    Expectation-Maximization Algorithm of Gaussian Mixture Model for Vehicle-Commodity Matching in Logistics Supply Chain.Qi Sun, Liwen Jiang & Haitao Xu - 2021 - Complexity 2021:1-11.
    A vehicle-commodity matching problem is presented for service providers to reduce the cost of the logistics system. The vehicle classification model is built as a Gaussian mixture model, and the expectation-maximization algorithm is designed to solve the parameter estimation of GMM. A nonlinear mixed-integer programming model is constructed to minimize the total cost of VCMP. The matching process between vehicle and commodity is realized by GMM-EM, as a preprocessing of the solution. The design of the vehicle-commodity matching platform for (...)

    Simulation of Tennis Match Scene Classification Algorithm Based on Adaptive Gaussian Mixture Model Parameter Estimation.Yuwei Wang & Mofei Wen - 2021 - Complexity 2021:1-12.
    This paper presents an in-depth analysis of tennis match scene classification using an adaptive Gaussian mixture model parameter estimation simulation algorithm. We divided the main components of semantic analysis into type of motion, distance of motion, speed of motion, and landing area of the tennis ball. Firstly, for the problem that both people and tennis balls in the video frames of tennis matches from the surveillance viewpoint are very small, we propose an adaptive Gaussian mixture model parameter estimation (...)

    Damage Detection of Refractory Based on Principle Component Analysis and Gaussian Mixture Model.Changming Liu, Zhigang di ZhouWang, Dan Yang & Gangbing Song - 2018 - Complexity 2018:1-9.
    Acoustic emission technique is a common approach to identify the damage of the refractories; however, there is a complex problem since there are as many as fifteen involved parameters, which calls for effective data processing and classification algorithms to reduce the level of complexity. In this paper, experiments involving three-point bending tests of refractories were conducted and AE signals were collected. A new data processing method of merging the similar parameters in the description of the damage and reducing the dimension (...)

    Robot Motion Planning Method Based on Incremental High-Dimensional Mixture Probabilistic Model.Fusheng Zha, Yizhou Liu, Xin Wang, Fei Chen, Jingxuan Li & Wei Guo - 2018 - Complexity 2018:1-14.
    The sampling-based motion planner is the mainstream method to solve the motion planning problem in high-dimensional space. In the process of exploring robot configuration space, this type of algorithm needs to perform collision query on a large number of samples, which greatly limits their planning efficiency. Therefore, this paper uses machine learning methods to establish a probabilistic model of the obstacle region in configuration space by learning a large number of labeled samples. Based on this, the high-dimensional samples’ rapid collision (...)

    カーネル密度推定器としての実数値交叉: Undx に基づく交叉カーネルの提案.Kobayashi Shigenobu Sakuma Jun - 2007 - Transactions of the Japanese Society for Artificial Intelligence 22 (5):520-530.
    This paper presents a kernel density estimation method by means of real-coded crossovers. Functions of real-coded crossover operators are composed of probabilistic density estimation from parental populations and sampling from estimated models. Real-coded Genetic Algorithm (RCGA) does not explicitly estimate probabilistic distributions, however, probabilistic model estimation is implicitly included in algorithms of real-coded crossovers. Based on this understanding, we exploit the implicit estimation of probabilistic distribution of crossovers as a kernel density estimator. We also propose an application of crossover kernels (...)

    確率的 Web 画像収集.Yanai Keiji - 2007 - Transactions of the Japanese Society for Artificial Intelligence 22 (1):10-18.
    We propose a novel probabilistic image selection method for the Web image gathering system we proposed before. It employed two-step processing: (1) Gather HTML files of Web pages related to given keywords, analyze them and fetch only Web images expected to be highly related to the keywords. (2) Select only relevant images from the gathered images based on the image-feature-based clustering. In this paper, we propose building a generative model based on the Gaussian mixture model to represent the distribution (...)

    Automatic moving object detection and tracking is very important task in video surveillance applications. In the present work the well known background subtraction model and use of Gaussian Mixture Models have been used to implement a robust automated single object tracking system. In this implementation, background subtraction on subtracting consecutive frame-by-frame basis for moving object detection is done. Once the object has been detected it is tracked by employing an efficient GMM technique. After successful completion of tracking, moving object (...)

    Unifying Gaussian LWF and AMP Chain Graphs to Model Interference.Jose M. Peña - 2020 - Journal of Causal Inference 8 (1):1-21.
    An intervention may have an effect on units other than those to which it was administered. This phenomenon is called interference and it usually goes unmodeled. In this paper, we propose to combine Lauritzen-Wermuth-Frydenberg and Andersson-Madigan-Perlman chain graphs to create a new class of causal models that can represent both interference and non-interference relationships for Gaussian distributions. Specifically, we define the new class of models, introduce global and local and pairwise Markov properties for them, and prove their equivalence. We also (...)

    Robust Gaussian Noise Detection and Removal in Color Images using Modified Fuzzy Set Filter.E. Srinivasa Reddy & Akula Suneetha - 2020 - Journal of Intelligent Systems 30 (1):240-257.
    In the data collection phase, the digital images are captured using sensors that often contaminated by noise (undesired random signal). In digital image processing task, enhancing the image quality and reducing the noise is a central process. Image denoising effectively preserves the image edges to a higher extend in the flat regions. Several adaptive filters (median filter, Gaussian filter, fuzzy filter, etc.) have been utilized to improve the smoothness of digital image, but these filters failed to preserve the image edges (...)

    Adaptive Gaussian Incremental Expectation Stadium Parameter Estimation Algorithm for Sports Video Analysis.Lizhi Geng - 2021 - Complexity 2021:1-10.
    In this paper, we propose an adaptive Gaussian incremental expectation stadium parameter estimation algorithm for sports video analysis and prediction through the study and analysis of sports videos. The features with more discriminative power are selected from the set of positive and negative templates using a feature selection mechanism, and a sparse discriminative model is constructed by combining a confidence value metric strategy. The sparse generative model is constructed by combining L1 regularization and subspace representation, which retains sufficient representational power (...)

    Mixtures and Psychological Inference with Resting State fMRI.Joseph McCaffrey & David Danks - 2022 - British Journal for the Philosophy of Science 73 (3):583-611.
    In this essay, we examine the use of resting state fMRI data for psychological inferences. We argue that resting state studies hold the paired promises of discovering novel functional brain networks, and of avoiding some of the limitations of task-based fMRI. However, we argue that the very features of experimental design that enable resting state fMRI to support exploratory science also generate a novel confound. We argue that seemingly key features of resting state functional connectivity networks may be artefacts resulting (...)

    A Gaussian Process Latent Variable Model for Subspace Clustering.Shangfang Li - 2021 - Complexity 2021:1-7.
    Effective feature representation is the key to success of machine learning applications. Recently, many feature learning models have been proposed. Among these models, the Gaussian process latent variable model for nonlinear feature learning has received much attention because of its superior performance. However, most of the existing GPLVMs are mainly designed for classification and regression tasks, thus cannot be used in data clustering task. To address this issue and extend the application scope, this paper proposes a novel GPLVM for clustering. (...)

  14. Macroscopic Mixtures.Paul Needham - 2007 - Journal of Philosophy 104 (1):26-52.
    This paper takes up issues related to the notion of chemical substances arising from their mereological and modal features. Related notions are elements and compounds, into which substances are sub-divided, and the general notion of mixture, which as a special case might involve several substances, but covers other cases too. These are essentially macroscopic concepts. Some of the chemical arguments for this claim have been presented elsewhere. The present paper is a metaphysical treatment of matter as categorised by the (...)

    Gaussian-Based Soft Computing Approach to Alternative Banking System for Sustainable Financial Sector.Fan Yang, Hakan Kalkavan, Hasan Dinçer, Serhat Yüksel & Serkan Eti - 2021 - Complexity 2021:1-27.
    This study aims to identify the necessary strategies for the development of a sustainable financial system. For this purpose, a novel approach could be provided for soft computing with Gaussian-based fuzzy DEMATEL approach to understand the significant levels and impact-relation degrees of these criteria. For robustness check, this evaluation has also been performed for triangular and trapezoidal fuzzy sets. There are many novelties of this study. Firstly, computer science has a significant role in the decision-making process. Another specificity is that (...)

    Using a Gaussian Graphical Model to Explore Relationships Between Items and Variables in Environmental Psychology Research.Nitin Bhushan, Florian Mohnert, Daniel Sloot, Lise Jans, Casper Albers & Linda Steg - 2019 - Frontiers in Psychology 10:453193.
    Exploratory analyses are an important first step in psychological research, particularly in problem-based research where various variables are often included from multiple theoretical perspectives not studied together in combination before. Notably, exploratory analyses aim to give first insights into how items and variables included in a study relate to each other. Typically, exploratory analyses involve computing bivariate correlations between items and variables and presenting them in a table. While this is suitable for relatively small data sets, such tables can easily (...)

    Representing Mixtures.James Wills - forthcoming - Philosophy of Science:1-37.
    I describe two candidate representations of a mixture. The first, which I call the ‘standard representation’, is not a good representation of a mixture in spite of its widespread popularity. The second, which I call ‘Gibbs’ representation’, is less widely adopted but is, I argue, a much better representation. I show that, once we have a precise mathematical structure that can be used to represent thermodynamic systems, and once an adequate perspective on representation is adopted, Gibbs’ representation trumps (...)

    'Hermaphroditical mixtures': Margaret Cavendish on nature and art.Susan James - 2018 - In Emily Thomas, Early Modern Women on Metaphysics. New York, NY: Cambridge University Press.
    Cavendish is critical of two of the experimental sciences of her day: chemistry and microscopy. Rather than creating new things, as their practitioners claim, they produce 'hermaphroditical mixtures'. I trace this startling metaphor to the alchemical tradition and suggest how its origins can help us to understand Cavendish's position. In her view, the chemists and microscopists exaggerate their own power and creativity, and fail to recognise that human creativity belongs primarily to imagination. I show how this theme is worked out (...)

    Mixture and Transformation in Aristotle’s De generatione et corruptione.Arman Zarifian - 2018 - Peitho 9 (1):53-69.
    In his works on natural sciences, primarily in the Physics, Aristotle focuses on different forms of metabolē and distinguishes movement in general from substantial change. The On generation and corruption deals with the latter. When reading this treatise, one should pay particular attention to the concept of mixture. Apart from being the subject of a specific chapter, the problem of mixture permeates the whole work. But what exactly is mixture? Is it a simple combination of small parts? (...)

    Expected utility theory on mixture spaces without the completeness axiom.David McCarthy, Kalle M. Mikkola & Teruji Thomas - 2021 - Journal of Mathematical Economics 97 (December 2021).
    A mixture preorder is a preorder on a mixture space (such as a convex set) that is compatible with the mixing operation. In decision theoretic terms, it satisfies the central expected utility axiom of strong independence. We consider when a mixture preorder has a multi-representation that consists of real-valued, mixture-preserving functions. If it does, it must satisfy the mixture continuity axiom of Herstein and Milnor (1953). Mixture continuity is sufficient for a mixture-preserving multi-representation (...)

    Learning linear non-Gaussian graphical models with multidirected edges.Huanqing Wang, Elina Robeva & Yiheng Liu - 2021 - Journal of Causal Inference 9 (1):250-263.
    In this article, we propose a new method to learn the underlying acyclic mixed graph of a linear non-Gaussian structural equation model with given observational data. We build on an algorithm proposed by Wang and Drton, and we show that one can augment the hidden variable structure of the recovered model by learning multidirected edges rather than only directed and bidirected ones. Multidirected edges appear when more than two of the observed variables have a hidden common cause. We detect the (...)

    A Multiobjective Particle Swarm Optimization Algorithm Based on Competition Mechanism and Gaussian Variation.Hongli Yu, Yuelin Gao & Jincheng Wang - 2020 - Complexity 2020:1-23.
    In order to solve the shortcomings of particle swarm optimization in solving multiobjective optimization problems, an improved multiobjective particle swarm optimization algorithm is proposed. In this study, the competitive strategy was introduced into the construction process of Pareto external archives to speed up the search process of nondominated solutions, thereby increasing the speed of the establishment of Pareto external archives. In addition, the descending order of crowding distance method is used to limit the size of external archives and dynamically adjust (...)

    Depth — A Gaussian Tradition in Mathematics.Jeremy Gray - 2015 - Philosophia Mathematica 23 (2):177-195.
    Mathematicians use the word ‘deep’ to convey a high appreciation of a concept, theorem, or proof. This paper investigates the extent to which the term can be said to have an objective character by examining its first use in mathematics. It was a consequence of Gauss's work on number theory and the agreement among his successors that specific parts of Gauss's work were deep, on grounds that indicate that depth was a structural feature of mathematics for them. In contrast, French (...)

    Aristotle’s On generation and corruption raises a vital question: how is mixture, or what we would now call chemical combination, possible? It also offers an outline of a solution to the problem and a set of criteria that a successful solution must meet. Understanding Aristotle’s solution and developing a viable peripatetic theory of chemical combination has been a source of controversy over the last two millennia. We describe seven criteria a peripatetic theory of mixture must satisfy: uniformity, recoverability, (...)

    Speaker Identification Using Empirical Mode Decomposition-Based Voice Activity Detection Algorithm under Realistic Conditions.R. Kumaraswamy, V. Kamakshi Prasad, Nilabh Kumar Pathak & M. S. Rudramurthy - 2014 - Journal of Intelligent Systems 23 (4):405-421.
    Speaker recognition under mismatched conditions is a challenging task. Speech signal is nonlinear and nonstationary, and therefore, difficult to analyze under realistic conditions. Also, in real conditions, the nature of the noise present in speech data is not known a priori. In such cases, the performance of speaker identification or speaker verification degrades considerably under realistic conditions. Any SR system uses a voice activity detector as the front-end subsystem of the whole system. The performance of most VADs deteriorates at the (...)

    Mixtures and modality.Paul Needham - 2004 - Foundations of Chemistry 7 (1):103-118.
    Some points are made about substance properties in their role of introducing mass terms. In particular, two conditions of distributivity and cumulativity of mass predicates expressing these properties are not the independent pair they first appear to be. A classification of macroscopic substance concepts is developed. This needs to be complemented in some way by the introduction of a modal qualification reminiscent of Aristotle's distinction between actual and potential presence of substances in a mixture. Consideration of the latter feature (...)

The performance of this proposed SV system was studied under degraded conditions with 50 selected speakers (...)

    Grains, Components and Mixtures in Biomedical Ontologies.Ludger Jansen & Schulz Stefan - 2011 - Journal of Biomedical Semantics 2 (4).

This paper investigates two important subrelations of has_proper_part, viz. the relation has_grain, which relates a collective entity to its multiply occurring uniform parts (e.g., water molecules in a portion of water), and the relation has_component, which relates a compound to its constituents (e.g., molecules to the atoms they consist of). -/- METHOD -/- (...)

    Gandhi: the Mixture Was the Essence. [REVIEW]Nishikant Kolge - 2020 - Journal of Dharma Studies 3 (1):207-214.
    Like Samiksha Goyal, many have asked—was Gandhi a Philosopher, deeply committed to moral principles, or a mass leader who was political strategist par excellence? In my response, I argue that scholars have created a false dichotomy between Gandhi the philosopher and Gandhi the pragmatic politician because usually these two are considered as different as chalk and cheese. Politicians are not expected to be moral and spiritual persons are not expected to be pragmatic. But, this article explains that it is wrong (...)

    From a modern point of view, compounds are contrasted with elements of which they are composed, and the two categories combine to give the category of substances. Mixtures, on the other hand, might be understood to contrast with pure substances (substances in isolation), so that mixtures are quantities of matter containing several substances (be they compounds or uncombined elements) whereas pure substances are understood to be quantities of matter exhausting the material contents of a region of space which contain only (...)

    Gene clustering is a useful exploratory technique to group together genes with similar expression levels under distinct cell cycle phases or distinct conditions. It helps the biologist to identify potentially meaningful relationships between genes. In this study, we propose a clustering method based on multivariate normal mixture models, where the number of clusters is predicted via sequential hypothesis tests: at each step, the method considers a mixture model of m components (m = 2 in the first step) and (...)

    For Anaxagoras, both before the beginning of the world and in the present, “all is together” and “everything is in everything.” Various modern interpretations abound regarding the identity of this “mixture.” It has been explained as an aggregation of particles or as a continuous “fusion” of different sorts of ingredients. However—even though they are not usually recognized as a distinct group—there are a number of other scholars who, without seemingly knowing each other, have offered a different interpreta- tion: Anaxagoras’ (...)

Xenophobia at its least reprehensible, he argues, is a fear of ecumenism and its consequences, as well as a fear of one's own conversion — of “turning Turk.” Xenophilia (...)

    The Q-Matrix Anchored Mixture Rasch Model.Ming-Chi Tseng & Wen-Chung Wang - 2021 - Frontiers in Psychology 12.
    Mixture item response theory models include a mixture of latent subpopulations such that there are qualitative differences between subgroups but within each subpopulation the measure model based on a continuous latent variable holds. Under this modeling framework, students can be characterized by both their location on a continuous latent variable and by their latent class membership according to Students’ responses. It is important to identify anchor items for constructing a common scale between latent classes beforehand under the (...) IRT framework. Then, all model parameters across latent classes can be estimated on the common scale. In the study, we proposed Q-matrix anchored mixture Rasch model, including a Q-matrix and the traditional mixture Rasch model. The Q-matrix in QAMRM can use class invariant items to place all model parameter estimates from different latent classes on a common scale regardless of the ability distribution. A simulation study was conducted, and it was found that the estimated parameters of the QAMRM recovered fairly well. A real dataset from the Certificate of Proficiency in English was analyzed with the QAMRM, LCDM. It was found the QAMRM outperformed the LCDM in terms of model fit indices. (shrink)

    Galen on the Stoic-Peripatetic Controversy about Mixtures: Qualities or Bodies?Claudia Mirrione - 2023 - Elenchos: Rivista di Studi Sul Pensiero Antico 44 (2):295-311.
    Galen’s elemental mixture of fire, air, water and earth (and of the corresponding primary qualities, hot, cold, dry and wet) is primarily a physical process, in which primary elements mix and give rise to all compounded physical bodies, inanimate and animate. As such, the concrete, physical process of mixture is an essential basis for a thorough understanding of Galen’s physical system. In this article I pursued a twofold aim. First, I showed Galen’s syncretic approach while expounding his theory (...)

    Multilingual Speaker Identification by Combining Evidence from LPR and Multitaper MFCC.H. S. Jayanna & B. G. Nagaraja - 2013 - Journal of Intelligent Systems 22 (3):241-251.
    In this work, the significance of combining the evidence from multitaper mel-frequency cepstral coefficients, linear prediction residual, and linear prediction residual phase features for multilingual speaker identification with the constraint of limited data condition is demonstrated. The LPR is derived from linear prediction analysis, and LPRP is obtained by dividing the LPR using its Hilbert envelope. The sine-weighted cepstrum estimators with six tapers are considered for multitaper MFCC feature extraction. The Gaussian mixture model–universal background model is used for modeling (...)

    College Students’ Psychological Health Analysis Based on Multitask Gaussian Graphical Models.Qiang Tian, Rui Wang, Shijie Li, Wenjun Wang, Ou Wu, Faming Li & Pengfei Jiao - 2021 - Complexity 2021:1-17.
    Understanding and solving the psychological health problems of college students have become a focus of social attention. Complex networks have become important tools to study the factors affecting psychological health, and the Gaussian graphical model is often used to estimate psychological networks. However, previous studies leave some gaps to overcome, including the following aspects. When studying networks of subpopulations, the estimation neglects the intrinsic relationships among subpopulations, leading to a large difference between the estimated network and the real network. Because (...)

    Lipophilic Environmental Chemical Mixtures Released During Weight‐Loss: The Need to Consider Dynamics.Duk-Hee Lee, David R. Jacobs, Lars Lind & P. Monica Lind - 2020 - Bioessays 42 (6):1900237.
    Intentional weight loss can increase health risk in the long‐term, despite short‐term benefits, because human adipose tissue is widely contaminated with various lipophilic environmental contaminants, especially persistent organic pollutants (POPs). Recently, chronic exposure to low POPs has emerged as a new risk factor for common metabolic diseases and cardiovascular diseases. The amount of POPs released from adipocytes to the circulation increases during weight loss, thereby increasing POPs exposure of other critical organs. Possible harmful effects due to release of POPs during (...)

    Robust Algorithms for a Multimodal Biometric System Using Palmprint and Speech.R. Raghavendra - 2011 - Journal of Intelligent Systems 20 (4):305-326.
    In this paper, we propose a person verification scheme using a novel combination of palmprint and speech. The crucial aspect of biometric based verification lies in its use of features in verification. Thus, in this paper, we propose two novel feature extraction methods for palmprint verification. The proposed methods are based on the Gaussian mixture model followed by subspace based approaches such as ICA I and ICA II, called independent component analysis I mixture model and independent component analysis (...)

    Mixture and chemical combination and related essays: A response to Robert Deltete and Anastasios Brenner.Paul Needham - 2004 - Foundations of Chemistry 6 (3):233-245.
    Robert Deltete and Anastasios Brenner have provided a thorough examination of my translation of Duhem’s Le mixte et la combinaison chimique (1902) and associated essays. I am very grateful for their efforts and gratified that such competent reviewers should be generally positive. They provide an overview of relevant aspects of Duhem’s life and work, which may serve to introduce him to readers of this journal and promote interest in Duhem studies. They also raise and answer some questions about the interpretation (...)
