在人脸识别中，传统有效的鉴别分析方法需要更多样本评估类内散度信息，由于人脸的单样本问题，导致某些经典的方法，如Fisherface和Eigenface等失效。解决的方法通常是生成各种虚拟样本来扩充训练集来实施这些算法。针对这个问题，根据人脸的对称相似理论，人脸样本的相关变化信息可以从它的对称脸上提取，提出组合原始训练样本及它的虚拟平均脸、对称脸作为训练样本集，应用稀疏理论进行加权积分融合，分两步进行识别的方法。并在ORL和FERET人脸数据库做了对比实验，根据实验结果表明本方法比现有一些突出效果人脸识别方法更好，并具有一定的鲁棒性。

This pilot study tests the effects on individual performance of dyadic versus individual practice in a 3D virtual world (VW) home safety assessment. Sixty medical students in three conditions (dyadic spatially separated with paired avatars DPA; individual with avatar IND; and dyadic spatially together with single avatar DSA) participated in a geriatric home safety simulation. The participants, via avatars, conducted an assessment of physical hazards. Participants then worked individually in a separate 3D VW home assessment. Dyadic practice, spatially together with a single avatar (DSA), improved individual performance in the subsequent 3D VW home assessment.

In this paper, we apply a Hidden Markov Model (HMM) to analyze time-series personal health checkup data. HMM is widely used for data having continuation and extensibility such as time-series health checkup data. Therefore, using HMM as probabilistic model to model the health checkup data is considered to be suitable, and HMM can express the process of health condition changes of a person. In this paper, a HMM with six states placed in a 2×3 matrix was prepared. We collected training features including the time-series health checkup data. Each feature consists of eight inspection parameters such as BMI, SBP, and TG. The HMM was then built using the training features. In the experiments, we built five HMMs for different gender and age conditions (e.g. male 50's) using thousands of training feature vectors, respectively. Investigating the HMMs we found that the HMMs can model three health risk levels. The models can also represent health transitions or changes, indicating the possibility of estimating the risk of lifestyle-related diseases.

Our objective was to enable an end-user to create complex queries to drug information sources through functional composition, by creating sequences of functions from application program interfaces (API) to drug terminologies. The development of a functional composition model seeks to link functions from two distinct APIs. An ontology was developed using Protege to model the functions of the RxNorm and NDF-RT APIs by describing the semantics of their input and output. A set of rules were developed to define the interoperable conditions for functional composition. The operational definition of interoperability between function pairs is established by executing the rules on the ontology. We illustrate that the functional composition model supports common use cases, including checking interactions for RxNorm drugs and deploying allergy lists defined in reference to drug properties in NDF-RT. This model supports the RxMix application , an application we developed for enabling complex queries to the RxNorm and NDF-RT APIs.
