The paper discusses the basic principles and the architecture of the software toolkit for constructing knowledge-based systems which can be used cooperatively over computer networks and also embedded into larger software systems in different ways. Presented architecture is based on frame knowledge representation and production rules, which also allows to interface high-level programming languag...

The representation of navigable space, consisting of multiple interconnected spaces, yet is not well understood. We examined different levels of integration within memory (local, regional, global). Participants learned two distinctive regions of a virtual environment that converged at a common transition-point. Subsequently, we tested their memory with a pointing task, varying body alignment du...

the generalization of p-frame in banach spaces is considered in this paper. the concepts of an $tilde{x}$-frame and a system conjugate to $tilde{x}$-frame were introduced. analogues of the results on the existence of conjugate system were obtained. the stability of $tilde{x}$-frame having a conjugate system is studied.

Modal logic plays an important role in various areas of computer science, including verification and knowledge representation. In many practical applications it is natural to consider some restrictions of classes of admissible frames. Traditionally classes of frames are defined by modal axioms. However, many important classes of frames, e.g. the class of transitive frames or the class of Euclid...

Approximately dual frames are studied in the Hilbert space setting. Approximate duals are easier to construct than classical dual frames, and can be tailored to yield almost perfect reconstruction. Bounds on the deviation from perfect reconstruction are obtained for approximately dual frames constructed via perturbation theory. An alternative bound is derived for the rich class of Gabor frames,...

Semi-supervised video object segmentation (VOS) refers to segmenting the target in remaining frames given its annotation first frame, which has been actively studied recent years. The key challenge lies finding effective ways exploit spatio-temporal context of past help learn discriminative representation current frame. In this paper, we propose a novel Siamese network with specifically designe...

Efficient representation of the background texture in video image frames, motivates compression strategies based on good perceptual reconstruction quality, instead of just bit-accurate reconstruction. This is especially true for video image frames in applications such as videos with structural patterns, and Bi-Directional Reflectance Distribution Function (BRDF) image frames of an object, where...

In this position paper, we present a proposal for a layered architecture for a hybrid object-based representation system, relying on two kinds of representation formalisms, namely description logics and frame knowledge representation systems or framebased systems I. In description logics, concepts, roles and individuals represent real-world concepts, their properties and their instances. The su...
