Conference on Image Reconstruction from Incomplete Data
作者: Doerschuk, PC Johnson, JE Purdue Univ Sch Elect & Comp Engn W Lafayette IN 47907 USA
A statistical model for the object and the complete image formation process in cryo electron microscopy of viruses is presented. Using this model, maximum likelihood reconstructions of the 3D structure of viruses are ... 详细信息

Parametric hidden Markov models for gesture recognition
收藏 引用
IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE 1999年 第9期21卷 884-900页
作者: Wilson, AD Bobick, AF MIT Media Lab Vis & Modeling Grp Cambridge MA 02139 USA Georgia Inst Technol Coll Comp Atlanta GA 30332 USA
A new method for the representation, recognition, and interpretation of parameterized gesture is presented. By parameterized gesture we mean gestures that exhibit a systematic spatial variation;one example is a point ... 详细信息

Exploring heterogeneity in randomized trials via meta-analysis
收藏 引用
DRUG INFORMATION JOURNAL 1999年 第1期33卷 211-224页
作者: Schmid, CH New England Med Ctr Biostat Res Ctr Boston MA 02111 USA Tufts Univ Sch Med Boston MA 02111 USA
Meta-analysis of clinical trials with heterogeneous results provides an opportunity to learn a great deal about variations in treatment effectiveness. Rather than computing a single summary estimate of-a series of tri... 详细信息

Statistical modeling of total phosphorus concentrations measured in south Florida rainfall
收藏 引用
ECOLOGICAL MODELLING 1999年 第1期116卷 33-44页
作者: Ahn, H S Florida Water Management Dist Resources Assessment Div W Palm Beach FL 33406 USA
Atmospheric deposition can be a significant source of phosphorus to South Florida's aquatic system. The weekly total phosphorus (TP) concentrations in rainfall have been measured routinely in the region since 1974... 详细信息

Hierarchical adaptive Kalman filtering for interplanetary orbit determination
收藏 引用
IEEE TRANSACTIONS ON AEROSPACE AND ELECTRONIC SYSTEMS 1998年 第3期34卷 883-896页
作者: Chaer, WS Bishop, RH Ghosh, J Univ Texas Dept Aerosp Engn & Engn Mech Austin TX 78712 USA Univ Texas Dept Elect & Comp Engn Austin TX 78712 USA
A modular and flexible approach to adaptive Kalman filtering has recently been introduced using the framework of a mixture-of-experts regulated by a gating network. Each expert is a Kalman biter modeled with a differe... 详细信息

An algorithm for maximum likelihood estimation of hidden Markov models with unknown state-tying
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1998年 第1期6卷 61-70页
作者: Cappe, O Mokbel, CE Jouvet, D Moulines, E ENST Dept Signal CNRS URA 820 F-75634 Paris 13 France
For speech recognition based on hidden Markov modeling, parameter-tying, which consists in constraining some of the parameters of the model to share the same value, has emerged as a standard practice. In this paper, a... 详细信息

Recursive dimensionality reduction using Fisher's Linear Discriminant
收藏 引用
PATTERN RECOGNITION 1998年 第7期31卷 881-888页
作者: Poston, WL Marchette, DJ NSWCDD Dahlgren VA 22448 USA
Dimensionality reduction is an important part of the pattern recognition process. It would be very useful to have a recursive form for dimensionality reduction that is suitable for implementation on massive data sets ... 详细信息

Choice model analysis of the "pick any/n" type of binary data
收藏 引用
JAPANESE PSYCHOLOGICAL RESEARCH 1998年 第1期40卷 31-39页
作者: Takane, Y McGill Univ Dept Psychol Montreal PQ H3A 1B1 Canada
In the "pick any/n" method, subjects are asked to choose any number of items from a list of n items according to some criterion. This kind of data can be analyzed as a special case of either multiple-choice ... 详细信息
