Spoken term discovery is a challenging task when a lot of spoken content is generated without annotation. The spoken term discovery task accomplished by pattern matching techniques resolves the challenge by directly capturing the resemblance of the spoken terms at the acoustic feature level. Despite feasibility, the pattern-matching approach generates more false alarms during the discovery task due to fluctuations that arise in natural speech;hence degradation in the performance was observed. In the proposed approach, the challenge that arises due to the variability is addressed in two stages. In the first stage, the RASTA-PLP spectrogram was used as an acoustic feature representation that reduces the variabilities among similar spoken contents. In the second stage, the novel Diagonal pattern Search method unconstrainedly computes the pattern resemblance between the identical spoken terms at the segmental level. The proposed approach was evaluated using the IITKGP-SDUC speech corpus and inferred that a 10.11% improvement in the accuracy was achieved compared to other state-of-the-art systems in the spoken term discovery task.

Reservoir computing (RC) is a promising tool to build data-driven models, which has exhibited excellent performance in dynamical modeling area. Asynchronously deep reservoir computing (ADRC) is an improved version of RC. It generates more diverse dynamics in the reservoir than traditional RCs because of multi-layered structure and asynchronous information process. Reservoir size is a key factor to affect the performance of ADRC. However, the reservoir size of ADRC is very difficult to be determined. To solve this problem, an adaptive PCA (principal component analysis)-like method is proposed. This method promotes the useful reservoir neuron signals while suppresses the useless reservoir neuron signals. It is very similar to the function of PCA in data process. The training way of the adaptive PCA-like ADRC (APCA-ADRC) is derived based on ridge regression technique. The validity of the APCA-ADRC is tested by modeling the SO2 concentration in sulfur recovery unit. Experimental results show it is prominent in building soft sensors with high performance.

Sequence matching in genomics can be approached by quantum computing through Grover's algorithm offering a quadratic speed-up versus the fastest classical algorithms. Previous research using quantum computing focused on long DNA sequences, but application to complex RNA secondary structures with hairpin, bulge, ring, and stem forms has not been possible. This paper developed new formulations for RNA structures using quantum patternrecognition and quantum Hamming distance on Grover's framework by extracting linear regions from the complex forms. To best leverage the quantum speedup, methods are developed to create long sequences by concatenating different linearized parts of the complex RNA structures. The mechanism is simulated on IBM's Qiskit quantum simulator using RNA examples from GenBank and mirBase. Comparisons of the iteration complexity indeed shows the potential for quadratic speedups from quantum computing versus classical. Simulation results also show that search accuracy is very good when using the quantum patternrecognition method.
