Recursive Partitioning google
Recursive partitioning is a statistical method for multivariable analysis. Recursive partitioning creates a decision tree that strives to correctly classify members of the population based on several dichotomous independent variables. A variation is ‘Cox linear recursive partitioning’. …

Out-of-core Algorithm google
Out-of-core or external memory algorithms are algorithms that are designed to process data that is too large to fit into a computer’s main memory at one time. Such algorithms must be optimized to efficiently fetch and access data stored in slow bulk memory such as hard drives or tape drives.
A typical example is geographic information systems, especially digital elevation models, where the full data set easily exceeds several gigabytes or even terabytes of data.
This notion naturally extends to a network connecting a data server to a treatment or visualization workstation. Popular mass-of-data based web applications such as google-Map or google-Earth enter this topic.
It also extends to GPU computing – utilizing powerful graphics cards with little memory (compared to CPU memory) and slow CPU-GPU memory transfer (compared to computation bandwidth). …

Operational Modal Analysis (OMA) google
Ambient modal identification, also known as Operational Modal Analysis (OMA), aims at identifying the modal properties of a structure based on vibration data collected when the structure is under its operating conditions, i.e., no initial excitation or known artificial excitation. The modal properties of a structure include primarily the natural frequencies, damping ratios and mode shapes. In an ambient vibration test the subject structure can be under a variety of excitation sources which are not measured but are assumed to be ‘broadband random’. The latter is a notion that one needs to apply when developing an ambient identification method. The specific assumptions vary from one method to another. Regardless of the method used, however, proper modal identification requires that the spectral characteristics of the measured response reflect the properties of the modes rather than those of the excitation. …
