Show HN: RealtimeVAD – trading false positives for 110ms earlier end-of-speech

Hey guys. I recently watched the latency reports for my local voice assistant, which show a waveform plus silero probability for voice activity. I noticed silero lags visibly on the speech off signal. There had to be a method to get this signal closer to what I felt is optimal. My idea was to use a 10 ms energy detector with a threshold that adapts to environment or room noise. Which worked amazingly well. It created more false positives but in my speculative generation pipeline that would not matter. If it's wrong and the user continues speaking I can abort the pipeline fast. I benchmarked my

False faced: can a simple classifier tell when a model is manipulating its activations to evade probes?

This experiment was a submission to my Statistics & Probability course Bayesian classifiers project. TL;DR: We test whether simple classifiers can tell when a model is hiding concepts in its activations to evade probes. We find that, for Bayesian classifiers, the probabilities are enough to separate most evading rows from the rest on concepts seen in training, but the correlation aspect through the pairs of dimensions that the Dependent version adds over the Naive approach does not measurably help. None of the classifiers work on a new concept, because they learn the trigger word that elicits

$54 billion in false promises about Alaska LNG

The claims by President Donald Trump and Alaska Republicans that South Korea has agreed to pay more than $54 billion to build the Alaska LNG project were nothing but a pre-election effort to try to boost the reelection campaign of Sen. Dan Sullivan. The news emerging from South Korea continues to show that what Trump, Sullivan, Gov. Mike Dunleavy and Rep. Nick Begich the Third said about the gasline in the Oval Office on September 30 was a con job.
