Transfer learning for deep neural network-based partial differential equations solving
Advances in Aerodynamics, 2021 Deep neural networks (DNNs) have recently shown great potential in solving partial differential equations (PDEs). The success of neural network-based surrogate models is attributed to their ability to learn a rich set of solution-related features ...

The VEGA moderately parallel MIMD, moderately parallel SIMD, architecture for high performance array signal processing [PDF]
, 1998 In array radar signal processing applications, the processing demands range from tens of GFLOPS to several TFLOPS. To address this, as well as the, size and power dissipation issues, a special purpose “array signal processing” architecture is proposed ...

Developing a new mesh quality evaluation method based on convolutional neural network
Engineering Applications of Computational Fluid Mechanics, 2020 One of the difficult requirements imposed on high-quality CFD mesh generation has been the ability to evaluate the mesh quality efficiently. Due to the lack of a general and effective evaluating criterion, the current mesh quality evaluation task mainly ...

A fixed-point parallel convolver without precision loss for the real-time processing of long numerical sequences [PDF]
, 1995 A parallel architecture, able to convolve in real-time long numerical sequences with long filter functions is shown. Real-time is intended as a processing made at the same frequency of the data input access with a minimum delay of the output production ...

A Large-Gap Clone Detection Approach Using Sequence Alignment via Dynamic Parameter Optimization
IEEE Access, 2019 Large-gap clones, a kind of clones that reuses code with many edits, are very common in software development practice and widespread in software systems. The detection of such clones is very crucial.

Skew in parallel query processing [PDF]
Proceedings of the 33rd ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems, 2014 We study the problem of computing a conjunctive query q in parallel, using p of servers, on a large database. We consider algorithms with one round of communication, and study the complexity of the communication. We are especially interested in the case where the data is skewed, which is a major challenge for scalable parallel query processing.
