摘要： A system, method and program product for implementing a machine learning platform that processes a data map having feature and operational information. A system is disclosed that includes an interpretable machine learning model that generates a function in response to an inputted data map, wherein the data map includes feature data and operational data over a region of interest, and wherein the function relates a set of predictive variables to one or more response variables; an integration/interpolation system that generates the data map from a set of disparate data sources; and an analysis system that evaluates the function to predict outcomes at unique points in the region of interest.

摘要： A system and computer program product for seismic imaging implements a seismic imaging algorithm utilizing Reverse Time Migration (RTM) and Full Waveform Inversion (FWI) techniques requiring large communication bandwidth and low latency to convert a parallel problem into one solved using massive domain partitioning. Since in RTM and FWI, the forward wave propagation is iteratively calculated on time step increments, there are very high statistical correlation between the intermediate wavefields at the adjacent time steps. This correlation is exploited in compression of the intermediate wavefields so as to achieve much higher compression ratio and avoid the disk IO bottleneck and reduce the overall computing time substantially. Further, during simulation of a reverse wavefield, reverse predictive encoding technique is performed such that snapshots are not recovered in the reverse propagation path due to a prediction chain.
摘要翻译：用于地震成像的系统和计算机程序产品利用需要大的通信带宽和低延迟的反向时间迁移（RTM）和全波形反转（FWI）技术来实现地震成像算法，以将并行问题转换为使用大规模域划分解决的问题。由于在RTM和FWI中，正向波传播是按时间步长递增计算的，相邻时间步长的中间波场之间的统计相关性非常高。这种相关性在中间波场的压缩中得到利用，从而实现了更高的压缩比，并避免了磁盘IO的瓶颈，并大大降低了整体运算时间。此外，在反向波场的仿真期间，执行反向预测编码技术，使得由于预测链而在反向传播路径中不恢复快照。

摘要： A system and computer program product for seismic imaging implements a seismic imaging algorithm utilizing Reverse Time Migration technique requiring large communication bandwidth and low latency to convert a parallel problem into one solved using massive domain partitioning. Since in RTM, both the forward and reverse wave propagation is iteratively calculated on time step increments, the method implements methods that includes partitioning memory between computation and intermediate results to optimize an RTM computation. The methods make maximum use of the memory to either eliminate storing the snapshot wavefield data to disk, or hide all or a significant portion of the disk I/O time. Furthermore, the schemes can provide the flexibility to vary a number of iterations (step size) for each snapshot to be kept in the memory. If any of the given conditions changes during the process, maximum usage of the available memory is ensured.
