Radiology: Artificial Intelligence
Following the recent award of the Nobel Prize in Physics to Aspect, Clauser, and Zeilinger for their work in quantum mechanics, the journal's October 2022 tweet chat introduced the cutting-edge world of Quantum Machine Learning (QML) and its potential in healthcare. How is QML different from "classical" machine learning? First, to describe the basics of quantum computing, we'll use an analogy from MRI physics with the Bloch sphere (below). In classical computing (a), a binary digit ("bit") has a value of 0 (up) or 1 (down). In quantum computing (b), each quantum bit ("qubit") can hold an infinite number of values between 0 and 1.

Orly's book is an exuberant and insightful account of the bright side of AI and related digital technologies. Her book is filled with fascinating facts and engaging stories. Orly Lobel is the Warren Distinguished Professor of Law; University Professor; and Director, Center for Employment and Labor Policy at the U.C. San Diego School of Law.
Artificial Intelligence and Natural Language Processing and Understanding in Space: A Methodological Framework and Four ESA Case Studies
Gómez-Pérez, José Manuel, García-Silva, Andrés, Leone, Rosemarie, Albani, Mirko, Fontaine, Moritz, Poncet, Charles, Summerer, Leopold, Donati, Alessandro, Roma, Ilaria, Scaglioni, Stefano
The European Space Agency is well known as a powerful force for scientific discovery in numerous areas related to Space. The amount and depth of the knowledge produced throughout the different missions carried out by ESA and their contribution to scientific progress is enormous, involving large collections of documents like scientific publications, feasibility studies, technical reports, and quality management procedures, among many others. Through initiatives like the Open Space Innovation Platform, ESA also acts as a hub for new ideas coming from the wider community across different challenges, contributing to a virtuous circle of scientific discovery and innovation. Handling such wealth of information, of which large part is unstructured text, is a colossal task that goes beyond human capabilities, hence requiring automation. In this paper, we present a methodological framework based on artificial intelligence and natural language processing and understanding to automatically extract information from Space documents, generating value from it, and illustrate such framework through several case studies implemented across different functional areas of ESA, including Mission Design, Quality Assurance, Long-Term Data Preservation, and the Open Space Innovation Platform. In doing so, we demonstrate the value of these technologies in several tasks ranging from effortlessly searching and recommending Space information to automatically determining how innovative an idea can be, answering questions about Space, and generating quizzes regarding quality procedures. Each of these accomplishments represents a step forward in the application of increasingly intelligent AI systems in Space, from structuring and facilitating information access to intelligent systems capable to understand and reason with such information.
D4: a Chinese Dialogue Dataset for Depression-Diagnosis-Oriented Chat
Yao, Binwei, Shi, Chao, Zou, Likai, Dai, Lingfeng, Wu, Mengyue, Chen, Lu, Wang, Zhen, Yu, Kai
In a depression-diagnosis-directed clinical session, doctors initiate a conversation with ample emotional support that guides the patients to expose their symptoms based on clinical diagnosis criteria. Such a dialogue system is distinguished from existing single-purpose human-machine dialog systems, as it combines task-oriented and chit-chats with uniqueness in dialogue topics and procedures. However, due to the social stigma associated with mental illness, the dialogue data related to depression consultation and diagnosis are rarely disclosed. Based on clinical depression diagnostic criteria ICD-11 and DSM-5, we designed a 3-phase procedure to construct D$^4$: a Chinese Dialogue Dataset for Depression-Diagnosis-Oriented Chat, which simulates the dialogue between doctors and patients during the diagnosis of depression, including diagnosis results and symptom summary given by professional psychiatrists for each conversation. Upon the newly-constructed dataset, four tasks mirroring the depression diagnosis process are established: response generation, topic prediction, dialog summary, and severity classification of depressive episode and suicide risk. Multi-scale evaluation results demonstrate that a more empathy-driven and diagnostic-accurate consultation dialogue system trained on our dataset can be achieved compared to rule-based bots.
Deep Learning is Human, Through and Through
Bengio and LeCun see no reason why deep learning systems cannot be made to reason. Said Bengio, "Humans also use some kind of neural nets in their brains, and I believe that there are ways to get to human-like reasoning with deep learning architectures." It was 10 years ago, in 2012, that deep learning made its breakthrough, when an innovative algorithm for classifying images based on multi-layered neural networks suddenly turned out to do spectacularly better than all algorithms before it. That breakthrough has led to deep learning's adoption in domains like speech and image recognition, automatic translation and transcription, and robotics. As deep learning was embedded into ever-more everyday applications, more and more examples of what can go wrong also surfaced: artificial intelligence (AI) systems that discriminate, confirm stereotypes, make inscrutable decisions and require a lot of data and sometimes also a huge amount of energy.
Mapping Process for the Task: Wikidata Statements to Text as Wikipedia Sentences
Ta, Hoang Thang, Gelbukha, Alexander, Sidorov, Grigori
Acknowledged as one of the most successful online cooperative projects in human society, Wikipedia has obtained rapid growth in recent years and desires continuously to expand content and disseminate knowledge values for everyone globally. The shortage of volunteers brings to Wikipedia many issues, including developing content for over 300 languages at the present. Therefore, the benefit that machines can automatically generate content to reduce human efforts on Wikipedia language projects could be considerable. In this paper, we propose our mapping process for the task of converting Wikidata statements to natural language text (WS2T) for Wikipedia projects at the sentence level. The main step is to organize statements, represented as a group of quadruples and triples, and then to map them to corresponding sentences in English Wikipedia. We evaluate the output corpus in various aspects: sentence structure analysis, noise filtering, and relationships between sentence components based on word embedding models. The results are helpful not only for the data-to-text generation task but also for other relevant works in the field.
Will artificial intelligence ever rival true human thinking?
The narrowness of AI will someday be replaced by artificial general intelligence. But will it have the capability to rival human intelligence and creativity? Some of the world's most advanced artificial intelligence (AI) systems, at least the ones the public hear about, are famous for beating human players at chess or poker. Other algorithms are known for their ability to learn how to recognize cats or their inability to recognize people with darker skin. But are current AI systems anything more than toys?
Can Artificial Intelligence Be at Par With or Even Surpass Human Intelligence?
Do you think artificial intelligence can ever be at par with or even surpass human intelligence? This is a question that has been debated by scientists and researchers for years, and there is no clear answer. Some experts believe that artificial intelligence will never be able to replicate or exceed human intelligence, while others feel that it is only a matter of time until AI reaches that level. Is AI capable of surpassing human intelligence, or is that something that is forever reserved for humans? You may have heard of the term'artificial intelligence' but what does it actually mean?
Re3: Generating Longer Stories With Recursive Reprompting and Revision
Yang, Kevin, Tian, Yuandong, Peng, Nanyun, Klein, Dan
We consider the problem of automatically generating longer stories of over two thousand words. Compared to prior work on shorter stories, long-range plot coherence and relevance are more central challenges here. We propose the Recursive Reprompting and Revision framework (Re3) to address these challenges by (a) prompting a general-purpose language model to construct a structured overarching plan, and (b) generating story passages by repeatedly injecting contextual information from both the plan and current story state into a language model prompt. We then revise by (c) reranking different continuations for plot coherence and premise relevance, and finally (d) editing the best continuation for factual consistency. Compared to similar-length stories generated directly from the same base model, human evaluators judged substantially more of Re3's stories as having a coherent overarching plot (by 14% absolute increase), and relevant to the given initial premise (by 20%).

Other algorithms are known for their ability to learn how to recognize cats or their inability to recognize people with darker skin. But are current AI systems anything more than toys? Sure, their ability to play games or identify animals is impressive, but does this help toward creating useful AI systems? To answer this, we need to take a step back and question what the goals of AI are.
