This paper presents a framework to define a task with freedom and variability in its goal state. A robot could use this to observe the execution of a task and target a different goal from the observed one; a goal that is still compatible with the task description but would be easier for the robot to execute. We define the model of an environment state and an environment variation, and present experiments on how to interactively create the variation from a single task demonstration and how to use this variation to create an execution plan for bringing any environment into the goal state.

Maintenance can be a complex undertaking, requiring thorough planning and an astute understanding of a facility's risk profile. This is particularly true of high-risk facilities. Maintenance does not occur in a'vacuum' and can result in costly downtimes if it is unexpected or unplanned. Even planned maintenance can lead to lengthy downtimes resulting in huge losses. For example, oil refineries in the US alone lose an estimated $47 billion from 213,000 hours of downtime each year.

Question Answering (QA) systems are increasingly deployed in applications where they support real-world decisions. However, state-of-the-art models rely on deep neural networks, which are difficult to interpret by humans. Inherently interpretable models or post hoc explainability methods can help users to comprehend how a model arrives at its prediction and, if successful, increase their trust in the system. Furthermore, researchers can leverage these insights to develop new methods that are more accurate and less biased. In this paper, we introduce SQuARE v2, the new version of SQuARE, to provide an explainability infrastructure for comparing models based on methods such as saliency maps and graph-based explanations. While saliency maps are useful to inspect the importance of each input token for the model's prediction, graph-based explanations from external Knowledge Graphs enable the users to verify the reasoning behind the model prediction. In addition, we provide multiple adversarial attacks to compare the robustness of QA models. With these explainability methods and adversarial attacks, we aim to ease the research on trustworthy QA models. SQuARE is available on https://square.ukp-lab.de.

Staring closely at the screen, Jordan Wright deftly picks out a barely distinguishable shape with his mouse, bringing to life a stark blue outline from a blur of overexposed features. It's a process similar to the automated tests that teach computers to distinguish humans from machines, by asking someone to identify traffic lights or stop signs in a picture known as a Captcha. Only in Wright's case, the shape turns out to be of a Tupolev Tu-160, a supersonic strategic heavy bomber, parked on a Russian base. The outline -- one of hundreds a day he picks out from satellite images -- is training an algorithm so a US intelligence agency can locate and identify Moscow's firepower in an automated flash. It's become a run-of-the-mill task for the 25-year-old, who describes himself as on the autism spectrum. Starting in the spring, Wright began working at Enabled Intelligence, a Virginia-based startup that works largely for US intelligence and other federal agencies.

Recent progress in state-only imitation learning extends the scope of applicability of imitation learning to real-world settings by relieving the need for observing expert actions. However, existing solutions only learn to extract a state-to-action mapping policy from the data, without considering how the expert plans to the target. This hinders the ability to leverage demonstrations and limits the flexibility of the policy. In this paper, we introduce Decoupled Policy Optimization (DePO), which explicitly decouples the policy as a high-level state planner and an inverse dynamics model. With embedded decoupled policy gradient and generative adversarial training, DePO enables knowledge transfer to different action spaces or state transition dynamics, and can generalize the planner to out-of-demonstration state regions. Our in-depth experimental analysis shows the effectiveness of DePO on learning a generalized target state planner while achieving the best imitation performance. We demonstrate the appealing usage of DePO for transferring across different tasks by pre-training, and the potential for co-training agents with various skills.

New technologies like AI, Data Analytics, and Machine Learning have dominated almost every field in today's ever-evolving high-tech world. With IT companies introducing innovations on a constant basis, the scope for the development of new technologies is limitless. Organizations are already harnessing the potential of AI and Machine Learning to streamline processes internally and analyse information on everything from customer habits to building a knowledge pool to ensure their overall growth. According to the data collected by The International Data Corporation, the AI market can touch up to 7.8$ billion in India by 2025. From a career perspective, through 2023 it is expected that the ML Engineer will be the fastest growing role with open positions for ML engineers at fifty percent of that of data scientists which were less than 10% in 2019.

New technologies can create new opportunities to engage with customers — but is it always worth it for companies to build out a presence on these platforms? When it comes to launching a voice assistant on Amazon Echo or Google Nest, recent research suggests the investment won’t necessarily pay off. The authors analyzed stock price data for nearly 100 companies before and after they released voice assistant features, and they found that while some firms experienced a positive bump in valuation after launching their voice assistant, others experienced no increase or even a notable decrease in market value. Specifically, firms that launched informational features experienced an average 1% increase in valuation, firms that launched object-control features experienced no change in stock price, and firms that launched transactional features actually experienced an average 1.2% decrease in market value. As such, the authors argue that companies should think carefully before investing in a voice assistant to ensure that the value added will be worth the substantial development costs.
