We investigate post-softmax calibration for weightedensemble voting in RF signal classification. Neural network confidence scores are often miscalibrated, leading to overconfidentpredictions that degrade ensemble performance. Using per-modeltemperature scaling, we reduce Expected Calibration Error(ECE) from 15.4%…
Ensemble methods for RF signal classification combinepredictions from multiple neural networks to achieve superioraccuracy over individual models. However, modern neural networks often exhibit poor calibration—their confidence scoresdo not reflect actual prediction accuracy [1]. This miscalibration…
Italy has one of the highest numbers of lawyers per capita in the EU, while Belgium—home to the EU institutions—hosts the most lobbyists. Here’s the breakdown: ⚖️ Most Lawyers: Italy 🏛️ Most Lobbyists: Belgium Italy…
Practical RF signal processing pipelines routinely reduce input dimensionality for computational efficiency—downsampling FFTs from 1024 to 256 bins, truncating orinterpolating sequences to 128 samples. While these optimizations improve latency and memory usage, they introduceinformation loss…
To set up OpenOTP, an open-source multi-factor authentication (MFA) solution for various platforms, you will need to install the required software, configure it with the server, and set up the user clients. Here is a…
Photoplethysmography (PPG) is a simple, non-invasive optical technique used to measure volumetric changes in blood circulation in peripheral tissues. It provides a waveform that correlates with blood flow, from which various physiological parameters can be derived. Principle of Operation…
Training and evaluating GANs for brain activity-based image reconstruction is typically a multi-step process involving pre-training on large image datasets, mapping fMRI data to a latent space, and using a combination of quantitative metrics and qualitative human assessment. …
RF signal classification systems frequently encounter sequences shorter than their expected minimum length dueto hardware constraints, burst transmissions, or time-criticalapplications. Traditional ensemble classifiers handle this bystrict abstention—returning control to hierarchical fallbackmethods when N < 32.…
Here’s a breakdown of what Isaac Arthur discussed regarding ultimate weapons. He contrasts two main categories of apocalyptic technology: doomsday devices, which destroy with “brute force,” and ontological weapons, which unmake reality, history, and causality…
