关键词： Single sample per person   Face recognition   Decision pyramid classifier   Image partitioning   Feature extraction  

摘要： The single sample per person (SSPP) problem is a great challenge for real-world face recognition systems. In an SSPP scenario, there is always a large gap between a normal sample enrolled in the gallery set and the non-ideal probe sample. In this paper, we propose a new face recognition method, called decision pyramid classifier (DPC), to solve SSPP problems with large appearance variations (e.g., illumination, expression and partly occlusions). Unlike the conventional image partitioning methods, the proposed DPC is a nonparametric method which does not require a training process. In the data preprocessing phase of DPC, we divide each training image into multiple non-overlapping local blocks and respectively extract features from each block to generate the training feature set. For an unseen image, DPC requires obtaining its features using the exactly same preprocessing. By constructing a decision pyramid, we predict the final category of the unseen face image. Experimental results show that DPC possesses higher recognition rate than other related face recognition methods.

摘要： Mobile instant messaging is the communication technology revolution that is changing the way people communicate. The adoption rate is surging and the massive growth is experienced worldwide. Prior studies on instant messaging have been primarily concerned with its task-relevant or functional aspects, while less attention is paid to social interaction aspects. Drawing from media richness theory, present research highlights that social interaction factors can be facilitated by an enriched communication channel to create closer interpersonal social relationships. Specifically, the findings illustrate that the combined effect of text messaging and emoticon use increases information richness, which leads to perceived playfulness in mobile instant messaging. In addition, the perceived playfulness fostered in the instant messaging process plays a driving role in facilitating social connectedness, identity expressiveness between users and advocacy of mobile instant messaging usage.

摘要： Introduction This paper illustrates the use of cohort data from a population to describe the early life prevalence and odds ratios (ORs) of the main classes of International Classification of Diseases (ICD) associated with any mental disorder arising at any time during the 16 year study period. Objectives The main ICD disorder classes were examined in relation to psychiatric disorders over 16 years in a cohort under the age of two years between April 1st, 1993, and January 1st, 1995. Aims To demonstrate the utility of studying the complete profile of associated diagnoses over time in a population cohort. Methods The total number of individuals under the age of two years before 1995 (n = 17,603) were tallied within each main class of ICD disorder by year and expressed as ORs of those with and without any 16-year psychiatric disorder. Results The greatest annual rates observed in the early years of life were for the following main ICD classes of disease: respiratory system, sense organs, symptoms signs ill-defined conditions, no diagnosis, injury poisoning, and skin subcutaneous tissue disorders. These disorders also had the highest ORs in early life given the presence of a mental disorder at any time during the study period. Discussion Knowing the early life main class diagnoses associated with psychiatric disorders could guide both basic science research as well as early intervention social and health investment policies.
