... in field data might be addressed in a data-driven framework. In particular, deep learning models trained on synthetic data could be used for inference on the field data. Such an implementation of switching application domains remains challenging. We, therefore, propose the concept of generative dual-band...

...Albert Weaver, III; Grace Callahan; Ashley Hearn; James McCall Key Takeaways Band saw injuries represent 11.5% of all OSHA-reported saw injuries from 1984 through 2017. Potential hazards associated with band saws include unintentional contact with unguarded moving blades or with a blade inside...

... by outliers. Another practical concern is choosing the correct frequency band for the FBE. This can be done by evaluating the model performance on a training set, however we find that the signal quality within a band can diminish over time necessitating a change in the band used. Our challenge is to find...
