Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Probabilistic HIV Recency Classification -- A Logistic Regression without Labeled Individual Level Training Data
概率 HIV新近度分类 个人水平训练数据 逻辑回归
2023/4/24
Accurate HIV incidence estimation based on individual recent infection status (recent vs long-term infection) is important for monitoring the epidemic, targeting interventions to those at greatest ris...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On the classification of entire solutions to the critical p-Laplace equation
临界 p-拉普拉斯方程 整个解 分类
2023/5/9
In this talk, we will focus on the classification of positive solutions to the critical p-Laplace equation. It is well known that such issue is crucial in many applications such as a priori estimates,...

Basic Hopf Algebras of Finite Representation Type and Their Classification
Basic Hopf Algebras Finite Representation Type Their Classification
2018/4/20
Let k be a algebraically closed field. We give a necessary and sufficient condition for a basic Hopf algebra over k to be finite representation type. Explicitly, we prove that a basic Hopf algebra ove...
This paper contains two main results. The first is the existence of an equivariant WeilPetersson geodesic in Teichm¨ uller space for any choice of pseudo-Anosov mapping class. As a consequence one obt...

Discriminant Adaptive Nearest Neighbor Classification
lassification nearest neighbors linear discriminant an,alysis,curse of dimensionality
2015/8/21
earest neighbor classification expects the class conditional probabilities to be locally constant,and suffers from bias in high dimensions. We propose a locally adaptive form of nearest neighbor class...
The Sentimental Factor:Improving Review Classification via Human-Provided Information
Sentimental Factor Review Classification Human-Provided Information
2015/8/21
Sentiment classification is the task of labeling a review document according to the polarity of its prevailing opinion (favorable or unfavorable). In approaching this problem, a model builder often ha...
Margin trees for high-dimensional classification
Maximum margin classifier supprt vector machine decision tree CART
2015/8/21
We propose a method for the classification of more than two classes, from high-dimensional features. Our approach is to build a binary decision tree in a top-down manner, using the optimal margin clas...
Pareto optimal linear classification
Linear classifier probability weigh gaussian distribution
2015/8/10
We consider the problem of choosing a linear classifier that minimizes misclassification probabilities in two-class classification, which is a bi-criterion problem, involving a trade-off between two o...

Automatic Classification of Early Parkinson’s Disease with Multi-Modal MR Imaging
Automatic Classification Early Parkinson’s Disease Multi-Modal MR Imaging
2018/4/19
Background: In recent years, neuroimaging has been increasingly used as an objective method for the diagnosis of Parkinson’s disease (PD). Most previous studies were based on invasive imaging modaliti...
Classification in postural style
Aggregation classification cross-validation postural style targeted minimum loss learning(TMLE) top-scoring pairs classifier super-learning
2012/11/23
This article contributes to the search for a notion of postural style, focusing on the issue of classifying subjects in terms of how they maintain posture. Longer term, the hope is to make it possible...
A Fast Classification Method for Single-Particle Projections with a Translation and Rotation Invariant
Classification Fourier transform Translationand rotation invariant Secondary-class.
2012/8/7
The aim of the electron microscopy image classification is to categorize the projection
images into different classes according to their similarities. Distinguishing images
usually requires that the...
Angles and a Classification of Normed Spaces
generalized angle normed space Functional Analysis
2012/7/9
We suggest a concept of generalized `angles' in arbitrary real normed vector spaces. We give for each real number a definition of an `angle' by means of the shape of the unit ball. They all yield the ...
