Electromagnetism as a Gauge Theory

PODCAST: This transcript explains how the complex laws of electromagnetism naturally emerge from the principle of local phase symmetry within the Dirac equation. By viewing charged particles as interacting with a universal vector field rather than through telekinesis, the text demonstrates that the electric and… 

Admissibility of Neuroimaging Fishing Expeditions

PODCAST: Notwithstanding Rompilla, forgoing neuroimaging of a defendant evenif the scan might reveal organic brain damage and choosing instead topresent mitigation testimony through lay witnesses has been held to be areasonable trial strategy. As neuroimaging… 

IQ Length Normalization Policies for RF Modulation Classifiers

Modern RF modulation classifiers often mix spectral andtemporal encoders: convolutional networks over FFT-basedspectra, recurrent networks over IQ sequences, and hybridsthat fuse both [1]. Temporal models, in particular, require afixed sequence length L; however, bursts arriving… 

Stacked Meta-Learner Blueprint for RF Modulation Ensembles

Stacking in Automatic Modulation Classification (AMC) Papers Stacking (or stacked generalization) in AMC involves training multiple base learners (e.g., CNNs, LSTMs) on RF signals and using a meta-learner to combine their predictions, often improving robustness…
