The future is intelligent: Harnessing the potential of artificial intelligence in Africa

Curated on Posted on by Stefaan Verhulst

Youssef Travaly and Kevin Muvunyi at Brookings: “…AI in particular presents countless avenues for both the public and private sectors to optimize solutions to the most crucial problems facing the continent today, especially for struggling industries. For example, in health care, AI solutions can help scarce personnel and facilities do more with less by speeding initial processing, triage, diagnosis, and post-care follow up. Furthermore, AI-based pharmacogenomics applications, which focus on the likely response of an individual to therapeutic drugs based on certain genetic markers, can be used to tailor treatments. Considering the genetic diversity found on the African continent, it is highly likely that the application of these technologies in Africa will result in considerable advancement in medical treatment on a global level.

In agriculture, Abdoulaye Baniré Diallo, co-founder and chief scientific officer of the AI startup My Intelligent Machines, is working with advanced algorithms and machine learning methods to leverage genomic precision in livestock production models. With genomic precision, it is possible to build intelligent breeding programs that minimize the ecological footprint, address changing consumer demands, and contribute to the well-being of people and animals alike through the selection of good genetic characteristics at an early stage of the livestock production process. These are just a few examples that illustrate the transformative potential of AI technology in Africa.

However, a number of structural challenges undermine rapid adoption and implementation of AI on the continent. Inadequate basic and digital infrastructure seriously erodes efforts to activate AI-powered solutions as it reduces crucial connectivity. (For more on strategies to improve Africa’s digital infrastructure, see the viewpoint on page 67 of the full report). A lack of flexible and dynamic regulatory systems also frustrates the growth of a digital ecosystem that favors AI technology, especially as tech leaders want to scale across borders. Furthermore, lack of relevant technical skills, particularly for young people, is a growing threat. This skills gap means that those who would have otherwise been at the forefront of building AI are left out, preventing the continent from harnessing the full potential of transformative technologies and industries.

Similarly, the lack of adequate investments in research and development is an important obstacle. Africa must develop innovative financial instruments and public-private partnerships to fund human capital development, including a focus on industrial research and innovation hubs that bridge the gap between higher education institutions and the private sector to ensure the transition of AI products from lab to market….(More)”.

On Digital Disinformation and Democratic Myths

Curated on Posted on by Stefaan Verhulst

 David Karpf at MediaWell: “…How many votes did Cambridge Analytica affect in the 2016 presidential election? How much of a difference did the company actually make?

Cambridge Analytica has become something of a Rorschach test among those who pay attention to digital disinformation and microtargeted propaganda. Some hail the company as a digital Svengali, harnessing the power of big data to reshape the behavior of the American electorate. Others suggest the company was peddling digital snake oil, with outlandish marketing claims that bore little resemblance to their mundane product.

One thing is certain: the company has become a household name, practically synonymous with disinformation and digital propaganda in the aftermath of the 2016 election. It has claimed credit for the surprising success of the Brexit referendum and for the Trump digital strategy. Journalists such as Carole Cadwalladr and Hannes Grasseger and Mikael Krogerus have published longform articles that dive into the “psychographic” breakthroughs that the company claims to have made. Cadwalladr also exposed the links between the company and a network of influential conservative donors and political operatives. Whistleblower Chris Wylie, who worked for a time as the company’s head of research, further detailed how it obtained a massive trove of Facebook data on tens of millions of American citizens, in violation of Facebook’s terms of service. The Cambridge Analytica scandal has been a driving force in the current “techlash,” and has been the topic of congressional hearings, documentaries, mass-market books, and scholarly articles.

The reasons for concern are numerous. The company’s own marketing materials boasted about radical breakthroughs in psychographic targeting—developing psychological profiles of every US voter so that political campaigns could tailor messages to exploit psychological vulnerabilities. Those marketing claims were paired with disturbing revelations about the company violating Facebook’s terms of service to scrape tens of millions of user profiles, which were then compiled into a broader database of US voters. Cambridge Analytica behaved unethically. It either broke a lot of laws or demonstrated that old laws needed updating. When the company shut down, no one seemed to shed a tear.

But what is less clear is just how different Cambridge Analytica’s product actually was from the type of microtargeted digital advertisements that every other US electoral campaign uses. Many of the most prominent researchers warning the public about how Cambridge Analytica uses our digital exhaust to “hack our brains” are marketing professors, more accustomed to studying the impact of advertising in commerce than in elections. The political science research community has been far more skeptical. An investigation from Nature magazine documented that the evidence of Cambridge Analytica’s independent impact on voter behavior is basically nonexistent (Gibney 2018). There is no evidence that psychographic targeting actually works at the scale of the American electorate, and there is also no evidence that Cambridge Analytica in fact deployed psychographic models while working for the Trump campaign. The company clearly broke Facebook’s terms of service in acquiring its massive Facebook dataset. But it is not clear that the massive dataset made much of a difference.

At issue in the Cambridge Analytica case are two baseline assumptions about political persuasion in elections. First, what should be our point of comparison for digital propaganda in elections? Second, how does political persuasion in elections compare to persuasion in commercial arenas and marketing in general?…(More)”.

Three Examples of Data Empowerment

Curated on Posted on by Stefaan Verhulst

Blog by Michael Cañares: “It was a humid December afternoon in Banda Aceh, a bustling city in north Indonesia. Two women members of an education reform advocacy group were busy preparing infographics on how the city government was spending its education budget and its impact on service delivery quality in schools. The room was abuzz with questions and apprehension because the next day, the group would present its analysis on the data that they were able to access for the first time to education department officials. The analyses uncovered inefficiencies, poor school performance, ineffective allocation of resources, among others.

While worried about how the officials would react, almost everyone in the room was cheerful. One advocate told me she found the whole process liberating. She found it exhilarating to use government-published data to ask civil servants why the state of education in some schools was disappointing. “Armed with data, I am no longer afraid to speak my mind,” she said.

This was five years ago, but the memory has stuck with me. It was one of many experiences that inspired me to continue advocating for governments to publish data proactively, and searching for ways to use data to strengthen people’s voice on matters that are important to them.

Globally, there are many examples of how data has enabled people to advocate for their rights, demand better public services or hold governments to account. This blog post shares a few examples, focusing largely on how people are able to access and use data that shape their lives — the first dimension of how we characterize data empowerment….

What is My Data Worth?

Curated on Posted on by Stefaan Verhulst

Ruoxi Jia at Berkeley artificial intelligence research: “People give massive amounts of their personal data to companies every day and these data are used to generate tremendous business values. Some economists and politicians argue that people should be paid for their contributions—but the million-dollar question is: by how much?

This article discusses methods proposed in our recent AISTATS and VLDB papers that attempt to answer this question in the machine learning context. This is joint work with David Dao, Boxin Wang, Frances Ann Hubis, Nezihe Merve Gurel, Nick Hynes, Bo Li, Ce Zhang, Costas J. Spanos, and Dawn Song, as well as a collaborative effort between UC Berkeley, ETH Zurich, and UIUC. More information about the work in our group can be found here.

What are the existing approaches to data valuation?

Various ad-hoc data valuation schemes have been studied in the literature and some of them have been deployed in the existing data marketplaces. From a practitioner’s point of view, they can be grouped into three categories:

  • Query-based pricing attaches values to user-initiated queries. One simple example is to set the price based on the number of queries allowed during a time window. Other more sophisticated examples attempt to adjust the price to some specific criteria, such as arbitrage avoidance.
  • Data attribute-based pricing constructs a price model that takes into account various parameters, such as data age, credibility, potential benefits, etc. The model is trained to match market prices released in public registries.
  • Auction-based pricing designs auctions that dynamically set the price based on bids offered by buyers and sellers.

However, existing data valuation schemes do not take into account the following important desiderata:

  • Task-specificness: The value of data depends on the task it helps to fulfill. For instance, if Alice’s medical record indicates that she has disease A, then her data will be more useful to predict disease A as opposed to other diseases.
  • Fairness: The quality of data from different sources varies dramatically. In the worst-case scenario, adversarial data sources may even degrade model performance via data poisoning attacks. Hence, the data value should reflect the efficacy of data by assigning high values to data which can notably improve the model’s performance.
  • Efficiency: Practical machine learning tasks may involve thousands or billions of data contributors; thus, data valuation techniques should be capable of scaling up.

With the desiderata above, we now discuss a principled notion of data value and computationally efficient algorithms for data valuation….(More)”.

Bridging the Elite-Grassroots Divide Among Anticorruption Activists

Curated on Posted on by Stefaan Verhulst

Abigail Bellows at the Carnegie Endowment for International Peace: “Corruption-fueled political change is occurring at a historic rate—but is not necessarily producing the desired systemic reforms. There are many reasons for this, but one is the dramatic dissipation of public momentum after a transition. In countries like Armenia, the surge in civic participation that generated 2018’s Velvet Revolution largely evaporated after the new government assumed power. That sort of civic demobilization makes it difficult for government reformers, facing stubbornly entrenched interests, to enact a transformative agenda.

The dynamics in Armenia reflect a trend across the anticorruption landscape, which is also echoed in other sectors. As the field has become more professionalized, anticorruption nongovernment organizations (NGOs) have developed the legal and technical expertise to serve as excellent counterparts/watchdogs for government. Yet this strength can also be a hurdle when it comes to building credibility with the everyday people they seek to represent. The result is a disconnect between elite and grassroots actors, which is problematic at multiple levels:

  • Technocratic NGOs lack the “people power” to advance their policy recommendations and are exposed to attack as illegitimate or foreign-sponsored.
  • Grassroots networks struggle to turn protest energy into targeted demands and lasting reform, which can leave citizens frustrated and disillusioned about democracy itself.
  • Government reformers lack the sustained popular mandate to deliver on the ambitious agenda they promised, leaving them politically vulnerable to the next convulsion of public anger at corruption.

Two strategies can help civil society address this challenge. First, organizations can seek to hybridize, with in-house capacities for both policy analysis and mass mobilization. Alternatively, organizations can build formal or informal coalitions between groups operating at the elite and grassroots levels, respectively. Both strategies pose challenges: learning new skills, weaving together distinct organizational cultures and methodologies, and defining demands that are both technically sound and publicly appealing. In many instances, coalition-building will be an easier road given it does not require altering internal organizational and personnel structures. Political windows-of-opportunity on anticorruption may lend urgency to this difficult task and help crystallize what both sides have to gain from increased partnership….(More)“.

The Neuroscience of Trust

Curated on Posted on by Stefaan Verhulst

Paul J. Zak at Harvard Business Review: “…About a decade ago, in an effort to understand how company culture affects performance, I began measuring the brain activity of people while they worked. The neuroscience experiments I have run reveal eight ways that leaders can effectively create and manage a culture of trust. I’ll describe those strategies and explain how some organizations are using them to good effect. But first, let’s look at the science behind the framework.

What’s Happening in the Brain

Back in 2001 I derived a mathematical relationship between trust and economic performance. Though my paper on this research described the social, legal, and economic environments that cause differences in trust, I couldn’t answer the most basic question: Why do two people trust each other in the first place? Experiments around the world have shown that humans are naturally inclined to trust others—but don’t always. I hypothesized that there must be a neurologic signal that indicates when we should trust someone. So I started a long-term research program to see if that was true….

How to Manage for Trust

Through the experiments and the surveys, I identified eight management behaviors that foster trust. These behaviors are measurable and can be managed to improve performance.

Recognize excellence.

The neuroscience shows that recognition has the largest effect on trust when it occurs immediately after a goal has been met, when it comes from peers, and when it’s tangible, unexpected, personal, and public. Public recognition not only uses the power of the crowd to celebrate successes, but also inspires others to aim for excellence. And it gives top performers a forum for sharing best practices, so others can learn from them….(More)”.

Why the Global South should nationalise its data

Curated on Posted on by Stefaan Verhulst

Ulises Ali Mejias at AlJazeera: “The recent coup in Bolivia reminds us that poor countries rich in resources continue to be plagued by the legacy of colonialism. Anything that stands in the way of a foreign corporation’s ability to extract cheap resources must be removed.

Today, apart from minerals and fossil fuels, corporations are after another precious resource: Personal data. As with natural resources, data too has become the target of extractive corporate practices.

As sociologist Nick Couldry and I argue in our book, The Costs of Connection: How Data is Colonizing Human Life and Appropriating It for Capitalism, there is a new form of colonialism emerging in the world: data colonialism. By this, we mean a new resource-grab whereby human life itself has become a direct input into economic production in the form of extracted data.

We acknowledge that this term is controversial, given the extreme physical violence and structures of racism that historical colonialism employed. However, our point is not to say that data colonialism is the same as historical colonialism, but rather to suggest that it shares the same core function: extraction, exploitation, and dispossession.

Like classical colonialism, data colonialism violently reconfigures human relations to economic production. Things like land, water, and other natural resources were valued by native people in the precolonial era, but not in the same way that colonisers (and later, capitalists) came to value them: as private property. Likewise, we are experiencing a situation in which things that were once primarily outside the economic realm – things like our most intimate social interactions with friends and family, or our medical records – have now been commodified and made part of an economic cycle of data extraction that benefits a few corporations.

So what could countries in the Global South do to avoid the dangers of data colonialism?…(More)”.

New Orleans has declared a state of emergency after a cyberattack

Curated on Posted on by Stefaan Verhulst

MIT Technology Review: “The city told its employees to shut down their computers as a precaution this weekend after an attempted cyberattack on Friday.

The news: New Orleans spotted suspicious activity in its networks at around 5 a.m. on Friday, with a spike in the attempted attacks at 8 a.m. It detected phishing attempts and ransomware, Kim LaGrue, the city’s head of IT, later told reporters. Once they were confident the city was under attack, the team shut down its servers and computers. City authorities then filed a declaration of a state of emergency with the Civil District Court, and pulled local, state, and federal authorities into a (still pending) investigation of the incident. The city is still working to recover data from the attack but will be open as usual from this morning, Mayor LaToya Cantrell said on Twitter.

Was it ransomware? The nature of the attack is still something of a mystery. Cantrell confirmed that ransomware had been detected, but the city hasn’t received any demands for ransom money.

The positives: New Orleans was at least fairly well prepared for this attack, thanks to training for this scenario and its ability to operate many of its services without internet access, officials told reporters.

A familiar story: New Orleans is just the latest government to face ransomware attacks, after nearly two dozen cities in Texas were targeted in August, plus Louisiana in November (causing the governor to declare a state of emergency). The phenomenon goes beyond the US, too: in October Johannesburg became the biggest city yet to face a ransomware attack.…(More)”.

Imagery: A better “picture” of the city

Curated on Posted on by Stefaan Verhulst

Daniel Arribas-Bel at Catapult: ‘When trying to understand something as complex as the city, every bit of data helps create a better picture. Researchers, practitioners and policymakers gather as much information as they can to represent every aspect of their city – from noise levels captured by open-source sensors and the study of social isolation using tweets to where the latest hipster coffee shop has opened – exploration and creativity seem to have no limits.

But what about imagery?

You might well ask, what type of images? How do you analyse them? What’s the point anyway?

Let’s start with the why. Images contain visual cues that encode a host of socio-economic information. Imagine a picture of a street with potholes outside a derelict house next to a burnt out car. It may be easy to make some fairly sweeping assumptions about the average income of its resident population. Or the image of a street with a trendy barber-shop next door to a coffee-shop with bare concrete feature walls on one side, and an independent record shop on the other. Again, it may be possible to describe the character of this area.

These are just some of the many kinds of signals embedded in image data. In fact, there is entire literature in geography and sociology that document these associations (see, for example, Cityscapes by Daniel Aaron Silver and Terry Nichols Clark for a sociology approach and The Predictive Postcode by Richard Webber and Roger Burrows for a geography perspective). Imagine if we could figure out ways to condense such information into formal descriptors of cities that help us measure aspects that traditional datasets can’t, or to update them more frequently than standard sources currently allow…(More)”.

Engaging citizens in determining the appropriate conditions and purposes for re-using Health Data

Curated on Posted on by Stefaan Verhulst

Beth Noveck at The GovLab: “…The term, big health data, refers to the ability to gather and analyze vast quantities of online information about health, wellness and lifestyle. It includes not only our medical records but data from apps that track what we buy, how often we exercise and how well we sleep, among many other things. It provides an ocean of information about how healthy or ill we are, and unsurprisingly, doctors, medical researchers, healthcare organizations, insurance companies and governments are keen to get access to it. Should they be allowed to?

It’s a huge question, and AARP is partnering with GovLab to learn what older Americans think about it. AARP is a non-profit organization — the largest in the nation and the world — dedicated to empowering Americans to choose how they live as they age. In 2018 it had more than 38 million members. It is a key voice in policymaking in the United States, because it represents the views of people aged over 50 in this country.

From today, AARP and the GovLab are using the Internet to capture what AARP members feel are the most urgent issues confronting them to try to discover what worries people most: the use of big health data or the failure to use it.

The answers are not simple. On the one hand, increasing the use and sharing of data could enable doctors to make better diagnoses and interventions to prevent disease and make us healthier. It could lead medical researchers to find cures faster, while the creation of health data businesses could strengthen the economy.

On the other hand, the collection, sharing, and use of big health data could reveal sensitive personal information over which we have little control. This data could be sold without our consent, and be used by entities for surveillance or discrimination, rather than to promote well-being….(More)”.
