A debate between AI experts shows a battle over the technology's future - MIT Technology Review - 0 views

  •  
    "The reason to look at humans is because there are certain things that humans do much better than deep-learning systems. That doesn't mean humans will ultimately be the right model. We want systems that have some properties of computers and some properties that have been borrowed from people. We don't want our AI systems to have bad memory just because people do. But since people are the only model of a system that can develop a deep understanding of something-literally the only model we've got-we need to take that model seriously."

yes, all models are wrong - 0 views

  •  
    "According to Derek & Laura Cabrera, "wicked problems result from the mismatch between how real-world systems work and how we think they work". With systems thinking, there is constant testing and feedback between the real world, in all its complexity, and our mental model of it. This openness to test and look for feedback led Dr. Fisman to change his mind on the airborne spread of the coronavirus."

Digital twin: How a virtual representation of a system boosts effectivity - 0 views

  •  
    "A digital twin is a virtual representation of a real system - a building, the power grid, a city, even a human being - that mimics the characteristics of the system. A digital twin is more than just a computer model, however. It receives data from sensors in the real system to constantly parallel the system's state."

Science relies on computer modelling, but what happens when it goes wrong? -- Science & Technology -- Sott.net - 0 views

  •  
    Much of current science deals with even more complicated systems, and similarly lacks exact solutions. Such models have to be "computational" - describing how a system changes from one instant to the next. But there is no way to determine the exact state at some time in the future other than by "simulating" its evolution in this way. Weather forecasting is a familiar example; until the advent of computers in the 1950s, it was impossible to predict future weather faster than it actually happened.

A machine-learning system that guesses whether text was produced by machine-learning systems / Boing Boing - 0 views

  •  
    "Automatically produced texts use language models derived from statistical analysis of vast corpuses of human-generated text to produce machine-generated texts that can be very hard for a human to distinguish from text produced by another human. These models could help malicious actors in many ways, including generating convincing spam, reviews, and comments -- so it's really important to develop tools that can help us distinguish between human-generated and machine-generated texts."

Together we can thwart the big-tech data grab. Here's how | John Harris | Opinion | The Guardian - 0 views

  •  
    "Blockchain technology has also opened the way to new models whereby endless micropayments can be made in return for particular online services or content; and, if people voluntarily allow elements of their data to be used, rewards can flow the other way. Here perhaps lies the key to a system beyond the current, Google-led model, in which services appear to be free but the letting-go of personal data is the actual price."

Why machine learning struggles with causality | VentureBeat - 0 views

  •  
    "In a paper titled "Towards Causal Representation Learning," researchers at the Max Planck Institute for Intelligent Systems, the Montreal Institute for Learning Algorithms (Mila), and Google Research discuss the challenges arising from the lack of causal representations in machine learning models and provide directions for creating artificial intelligence systems that can learn causal representations."

SoundCloud announces overhaul of royalties model to 'fan-powered' system | Soundcloud | The Guardian - 0 views

  •  
    "SoundCloud announced on Tuesday it would become the first major streaming service to start directing subscribers' fees only to the artists they listen to, a move welcomed by musicians campaigning for fairer pay. Current practice for streaming services including Spotify, Deezer and Apple is to pool royalty payments and dish them out based on which artists have the most global plays. Many artists and unions have criticised this system, saying it disproportionately favours megastars and leaves y little for musicians further down the pecking order."

Harvard Study Proves Apple Slows Down old iPhones to Sell Millions of New Models - Anonymous - 0 views

  •  
    "People have made the anecdotal observation that their Apple products become much slower right before the release of a new model. Now, a Harvard University study has done what any person with Google Trends could do, and pointed out that Google searches for "iPhone slow" spiked multiple times, just before the release of a new iPhone each time."

Algorithmic cruelty: when Gmail adds your harasser to your speed-dial / Boing Boing - 0 views

  •  
    "It's not that Google wants to do this, it's that they didn't anticipate this outcome, and compounded that omission by likewise omitting a way to overrule the algorithm's judgment. As with other examples of algorithmic cruelty, it's not so much this specific example as was it presages for a future in which more and more of our external reality is determined by models derived from machine learning systems whose workings we're not privy to and have no say in.

Ethics committee raises alarm over 'predictive policing' tool | UK news | The Guardian - 0 views

  •  
    "Amid mounting financial pressure, at least a dozen police forces are using or considering predictive analytics, despite warnings from campaigners that use of algorithms and "predictive policing" models risks locking discrimination into the criminal justice system."

the world wide web turns 30 today and its inventor is worried for the future - 0 views

  •  
    "he outlines three sources of dysfunction - 'deliberate, malicious intent, such as state-sponsored hacking and attacks, criminal behaviour, and online harassment'; 'system design' which has created 'perverse incentives where user value is sacrificed, such as ad-based revenue models that commercially reward clickbait'; and the 'viral spread of misinformation'. he also calls attention to the 'unintended negative consequences' of the web, which he said had led to 'the outraged and polarised tone and quality of online discourse'."

Deepfake detectors can be defeated, computer scientists show for the first time | EurekAlert! Science News - 0 views

  •  
    "Researchers showed detectors can be defeated by inserting inputs called adversarial examples into every video frame. The adversarial examples are slightly manipulated inputs which cause artificial intelligence systems such as machine learning models to make a mistake. In addition, the team showed that the attack still works after videos are compressed."

    "These experiments in computational creativity are enabled by the dramatic advances in deep learning over the past decade. Deep learning has several key advantages for creative pursuits. For starters, it's extremely flexible, and it's relatively easy to train deep-learning systems (which we call models) to take on a wide variety of tasks."

Want To Plant One Billion Trees In A Single Year? Try Drones.  | GOOD - 0 views

  •  
    "First, the drones engage in aerial mapping to create detailed three-dimensional terrain models. They then begin "precision planting" by shooting seed pods that have been "pregerminated and covered in a nutritious hydrogel" into the soil. Finally, drones monitor tree growth over the course of a number of "planting audits," designed to track the reforrestation progress. "

How cities can serve as a model for social media platforms to build better community spaces / Boing Boing - 0 views

  •  
    "It's a useful and insightful perspective, particularly for a time when Facebook is cowering under the pressure of conservative conspiracy theorists, while Twitter took the approach and ended up empowering oil companies by throttling climate activists."
