Computational Metacognition

arXiv.org Artificial Intelligence

Computational metacognition represents a cognitive systems perspective on high-order reasoning in integrated artificial systems that seeks to leverage ideas from human metacognition and from metareasoning approaches in artificial intelligence. The key characteristic is to declaratively represent and then monitor traces of cognitive activity in an intelligent system in order to manage the performance of cognition itself. Improvements in cognition then lead to improvements in behavior and thus performance. We illustrate these concepts with an agent implementation in a cognitive architecture called MIDCA and show the value of metacognition in problem-solving. The results illustrate how computational metacognition improves performance by changing cognition through meta-level goal operations and learning.


My Top 10 Predictions: Tech in 2022 - The AI Journal

#artificialintelligence

I started writing this during my winter break but never finished the last few bullets below, and then the Crypto and march crashes seemed imminent this last week, so I am going to put this out there and revisit later this year, on how it turned out. Some of these aren't really predictions but more observations, coupled with my bets on what direction things are heading. I hope these age well, and I'm happy to be wrong about a few of these (and hoping too!). Tell me what you think and what you are betting on.


Adaptive Information Belief Space Planning

arXiv.org Artificial Intelligence

Reasoning about uncertainty is vital in many real-life autonomous systems. However, current state-of-the-art planning algorithms cannot either reason about uncertainty explicitly, or do so with a high computational burden. Here, we focus on making informed decisions efficiently, using reward functions that explicitly deal with uncertainty. We formulate an approximation, namely an abstract observation model, that uses an aggregation scheme to alleviate computational costs. We derive bounds on the expected information-theoretic reward function and, as a consequence, on the value function. We then propose a method to refine aggregation to achieve identical action selection with a fraction of the computational time.


Online Planning in POMDPs with Self-Improving Simulators

arXiv.org Artificial Intelligence

How can we plan efficiently in a large and complex environment when the time budget is limited? However, there are three main limitations of this "twophase" Given the original simulator of the environment, paradigm, where a simulator is learned offline and which may be computationally very demanding, we then used as-is for online simulation and planning. First, no propose to learn online an approximate but much planning is possible until the offline learning phase finishes, faster simulator that improves over time. To plan which can take a long time. Second, the separation of learning reliably and efficiently while the approximate simulator and planning raises a question on what data collection policy is learning, we develop a method that adaptively should be used during training to ensure good online prediction decides which simulator to use for every simulation, during planning. We empirically demonstrate that when based on a statistic that measures the accuracy the training data is collected by a uniform random policy, the of the approximate simulator. This allows us to learned influence predictors can perform poorly during online use the approximate simulator to replace the original planning, due to distribution shift. Third, completely replacing simulator for faster simulations when it is accurate the original simulator with the approximate one after enough under the current context, thus trading training implies a risk of poor planning performance in certain off simulation speed and accuracy. Experimental situations, which is hard to detect in advance.


Path planning in localization uncertaining environment based on Dijkstra method

#artificialintelligence

Path planning obtains the trajectory from one point to another with the robot’s kinematics model and environment understanding. However, as the localization uncertaining through the odometry sensors is inevitably affected, the position of the moving path will deviate further and further compared to the original path, which leads to path drift in GPS denied environments. This paper proposes a novel path planning algorithm based on Dijkstra to address such issues. By combining statistical characteristics of localization error caused by dead-reckoning, the replanned path with minimum cumulative error is generated with uniforming distribution in the searching space. The simulation verifies the effectiveness of the proposed algorithm. Compared with the path generated by traditional planning algorithm, the result of the proposed algorithm has achieved an effective reduction in cumulative errors. Even if the accuracy of the odometry sensor is quite low, our method can still effectively eliminate the cumulative error during the planning process.


Goal Setting in Data Science

#artificialintelligence

In the digital economy, data is the new gold– indeed, there's a new gold rush -- for businesses. To obtain value from gold, the raw material first needs to be processed -- minted into coins or fashioned into jewelry and other products that consumers desire to own and purchase. Similarly, data needs to be processed -- manipulated and analyzed -- to extract real business value. And this is where data science comes in. Data scientists are the prospectors and the tools they use are the innovations that make them more effective.


Top 20 Digital Transformation Pros you NEED To Follow - The AI Journal

#artificialintelligence

Digital Transformation moved at a relatively slow pace for the past ten years, mainly focusing on improving products, employee experience and processes. But then, after COVID – 19 hit, IT decision-makers were forced to prioritize their IT initiatives in order to increase digital investments. According to IDC, over the next four years, worldwide Digital Transformation technology investment is set to reach at least $7.4 trillion and will be the first time that DX will account for the majority of IT spending – predicted to be a huge 53% of budgets. Digital transformation is a set of methodologies and tools which are used by modern companies to optimize their operational activities, such as increasing their reach power, providing differentiated service and increasing performance. However, digital transformation is not just a new department in the firm, but it is definitely a game-changer in technology's role in the corporate environment. That's why it is increasingly being seen as the 4th Industrial Revolution. "Think of digital transformation less as a technology project to be finished than as a state of perpetual agility, always ready to evolve for whatever customers want next, and you'll be pointed down the right path."-


The Rational Selection of Goal Operations and the Integration ofSearch Strategies with Goal-Driven Autonomy

arXiv.org Artificial Intelligence

Intelligent physical systems as embodied cognitive systems must perform high-level reasoning while concurrently managing an underlying control architecture. The link between cognition and control must manage the problem of converting continuous values from the real world to symbolic representations (and back). To generate effective behaviors, reasoning must include a capacity to replan, acquire and update new information, detect and respond to anomalies, and perform various operations on system goals. But, these processes are not independent and need further exploration. This paper examines an agent's choices when multiple goal operations co-occur and interact, and it establishes a method of choosing between them. We demonstrate the benefits and discuss the trade offs involved with this and show positive results in a dynamic marine search task.


Artificial Intelligence Can Help Leaders Drive Global Economy Forward In 2022

#artificialintelligence

Significant hurdles leaders face this year include managing talent, formulating strategies, operational plans, and organizing employee tasks in ways that ensure everyone accesses growth opportunities. These challenges emphasize the importance of good strategy, and are essential for organizational survival. Vijay Pereira, Professor and head of department of people and organizations, at NEOMA Business School in France, believes artificial intelligence (AI) can help leaders undertake these challenges. For example, his recent work concludes that evolutionary computation and data mining can explore large databases or social media to locate potential talented individuals for recruitment purposes. In addition, machine learning helps reanalyze and recognize patterns from data collected from existing decision support systems to help organizations improve their strategic planning processes.


Airlines scramble to rejig schedules amid U.S. 5G rollout concerns

The Japan Times

Major international airlines rushed on Tuesday to rejig or cancel flights to the United States on the eve of a 5G wireless rollout that triggered safety concerns, despite two wireless carriers saying they will delay parts of the deployment. The Federal Aviation Administration has warned that potential 5G interference could affect height readings that play a key role in bad-weather landings on some jets and airlines say the Boeing 777 is among models initially in the spotlight. Despite an announcement by AT&T and Verizon that they would delay turning on some 5G towers near airports, several airlines still canceled flights. Others said more cancellations were likely unless the FAA issued new formal guidance in the wake of the wireless announcements. The world's largest operator of the Boeing 777, Dubai's Emirates, said it would suspend flights to nine U.S. destinations from Jan. 19, the planned date for the deployment of 5G wireless services.
