A Tutorial on the Expectation-Maximization Algorithm Including Maximum-Likelihood Estimation and EM Training of Probabilistic Context-Free Grammars

, 2004
The paper gives a brief review of the expectation-maximization algorithm (Dempster 1977) in the comprehensible framework of discrete mathematics. In Section 2, two prominent estimation methods, the relative-frequency estimation and the maximum-likelihood

How do US Adults Who Vape Choose Among Different E‐Cigarette (EC) Models and Cigarettes in Response to Prices and Taxes

Health Economics, EarlyView.
ABSTRACT States continue to impose E‐Cigarette (EC) taxes without clear evidence of the cross‐price elasticities between multiple EC types and between ECs and cigarettes. Moreover, existing literature focused on EC sales or prevalence outcomes instead of consumption units of various EC types.

The Potential of Unsupervised Induction of Harmonic Syntax for Jazz

Transactions of the International Society for Music Information Retrieval
Hierarchical structures describing a syntax of harmony have long been studied and proposed by music theorists, but algorithms that model these structures either require costly expert annotations for training or are based on music theorists ...

Probabilistic grammar and constructional predictability: Bayesian generalized additive models of help + (to) Infinitive in varieties of web-based English

Glossa, 2018
The present study investigates the construction with help followed by the bare or to-infinitive in seven varieties of web-based English from Australia, Ghana, Great Britain, Hong Kong, India, Jamaica and the USA. In addition to various factors known from

PelviSound L—Real‐time intraoperative sonographic assessment of pelvic sentinel lymph nodes using a drop‐in probe in endometrial and cervical cancer during minimally invasive surgery: A single‐center pilot feasibility study in 20 patients

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Sentinel lymph node biopsy (SLNB) is considered an essential step in the surgical management of endometrial and cervical cancers as it has led to a reduction in the need for full pelvic lymphadenectomy. This proof‐of‐concept study aimed to evaluate the feasibility and diagnostic performance of intraoperative sonographic assessment of

Second‐trimester multimetabolite panel for early preeclampsia rule‐out

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We aimed to establish a high‐sensitivity, multimetabolite rule‐out model for the development of preeclampsia (PE), prioritizing minimizing false negatives to exclude low‐risk individuals from intensive surveillance confidently. Methods In this prospective, nested case–control study, maternal serum samples were collected between 20+0 ...

Genomic epidemiology and lineage‐specific risk stratification of tet(X4)‐mediated tigecycline resistance along the pork production chain: A One Health perspective

iMetaOmics, EarlyView.
Genome surveillance across a swine‐associated One Health continuum in China shows that slaughterhouses act as major enrichment nodes for tet(X4)‐mediated tigecycline resistance, driven by putative clonal transmission and stable plasmid backbones. Integrating global datasets enables lineage‐specific risk stratification, highlighting key control points ...

The Role of Admission Probabilities in the Deferred Acceptance Mechanism: An Experimental Study

International Studies of Economics, EarlyView.
ABSTRACT Although students theoretically need not consider admission probabilities under strategy‐proof mechanisms in school choice problems, our study reveals a significant correlation between students' applications and their beliefs about admission probabilities in the deferred acceptance mechanism.
