In this paper we propose two constructions of dependent normalized random measures, a class of nonparametric priors over dependent probability measures. Our constructions, which we call mixed normalized random measures (MNRM) and thinned normalized random measures (TNRM), involve (respectively) weighting and thinning parts of a shared underlying Poisson process before combining them together. W...
One of the problems faced by farmers in Indonesia is capital. Based on Indonesian Central Statistics Agency survey results, number who borrow capital from formal institutions such as banks still small. This because process applying for loans at lengthy, are considered high-risk and unbankable, rating agricultural sector unattractive to banks. study aims determine attributes design a model credi...
Random forest models have recently gained popularity for economic forecasting. Earlier studies demonstrated their potential to provide early warnings of recession and serve as a competitive method older prediction models. This study offers the first evaluation random forecast Czech economy. The one-step-ahead forecasting results show high accuracy on data are proven outperform forecasts from Mi...
The complex numerical climate models pose a big challenge for scientists in weather predictions, especially tropical system. This paper is focused on presenting the importance of prediction using machine learning (ML) technique. Recently many researchers recommended that can produce sensible predictions spite having no precise knowledge atmospheric physics. In this work, global solar radiation ...
Taking the invention patents of C9 League from 2002 to 2020 as samples, a random survival forest model is established predict dynamic time-point patent transfer cycle. By ranking variables based on importance, it found that countries citing, non-patent citations and backward have significant impacts C-index, Brier score integrated are used measure discrimination calibration ability four differe...

BACKGROUND/AIM We report on survival data of 595 patients with stage I-III lung cancer with respect to TNM classification. MATERIALS AND METHODS We constructed a basic model consisting of stage and grade, and assessed the improvement of survival prediction after adding comorbidity data, spirometric data, clinical and laboratory parameters. RESULTS Body mass index (BMI) and presence of a car...
Survival analysis represents an important outcome measure in clinical research and clinical trials; further, survival ranking may offer additional advantages in clinical trials. In this study, we developed GuanRank, a non-parametric ranking-based technique to transform patients' survival data into a linear space of hazard ranks. The transformation enables the utilization of machine learning bas...
