In model selection procedures in supervised learning, a model is usually chosen so that the expected test error over all possible test input points is minimized. On the other hand, when the test input points (without output values) are available in advance, it is more effetive to choose a model so that the test error only at the test input points at hand is minimized. In this paper, we follow t...

We designed and implemented a gaze-controlled drawing application that utilizes modifiable and movable shapes. Moving and resizing tools were implemented with gaze gestures. Our gaze gestures are simple one-segment gestures that end outside the screen. Also, we use the closure of the eyes to stop actions in the drawing application. We carried out an experiment to compare gaze gestures with a dw...

A visual speller is a brain–computer interface that empowers users with limitedmotor functionality to input text into a computer by measuring their electroencephalographic responses to visual stimuli. Most prior research on visual spellers has focused on input of alphabetic text. Adapting a speller for other types of segmental or syllabic script is straightforward because such scripts comprise ...

In this paper we discuss the use of the Bayesian posterior probability distribution over weight space and Receiver Operating Characteristic curves in a neural network input selection algorithm. The a posteriori distribution is obtained by combining the likelihood function based on training data and a prior distribution based on expert knowledge. To numerically calculate the marginalization, Mar...

The short-term load forecasting is an essential problem in energy system planning and operation. The accuracy of the forecasting models depends on the quality of the input information. The input variable selection allows to chose the most informative inputs which ensure the best forecasts. To improve the short-term load forecasting model based on the kernel regression four variable selection wr...

Multiple-input multiple-output (MIMO) systems have an advantage of spectral efficiency compared to single-input single-output systems, which means that the MIMO systems have significantly higher data throughput. The VBLAST (Vertical Bell Laboratories Layered Space Time) scheme is a popular transceiver structure which has relatively good performance. In the V-BLAST scheme, ordered successive int...

We have developed a menu-selection-based Japanese input method for a pen device. To obtain user-input kanji-form text rapidly, the system requires sequence of consonant. Following this, the user selects kanji-form candidates inferred by the system. In some situations, consonant sequences can trigger an explosion of kanji-form candidates. Therefore, we have implemented a method for reducing cand...

objectives: in present study, we studied the effect of teaching three painting methods (free method, subject selection method and complementary method) on creativity of children with learning disabilities. first, among all disabled students, who refer to bizhani center for learning disabilities in arak city, 60 subjects were randomly selected as statistical sample. thus, the 45 children, divide...
