Nowadays images on social networking websites (e.g., Flickr) are mostly accompanied with user-contributed tags, which help cast a new light on the conventional content-based image analysis tasks such as image classification and retrieval. In order to establish a scalable social image analysis system, two issues need to be considered: 1) Supervised learning is a futile task in modeling the enorm...

Fisher score and Laplacian score are two popular feature selection algorithms, both of which belong to the general graph-based feature selection framework. In this framework, a feature subset is selected based on the corresponding score (subset-level score), which is calculated in a trace ratio form. Since the number of all possible feature subsets is very huge, it is often prohibitively expens...

This “activated” state of the nucleosome is Stanford School of Medicine dependent on the presence of the chromatin-remodelStanford, California 94305 ing complex but not on continuing ATP hydrolysis...

IN its eight years, the IEEE Transactions on Affective Computing (TAC) has witnessed a time of great opportunities for the field: Artificial Intelligence (AI) and Machine Learning have recently made great progress increasing the distribution and usage of intelligent solutions in the greater public and commercial world. This progress bears many great chances for Affective Computing, as with incr...

We examined the effect of a range of pentobarbital concentrations on 0.5 mM g-aminobutyric acid (GABA)-activated channels (10 6 1 pS) in inside-out or outside-out patches from rat cultured hippocampal neurons. The conductance increased from 12 6 4 to 62 6 9 pS as the pentobarbital concentration was raised from 10 to 500 mM and the data could be fitted by a Hill-type equation. At 100 mM pentobar...

Sparse learning has been proven to be a powerful technique in supervised feature selection, which allows to embed feature selection into the classification (or regression) problem. In recent years, increasing attention has been on applying spare learning in unsupervised feature selection. Due to the lack of label information, the vast majority of these algorithms usually generate cluster labels...

RANDOM SUBSPACE METHOD IN CLASSIFICATION AND MAPPING OF FMRI DATA PATTERNS Tianwen Chen, PhD George Mason University, 2011 Dissertation Director: Dr. Daniel E. Houser The functional magnetic resonance imaging (fMRI) technique is widely used in studying human brain functions. It measures brain activities both spatially and temporally. The past decade has witnessed a growing interest in the fMRI ...

We are developing a hand-printed character recognition system using a multilayered neural net trained through backpropagation. We report on results of training nets with samples of hand-printed digits scanned off of bank checks and hand-printed letters interactively entered into a computer through a stylus digitizer. Given a large training set, and a net with sufficient capacity to achieve high...

Cereal Chern. 65(3):215-222 Zein, the major alcohol-soluble protein of corn endosperm, was extracted with 55% 2-propanol. It was then fractionated by preparative reversed-phase (CIs) high-performance liquid chromatography (RPH PLC) with an acetonitrile-triOuoroacetic acid gradient. From 15 to 17 peaks resulted for native or reduced and alkylated (R-A) zeins. Sodium dodecyl sulfate-polyacrylamid...
