Curriculum-Driven Multi-Agent Learning and the Role of Implicit Communication in Teamwork

arXiv.org Artificial Intelligence

We propose a curriculum-driven learning strategy for solving difficult multi-agent coordination tasks. Our method is inspired by a study of animal communication, which shows that two straightforward design features (mutual reward and decentralization) support a vast spectrum of communication protocols in nature. We highlight the importance of similarly interpreting emergent communication as a spectrum. We introduce a toroidal, continuous-space pursuit-evasion environment and show that naive decentralized learning does not perform well. We then propose a novel curriculum-driven strategy for multi-agent learning. Experiments with pursuit-evasion show that our approach enables decentralized pursuers to learn to coordinate and capture a superior evader, significantly outperforming sophisticated analytical policies. We argue through additional quantitative analysis -- including influence-based measures such as Instantaneous Coordination -- that emergent implicit communication plays a large role in enabling superior levels of coordination.

How AI can enhance customer experience

#artificialintelligence

Many companies seem eager to leverage artificial intelligence and machine learning capabilities, if for no other reason than to be able to let their employees, customers, and business partners know that they're on the leading edge of technology progress. At the same time, a lot of businesses are looking to enhance the experiences of customers and channel partners, in order to increase brand loyalty, boost sales, and gain market share--among other reasons. Some have found a way to combine these goals, using AI-powered tools to improve the way they deliver products, services, and support to their clients and business partners. G&J Pepsi-Cola Bottlers began its foray into AI and machine learning in January 2020, when it partnered with Microsoft to better understand the AI and machine learning components within Microsoft's Azure cloud platform. With guidance from Microsoft's data science team, "we spent time understanding the environment, required skill sets, and began ingesting various data components within Azure ML to provide predicted outcomes," says Brian Balzer, vice president of digital technology and business transformation at G&J Pepsi.


How the use of deep learning algorithms may lead to more accurate HIV diagnoses - Mental Daily

#artificialintelligence

A group of researchers at the University College London and Africa Health Research Institute have constructed an application using artificial intelligence, capable of improving diagnoses of HIV among people with low socioeconomic status. First released in the journal Nature Medicine, researchers used deep learning algorithms, a form of artificial intelligence, to build more robust diagnoses of HIV-based tests for South African populants. "Although deep learning algorithms show increasing promise for disease diagnosis, their use with rapid diagnostic tests performed in the field has not been extensively tested. Here we use deep learning to classify images of rapid human immunodeficiency virus (HIV) tests acquired in rural South Africa," Valérian Turbé and fellow research colleagues wrote in their findings. "Using newly developed image capture protocols with the Samsung SM-P585 tablet, 60 fieldworkers routinely collected images of HIV lateral flow tests."

The Practicalities of Predicting The Future

#artificialintelligence

So, you think I'm kidding about predicting the future? Predicting the future is not only possible, but even simple, if you stack the probabilities on your side by making precise statements about the object and time of the prediction. Example 1: I predict everyone alive today will die. Certainly, there's a non-zero chance I'm wrong, but historically that seems a pretty safe bet. Example 2: Similarly, I can predict that for the next two seconds, you will continue to read this article, or at least finish this sentence. So clearly you can predict many things as a party trick, by picking the right granularity of events and time horizon for the prediction. The question is, where is the line between what's defensible mathematically, and what's actually new information that's useful? If you're too conservative, you end up with tautologies, i.e. statements that are obviously true but add no value or information besides a tired chuckle from the audience. If you're too aggressive, then you'll end up with highly interesting information that simply has no connection to reality, or at best is just a coin toss, and get dismissed as a charlatan. Is there a sweetspot in between? Well, that's what we're going to find out!


On the Cryptographic Hardness of Learning Single Periodic Neurons

arXiv.org Machine Learning

We show a simple reduction which demonstrates the cryptographic hardness of learning a single periodic neuron over isotropic Gaussian distributions in the presence of noise. More precisely, our reduction shows that any polynomial-time algorithm (not necessarily gradient-based) for learning such functions under small noise implies a polynomial-time quantum algorithm for solving worst-case lattice problems, whose hardness form the foundation of lattice-based cryptography. Our core hard family of functions, which are well-approximated by one-layer neural networks, take the general form of a univariate periodic function applied to an affine projection of the data. These functions have appeared in previous seminal works which demonstrate their hardness against gradient-based (Shamir'18), and Statistical Query (SQ) algorithms (Song et al.'17). We show that if (polynomially) small noise is added to the labels, the intractability of learning these functions applies to all polynomial-time algorithms under the aforementioned cryptographic assumptions. Moreover, we demonstrate the necessity of noise in the hardness result by designing a polynomial-time algorithm for learning certain families of such functions under exponentially small adversarial noise. Our proposed algorithm is not a gradient-based or an SQ algorithm, but is rather based on the celebrated Lenstra-Lenstra-Lov\'asz (LLL) lattice basis reduction algorithm. Furthermore, in the absence of noise, this algorithm can be directly applied to solve CLWE detection (Bruna et al.'21) and phase retrieval with an optimal sample complexity of $d+1$ samples. In the former case, this improves upon the quadratic-in-$d$ sample complexity required in (Bruna et al.'21). In the latter case, this improves upon the state-of-the-art AMP-based algorithm, which requires approximately $1.128d$ samples (Barbier et al.'19).


Adversarial Attack on Graph Neural Networks as An Influence Maximization Problem

arXiv.org Artificial Intelligence

Graph neural networks (GNNs) have attracted increasing interests. With broad deployments of GNNs in real-world applications, there is an urgent need for understanding the robustness of GNNs under adversarial attacks, especially in realistic setups. In this work, we study the problem of attacking GNNs in a restricted and realistic setup, by perturbing the features of a small set of nodes, with no access to model parameters and model predictions. Our formal analysis draws a connection between this type of attacks and an influence maximization problem on the graph. This connection not only enhances our understanding on the problem of adversarial attack on GNNs, but also allows us to propose a group of effective and practical attack strategies. Our experiments verify that the proposed attack strategies significantly degrade the performance of three popular GNN models and outperform baseline adversarial attack strategies.

What if we get tech right? 10 experts respond

#artificialintelligence

COVID-19 accelerated the deployment of Fourth Industrial Revolution technologies – reshaping how we work, shop, learn, socialize, even visit the doctor in ways likely to stick around long after the virus is under control. Even when we are able to safely return to "normal" life, continued acceleration of these innovations will be critical to recovery and making progress on our global goals. However, the pandemic also underscored the need for public and private sector governance to address emerging challenges and ensure tech works for everyone. As a recent World Economic Forum report explained, the pandemic "exposed even more clearly the gaps that still exist in digital access." Responsible technology governance is needed to protect against discriminatory algorithms, unethical use of data and job displacement.
