AI-Powered World Health Chatbot Is Flubbing Some Answers

Curated on Posted on by Stefaan Verhulst

Article by Jessica Nix: “The World Health Organization is wading into the world of AI to provide basic health information through a human-like avatar. But while the bot responds sympathetically to users’ facial expressions, it doesn’t always know what it’s talking about.

SARAH, short for Smart AI Resource Assistant for Health, is a virtual health worker that’s available to talk 24/7 in eight different languages to explain topics like mental health, tobacco use and healthy eating. It’s part of the WHO’s campaign to find technology that can both educate people and fill staffing gaps with the world facing a health-care worker shortage.

WHO warns on its website that this early prototype, introduced on April 2, provides responses that “may not always be accurate.” Some of SARAH’s AI training is years behind the latest data. And the bot occasionally provides bizarre answers, known as hallucinations in AI models, that can spread misinformation about public health.The WHO’s artificial intelligence tool provides public health information via a lifelike avatar.Source: Bloomberg

SARAH doesn’t have a diagnostic feature like WebMD or Google. In fact, the bot is programmed to not talk about anything outside of the WHO’s purview, including questions on specific drugs. So SARAH often sends people to a WHO website or says that users should “consult with your health-care provider.”

“It lacks depth,” Ramin Javan, a radiologist and researcher at George Washington University, said. “But I think it’s because they just don’t want to overstep their boundaries and this is just the first step.”..(More)”

What can improve democracy?

Curated on Posted on by Stefaan Verhulst

Report by the Pew Research Center: “…surveys have long found that people in many countries are dissatisfied with their democracy and want major changes to their political systems – and this year is no exception. But high and growing rates of discontent certainly raise the question: What do people think could fix things?

A graphic showing that People in most countries surveyed suggest changes to politicians will improve democracy

We set out to answer this by asking more than 30,000 respondents in 24 countries an open-ended question: “What do you think would help improve the way democracy in your country is working?” While the second- and third-most mentioned priorities vary greatly, across most countries surveyed, there is one clear top answer: Democracy can be improved with better or different politicians.

People want politicians who are more responsive to their needs and who are more competent and honest, among other factors. People also focus on questions of descriptive representation – the importance of having politicians with certain characteristics such as a specific race, religion or gender.

Respondents also think citizens can improve their own democracy. Across most of the 24 countries surveyed, issues of public participation and of different behavior from the people themselves are a top-five priority.

Other topics that come up regularly include:

  • Economic reform, especially reforms that will enhance job creation.
  • Government reform, including implementing term limits, adjusting the balance of power between institutions and other factors.

We explore these topics and the others we coded in the following chapters:

  • Politicians, changing leadership and political parties (Chapter 1)
  • Government reform, special interests and the media (Chapter 2)
  • Economic and policy changes (Chapter 3)
  • Citizen behavior and individual rights and equality (Chapter 4)
  • Electoral reform and direct democracy (Chapter 5)
  • Rule of law, safety and the judicial system (Chapter 6)…(More)”.

Using Artificial Intelligence to Map the Earth’s Forests

Curated on Posted on by Stefaan Verhulst

Article from Meta and World Resources Institute: “Forests harbor most of Earth’s terrestrial biodiversity and play a critical role in the uptake of carbon dioxide from the atmosphere. Ecosystem services provided by forests underpin an essential defense against the climate and biodiversity crises. However, critical gaps remain in the scientific understanding of the structure and extent of global forests. Because the vast majority of existing data on global forests is derived from low to medium resolution satellite imagery (10 or 30 meters), there is a gap in the scientific understanding of dynamic and more dispersed forest systems such as agroforestry, drylands forests, and alpine forests, which together constitute more than a third of the world’s forests. 

Today, Meta and World Resources Institute are launching a global map of tree canopy height at a 1-meter resolution, allowing the detection of single trees at a global scale. In an effort to advance open source forest monitoring, all canopy height data and artificial intelligence models are free and publicly available…(More)”.

Social Choice for AI Alignment: Dealing with Diverse Human Feedback

Curated on Posted on by Stefaan Verhulst

Paper by Vincent Conitzer, et al: “Foundation models such as GPT-4 are fine-tuned to avoid unsafe or otherwise problematic behavior, so that, for example, they refuse to comply with requests for help with committing crimes or with producing racist text. One approach to fine-tuning, called reinforcement learning from human feedback, learns from humans’ expressed preferences over multiple outputs. Another approach is constitutional AI, in which the input from humans is a list of high-level principles. But how do we deal with potentially diverging input from humans? How can we aggregate the input into consistent data about ”collective” preferences or otherwise use it to make collective choices about model behavior? In this paper, we argue that the field of social choice is well positioned to address these questions…(More)”.

We Need To Rewild The Internet

Curated on Posted on by Stefaan Verhulst

Article by Maria Farrell and Robin Berjon: “In the late 18th century, officials in Prussia and Saxony began to rearrange their complex, diverse forests into straight rows of single-species trees. Forests had been sources of food, grazing, shelter, medicine, bedding and more for the people who lived in and around them, but to the early modern state, they were simply a source of timber.

So-called “scientific forestry” was that century’s growth hacking. It made timber yields easier to count, predict and harvest, and meant owners no longer relied on skilled local foresters to manage forests. They were replaced with lower-skilled laborers following basic algorithmic instructions to keep the monocrop tidy, the understory bare.

Information and decision-making power now flowed straight to the top. Decades later when the first crop was felled, vast fortunes were made, tree by standardized tree. The clear-felled forests were replanted, with hopes of extending the boom. Readers of the American political anthropologist of anarchy and order, James C. Scott, know what happened next.

It was a disaster so bad that a new word, Waldsterben, or “forest death,” was minted to describe the result. All the same species and age, the trees were flattened in storms, ravaged by insects and disease — even the survivors were spindly and weak. Forests were now so tidy and bare, they were all but dead. The first magnificent bounty had not been the beginning of endless riches, but a one-off harvesting of millennia of soil wealth built up by biodiversity and symbiosis. Complexity was the goose that laid golden eggs, and she had been slaughtered…(More)”.

On the Manipulation of Information by Governments

Curated on Posted on by Stefaan Verhulst

Paper by Ariel Karlinsky and Moses Shayo: “Governmental information manipulation has been hard to measure and study systematically. We hand-collect data from official and unofficial sources in 134 countries to estimate misreporting of Covid mortality during 2020-21. We find that between 45%–55% of governments misreported the number of deaths. The lion’s share of misreporting cannot be attributed to a country’s capacity to accurately diagnose and report deaths. Contrary to some theoretical expectations, there is little evidence of governments exaggerating the severity of the pandemic. Misreporting is higher where governments face few social and institutional constraints, in countries holding elections, and in countries with a communist legacy…(More)”

The economic research policymakers actually need

Curated on Posted on by Stefaan Verhulst

Blog by Jed Kolko: “…The structure of academia just isn’t set up to produce the kind of research many policymakers need. Instead, top academic journal editors and tenure committees reward research that pushes the boundaries of the discipline and makes new theoretical or empirical contributions. And most academic papers presume familiarity with the relevant academic literature, making it difficult for anyone outside of academia to make the best possible use of them.

The most useful research often came instead from regional Federal Reserve banks, non-partisan think-tanks, the corporate sector, and from academics who had the support, freedom, or job security to prioritize policy relevance. It generally fell into three categories:

  1. New measures of the economy
  2. Broad literature reviews
  3. Analyses that directly quantify or simulate policy decisions.

If you’re an economic researcher and you want to do work that is actually helpful for policymakers — and increases economists’ influence in government — aim for one of those three buckets.

The pandemic and its aftermath brought an urgent need for data at higher frequency, with greater geographic and sectoral detail, and about ways the economy suddenly changed. Some of the most useful research contributions during that period were new data and measures of the economy: they were valuable as ingredients rather than as recipes or finished meals. Here are some examples:

Technological Progress and Rent Seeking

Curated on Posted on by Stefaan Verhulst

Paper by Vincent Glode & Guillermo Ordoñez: “We model firms’ allocation of resources across surplus-creating (i.e., productive) and surplus-appropriating (i.e., rent-seeking) activities. Our model predicts that industry-wide technological advancements, such as recent progress in data collection and processing, induce a disproportionate and socially inefficient reallocation of resources toward surplus-appropriating activities. As technology improves, firms rely more on appropriation to obtain their profits, endogenously reducing the impact of technological progress on economic progress and inflating the price of the resources used for both types of activities. We apply our theoretical insights to shed light on the rise of high-frequency trading…(More)”,

Democracy and Artificial Intelligence: old problems, new solutions?

Curated on Posted on by Stefaan Verhulst

Discussion between Nardine Alnemr and Rob Weymouth: “…I see three big perspectives relevant to AI and democracy. You have the most conservative, mirroring the 80s and the 90s, still talking about the digital public sphere as if it’s distant from our lives. As if it’s something novel and inaccessible, which is not quite accurate anymore.

Then there’s the more optimistic and cautionary side of the spectrum. People who are excited about the technologies, but they’re not quite sure. They’re intrigued to see the potential and I think they’re optimistic because they overlook how these technologies connect to a broader context. How a lot of these technologies are driven by surveying and surveillance of the data and the communication that we produce. Exploitation of workers who do the filtering and cleaning work. The companies that profit out of this and make engineered election campaigns. So they’re cautious because of that, but still optimistic, because at the same time, they try to isolate it from that bigger context.

And finally, the most radical is something like Cesar Hidalgo’s proposal of augmented democracy…(More)”.
