The ability to transfer knowledge across tasks is important in guaranteeing the performance of lifelong learning in autonomous agents. We propose a flexible Bayesian Nonparametric (BNP) model based architecture for transferring knowledge between reinforcement learning domains. A Dependent Dirichlet Process Gaussian Process hierarchial BNP model is used to cluster different classes of source MDP...

R.Sumalatha, M.V.Subramanyam Abstract— In this paper we propose an efficient region of interest (ROI) coding technique based on multiwavelet transform, set partitioning in hierarchial (SPIHT) algorithm of medical images. This new method reduces the importance of background coefficients in the ROI code block without compromising algorithm complexity. By using this coding method the compressed bi...

Hierarchical A∗ (HA∗) uses of a hierarchy of coarse grammars to speed up parsing without sacrificing optimality. HA∗ prioritizes search in refined grammars using Viterbi outside costs computed in coarser grammars. We present Bridge Hierarchical A∗ (BHA∗), a modified Hierarchial A∗ algorithm which computes a novel outside cost called a bridge outside cost. These bridge costs mix finer outside sc...

Purpose: The purpose of this study was to analyze the influence risk for post-traumatic stress disorder (PTSD risk), social stigma, and support on quality life COVID-19 survivors.Methods: Data were collected from 180 survivors who discharged hospital September 1 December 31, 2021. Structured questionnaires used assess variables. Collected data analyzed using SPSS/WIN 27.0, with independent t-te...

In this paper we introduce the representative object, which uncovers the inherent schema(s) in semistructured, hierarchical data sources and provides a concise description of the structure of the data. Semistructured data, unlike data stored in typical relational or object-oriented databases, does not have fixed schema that is known in advance and stored separately from the data. With the rapid...

Securing ad hoc networks represents a challenging issue, related to their very characteristics of decentralized architecture, low-complexity, and multiple hops communications. Even if several methods are available, this paper presents a novel approach to allow secret sharing of information at lower levels of the node protocol stack. In fact, secret sharing schemes provide a natural way of addre...

BACKGROUND & OBJECTIVES Diagnosis for Mycoplasma pneumoniae usually relies on serological tests. PCR technology has some advantages but also limitations. The optimal selection for these tests still needs discussion. This paper reviews the overall diagnostic accuracy of PCR versus serological assays for diagnosis of M. pneumoniae infections and to identify factors associated with heterogeneity o...

The tissue-separating capacity of chondral structures has been debated for more than 30 years, and one aspect that has particularly been questioned is whether the secondary cartilage of the mandibular condyle is comparable to primary growth cartilage, e.g. the epiphyseal growth plate. The present report summarizes information gained by using a specific interosseal transplantation method. These ...
