AI and Climate Change: How they're connected, and what we can do about it
The tech industry faces criticism for the significant energy used to power its computing infrastructure. In response, the major tech companies have made data centers more efficient, and worked to ensure they're powered at least in part by renewable energy. These changes are a step in the right direction, but don't come close to tackling the problem. Most large tech companies continue to rely heavily on fossil fuels, and when they do commit to efficiency goals, these are not open to public scrutiny and validation. Researchers Lotfi Belkhir and Ahmed Elmeligi estimate that the tech sector will contribute 3.0–3.6% of global greenhouse emissions by 2020, more than double what the sector produced in 2007 (Belkhir and Elmeligi, 2018).
Mass Automation and Smart Technologies Can Impact Climate Crisis Analytics Insight
With the current levels of technology, already automating most of the human-jobs, it is most likely that people will look out for a new set of jobs by next decade. The disruptive technologies such as IoT, AR/VR, robotics, and artificial intelligence are changing the way we interact, work, and survive. These technologies can even question the role of the human through their highly automated and intelligent systems. In particular, automated innovations have the potential to impact climate change by significantly reducing greenhouse gas emissions and providing précised insights and data to reduce climate change. Currently, agriculture and automobile are the two sectors where humans have been largely replaced by automated and intelligent machines resulting in marking a considerable impression on climate conditions.
AI could fix costly downtime
Unplanned outages are on the rise globally from both equipment failures and damages. Smaller operators do not have the excess capital to conduct the same level of planned outages. As traditional methods of predicting equipment failure can be unreliable in a dynamic operating environment, they can be hesitant to sanction significant shutdown work unless it is absolutely necessary. Thus, they are forced to ride out operational uncertainty and have unfortunately seen unplanned outages increase. Unplanned outages have severe negative cost and production consequences for the operator.
Fully automated ship will trace Mayflower journey
A fully autonomous ship tracing the journey of the Mayflower is being built by a UK-based team, with help from tech firm IBM. The Mayflower Autonomous Ship, or MAS, will launch from Plymouth in the UK in September 2020. Its voyage will mark the 400th anniversary of the pilgrim ship which brought European settlers to America in 1620. IBM is providing artificial intelligence systems for the ship. The vessel will make its own decisions on its course and collision avoidance, and will even make expensive satellite phone calls back to base if it deems it necessary.
PG&E Should Try This ALPS Drone For Fully Automated Power Grid Inspections
ALPS, known for its in-car electronics components has put together a Done system that can autonomously inspect powerline infrastructure. The drone has highly precise and sensitive sensors, including a Lidar, which is a laser-based radar that provides 3D awareness of what's around the drone. As an upgrade, ALPS is working on adapting an RF (radio-frequency) positioning system that has a 30cm (11-inch) precision instead of the normal 16 feet precision of civilian GPS systems. Power companies like PG&E have tested drone inspections since 2016, and it would typically be used for difficult terrain where it is dangerous and time-consuming (expensive) for human personnel to go. An inspection requires a drone pilot and a supporting team.
Leveraging Artificial Intelligence for Materials Design and Production, 2019 Report - ResearchAndMarkets.com
The "Leveraging Artificial Intelligence for Materials Design and Production" report has been added to ResearchAndMarkets.com's offering. Artificial intelligence (AI)- and machine learning (ML)-based technologies are being leveraged for materials research and are replacing experimental and simulation-based research approaches. The need to accelerate materials discovery and the desired accuracy in the properties of materials is driving researchers to seek more granular insights from their experimentations. The development of new materials is a growing field and challenges such as database availability and practical viability of theoretically designed materials are still to be addressed. Multiple research studies from research institutes and companies have developed techniques to use AI-based techniques for the discovery of new molecules that can address existing challenges in the development of new materials and for aiding their mass production.
Data-Driven Deep Learning of Partial Differential Equations in Modal Space
We present a framework for recovering/approximating unknown time-dependent partial differential equation (PDE) using its solution data. Instead of identifying the terms in the underlying PDE, we seek to approximate the evolution operator of the underlying PDE numerically. The evolution operator of the PDE, defined in infinite-dimensional space, maps the solution from a current time to a future time and completely characterizes the solution evolution of the underlying unknown PDE. Our recovery strategy relies on approximation of the evolution operator in a properly defined modal space, i.e., generalized Fourier space, in order to reduce the problem to finite dimensions. The finite dimensional approximation is then accomplished by training a deep neural network structure, which is based on residual network (ResNet), using the given data. Error analysis is provided to illustrate the predictive accuracy of the proposed method. A set of examples of different types of PDEs, including inviscid Burgers' equation that develops discontinuity in its solution, are presented to demonstrate the effectiveness of the proposed method.

V ARIBAD: A V ERY G OOD M ETHOD FOR B AYES-A DAPTIVE D EEP RL VIA M ETA-L EARNING Luisa Zintgraf University of Oxford Kyriacos Shiarlis Latent Logic Maximilian Igl University of Oxford Sebastian Schulze University of Oxford Y arin Gal OA TML Group, University of Oxford Katja Hofmann Microsoft Research Shimon Whiteson University of Oxford Latent Logic A BSTRACT Trading off exploration and exploitation in an unknown environment is key to maximising expected return during learning. A Bayes-optimal policy, which does so optimally, conditions its actions not only on the environment state but on the agent's uncertainty about the environment. Computing a Bayes-optimal policy is however intractable for all but the smallest tasks. In this paper, we introduce variational Bayes-Adaptive Deep RL (variBAD), a way to meta-learn to perform approximate inference in an unknown environment, and incorporate task uncertainty directly during action selection. In a grid-world domain, we illustrate how variBAD performs structured online exploration as a function of task uncertainty. We also evaluate variBAD on MuJoCo domains widely used in meta-RL and show that it achieves higher return during training than existing methods. 1 I NTRODUCTION Reinforcement learning (RL) is typically concerned with finding an optimal policy that maximises expected return for a given Markov decision process (MDP) with an unknown reward and transition function. If these were known, the optimal policy could in theory be computed without interacting with the environment. By contrast, learning in an unknown environment typically requires trading off exploration (learning about the environment) and exploitation (taking promising actions). Balancing this tradeoff is key to maximising expected return during learning . A Bayes-optimal policy, which does so optimally, conditions actions not only on the environment state but on the agent's own uncertainty about the current MDP . In principle, a Bayes-optimal policy can be computed using the framework of Bayes-adaptive Markov decision processes (BAMDPs) (Martin, 1967; Duff & Barto, 2002). The agent maintains a belief, i.e., a posterior distribution, over possible environments. Augmenting the state space of the underlying MDP with this posterior distribution yields a BAMDP, a special case of a belief MDP (Kaelbling et al., 1998).
