Quantifying and Extrapolating Data Needs in Radio Frequency Machine Learning

no code implementations7 May 2022 William H. Clark IV, Alan J. Michaels

While the model's deployed performance is dependent on numerous variables within the scope of machine learning, beyond that of the training data itself, the effect of the dataset is isolated in this work to better understand the role training data plays in the problem.

Training Data Augmentation for Deep Learning Radio Frequency Systems

no code implementations1 Oct 2020 William H. Clark IV, Steven Hauser, William C. Headley, Alan J. Michaels

Looking into the Radio Frequency Machine Learning (RFML) field of Automatic Modulation Classification (AMC) as an example of a tool used for situational awareness, the use of synthetic, captured, and augmented data are examined and compared to provide insights about the quantity and quality of the available data necessary to achieve desired performance levels.
