Word representation is one of the basic word repressentation methods in natural language processing, which mapped a word into a dense real-valued vector space based on a hypothesis: words with similar context have similar meanings. Models like NNLM, C&W, CBOW, Skip-gram have been designed for word embeddings learning, and get widely used in many NLP tasks. However, these models assume that one...
For the problem of lacking efficient regulation mechanism between local search and global search in an evolution algorithm based on cloud model (CEBA), a competitive-cooperative co-evolutionary optimization algorithm based on cloud model (CECD) is proposed in this paper. It introduces the concept of co-evolution in biological systems into intelligent computing. The proposed algorithm makes cooperation...
Because of the special position of electric power industry in national economy and social life, electric power information security has been given particular attention. For lack of the theory basis of the security area classification and the access strategy between security areas in power grid enterprise, a new classification and protection method based on network business security for power grid...
An improved PSO algorithm which is applied to mobile robot path planning is proposed. In this paper, we use the grid method to decompose two-dimensional space of the robot path to build the path space model. Using this method is simple and easy to achieve computer modeling, storing, processing, updating and analyzing. It can make the pairs of particles in the algorithm exchange information by leading...
Taking the Knightian uncertainty of financial market into consideration, the randomness and fuzziness of stock price should been evaluated by both probabilistic expectation and fuzzy expectation. We make use of parabolic type fuzzy numbers to discuss the fuzzy binomial option pricing model with uncertainty of both randomness and fuzziness, and derive expression for the fuzzy risk neutral probabilities,...
Designing an all-electric ship (AES) requires testing of the interaction between hundreds of interconnected power electronic subsystems built by different manufacturers. Such integration tests require large analog test benches or the use of actual equipment during system commissioning. Fully digital simulators can also be used to perform Hardware-in-the-Loop (HIL) integration tests to evaluate the...
