☮ ♥ ♬ 🧑💻<p>Probabilistic weather forecasting with machine learning: “Weather forecasts are fundamentally uncertain, so predicting the range of probable weather scenarios is crucial for important decisions, from warning the public about hazardous weather to planning renewable energy use. </p><p>Traditionally, <a href="https://ioc.exchange/tags/WeatherForecasts" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>WeatherForecasts</span></a> have been based on numerical weather prediction (NWP), which relies on physics-based simulations of the atmosphere.

With few exceptions, they stay in their own lanes and do not mix outside their field/subfield. Their writings are stand-alone, rarely intended to connect back to the greater human knowledge base. They'll tell you exactly what "wet" or "sound" is, based entirely on their tiny-desk world-view.</p><p>The other way would be a general model of vibration, perhaps based on quantitative info rather than qualitative. It would incorporate all modes of vibratory phenomena, regardless of mediums, velocities, or other characteristics that were fleshed out by some subfield as critical for their particular context & definitions.</p><p>Frequency (Hz) actually would be a good quantitative baseline for this, if it hadn't been exorcised from <a href="https://c.im/tags/quantum" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>quantum</span></a> mechanics.</p><p>The "old QM", as espoused by the founders and historic supporters for the split in Physics, used a semi-classical approach that was later abandoned. Later, Pi was added to E = hf as convenience for some aspects, but frequency generally falls away when you work with quantum states ala Schrödinger. <a href="https://c.im/tags/Time" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Time</span></a> is just an input to QM, and is the <a href="https://c.im/tags/Newtonian" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Newtonian</span></a>, absolute kind.

Chuck Darwin<p>Which brings us to political economy – of course. </p><p>Because this turn to defense contracting that the large tech companies have been making is a key part of their revenue model. </p><p>Work by Tech Inquiry recently revealed that <br>the five largest US military contracts to major tech firms between 2019 and 2022 <br>have contract ceilings of $53 billion. </p><p>And those are the ones we know of. </p><p>Due to the combination of military classification and corporate secrecy <br>– transparency <br>– let alone accountability<br> – is very hard to come by.</p><p>The use of <a href="https://c.im/tags/probabilistic" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>probabilistic</span></a> techniques to determine who is worthy of death <br>– wherever they’re used <br>– is, to me, the most chilling example of the serious dangers of the current centralized AI industry ecosystem, <br>and of the very material risks of believing the bombastic claims of intelligence and accuracy that are used to market these inaccurate systems. </p><p>And to justify carnage under the banner of computational sophistication. </p><p>As UN Secretary General Antonio Gutiérrez put it, <br>“machines that have the power and the discretion to take human lives are politically unacceptable, <br>are morally repugnant, <br>and should be banned by international law.” </p><p>It’s because of this that I join the<br> German Forum of Computer Scientists for Peace and Social Responsibility<br> in demanding that <br>“practices of targeted killing with supporting systems be outlawed as war crimes.” </p><p>Particularly given the very real possibility of a more authoritarian government in the US, where these companies are homed. </p><p>A place where the right wing in the country has already broadcast plans to <br>bring the two major tech regulators in the US<br>–the Federal Trade Commission and the Federal Communications Commission<br>–under direct presidential control in the future. </p><p>Where four of the top five social media platforms are housed, alongside cloud giants that currently control 70% of the global cloud market. </p><p>And where a federal abortion ban is on the right wing agenda, <br>accompanied by ongoing campaigns of book banning and censorship of LGBTQ resources and expression <br>already shaping legislation at the state level.</p><p>(6/8)</p>
