BERT based patent novelty search by training claims to their own description

arXiv.org Machine Learning

In this paper we present a method to concatenate patent claims to their own description. By applying this method, BERT trains suitable descriptions for claims. Such a trained BERT (claim-to-description- BERT) could be able to identify novelty relevant descriptions for patents. In addition, we introduce a new scoring scheme, relevance scoring or novelty scoring, to process the output of BERT in a meaningful way. We tested the method on patent applications by training BERT on the first claims of patents and corresponding descriptions. BERT's output has been processed according to the relevance score and the results compared with the cited X documents in the search reports. The test showed that BERT has scored some of the cited X documents as highly relevant.


Remember What You Want to Forget: Algorithms for Machine Unlearning

arXiv.org Artificial Intelligence

We study the problem of forgetting datapoints from a learnt model. In this case, the learner first receives a dataset $S$ drawn i.i.d. from an unknown distribution, and outputs a predictor $w$ that performs well on unseen samples from that distribution. However, at some point in the future, any training data point $z \in S$ can request to be unlearned, thus prompting the learner to modify its output predictor while still ensuring the same accuracy guarantees. In our work, we initiate a rigorous study of machine unlearning in the population setting, where the goal is to maintain performance on the unseen test loss. We then provide unlearning algorithms for convex loss functions. For the setting of convex losses, we provide an unlearning algorithm that can delete up to $O(n/d^{1/4})$ samples, where $d$ is the problem dimension. In comparison, in general, differentially private learningv(which implies unlearning) only guarantees deletion of $O(n/d^{1/2})$ samples. This shows that unlearning is at least polynomially more efficient than learning privately in terms of dependence on $d$ in the deletion capacity.


Maximize existing QA vision systems with Deep Learning AI - Mariner

#artificialintelligence

The reputation and bottom line of a company can be adversely affected if defective products are released. If a defect is not detected, and the flawed product is not removed early in the production process, the damage can be costly – and the higher the unit value, the higher those costs will be. And worst of all, dissatisfied customers can demand returns. To mitigate these costs, many manufacturers install cameras to monitor their products as they move along their production lines. However, the data obtained may not always be useful – or more appropriately said, the data is useful, but existing machine vision systems may not be able to accurately assess it at full production speeds.


Fostering ethical thinking in computing

#artificialintelligence

Traditional computer scientists and engineers are trained to develop solutions for specific needs, but aren't always trained to consider their broader implications. Each new technology generation, and particularly the rise of artificial intelligence, leads to new kinds of systems, new ways of creating tools, and new forms of data, for which norms, rules, and laws frequently have yet to catch up. The kinds of impact that such innovations have in the world has often not been apparent until many years later. As part of the efforts in Social and Ethical Responsibilities of Computing (SERC) within the MIT Stephen A. Schwarzman College of Computing, a new case studies series examines social, ethical, and policy challenges of present-day efforts in computing with the aim of facilitating the development of responsible "habits of mind and action" for those who create and deploy computing technologies. "Advances in computing have undeniably changed much of how we live and work. Understanding and incorporating broader social context is becoming ever more critical," says Daniel Huttenlocher, dean of the MIT Schwarzman College of Computing.


Smile for the camera: dark side of China's emotion-recognition tech

The Guardian

"Ordinary people here in China aren't happy about this technology but they have no choice. If the police say there have to be cameras in a community, people will just have to live with it. So says Chen Wei at Taigusys, a company specialising in emotion recognition technology, the latest evolution in the broader world of surveillance systems that play a part in nearly every aspect of Chinese society. Emotion-recognition technologies – in which facial expressions of anger, sadness, happiness and boredom, as well as other biometric data are tracked – are supposedly able to infer a person's feelings based on traits such as facial muscle movements, vocal tone, body movements and other biometric signals. It goes beyond facial-recognition technologies, which simply compare faces to determine a match. But similar to facial recognition, it involves the mass collection of sensitive personal data to track, monitor and profile people and uses machine learning to analyse expressions and other clues. The industry is booming in China, where since at least 2012, figures including President Xi Jinping have emphasised the creation of "positive energy" as part of an ideological campaign to encourage certain kinds of expression and limit others. Critics say the technology is based on a pseudo-science of stereotypes, and an increasing number of researchers, lawyers and rights activists believe it has serious implications for human rights, privacy and freedom of expression. With the global industry forecast to be worth nearly $36bn by 2023, growing at nearly 30% a year, rights groups say action needs to be taken now. The main office of Taigusys is tucked behind a few low-rise office buildings in Shenzhen. Visitors are greeted at the doorway by a series of cameras capturing their images on a big screen that displays body temperature, along with age estimates, and other statistics. Chen, a general manager at the company, says the system in the doorway is the company's bestseller at the moment because of high demand during the coronavirus pandemic. Chen hails emotion recognition as a way to predict dangerous behaviour by prisoners, detect potential criminals at police checkpoints, problem pupils in schools and elderly people experiencing dementia in care homes. Taigusys systems are installed in about 300 prisons, detention centres and remand facilities around China, connecting 60,000 cameras. "Violence and suicide are very common in detention centres," says Chen. "Even if police nowadays don't beat prisoners, they often try to wear them down by not allowing them to fall asleep.


AI ethics research conference suspends Google sponsorship

#artificialintelligence

The ACM Conference for Fairness, Accountability, and Transparency (FAccT) has decided to suspend its sponsorship relationship with Google, conference sponsorship co-chair and Boise State University assistant professor Michael Ekstrand confirmed today. The organizers of the AI ethics research conference came to this decision a little over a week after Google fired Ethical AI lead Margaret Mitchell and three months after the firing of Ethical AI co-lead Timnit Gebru. Google has subsequently reorganized about 100 engineers across 10 teams, including placing Ethical AI under the leadership of Google VP Marian Croak. "FAccT is guided by a Strategic Plan, and the conference by-laws charge the Sponsorship Chairs, in collaboration with the Executive Committee, with developing a sponsorship portfolio that aligns with that plan," Ekstrand told VentureBeat in an email. "The Executive Committee made the decision that having Google as a sponsor for the 2021 conference would not be in the best interests of the community and impede the Strategic Plan. We will be revising the sponsorship policy for next year's conference."


How is an AI Ethicist? Here's What Companies Are Looking For.

#artificialintelligence

Artificial intelligence, which was once considered to have the potential to impact lives everywhere is actually affecting thousands of lives every day in reality. AI algorithms are used in almost every sector – criminal justice, recruitment, news media, manufacturing, banking, military, law enforcement, etc. With AI being used in diverse areas, there is a growing worry among researchers that bias in AI can threaten human rights and society, coming in the way of free speech, right to resources and information, to name a few. With such risks, the need for ethical, responsible, and transparent AI is obvious. In 2019, the AI Ethicist role was established as top 5 hires for companies that want to succeed in the digital domain.


Japanese companies ramping up use of artificial intelligence, report says

#artificialintelligence

Fox Business Flash top headlines are here. Check out what's clicking on FoxBusiness.com. TOKYO - Japanese companies are ramping up the use of artificial intelligence and other advanced technology to reduce waste and cut costs in the pandemic, and looking to score some sustainability points along the way. Disposing of Japan's more than 6 million tonnes in food waste costs the world's No.3 economy some 2 trillion yen ($19 billion) a year, government data shows. With the highest food waste per capita in Asia, the Japanese government has enacted a new law to halve such costs from 2000 levels by 2030, pushing companies to find solutions.


Morality, Machines and the Interpretation Problem: A value-based, Wittgensteinian approach to building Moral Agents

arXiv.org Artificial Intelligence

We argue that the attempt to build morality into machines is subject to what we call the Interpretation problem, whereby any rule we give the machine is open to infinite interpretation in ways that we might morally disapprove of, and that the interpretation problem in Artificial Intelligence is an illustration of Wittgenstein's general claim that no rule can contain the criteria for its own application. Using games as an example, we attempt to define the structure of normative spaces and argue that any rule-following within a normative space is guided by values that are external to that space and which cannot themselves be represented as rules. In light of this problem, we analyse the types of mistakes an artificial moral agent could make and we make suggestions about how to build morality into machines by getting them to interpret the rules we give in accordance with these external values, through explicit moral reasoning and the presence of structured values, the adjustment of causal power assigned to the agent and interaction with human agents, such that the machine develops a virtuous character and the impact of the interpretation problem is minimised.


Decision-makers Processing of AI Algorithmic Advice: Automation Bias versus Selective Adherence

arXiv.org Artificial Intelligence

Artificial intelligence algorithms are increasingly adopted as decisional aides by public organisations, with the promise of overcoming biases of human decision-makers. At the same time, the use of algorithms may introduce new biases in the human-algorithm interaction. A key concern emerging from psychology studies regards human overreliance on algorithmic advice even in the face of warning signals and contradictory information from other sources (automation bias). A second concern regards decision-makers inclination to selectively adopt algorithmic advice when it matches their pre-existing beliefs and stereotypes (selective adherence). To date, we lack rigorous empirical evidence about the prevalence of these biases in a public sector context. We assess these via two pre-registered experimental studies (N=1,509), simulating the use of algorithmic advice in decisions pertaining to the employment of school teachers in the Netherlands. In study 1, we test automation bias by exploring participants adherence to a prediction of teachers performance, which contradicts additional evidence, while comparing between two types of predictions: algorithmic v. human-expert. We do not find evidence for automation bias. In study 2, we replicate these findings, and we also test selective adherence by manipulating the teachers ethnic background. We find a propensity for adherence when the advice predicts low performance for a teacher of a negatively stereotyped ethnic minority, with no significant differences between algorithmic and human advice. Overall, our findings of selective, biased adherence belie the promise of neutrality that has propelled algorithm use in the public sector.
