Towards Inter-character Relationship-driven Story Generation

arXiv.org Artificial Intelligence

In this paper, we introduce the task of modeling interpersonal relationships for story generation. For addressing this task, we propose Relationships as Latent Variables for Story Generation, (ReLiSt). ReLiSt generates stories sentence by sentence and has two major components - a relationship selector and a story continuer. The relationship selector specifies a latent variable to pick the relationship to exhibit in the next sentence and the story continuer generates the next sentence while expressing the selected relationship in a coherent way. Our automatic and human evaluations demonstrate that ReLiSt is able to generate stories with relationships that are more faithful to desired relationships while maintaining the content quality. The relationship assignments to sentences during inference bring interpretability to ReLiSt.


Deep Virtual-to-Real Distillation for Pedestrian Crossing Prediction

arXiv.org Artificial Intelligence

Pedestrian crossing is one of the most typical behavior which conflicts with natural driving behavior of vehicles. Consequently, pedestrian crossing prediction is one of the primary task that influences the vehicle planning for safe driving. However, current methods that rely on the practically collected data in real driving scenes cannot depict and cover all kinds of scene condition in real traffic world. To this end, we formulate a deep virtual to real distillation framework by introducing the synthetic data that can be generated conveniently, and borrow the abundant information of pedestrian movement in synthetic videos for the pedestrian crossing prediction in real data with a simple and lightweight implementation. In order to verify this framework, we construct a benchmark with 4667 virtual videos owning about 745k frames (called Virtual-PedCross-4667), and evaluate the proposed method on two challenging datasets collected in real driving situations, i.e., JAAD and PIE datasets. State-of-the-art performance of this framework is demonstrated by exhaustive experiment analysis. The dataset and code can be downloaded from the website \url{http://www.lotvs.net/code_data/}.


FRSUM: Towards Faithful Abstractive Summarization via Enhancing Factual Robustness

arXiv.org Artificial Intelligence

Despite being able to generate fluent and grammatical text, current Seq2Seq summarization models still suffering from the unfaithful generation problem. In this paper, we study the faithfulness of existing systems from a new perspective of factual robustness which is the ability to correctly generate factual information over adversarial unfaithful information. We first measure a model's factual robustness by its success rate to defend against adversarial attacks when generating factual information. The factual robustness analysis on a wide range of current systems shows its good consistency with human judgments on faithfulness. Inspired by these findings, we propose to improve the faithfulness of a model by enhancing its factual robustness. Specifically, we propose a novel training strategy, namely FRSUM, which teaches the model to defend against both explicit adversarial samples and implicit factual adversarial perturbations. Extensive automatic and human evaluation results show that FRSUM consistently improves the faithfulness of various Seq2Seq models, such as T5, BART.


Write It Like You See It: Detectable Differences in Clinical Notes By Race Lead To Differential Model Recommendations

arXiv.org Artificial Intelligence

Clinical notes are becoming an increasingly important data source for machine learning (ML) applications in healthcare. Prior research has shown that deploying ML models can perpetuate existing biases against racial minorities, as bias can be implicitly embedded in data. In this study, we investigate the level of implicit race information available to ML models and human experts and the implications of model-detectable differences in clinical notes. Our work makes three key contributions. First, we find that models can identify patient self-reported race from clinical notes even when the notes are stripped of explicit indicators of race. Second, we determine that human experts are not able to accurately predict patient race from the same redacted clinical notes. Finally, we demonstrate the potential harm of this implicit information in a simulation study, and show that models trained on these race-redacted clinical notes can still perpetuate existing biases in clinical treatment decisions.


Machine learning can guide experimental approaches for protein digestibility estimations

arXiv.org Artificial Intelligence

Food protein digestibility and bioavailability are critical aspects in addressing human nutritional demands, particularly when seeking sustainable alternatives to animal-based proteins. In this study, we propose a machine learning approach to predict the true ileal digestibility coefficient of food items. The model makes use of a unique curated dataset that combines nutritional information from different foods with FASTA sequences of some of their protein families. We extracted the biochemical properties of the proteins and combined these properties with embeddings from a Transformer-based protein Language Model (pLM). In addition, we used SHAP to identify features that contribute most to the model prediction and provide interpretability. This first AI-based model for predicting food protein digestibility has an accuracy of 90% compared to existing experimental techniques. With this accuracy, our model can eliminate the need for lengthy in-vivo or in-vitro experiments, making the process of creating new foods faster, cheaper, and more ethical.


Use artificial intelligence to combat climate change

#artificialintelligence

Recent reports from the Intergovernmental Panel on Climate Change (IPCC) show that climate change is affecting every region of our planet and that some of the changes -- such as rising temperatures and sea levels -- can only be arrested, but are irreversible. Part of the problem stems from how complex an issue climate change is. It has scientific and economic elements and sociopolitical and ethical ones, and it requires cooperation on a scale hitherto unseen. Halting climate change and responding to the effects of the damage already wrought requires two approaches. The first is mitigation, namely trying to remove carbon dioxide from the atmosphere while reducing emissions.

Turkey promises to keep grain moving despite Russian withdrawal

Al Jazeera

Turkey says it is determined that Ukraine continues its food exports despite Russia announcing its withdrawal from a UN-brokered grain deal, a move that has heightened concerns for nations desperate for food assistance. Russia pulled out of the deal on Saturday after what it said was a major Ukrainian drone attack on its naval fleet in annexed Crimea. Despite Moscow's decision, cargo ships set sail carrying 354,500 tonnes of grain, the most dispatched in one day since the programme began in August. Turkey, which helped broker the agreement, remained committed to the deal. "Even if Russia behaves hesitantly because it didn't receive the same benefits, we will continue decisively our efforts to serve humanity," President Recep Tayyip Erdogan said.


Explosions Rock Kyiv Days After Russia Blames Ukraine For Black Sea Attack

International Business Times

Several blasts shook Kyiv on Monday, days after Russia blamed Ukraine for drone attacks on its Crimea fleet in the Black Sea. At least five explosions were heard in the Ukrainian capital between 8:00 am (0600 GMT) and 8:20 am, according to AFP journalists. Kyiv had already been hit on October 10 and 17 by drones. After Monday's blasts, mayor Vitali Klitschko said in a Telegram message: "An area of Kyiv is without electricity and certain areas without water following Russian strikes." Monday's attack on the Ukrainian capital comes after Russia pulled out of a landmark agreement that allowed vital grain shipments via a maritime safety corridor.


Artificial Intelligence to play major role in patient care

#artificialintelligence

Nellore: The conference on Futuristic Nursing being held at Narayana Nursing College here has discussed at length aspects of patient safety as also use of artificial intelligence and tele-medicine, apart from mobile health and sensor-based technologies (smartphones, smartphone apps and wearable technologies). More than 800 nurses are participating in the meet and around 40 eminent nursing leaders across the globe discussing the latest in nursing practices during the 3-day conference from Saturday. In a paper on'Artificial Intelligence in Nursing' presented jointly by Dr Ramesh M.Sc Phd, HoD Medical Surgical Nursing, St Paul's Hospital Millennium Medical College, Ethiopia, and Dr S. Indira, Dean of Narayana Nursing College, said AI offers three advantages over traditional methods -- the ability to quickly consider large volumes of data in risk prediction, increased intervention specificity (accurately flagging patients most at-risk) and automated adjustments in variable selection and calculation. "AI can help detect which patient features are most important in public health applications, allowing for more focused preventive interventions. Robots may aid nursing care tasks in hazardous clinical environments and they have the potential to automate some tasks."
