Continual World: A Robotic Benchmark For Continual Reinforcement Learning
Wołczyk, Maciej, Zając, Michał, Pascanu, Razvan, Kuciński, Łukasz, Miłoś, Piotr
Continual learning (CL) -- the ability to continuously learn, building on previously acquired knowledge -- is a natural requirement for long-lived autonomous reinforcement learning (RL) agents. While building such agents, one needs to balance opposing desiderata, such as constraints on capacity and compute, the ability to not catastrophically forget, and to exhibit positive transfer on new tasks. Understanding the right trade-off is conceptually and computationally challenging, which we argue has led the community to overly focus on catastrophic forgetting. In response to these issues, we advocate for the need to prioritize forward transfer and propose Continual World, a benchmark consisting of realistic and meaningfully diverse robotic tasks built on top of Meta-World [52] as a testbed. Following an in-depth empirical evaluation of existing CL methods, we pinpoint their limitations and highlight unique algorithmic challenges in the RL setting. Our benchmark aims to provide a meaningful and computationally inexpensive challenge for the community and thus help better understand the performance of existing and future solutions.
How AI Is Infiltrating Higher Education
Students newly accepted by colleges and universities this spring are being deluged by emails and texts in the hope that they will put down their deposits and enroll. If they have questions about deadlines, financial aid, and even where to eat on campus, they can get instant answers. The messages are friendly and informative. Artificial intelligence, or AI, is being used to shoot off these seemingly personal appeals and deliver pre-written information through chatbots and text personas meant to mimic human banter. It can help a university or college by boosting early deposit rates while cutting down on expensive and time-consuming calls to stretched admissions staffs.
How AI Is Accelerating Business Growth and Innovation
Despite the many ominous connotations trumpeted in works of fiction, the adoption and growth of AI can is simply another phase of the technological advance that has marked the development of human society. Yet, because we associate intelligence with living creatures, particularly our own species, the idea of machines that possess that faculty excites some trepidation. AI agents may turn out to be as unpredictable and perverse as any intelligent human. No such worry is evident in Silicon Valley. Sundar Pichai, Google's chief, speaking at the World Economic Forum in Davos, Switzerland, enthused about the technology: "AI is probably the most important thing humanity has ever worked on. I think of it as something more profound than electricity or fire," he said. Google is a major participant in an AI market that is clipping along at a five-year compound annual growth rate (CAGR) of 17.5%. Globally, the industry is projected to swell to $554.3 billion by 2024. Other players of note are IBM, Intuit, Microsoft, OpenText, Palantir, SAS, and Slack.

It's been nearly 4 years since Tensorflow was released, and the library has evolved to its official second version. Tensorflow is Google's library for deep learning and artificial intelligence. Deep Learning has been responsible for some amazing achievements recently, such as: Generating beautiful, photo-realistic images of people and things that never existed (GANs) Beating world champions in the strategy game Go, and complex video games like CS:GO and Dota 2 (Deep Reinforcement Learning) Self-driving cars (Computer Vision) Speech recognition (e.g. Siri) and machine translation (Natural Language Processing) Even creating videos of people doing and saying things they never did (DeepFakes - a potentially nefarious application of deep learning) Tensorflow is the world's most popular library for deep learning, and it's built by Google, whose parent Alphabet recently became the most cash-rich company in the world (just a few days before I wrote this).

'Telling Stories': Imagined tales of artificial intelligence presented by the UW Tech Policy Lab
A young man exiled to a reeducation camp for the "digitally unsafe" learns to keep his face blank, as cameras everywhere read expressions, and signs of anger and resistance are quickly punished. The elderly victim of an attack feels empty after winning justice from a "panel of metal judges" in a future courtroom beyond human biases. An online karate class is taught by artificial intelligence and robots, but over the decades, even as the sport thrives, much of its crucial human element is forgotten. These tales of AI and its effects on future life -- and many more, from points around the world -- are gathered in "Telling Stories: On Culturally Responsive Artificial Intelligence," presented by the University of Washington Tech Policy Lab. The lab is an interdisciplinary collaboration of the UW Paul G. Allen School of Computer Science & Engineering, Information School and School of Law, to "enhance technology policy through research, education and thoughtful leadership."
From Finite to Countable-Armed Bandits
We consider a stochastic bandit problem with countably many arms that belong to a finite set of types, each characterized by a unique mean reward. In addition, there is a fixed distribution over types which sets the proportion of each type in the population of arms. The decision maker is oblivious to the type of any arm and to the aforementioned distribution over types, but perfectly knows the total number of types occurring in the population of arms. We propose a fully adaptive online learning algorithm that achieves O(log n) distribution-dependent expected cumulative regret after any number of plays n, and show that this order of regret is best possible. The analysis of our algorithm relies on newly discovered concentration and convergence properties of optimism-based policies like UCB in finite-armed bandit problems with "zero gap," which may be of independent interest.
Learning First-Order Representations for Planning from Black-Box States: New Results
Rodriguez, Ivan D., Bonet, Blai, Romero, Javier, Geffner, Hector
Recently Bonet and Geffner have shown that first-order representations for planning domains can be learned from the structure of the state space without any prior knowledge about the action schemas or domain predicates. For this, the learning problem is formulated as the search for a simplest first-order domain description D that along with information about instances I_i (number of objects and initial state) determine state space graphs G(P_i) that match the observed state graphs G_i where P_i = (D, I_i). The search is cast and solved approximately by means of a SAT solver that is called over a large family of propositional theories that differ just in the parameters encoding the possible number of action schemas and domain predicates, their arities, and the number of objects. In this work, we push the limits of these learners by moving to an answer set programming (ASP) encoding using the CLINGO system. The new encodings are more transparent and concise, extending the range of possible models while facilitating their exploration. We show that the domains introduced by Bonet and Geffner can be solved more efficiently in the new approach, often optimally, and furthermore, that the approach can be easily extended to handle partial information about the state graphs as well as noise that prevents some states from being distinguished.
Become an AI Product Manager
You'll learn how to evaluate the business value of an AI product. You'll start by building familiarity and fluency with common AI concepts. You'll then learn how to scope and build a data set, train a model, and evaluate its business impact. Finally, you'll learn how to ensure a product is successful by focusing on scalability, potential biases, and compliance. Along the way, you'll review case studies and examples to help you focus on how to define metrics to measure the business value for a proposed product.
A language learning system that pays attention -- more efficiently than ever before
Human language can be inefficient. Just two words, "language" and "inefficient," convey almost the entire meaning of the sentence. When coded into a broader NLP algorithm, the attention mechanism homes in on key words rather than treating every word with equal importance. That yields better results in NLP tasks like detecting positive or negative sentiment or predicting which words should come next in a sentence. The attention mechanism's accuracy often comes at the expense of speed and computing power, however.
