Certified Polyhedral Decompositions of Collision-Free Configuration Space

Dai, Hongkai, Amice, Alexandre, Werner, Peter, Zhang, Annan, Tedrake, Russ

arXiv.org Artificial Intelligence

Understanding the geometry of collision-free configuration space (C-free) in the presence of task-space obstacles is an essential ingredient for collision-free motion planning. While it is possible to check for collisions at a point using standard algorithms, to date no practical method exists for computing C-free regions with rigorous certificates due to the complexity of mapping task-space obstacles through the kinematics. In this work, we present the first to our knowledge rigorous method for approximately decomposing a rational parametrization of C-free into certified polyhedral regions. Our method, called C-IRIS (C-space Iterative Regional Inflation by Semidefinite programming), generates large, convex polytopes in a rational parameterization of the configuration space which are rigorously certified to be collision-free. Such regions have been shown to be useful for both optimization-based and randomized motion planning. Based on convex optimization, our method works in arbitrary dimensions, only makes assumptions about the convexity of the obstacles in the task space, and is fast enough to scale to realistic problems in manipulation. We demonstrate our algorithm's ability to fill a non-trivial amount of collision-free C-space in several 2-DOF examples where the C-space can be visualized, as well as the scalability of our algorithm on a 7-DOF KUKA iiwa, a 6-DOF UR3e and 12-DOF bimanual manipulators. An implementation of our algorithm is open-sourced in Drake. We furthermore provide examples of our algorithm in interactive Python notebooks.


The state of AI in 2022--and a half decade in review

#artificialintelligence

Adoption has more than doubled since 2017, though the proportion of organizations using AI 1 1. In the survey, we defined AI as the ability of a machine to perform cognitive functions that we associate with human minds (for example, natural-language understanding and generation) and to perform physical tasks using cognitive functions (for example, physical robotics, autonomous driving, and manufacturing work). A set of companies seeing the highest financial returns from AI continue to pull ahead of competitors. The results show these leaders making larger investments in AI, engaging in increasingly advanced practices known to enable scale and faster AI development, and showing signs of faring better in the tight market for AI talent. On talent, for the first time, we looked closely at AI hiring and upskilling.


Andrew Ng's Landing AI aims to help manufacturers deploy AI vision systems

#artificialintelligence

Manufacturers are making strides toward Industry 4.0, a movement to tie a company's factory floor technology with the internet of things, business and operation systems, supply chain and aftermarket technology, and scores of equipment. That includes vision inspection systems, which are increasingly going high-tech with the addition of machine learning, artificial intelligence (AI) algorithms that can be trained to catch small blemishes and disfigurements. The information returned from AI inspection systems is part of the massive operating information that can sense, analyze, and respond to changing company conditions. The resulting data is used to streamline operations and improve efficiency, which lead to massive savings – the premise of Industry 4.0. AI in computer vision is no stranger to manufacturing Industry 4.0 or to a number of other markets, such as biomedical and consumer goods.

Top 5 Artificial Intelligence Certifications to Kickstart Your Career in AI

#artificialintelligence

Artificial Intelligence (AI) is a skill one can use for a successful career in any field. It is no longer restricted to the IT industry and professionals with non-technical backgrounds are also entering the field of AI through upskilling. Picture this: the experts' estimation about AI is that by 2030, the contribution of the AI market to the world's economy will be more than USD 15$ trillion. However, there is a huge shortage of skilled (aka certified) professionals in the field of AI. For those who wish to make their career in the field of AI, this is the right time.


Top 4 Artificial Intelligence Engineer certifications in 2021

#artificialintelligence

With the high rise in demand for talent in the field of Artificial Intelligence (AI), the need for professionals who have expertise in this field has also increased immensely. Worldwide, many organizations are on the lookout for individuals who possess a great skillsets in the field of AI. This demand gave rise to the artificial intelligence engineer certification program, which is offered by several online learning institutes. If a person wants to enhance their skill set and also stay ahead in the growing populations then doing a certification program in the field of AI is the best choice. In this article, let's understand the most affordable and industry-recognized top AI certifications that one can do to jump the career ladder.


Is a Machine Learning Certificate Right for You?

#artificialintelligence

Recent years have seen the increasing popularity of certificates as a means for data scientists to build new skills. Companies, such as Google, have even begun offering their own, with promising results. This popularity may be a result of the fact that a machine learning certificate can offer similar amounts of knowledge for less time and costs. There are numerous other benefits as well. There is a lot that can be learned on the job.


RAI's certification process aims to prevent AIs from turning into HALs

Between Microsoft's Tay debacle, the controversies surrounding Northpointe's Compas sentencing software, and Facebook's own algorithms helping spread online hate, AI's more egregious public failings over the past few years have shown off the technology's skeevy underbelly -- and just how much work we have to do before they can reliably and equitably interact with humanity. Of course such incidents have done little to tamp down the hype around and interest in artificial intelligences and machine learning systems, and they certainly haven't slowed the technology's march towards ubiquity. Turns out, one of the primary roadblocks to emerge against AI's continued adoption have been the users themselves. We're no longer the same dial-up rubes we were in the baud rate era. An entire generation has already grown to adulthood without ever knowing the horror of an offline world.


U of T's Schwartz Reisman Institute and AI Global to develop global certification mark for trustworthy AI

#artificialintelligence

The products and services we use in our daily lives have to abide by safety and security standards, from car airbags to construction materials. But no such broad, internationally agreed-upon standards exist for artificial intelligence. And yet, AI tools and technologies are steadily being integrated into all aspects of our lives. AI's potential benefits to humanity, such as improving health-care delivery or tackling climate change, are immense. But potential harms caused by AI tools –from algorithmic bias and labour displacement to risks associated with autonomous vehicles and weapons – risk leading to a lack of trust in AI technologies. To tackle these problems, a new partnership between AI Global, a nonprofit organization focused on advancing responsible and ethical adoption of artificial intelligence, and the Schwartz Reisman Institute for Technology and Society (SRI) at the University of Toronto will create a globally recognized certification mark for the responsible and trusted use of AI systems.


Know the biggest Notable difference between AI vs. Machine Learning

#artificialintelligence

The technological buzz around the world is incomplete without AI and ML. Both of these technologies have revolutionized the world. When we talk about machine learning and artificial intelligence, many people associate it with some high tech work, but these technologies have made their way into our daily lives. Whether we talk about the voice assistant system or the infotainment system of our car, even our coffee machines now perform as per our will, and all this possible because of the development of AI and ML. Although most of us tend to use these words interchangeably, these are different.
