Data Science x Public HealthHow NLP Detects Public Health Trends from Text DataNatural 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/@BJANALYTICS Instagram: https://www.instagram.com/bjanalyticsconsulting/ Twitter/X: https://x.com/BJANALYTICS ...

The Marketing ArchitectsHow Brands REALLY Grow with Dale HarrisonMarketing can't force people to buy what they don't need. According to Dale Harrison, 65-90% of market share within a category is determined by brand recall at purchase.This week, Elena and Rob are joined by Dale Harrison, former experimental physicist turned marketing effectiveness expert. Dale breaks down the NBD-Dirichlet model that governs consumer behavior, explains why most growth stories have nothing to do with brilliant marketing, and reveals why reach (not targeting) drives market share. Plus, learn about the mathematical reality behind brand loyalty and why your job as a marketer is to make subtle nudges, not...

Best AI papers explainedPosterior Mean Matching Generative ModelingThis 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...

Loyalty UnlockedFollow the Crowd: The Science of Predicting Loyalty EnrolmentWhat if you could predict how millions of customers would behave before your loyalty programme even launched?
In this episode of Loyalty Unlocked, we explore why enrolment isn’t random — it’s remarkably consistent. From Galton’s bead box to Rogers’ Diffusion of Innovation and the predictive power of NBD-Dirichlet, we break down the behavioural science behind loyalty adoption.
You’ll hear how the 4–40–400 Rule has shaped some of the world’s biggest launches, including yuu Rewards, and how you can use it to estimate not just when customers will join — but how many. Because when you understand the crowd, you don’t need to gu

The Hebrew word תַּבְנִית (tabnît) carries a weight beyond “pattern” or “model.” It is the heavenly archetype, the blueprint revealed from above, which earthly builders are commanded to replicate with precision. Moses is told: “You are to set up the tabernacle according to the pattern (tabnît) that you were shown on the mountain” (Exod 26:30, NET)¹. The writer of Hebrews confirms this principle, reminding that priests “serve a copy and shadow of the heavenly things, just as Moses was warned when he was about to construct the tabernacle.

Fakultät für Physik - Digitale Hochschulschriften der LMU - Teil 04/05Gauge/Gravity dualityIn 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...

Mathematik, Informatik und Statistik - Open Access LMU - Teil 02/03Clustering in linear mixed models with approximate Dirichlet process mixtures using EM algorithmIn 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...
2013-02-0100 minMathematik, Informatik und Statistik - Open Access LMU - Teil 02/03A Technical Note on the Dirichlet-Multinomial ModelThis 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...

the way knowledge is shared all over the world. To make this unbelievable huge information
space accessible, search engines index the uploaded contents and provide efficient
algorithmic machinery for ranking the importance of documents with respect to an input
query. All major search engines such as Google, Yahoo or Bing are keyword-based, which
is indisputable a very powerful tool for accessing information needs centered around documents.
However, this unstructured, document-oriented paradigm of the World Wide Web has serious drawbacks, when searching for specific knowledge about real-world entities.

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...

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...

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.

scientists. In recent years one such a topic, information
filtering, emerges to help users find desired information items (e.g.~movies, books, news) from large amount of available data, and has become crucial in many applications, like product recommendation, image retrieval, spam email filtering, news filtering, and web navigation etc..
An information filtering system must be able to understand users' information needs. Existing approaches either infer a
user's profile by exploring his/her connections to other users, i.e.~collaborative filtering (CF), or...
