Bài viết mô hình nhận dạng mẫu từ đơn tiếng Việt được trình bày. Tiếng nói được trích đặc trưng bằng giải thuật MFCC (Mel-Frequency Cepstral Coefficients). Giải thuật thời gian động DTW (Dynamic Time Warping) được sử dụng để so sánh tiếng nói đầu vào với các mẫu thu sẵn, từ đó sẽ chọn ra được kết quả nhận dạng phù hợp nhất với tiếng nói phát ra. Mời các bạn cùng tham khảo!

Bài viết đề xuất phương pháp nhận dạng ngôn ngữ ký hiệu tiếng Việt cử chỉ động với dữ liệu được thu từ camera Kinect phiên bản 2. Việc xác định mức độ tương đồng giữa hai cử chỉ được thực hiện bởi thuật toán Dynamic Time Warping (DTW) và kết quả phân lớp được đưa ra bởi Nearest Neighbor (NN). Việc thực nghiệm trên 10 từ tiếng Việt mang lại hiệu quả nhận dạng trung bình lên đến 92%, đồng thời hệ thống có thể xử lý theo thời gian thực nhằm phù hợp với ứng dụng thực tế.

Technological limitations have hindered the large-scale genetic investigation of tandem repeats in disease. We show that long-read sequencing with a single Oxford Nanopore Technologies PromethION flow cell per individual achieves 30× human genome coverage and enables accurate assessment of tandem repeats including the 10,000-bp Alzheimer’s disease-associated ABCA7 VNTR.

Functional genomic and epigenomic research relies fundamentally on sequencing based methods like ChIP-seq for the detection of DNA-protein interactions. These techniques return large, high dimensional data sets with visually complex structures, such as multi-modal peaks extended over large genomic regions.

This paper presents a human action recognition method using dynamic time warping and voting algorithms on 3D human skeletal models. In this method human actions, which are the combinations of multiple body part movements, are described by feature matrices concerning both spatial and temporal domains.

Time series forecasting based on pattern matching has received a lot of interest in the recent years due to its simplicity and the ability to predict complex nonlinear behavior. In this paper, we investigate into the predictive potential of the method using k-NN algorithm based on R*-tree under dynamic time warping (DTW) measure.

In this paper we present the Einstein equation extended in six-dimensions (6D) from the formalism of codimension-2 brane, which is created by a 4-brane and 4-anti brane moving in the warped 6D bulk space-time. The system of equations of motion for the dynamical codimension2 brane has been derived to describe the cosmological evolution on the probe branes. Some cosmological consequences are investigated.

After decades of research activity, speech recognition technologies have advanced in both the theoretical and practical domains. The technology of speech recognition has evolved from the first attempts at speech analysis with digital computers by James Flanagan’s group at Bell Laboratories in the early 1960s, through to the introduction of dynamic time-warping
