This paper presents computational support for the Clock Drawing Test (CDT), a simple cognitive dysfunction diagnosis tool. Despite its popularity of current use, the CDT has been administered the same way for the past three decades as a pencil-and-paper test. By making a computerized drawing test, we can understand the process of clock drawing construction(More)
Early detection of cognitive impairment can prevent or delay the progress of cognitive dysfunction. In the field of neurology, the Clock Drawing Test (CDT) is one of the most popular instruments for detecting cognitive impairment. This paper presents the development of the ClockReader system, a computerized Clock Drawing Test. The main function of the(More)
This paper introduces a new approach to dictionary-based source separation employing a learned non-linear metric. In contrast to existing parametric source separation systems, this model is able to utilize a rich dictionary of speech signals. In contrast to previous dictionary-based source separation systems, the system can utilize perceptually relevant(More)
This paper utilizes a recently introduced non-linear dictionary-based denoising system in another voice mapping task, that of transforming low-bandwidth, low-bitrate speech into high-bandwidth, high-quality speech. The system uses a deep neural network as a learned nonlinear comparison function to drive unit selection in a concatenative synthesizer based on(More)
BACKGROUND/AIMS The purpose of this study was to investigate the malignant potential of aberrant crypt foci (ACF) by measuring the multiplicity of crypts and lectin expression in the early and late stages of 1,2-dimethylhydrazine (DMH)-induced colon carcinogenesis. METHODS Six-week-old Wistar rats were injected subcutaneously with DMH for 27 weeks. We(More)

PURPOSE Inhalation injury is one of the most severe morbidity and mortality factors in burn patients. The purpose of this study is to analyze the impact of inhalation injury to the prognosis of burn patients and to investigate the relationship between the inhalation injury assessment and the prognosis of patients. METHODS Bronchoscopy was performed in 170(More)
In this paper, we propose a new recognition algorithm for handwritten digit recognition. This algorithm is designed to enhance the recognition accuracy of current Microsoft SDK recognizer. The algorithm recognizes the unique signature of each number by comparing curved and straight lines, and writing sequences of the stroke. Through the trial experiments,(More)
