|The Cognitive Mechanisms and Formal Models of Consciousness
Consciousness is the sense of self and the sign of life in natural intelligence. One of the profound myths in cognitive informatics, psychology, brain science, and computational intelligence is how consciousness is generated by physiological organs and neural networks in the bran. This paper presents a...
Image Compression Based on Generalized Principal Components Analysis and Simulated Annealing
Rafael Do Espírito Santo, Fabio Henrique Pereira, Edson Amaro Júnior.
The authors propose a new data dimensionality reduction method that is formulated as an optimization problem solved in two stages. In the first stage, Generalized Principal Component Analysis (GPCA) is used to find a solution with local maximum (local solution) whereas the algorithm Simulated Annealing...
The Cognitive Load Affects the Interaction Pattern of Emotion and Working Memory
Xuebing Li, Zhengzheng Ouyang, Yue-Jia Luo.
Emotion might selectively affect spatial and verbal cognitive activities and the selective interaction patter could be modulated by cognitive load. To test the hypotheses, the authors used event-related potentials (ERPs) technique to investigate the interaction pattern of emotion and working memory...
An Acquisition Model of Deep Textual Semantics Based on Human Reading Cognitive Process
Jun Zhang, Xiangfeng Luo, Lei Lu, Weidong Liu.
The acquisition of deep textual semantics is a key issue which significantly improves the performances of e-learning, web search and web knowledge services, etc. Though many models have been developed to acquire textual semantics, the acquisition of deep textual semantics is still a challenge issue....
Perspectives on the Field of Cognitive Informatics and its Future Development
Yingxu Wang, Bernard Carlos Widrow, Bo Zhang, Witold Kinsner, Kenji Sugawara, Fuchun Sun, Jianhua Lu, Thomas Weise, Du Zhang.
The contemporary wonder of sciences and engineering has recently refocused on the beginning point of: how the brain processes internal and external information autonomously and cognitively rather than imperatively like conventional computers. Cognitive Informatics (CI) is a transdisciplinary enquiry of...
Role-Based Human-Computer Interactions
Haibin Zhu, Ming Hou.
With increased understanding of cognitive informatics and the advance of computer technologies, it is becoming clear that human-computer interaction (HCI) is an interaction between two kinds of intelligences, i.e., natural intelligence and artificial intelligence. This paper attempts to clarify...
Main Retina Information Processing Pathways Modeling
Hui Wei, Qingsong Zuo, XuDong Guan.
In many fields including digital image processing and artificial retina design, they always confront a balance issue among real-time, accuracy, computing load, power consumption, and other factors. It is difficult to achieve an optimal balance among these conflicting requirements. However, human retina...
Songs to Syntax: Cognition, Combinatorial Computation, and the Origin of Language
Robert C. Berwick.
Language comprises a central component of a complex that is sometimes called “the human capacity.” This complex seems to have crystallized fairly recently among a small group in East Africa of whom people are all descendants. Common descent has been important in the evolution of the brain, such that...
Cognitive Memory for Semantic Agents Architecture in Robotic Interaction
Sébastien Dourlens, Amar Ramdane-Cherif.
Since 1960, AI researchers have worked on intelligent and reactive architectures capable of managing multiple events and acts in the environment. This issue is part of the Robotics domain. An extraction of meaning at different levels of abstraction and the decision process must be implemented in the...
Interactive Feature Visualization and Detection for 3D Face Classification
Jason McLaughlin, Shiaofen Fang, Sandra W. Jacobson, H. Eugene Hoyme, Luther Robinson, Tatiana Foroud.
A new visual approach to the surface shape analysis and classification of 3D facial images is presented. It allows the users to visually explore the natural patterns and geometric features of 3D facial scans to provide decision-making information for face classification which can be used for the...
A Novel Emotion Recognition Method Based on Ensemble Learning and Rough Set Theory
Yong Yang, Guoyin Wang.
Emotion recognition is a very hot topic, which is related with computer science, psychology, artificial intelligence, etc. It is always performed on facial or audio information with classical method such as ANN, fuzzy set, SVM, HMM, etc. Ensemble learning theory is a novelty in machine learning and...
Cognitive Informatics and Cognitive Computing in Year 10 and Beyond
Yingxu Wang, Robert C. Berwick, Simon Haykin, Witold Pedrycz, Witold Kinsner, George Baciu, Du Zhang, Virendrakumar C. Bhavsar, Marina L. Gavrilova.
Cognitive Informatics (CI) is a transdisciplinary enquiry of computer science, information sciences, cognitive science, and intelligence science that investigates into the internal information processing mechanisms and processes of the brain and natural intelligence, as well as their engineering...
Semantic Manipulations and Formal Ontology for Machine Learning based on Concept Algebra
Yingxu Wang, Yousheng Tian, Kendal Hu.
Towards the formalization of ontological methodologies for dynamic machine learning and semantic analyses, a new form of denotational mathematics known as concept algebra is introduced. Concept Algebra (CA) is a denotational mathematical structure for formal knowledge representation and manipulation in...
Text Semantic Mining Model Based on the Algebra of Human Concept Learning
Jun Zhang, Xiangfeng Luo, Xiang He, Chuanliang Cai.
Dealing with the large-scale text knowledge on the Web has become increasingly important with the development of the Web, yet it confronts with several challenges, one of which is to find out as much semantics as possible to represent text knowledge. As the text semantic mining process is also the...
In Search of Effective Granulization with DTRS for Ternary Classification
Bing Zhou, Yiyu Yao.
Decision-Theoretic Rough Set (DTRS) model provides a three-way decision approach to classification problems, which allows a classifier to make a deferment decision on suspicious examples, rather than being forced to make an immediate determination. The deferred cases must be reexamined by collecting...
Cognitive Dynamic Systems
The main topics covered in this paper address the following four issues: (1) Distinction between how adaptation and cognition are viewed with respect to each other, (2) With human cognition viewed as the framework for cognition, the following cognitive processes are identified: the perception-action...
A Modular Dynamical Cryptosystem Based on Continuous-Interval Cellular Automata
Jesus D. Terrazas Gonzalez, Witold Kinsner.
This paper presents a new cryptosystem based on chaotic continuous-interval cellular automata (CCA) to increase data protection as demonstrated by their flexibility to encrypt and decrypt information from distinct sources. Enhancements to cryptosystems are also presented including (i) a model based on...
Time and Frequency Analysis of Particle Swarm Trajectories for Cognitive Machines
Dario Schor, Witold Kinsner.
This paper examines the inherited persistent behavior of particle swarm optimization and its implications to cognitive machines. The performance of the algorithm is studied through an average particle’s trajectory through the parameter space of the Sphere and Rastrigin function. The trajectories are...
On Machine Symbol Grounding and Optimization
From the point of view of an autonomous agent the world consists of high-dimensional dynamic sensorimotor data. Interface algorithms translate this data into symbols that are easier to handle for cognitive processes. Symbol grounding is about whether these systems can, based on this data, construct...
