We propose a new reinforcement learning (RL) algorithm for contextual Markov decision processes (CMDP) using spectral methods. CMDPs are structured MDPs where the dynamics and rewards depend on a smaller number of hidden states or contexts. If the mapping between the hidden and observed states is known a priori, then standard RL algorithms such as UCRL are guaranteed to attain low regret. Is it...
Image formation from squinted sliding spotlight synthetic aperture radar (SAR) is limited by azimuth spectral folding and severe two dimension coupling. This paper presents an Extended Wavenumber Domain Algorithm (WDA) for highly squinted sliding spotlight SAR data processing. This algorithm adopts azimuth deramping approach to overcome the azimuth spectral folding phenomenon. The chirp rate fo...
Future multiphoton applications of quantum optics and quantum information science require quantum memories that simultaneously store many photon states, each encoded into a different optical mode, and enable one to select the mapping between any input and a specific retrieved mode during storage. Here we show, with the example of a quantum repeater, how to employ spectrally multiplexed states a...
Vegetation studies helps to develop a profile on extensive areas affected by vegetation changes. Image processing techniques does manipulation of digital images for various applications. The satellite image processing is increasingly used for vegetation mapping. Now a day‟s both multi spectral sensors and hyper spectral sensors are used for vegetation monitoring. General Terms Remote sensing, V...
Imaging spectrometer data (also known as 'hyperspectral imagery' or HSI) are well established for detailed mineral mapping from airborne and satellite systems. Overhead data, however, have substantial additional potential when used together with ground-based measurements. An imaging spectrometer system was used to acquire airborne measurements and to image in-place outcrops (mine walls) and box...
