In this paper, we investigate the power of online learningin stochastic network optimization with unknown systemstatistics a prior. We are interested in understanding howinformation and learning can be efficiently incorporated intosystem control techniques, and what are the fundamentalbenefits of doing so. We propose two Online Learning-AidedControl techniques, OLAC and ...

We propose an extension of the branching time transforma tion which can handle a signi cantly broader class of Datalog pro grams The initial transformation could only be applied to Chain Data log a useful but restricted class of programs In this paper we demon strate that the transformation of can be extended to handle all Datalog programs that do not allow multiple consumptions of variables in...

Most decision tree algorithms focus on uni variate i e axis parallel tests at each inter nal node of a tree Oblique decision trees use multivariate linear tests at each non leaf node This paper reports a novel approach to the construction of non linear decision trees The crux of this method consists of the gen eration of new features and the augmenta tion of the primitive features with these ne...

A paper read to a Conference of Physicians of the South-East Metropolitan Region at the Brook Hospital, March I7, I962. strate the value of this in a case of pulmonary valvular stenosis. (ii) Intensification of the fluoroscopic image with television monitoring. This assists in screening and the placement of catheters and avoids the necessity for dark adaptation and darkening of the screening ro...

When testing a system modelled as a nite state machine it is de sirable to minimize the e ort required Yang and Ural demon strate that it is possible to utilize test sequence overlap in order to reduce the test e ort and Hierons represents this overlap by us ing invertible transitions In this paper invertibility will be extended to sequences in order to further reduce the test e ort and encapsu...

Understanding how proteins facilitate signaling and sub-strate transport across biological membranes is an important frontier of structural biology. Membrane proteins are the doors and windows of cells: many membrane proteins are gates of entry into or exit from cells or cellular compartments, and others allow cells to sense their environment. One important multifunctional family of membrane pr...

We present an e cient method for segmenting colour images which may be utilised in several robotic vision tasks It categorises pixels according to their percep tual colour by exploiting the chromaticity contained in the signal of a standard colour camera as an in dex into a pre clustered chromaticity plane A tech nique called perceptual colour grouping is introduced to prevent oversegmentation ...
