The decomposition-based multiobjective evolutionary algorithms (MOEAs) generally make use of aggregation functions to decompose a optimization problem into multiple single-objective problems. However, due the nature contour lines for adopted functions, they usually fail preserve diversity in high-dimensional objective space even by using diverse weight vectors. To address this problem, we propose maintain desired solutions their process explicitly exploiting perpendicular distance from...
Multicomponent therapeutics offer bright prospects for the control of complex diseases in a synergistic manner. However, finding ways to screen combinations from numerous pharmacological agents is still an ongoing challenge. In this work, we proposed first time “network target”-based paradigm instead traditional "single target"-based virtual screening and established algorithm termed NIMS (Network target-based Identification Synergy) prioritize agent high throughput way. treats...
This paper conducts a formal study of the shot boundary detection problem. First, general framework techniques is proposed. Three critical techniques, i.e., representation visual content, construction continuity signal and classification values, are identified formulated in perspective pattern recognition. Meanwhile, major challenges to identified. Second, comprehensive review existing approaches conducted. The representative categorized compared according their roles framework. Based on...
Nowadays, cameras equipped with AI systems can capture and analyze images to detect people automatically. However, the system make mistakes when receiving deliberately designed patterns in real world, i.e., physical adversarial examples. Prior works have shown that it is possible print patches on clothes evade DNN-based person detectors. these examples could catastrophic drops attack success rate viewing angle (i.e., camera's towards object) changes. To perform a multi-angle attack, we...
Traditional relation extraction methods require pre-specified relations and relation-specific human-tagged examples. Bootstrapping systems significantly reduce the number of training examples, but they usually apply heuristic-based to combine a set strict hard rules, which limit ability generalize thus generate low recall. Furthermore, existing bootstrapping do not perform open information (Open IE), can identify various types without requiring pre-specifications. In this paper, we propose...
As a special topic in computer vision, fine-grained visual categorization (FGVC) has been attracting growing attention these years. Different with traditional image classification tasks which objects have large inter-class variation, the concepts datasets, such as hundreds of bird species, often very similar semantics. Due to similarity, it is difficult classify without locating really discriminative features, therefore becomes more important for algorithm make full use part information...
In this paper, we demonstrate that the essentials of image classification and retrieval are same, since both tasks could be tackled by measuring similarity between images. To end, propose ONE (Online Nearest-neighbor Estimation), a unified algorithm for retrieval. is surprisingly simple, which only involves manual object definition, regional description nearest-neighbor search. We take advantage PCA PQ approximation GPU parallelization to scale our up large-scale Experimental results verify...
Interpretability of deep neural networks (DNNs) is essential since it enables users to understand the overall strengths and weaknesses models, conveys an understanding how models will behave in future, diagnose correct potential problems. However, challenging reason about what a DNN actually does due its opaque or black-box nature. To address this issue, we propose novel technique improve interpretability DNNs by leveraging rich semantic information embedded human descriptions. By...
Interpretability of a deep neural network aims to explain the rationale behind its decisions and enable users understand intelligent agents, which has become an important issue due importance in practical applications.

Adversarial attacks can easily fool object recognition systems based on deep neural networks (DNNs). Although many defense methods have been proposed in recent years, most of them still be adaptively evaded. One reason for the weak adversarial robustness may that DNNs are only supervised by category labels and do not part-based inductive bias like process humans. Inspired a well-known theory cognitive psychology – recognition-by-components, we propose novel model ROCK (Recognizing Object...

In this paper, we tackle problem propose search framework which operates like searching text documents. Noteworthy for its adoption the well-founded principles, first selects few related query, by employing tf-idf scheme, called c-tf-idf, measure informativeness These selected form...
Abstract Background Drug combination therapy is commonly used in clinical practice. Many methods including Bliss independence method have been proposed for drug design based on simulations models or experiments.

Exploration system structure becomes important reduce complexity problem. Results In this paper, we deduced mathematical model which simplify...
Min-wise hash is a widely-used hashing method for scalable similarity search in terms of Jaccard similarity, while practice it necessary to compute many such functions certain precision, leading expensive computational cost. In this paper, we introduce an effective method, i.e. the min-max which significantly reduces time by half, yet has provably slightly smaller variance estimating pair wise similarity. addition, estimator only contains equality checking, thus especially suitable...

Numerous methods have been proposed achieve better results. However, we find previous are not reliable enough provide meaningful interpretation through simple sanity check: required explain output non-maximum prediction classes, which usually ground-truth classes. For example, let an image "dog" given wrong class label...
