Classification using K-Nearest Neighbors in kdb+

21 Jun 2018 | , , , , , ,

As part of Kx25, the international kdb+ user conference held May 18th in New York City, a series of seven JuypterQ notebooks were released and are now available on https://code.kx.com/q/ml/. Each notebook demonstrates how to implement a different machine learning technique in kdb+, primarily using embedPy, to solve all kinds of machine learning problems, from feature extraction to fitting and testing a model.

Dimensionality Reduction in kdb+

14 Jun 2018 | , , , , ,

Dimensionality reduction methods have been the focus of much interest within the statistics and machine learning communities for a range of applications. These techniques have a long history as being methods for data pre-processing. Dimensionality reduction is the mapping of data to a lower dimensional space such that uninformative variance in the data is discarded. By doing this we hope to retain only that data that is meaningful to our machine learning problem. In addition, by finding a lower-dimensional representation of a dataset we hope we can improve the efficiency and accuracy of machine learning models.

Case study: Kdb+ Used at NASA Frontier Development Lab in Predictive AI tool

1 May 2018 | ,

The NASA Frontier Development Lab combines the knowledge of planetary scientists and AI researchers to develop tools that benefit all of humanity. However this endeavor can only be achieved with the help and guidance of the FDL’s commercial partners. This case study gives an example of the crucial role of Kx systems technology in the development of a new space weather tool FlareNet.
