mixed models, the assumption of normally distributed random effects is often inappropriate and unnecessarily restrictive. The proposed approximate Dirichlet process mixture assumes a hierarchical Gaussian mixture that is based on the truncated version of the stick breaking presentation of the Dirichlet process. In addition to the weakening of distributional assumptions, the specification allows to identify clusters of observations with a similar random effects structure. An Expectation-Maximization algorithm is given that solves the estimation problem and that, in certain respects, may exhibit advantages over Markov chain Monte Carlo approaches when modelling with Dirichlet processes. The method is evaluated in...

A Technical Note on the Dirichlet-Multinomial Model
This short note contains an explicit proof of the Dirichlet distribution being the conjugate prior to the Multinomial sample distribution as resulting from the general construction method described, e.g., in Bernardo and Smith (2000). The well-known Dirichlet-Multinomial model is thus shown to fit into the framework of canonical conjugate analysis (Bernardo and Smith 2000, Prop.~5.6, p.~273), where the update step for the prior parameters to their posterior counterparts has an especially simple structure. This structure is used, e.g., in the Imprecise Dirichlet Model (IDM) by Walley (1996), a simple yet powerful model for imprecise Bayesian inference using sets of Dirichlet priors...

Statistical relational learning with nonparametric Bayesian models
Statistical relational learning analyzes the probabilistic constraints between the entities, their attributes and relationships. It represents an area of growing interest in modern data mining. Many leading researches are proposed with promising results. However, there is no easily applicable recipe of how to turn a relational domain (e.g. a database) into a probabilistic model. There are mainly two reasons. First, structural learning in relational models is even more complex than structural learning in (non-relational) Bayesian networks due to the exponentially many attributes an attribute might depend on. Second, it might be difficult and expensive to obtain reliable prior knowledge...

Advanced Probabilistic Models for Clustering and Projection
Probabilistic modeling for data mining and machine learning problems is a fundamental research area. The general approach is to assume a generative model underlying the observed data, and estimate model parameters via likelihood maximization. It has the deep probability theory as the mathematical background, and enjoys a large amount of methods from statistical learning, sampling theory and Bayesian statistics. In this thesis we study several advanced probabilistic models for data clustering and feature projection, which are the two important unsupervised learning problems. The goal of clustering is to group similar data points together to uncover the data clusters. While numerous...

A nonparametric predictive alternative to the Imprecise Dirichlet Model: the case of a known number of categories
Nonparametric Predictive Inference (NPI) is a general methodology to learn from data in the absence of prior knowledge and without adding unjustified assumptions. This paper develops NPI for multinomial data where the total number of possible categories for the data is known. We present the general upper and lower probabilities and several of their properties. We also comment on differences between this NPI approach and corresponding inferences based on Walley's Imprecise Dirichlet Model.
