Due to the surplus of astrometric\u0000data, the current computational methods employed to inspect these astrometric\u0000binary candidates are both computationally expensive and cannot be executed in\u0000a reasonable time frame. In light of this, a machine learning (ML) technique to\u0000automatically classify whether a set of stars belong to an astrometric binary\u0000pair via an artificial neural network (ANN) is proposed. Using data from Gaia\u0000DR3, the ANN was trained and tested on 1.5 million highly probable true and\u0000visual binaries, considering the proper motions, parallaxes, and angular and\u0000physical separations as features. The ANN achieves high classification scores,\u0000with an accuracy of 99.3%, a precision rate of 0.988, a recall rate of 0.991,\u0000and an AUC of 0.999, indicating that the utilized ML technique is a highly\u0000effective method for classifying astrometric binaries. Thus, the proposed ANN\u0000is a promising alternative to the existing methods for the classification of\u0000astrometric binaries.","PeriodicalId":501065,"journal":{"name":"arXiv - PHYS - Data Analysis, Statistics and Probability","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One common issue is generating\u0000training data which is sufficiently realistic to give reliable results. Here we\u0000advocate using real experimental data as the source of training data and\u0000demonstrate how one might subtract background contributions through the use of\u0000probabilistic weights which can be readily applied to training data. The sPlot\u0000formalism is a common tool used to isolate distributions from different\u0000sources. However, negative sWeights produced by the sPlot technique can lead to\u0000issues in training and poor predictive power. This article demonstrates how\u0000density ratio estimation can be applied to convert sWeights to event\u0000probabilities, which we call drWeights. The drWeights can then be applied to\u0000produce the distributions of interest and are consistent with direct use of the\u0000sWeights. This article will also show how decision trees are particular well\u0000suited to converting sWeights, with the benefit of fast prediction rates and\u0000adaptability to aspects of the experimental data such as data sample size and\u0000proportions of different event sources. We also show that a double density\u0000ratio approach where the initial drWeights are reweighted by an additional\u0000classifier gives substantially better results.","PeriodicalId":501065,"journal":{"name":"arXiv - PHYS - Data Analysis, Statistics and Probability","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142179395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phase reduction theory serves as a useful analytical framework\u0000for elucidating the synchronization mechanism of these oscillators.\u0000Essentially, this theory describes the dynamics of a multi-dimensional\u0000nonlinear oscillator using a single variable phase model. In order to\u0000understand and control the rhythmic phenomena in the real world, it is crucial\u0000to estimate the asymptotic phase from the observed data. In this study, we\u0000propose a new method, Gaussian Process Phase Interpolation (GPPI), for\u0000estimating the asymptotic phase from time series data. The GPPI method first\u0000evaluates the asymptotic phase on the limit cycle and subsequently estimates\u0000the asymptotic phase outside the limit cycle employing Gaussian process\u0000regression.
