Substitute Missing Values in Altair Knowledge Studio

Datasets often have missing values due to file corruption, failure to record data points, or other causes. Handling missing data values correctly is critical to developing accurate predictive models. Knowledge Studio makes it easy to identify datasets containing missing values and generate new substitute values based on a variety of substitution algorithms. This video walks you through a simple example of how the software’s Substitute Missing Values node works.

Interference and Collocation Interference Demonstration

Radio interference occurs when two or more RF systems affect one another’s smooth operation. This normally occurs when two or more RF systems are operating physically close to one another and they are operating in such a way that one of the transmitters negatively impacts one or more receivers. Through this demonstration video you will learn how to analyze and mitigate collocation interference on a ship and also how to analyze and find solutions for interferences between ground radio stations.

Collocation Interference Analysis Workflow And Exercise

RF co-site interference occurs when two or more co-located RF systems affect one another’s smooth operation. This normally occurs when two or more RF systems are operating physically close to one another and they are operating in such a way that one of the transmitters negatively impacts one or more receivers. This document explains you the workflow and includes an exercise following the steps to solve a co-site interference problem from the creation of the transmitters, receivers and antennas, through the stations and coupling loss matrices, and to the analysis.
