A flexible machine learning framework, Venn machine VM was introduced to make probabilistic predictions for each prediction. Three Venn predictors and three classical probabilistic prediction methods were compared in aspect of classification rate and especially the validity of estimated probability.
A best classification rate of The validity of Venn predictors performed better than that of corresponding classical probabilistic prediction methods. The results demonstrated that Venn machine is a flexible tool to make precise and valid probabilistic prediction in the application of E-nose, and VM-SVM achieved the best performance for the probabilistic prediction of ginseng samples. This paper proposes a new approach to improving our understanding of the suitability of internet discussion forums for use by health information seekers.
We consider in particular their potential use during public health emergencies when access to conventional experts and healthcare professionals may be constrained.
We explore potential benefits and challenges of crowdsourcing information on health issues in online environments through the context of Computer Science theories of Collective Intelligence [1, 2], which explore how members of a group - particularly when networked by computer systems - can reach a better solution than an individual working alone. We study optimal conformity measures for various criteria of efficiency in an idealised setting.
This leads to an important class of criteria of efficiency that we call probabilistic; it turns out that the most standard criteria of efficiency used in literature on conformal prediction are not probabilistic. We construct a universal prediction system in the spirit of Popper's falsifiability and Kolmogorov complexity. This prediction system does not depend on any statistical assumptions, but under the IID assumption it dominates, although in a rather weak sense, conformal prediction. Despite the extensive attention on traditional stability of data perturbations or parameter variations, few studies include influences coming from the intrinsic randomness in generating VIMs, i.
To address these influences, in this paper we introduce a new concept of intrinsic stability of VIMs, which is defined as the self-consistence among feature rankings in repeated runs of VIMs without data perturbations and parameter variations. Two widely used VIMs, i. The motivation of this study is two-fold. First, we empirically verify the prevalence of intrinsic stability of VIMs over many real-world datasets to highlight that the instability of VIMs does not originate exclusively from data perturbations or parameter variations, but also stems from the intrinsic randomness of VIMs.
Second, through Spearman and Pearson tests we comprehensively investigate how different factors influence the intrinsic stability. This paper reports a hybrid system consisting of a homemade electronic nose system E-nose with a sensor array of 16 metal-oxide sensors and a near-infrared reflectance spectroscopy NIRS system for discriminating different kinds of ginsengs. Six commonly used features were extracted from each sensor in the E-nose sensor array. Then, models were built and trained with a support vector machine separately using datasets of the two systems.
The classification performances of individual systems were optimized and compared. The advantages and disadvantages of the two systems were demonstrated by comparing empirical probability distributions in the category of predict labels for all samples. Finally, new weighted feature-level data-fusion and Dempster—Shafer-theory based decision-level data-fusion approaches for the hybrid system were separately exploited. The results showed that the hybrid system achieved an optimal classification accuracy of Sort by year:.
Summary Algorithmic Learning in a Random World describes recent theoretical and experimental developments in building computable approximations to Kolmogorov's algorithmic notion of randomness. Summary Data analysis and inference have traditionally been research areas of statistics. Summary This book is devoted to two interrelated techniques in solving some important problems in machine intelligence and pattern recognition, namely probabilistic reasoning and computational learning. Summary The conformal predictions framework is a recent development in machine learning that can associate a reliable measure of confidence with a prediction in any real-world pattern recognition application, including risk-sensitive applications such as medical diagnosis, face recognition, and financial risk prediction.
Summary This book celebrates the work of Vladimir Vapnik, developer of the support vector machine, which combines methods from statistical learning and functional analysis to create a new approach to learning problems, and who continues as active as ever in his field. Summary This book brings together historical notes, reviews of research developments, fresh ideas on how to make VC Vapnik—Chervonenkis guarantees tighter, and new technical contributions in the areas of machine learning, statistical inference, classification, algorithmic statistics, and pattern recognition.

Abstract Conformal predictive systems are a recent modification of conformal predictors that output, in regression problems, probability distributions for labels of test observations rather than set predictions. Abstract This note explains how conformal predictive distributions can be used for the purpose of decision-making. Abstract Venn predictors are a distribution-free probabilistic prediction framework that transforms the output of a scoring classifier into a multi- probabilistic prediction that has calibration guarantees, with the only requirement of an i.

Inferring causation from time series with perspectives in Earth system sciences Nature Communications , article In revision [BibTex]. Lim, J. Hohmann, M. Bruijns, S. Abstract Variational Autoencoders VAEs provide a theoretically-backed framework for deep generative models. Sampling in the most popular implementation, the Gaussian VAE, can be interpreted as simply injecting noise to the input of a deterministic decoder.
In practice, this simply enforces a smooth latent space structure. We challenge the adoption of the full VAE framework on this specific point in favor of a simpler, deterministic one. Specifically, we investigate how substituting stochasticity with other explicit and implicit regularization schemes can lead to a meaningful latent space without having to force it to conform to an arbitrarily chosen prior.
To retrieve a generative mechanism for sampling new data points, we propose to employ an efficient ex-post density estimation step that can be readily adopted both for the proposed deterministic autoencoders as well as to improve sample quality of existing VAEs.
