As one of the most popular methods for image segmentation, fuzzy C-means algorithm suffers two unavoidable initialization difficulties including obtaining initial cluster centroids and deciding cluster number, which affect the algorithm performance. Motivated by the above, an automatic fuzzy clustering algorithm is proposed in this paper, where observation matrix, judgment matrix and set partitioning...
With the exponential growth in continuous data streams, real time streaming processing has been gaining a lot of popularity. Spark Streaming is one of the open source frameworks for reliable, high-throughput and low latency stream processing. Though it is a near real time stream processing framework running on commodity hardware, real time event processing is not guaranteed in its scheduling system...
For systems with multiple time delays, a novel state and sensor noise observer is designed to estimate system states and sensor noises at the same time. In this design, descriptor system approach and linear matrix inequality technique are adopted. Unbounded sensor faults will make the system fail unavoidably, it is indispensable to derive a reliable control scheme against sensor failures. Using the...
