The question isn't whether AI doom is likely. It's whether the expected harm is significant enough to act on. Given the math? The answer is clearly yes. We don't need certainty to justify precaution. We need responsible risk assessment. (7/7)

This same risk framework (expected value of harm) applies to non-catastrophic AI risks too: - Algorithmic bias - Economic displacement - Privacy violations - Misinformation at scale If the product of probability and harm that matters. (6/7) www.ibm.com/think/insigh...

Most AI researchers agree existential risk from AI has LOW probability. But low ≠ zero. And when we're talking about existential outcomes, non-zero probabilities require: - Serious research - Robust safety measures - Contingency planning (5/7) en.wikipedia.org/wiki/Safety_...

We have precedent for this thinking. Before launching the Large Hadron Collider, CERN seriously studied scenarios like micro black holes destroying Earth. Did physicists think it would happen? No. But the potential harm was so large, they HAD to investigate. (4/7) en.wikipedia.org/wiki/Strange...

If potential harm approaches infinity, only a truly negligible probability makes the overall risk acceptable. Low probability ≠ no risk when the stakes are existential. (3/7) en.wikipedia.org/wiki/Risk_as...

What matters is: Probability × Magnitude of Harm = Risk When harm could be civilization-ending, even tiny probabilities demand serious attention. (2/7) en.wikipedia.org/wiki/Risk_ma...

The AI existential risk debate is often framed wrong. People focus on "how likely is this?" But that's not the right question. (1/7) 🧵 en.wikipedia.org/wiki/Existen...

Yet in AI research (which is essentially statistical modeling)we routinely abandon these basic practices. The irony is striking.

Daniel Arteaga @dnlrtg.bsky.social · 27/10/2025
In other scientific fields (natural and social sciences), proper statistical analysis is fundamental. You simply cannot publish without it.

Daniel Arteaga @dnlrtg.bsky.social · 27/10/2025
There's also the added problem that metrics often don't correlate with perception. A 0.1 dB SDR improvement might be meaningless perceptually. But this issue has been discussed more often than the statistical rigor problem.

❌ Claims of "superior performance" based on point estimates alone Example: Paper A reports 15.21 dB, Paper B reports 15.01 dB. Is this difference meaningful or just noise? Do those decimal places have any meaning? Usually impossible to tell from the paper.

Daniel Arteaga @dnlrtg.bsky.social · 27/10/2025
❌ Values without error bars/confidence intervals ❌ Standard deviations sometimes quoted but no uncertainty estimates of means ❌ No significance testing whatsoever ❌ No effect size analysis ❌ No exploratory analysis beyond the mean

We're not even applying methods from first-year undergraduate physics—like reporting results with error bars. The problems I regularly see would make any physics professor cringe.

Coming from a physics background and being familiar with research methodology in fields like neuroscience, I'm struck by the lack of statistical practices in ML/AI papers. Most papers fail at basic statistical analysis that would be expected in other scientific fields. 🧵

We explore 4 DAC-based models: 1️⃣ AR w/ cross-attention 2️⃣ AR w/ classifier guidance 3️⃣ MaskGIT w/ adaptive layer norm 4️⃣ Flow matching The MaskGIT model achieves the best subjective quality (avg. 70 MUSHRA score), beating state of the art comparisons.

Instead of simulating room geometry, we train four different generative model to produce RIRs conditioned on acoustic attributes (T30, T15, EDT, D50, C80, source-receiver distance)

Deep learning based spatial aliasing reduction in beamforming for audio capture

Daniel Arteaga @dnlrtg.bsky.social · 27/05/2025
Spatial aliasing occurs when microphone spacing in an array is too large relative to the wavelength of sound, degrading the accuracy of beamforming. As far as we know, this is the first deep learning paper that addresses directly this problem (other approaches deal with this in an indirect way).

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.
