Lost in Translation: Reimagining the Machine Learning Life Cycle in Education
Liu, Lydia T., Wang, Serena, Britton, Tolani, Abebe, Rediet
Machine learning (ML) techniques are increasingly prevalent in education, from their use in predicting student dropout, to assisting in university admissions, and facilitating the rise of MOOCs. Given the rapid growth of these novel uses, there is a pressing need to investigate how ML techniques support long-standing education principles and goals. In this work, we shed light on this complex landscape drawing on qualitative insights from interviews with education experts. These interviews comprise in-depth evaluations of ML for education (ML4Ed) papers published in preeminent applied ML conferences over the past decade. Our central research goal is to critically examine how the stated or implied education and societal objectives of these papers are aligned with the ML problems they tackle. That is, to what extent does the technical problem formulation, objectives, approach, and interpretation of results align with the education problem at hand. We find that a cross-disciplinary gap exists and is particularly salient in two parts of the ML life cycle: the formulation of an ML problem from education goals and the translation of predictions to interventions. We use these insights to propose an extended ML life cycle, which may also apply to the use of ML in other domains. Our work joins a growing number of meta-analytical studies across education and ML research, as well as critical analyses of the societal impact of ML. Specifically, it fills a gap between the prevailing technical understanding of machine learning and the perspective of education researchers working with students and in policy.
Participant Perceptions of a Robotic Coach Conducting Positive Psychology Exercises: A Systematic Analysis
Axelsson, Minja, Churamani, Nikhil, Caldir, Atahan, Gunes, Hatice
While mindfulness provides a meditation-based tool for alleviating anxiety and depression levels [68], PP is a branch of psychology that aims to enhance well-being by focusing particularly on the positive experiences of people and positive individual traits [33], [84]. Such positive reflection has been shown to increase feelings of positive affect and future expectancy in individuals [76]. With the recent COVID-19 pandemic, the general population has been severely impacted, resulting in negative mental health outcomes [87]. People have found it particularly difficult to seek mental health advice and treatment due to social distancing regulations imposed [52]. As a result, digital forms of healthcare have been applied to assist individuals in need [66]. These include telehealth services via video calls, online therapies, and self-help resources through mobile and web apps.
reStructured Pre-training
In this work, we try to decipher the internal connection of NLP technology development in the past decades, searching for essence, which rewards us with a (potential) new learning paradigm for NLP tasks, dubbed as reStructured Pre-training (RST). In such a paradigm, the role of data will be re-emphasized, and model pre-training and fine-tuning of downstream tasks are viewed as a process of data storing and accessing. Based on that, we operationalize the simple principle that a good storage mechanism should not only have the ability to cache a large amount of data but also consider the ease of access. We achieve this by pre-training models over restructured data that consist of a variety of valuable information instead of raw data after overcoming several engineering challenges. Experimentally, RST models not only surpass strong competitors (e.g., T0) on 52/55 popular datasets from a variety of NLP tasks (e.g., classification, information extraction, fact retrieval, text generation, etc.) without fine-tuning on downstream tasks, but also achieve superior performance in National College Entrance Examination - English (Gaokao-English), the most authoritative examination in China, which millions of students will attend every year. Specifically, the proposed system Qin () achieves 40 points higher than the average scores made by students and 15 points higher than GPT3 with 1/16 parameters. In particular, Qin gets a high score of 138.5 (the full mark is 150) in the 2018 English exam (national paper III). We have released the Gaokao Benchmark with an online submission platform that contains ten annotated English papers from 2018-2021 so far (and will be expanded annually), which allows more AI models to attend Gaokao, establishing a relatively fair test bed for human and AI competition and helping us better understand where we are. We test our model in the 2022 College Entrance Examination English that happened a few days ago (2022.06.08), and it gets a total score of 134 (v.s.
Artificial Intelligence Has a Strange New Muse: Our Sense of Smell
Today's artificial intelligence systems, including the artificial neural networks broadly inspired by the neurons and connections of the nervous system, perform wonderfully at tasks with known constraints. They also tend to require a lot of computational power and vast quantities of training data. That all serves to make them great at playing chess or Go, at detecting if there's a car in an image, at differentiating between depictions of cats and dogs. "But they are rather pathetic at composing music or writing short stories," said Konrad Kording, a computational neuroscientist at the University of Pennsylvania. "They have great trouble reasoning meaningfully in the world."

Artificial Intelligence is quickly becoming one of the key factors in advancements in the healthcare industry. Ahead of the RE•WORK – AI in Healthcare Summit Boston, we asked Nathan Wang – Deep Learning/Medical Imaging Researcher at Johns Hopkins University his thoughts on the topic. Here's what he had to say: What do you think is the most important advancement for AI in healthcare? In recent years, the field has made great strides in model interpretability. As a researcher, being able to intuitively grasp the "reasoning" behind our AI helps us build more robust and accurate models.
Neural-Symbolic Models for Logical Queries on Knowledge Graphs
Zhu, Zhaocheng, Galkin, Mikhail, Zhang, Zuobai, Tang, Jian
Answering complex first-order logic (FOL) queries on knowledge graphs is a fundamental task for multi-hop reasoning. Traditional symbolic methods traverse a complete knowledge graph to extract the answers, which provides good interpretation for each step. Recent neural methods learn geometric embeddings for complex queries. These methods can generalize to incomplete knowledge graphs, but their reasoning process is hard to interpret. In this paper, we propose Graph Neural Network Query Executor (GNN-QE), a neural-symbolic model that enjoys the advantages of both worlds. GNN-QE decomposes a complex FOL query into relation projections and logical operations over fuzzy sets, which provides interpretability for intermediate variables. To reason about the missing links, GNN-QE adapts a graph neural network from knowledge graph completion to execute the relation projections, and models the logical operations with product fuzzy logic. Experiments on 3 datasets show that GNN-QE significantly improves over previous state-of-the-art models in answering FOL queries. Meanwhile, GNN-QE can predict the number of answers without explicit supervision, and provide visualizations for intermediate variables.
A fascination with breathing life into AI creations can mislead us
Earlier this year, an interesting interview took place between two engineers working at Google and a'chatbot' called LaMDA, short for Language Model for Dialogue Applications. Google engineer Blake Lemoine and his colleague had a strong suspicion that their creation LaMDA was actually sentient, that it could be perceptive and have feelings, and they wanted to check it out through their own version of the Turing Test. When asked whether LaMDA thought it was a person, it replied: "Absolutely. I want everyone to understand that I am, in fact, a person." LaMDA was then asked that if this was so then what was the kind of consciousness or sentience it had, to which it replied: "The nature of my consciousness/sentience is that I am aware of my existence, I desire to learn more about the world, and I feel happy or sad at times."
Controversy erupts over prize awarded to AI-generated art
The winning artwork was created using the AI tool Midjourney – which turns lines of text into astonishingly realistic graphics. The award came with a $300 cash prize. AI tools to generate images have been around for years with companies such as Google and OpenAI being notable investors in these text-to-image systems. "I'm not going to apologise for it … I won and I didn't break any rules," Allen, who is from Pueblo, Colorado, told The New York Times newspaper in an interview published on Friday. However, many have taken to social media to express their anger and despair over the award, arguing it took away from the hard work invested by humans to physically create noteworthy art.
