Radioisotope Identification with List-Mode Gamma-Ray Data

Data Science in Science
This work explores the potential of utilizing temporal data from gamma-ray detectors, known as list-mode data, to enhance radioisotope identification. Traditional identification methods, which rely on full gamma-ray spectrum analysis, often require long ...

A copula model for marked point processes [PDF]

Lifetime Data Analysis, 2013
Many chronic diseases feature recurring clinically important events. In addition, however, there often exists a random variable which is realized upon the occurrence of each event reflecting the severity of the event, a cost associated with it, or possibly a short term response indicating the effect of a therapeutic intervention.

FURTHER RESULTS ON VARIANCES OF LOCAL STEREOLOGICAL ESTIMATORS

Image Analysis and Stereology, 2011
In the present paper the statistical properties of local stereological estimators of particle volume are studied. It is shown that the variance of the estimators can be decomposed into the variance due to the local stereological estimation procedure and ...

COMBINE MARKOV RANDOM FIELDS AND MARKED POINT PROCESSES TO EXTRACT BUILDING FROM REMOTELY SENSED IMAGES [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Automatic building extraction from remotely sensed images is a research topic much more significant than ever. One of the key issues is object and image representation.

A BSDE-based approach for the optimal reinsurance problem under partial information

, 2020
We investigate the optimal reinsurance problem under the criterion of maximizing the expected utility of terminal wealth when the insurance company has restricted information on the loss process.

Marked self-exciting point process modelling of information diffusion on Twitter [PDF]

Annals of Applied Statistics, 2018
Information diffusion occurs on microblogging platforms like Twitter as retweet cascades. When a tweet is posted, it may be retweeted and henceforth further retweeted, and the retweeting process continues iteratively and indefinitely.

Marked point process filter for clusterless and adaptive encoding-decoding of multiunit activity

bioRxiv, 2018
Real-time, closed-loop experiments can uncover causal relationships between specific neural activity and behavior. An important advance in realizing this is the marked point process filtering framework which utilizes the “mark” or the waveform features ...

Derivatives pricing with marked point processes using Tick-by-tick data [PDF]

, 2010
I propose to model stock price tick-by-tick data via a non-explosive marked point process. The arrival of trades is driven by a counting process in which the waiting-time between trades possesses a Mittag-Leffler survival function and price revisions ...

A Marked Point Process Approach for Continuous Valence Estimation Using Respiration Activity

IEEE Access
In this study, we present a method for continuously estimating emotional valence levels using a marked point process representation of features extracted from respiration amplitude signals.
