文摘Dealing with data scarcity is the biggest challenge faced by Artificial Intelligence(AI),and it will be interesting to see how we overcome this obstacle in the future,but for now,“THE SHOW MUST GO ON!!!”As AI spreads and transforms more industries,the lack of data is a significant obstacle:the best methods for teaching machines how real-world processes work.This paper explores the considerable implications of data scarcity for the AI industry,which threatens to restrict its growth and potential,and proposes plausible solutions and perspectives.In addition,this article focuses highly on different ethical considerations:privacy,consent,and non-discrimination principles during AI model developments under limited conditions.Besides,innovative technologies are investigated through the paper in aspects that need implementation by incorporating transfer learning,few-shot learning,and data augmentation to adapt models so they could fit effective use processes in low-resource settings.This thus emphasizes the need for collaborative frameworks and sound methodologies that ensure applicability and fairness,tackling the technical and ethical challenges associated with data scarcity in AI.This article also discusses prospective approaches to dealing with data scarcity,emphasizing the blend of synthetic data and traditional models and the use of advanced machine learning techniques such as transfer learning and few-shot learning.These techniques aim to enhance the flexibility and effectiveness of AI systems across various industries while ensuring sustainable AI technology development amid ongoing data scarcity.
文摘BACKGROUND Autoimmune myocarditis(AM)associated with autoimmune diseases can cause complete atrioventricular block(CAVB),but the related autoantigens and the underlying mechanisms are unclear.Anti-SSA/Ro antibodies may play an important role in this process,but cases of AM with positive anti-SSA/Ro antibodies are rare.In addition,arrhythmias,such as atrioventricular block,are very common in patients with autoimmune diseases,but severe atrioventricular block requiring permanent pacemaker implantation is extremely rare.CASE SUMMARY The patient in this case had AM with anti-SSA/Ro antibody positivity,which was associated with connective tissue disease,and the patient subsequently developed CAVB.After intensive immunosuppressive therapy,the antibody test results became negative,and pulmonary hypertension significantly improved.However,the outcome of permanent pacemaker implantation did not change.CONCLUSION In clinical practice,the awareness of adult AM associated with autoimmune diseases combined with CAVB should be strengthened in clinicians,and anti-SSA/Ro antibodies may play a role in this process.Therefore,improving the detection of antibodies and early intervention,such as active immunosuppression therapy,may be very important for improving disease prognosis.For patients who do not respond to immunosuppressive therapy,implantation of a permanent pacemaker may become an essential treatment option.
文摘BACKGROUND Kidney and liver transplantation are two sub-specialized medical disciplines,with transplant professionals spending decades in training.While artificial intelligencebased(AI-based)tools could potentially assist in everyday clinical practice,comparative assessment of their effectiveness in clinical decision-making remains limited.AIM To compare the use of ChatGPT and GPT-4 as potential tools in AI-assisted clinical practice in these challenging disciplines.METHODS In total,400 different questions tested ChatGPT’s/GPT-4 knowledge and decision-making capacity in various renal and liver transplantation concepts.Specifically,294 multiple-choice questions were derived from open-access sources,63 questions were derived from published open-access case reports,and 43 from unpublished cases of patients treated at our department.The evaluation covered a plethora of topics,including clinical predictors,treatment options,and diagnostic criteria,among others.RESULTS ChatGPT correctly answered 50.3%of the 294 multiple-choice questions,while GPT-4 demonstrated a higher performance,answering 70.7%of questions(P<0.001).Regarding the 63 questions from published cases,ChatGPT achieved an agreement rate of 50.79%and partial agreement of 17.46%,while GPT-4 demonstrated an agreement rate of 80.95%and partial agreement of 9.52%(P=0.01).Regarding the 43 questions from unpublished cases,ChatGPT demonstrated an agreement rate of 53.49%and partial agreement of 23.26%,while GPT-4 demonstrated an agreement rate of 72.09%and partial agreement of 6.98%(P=0.004).When factoring by the nature of the task for all cases,notably,GPT-4 demonstrated outstanding performance,providing a differential diagnosis that included the final diagnosis in 90%of the cases(P=0.008),and successfully predicting the prognosis of the patient in 100%of related questions(P<0.001).CONCLUSION GPT-4 consistently provided more accurate and reliable clinical recommendations with higher percentages of full agreements both in renal and liver transplantation compared with ChatGPT.Our findings support the potential utility of AI models like ChatGPT and GPT-4 in AI-assisted clinical practice as sources of accurate,individualized medical information and facilitating decision-making.The progression and refinement of such AI-based tools could reshape the future of clinical practice,making their early adoption and adaptation by physicians a necessity.

文摘Feature selection(FS)is a pivotal pre-processing step in developing data-driven models,influencing reliability,performance and optimization.Although existing FS techniques can yield high-performance metrics for certain models,they do not invariably guarantee the extraction of the most critical or impactful features.Prior literature underscores the significance of equitable FS practices and has proposed diverse methodologies for the identification of appropriate features.However,the challenge of discerning the most relevant and influential features persists,particularly in the context of the exponential growth and heterogeneity of big data—a challenge that is increasingly salient in modern artificial intelligence(AI)applications.In response,this study introduces an innovative,automated statistical method termed Farea Similarity for Feature Selection(FSFS).The FSFS approach computes a similarity metric for each feature by benchmarking it against the record-wise mean,thereby finding feature dependencies and mitigating the influence of outliers that could potentially distort evaluation outcomes.Features are subsequently ranked according to their similarity scores,with the threshold established at the average similarity score.Notably,lower FSFS values indicate higher similarity and stronger data correlations,whereas higher values suggest lower similarity.The FSFS method is designed not only to yield reliable evaluation metrics but also to reduce data complexity without compromising model performance.Comparative analyses were performed against several established techniques,including Chi-squared(CS),Correlation Coefficient(CC),Genetic Algorithm(GA),Exhaustive Approach,Greedy Stepwise Approach,Gain Ratio,and Filtered Subset Eval,using a variety of datasets such as the Experimental Dataset,Breast Cancer Wisconsin(Original),KDD CUP 1999,NSL-KDD,UNSW-NB15,and Edge-IIoT.In the absence of the FSFS method,the highest classifier accuracies observed were 60.00%,95.13%,97.02%,98.17%,95.86%,and 94.62%for the respective datasets.When the FSFS technique was integrated with data normalization,encoding,balancing,and feature importance selection processes,accuracies improved to 100.00%,97.81%,98.63%,98.94%,94.27%,and 98.46%,respectively.The FSFS method,with a computational complexity of O(fn log n),demonstrates robust scalability and is well-suited for datasets of large size,ensuring efficient processing even when the number of features is substantial.By automatically eliminating outliers and redundant data,FSFS reduces computational overhead,resulting in faster training and improved model performance.Overall,the FSFS framework not only optimizes performance but also enhances the interpretability and explainability of data-driven models,thereby facilitating more trustworthy decision-making in AI applications.

文摘Embodied intelligence represents a new paradigm for the cross-integration development of artificial intelli⁃gence.By endowing AI with a"physical body",it enables interaction with the real world,allowing AI to move beyond digital environments into the physical realm and demonstrate intelligence that simulates or even surpasses human capa⁃bilities.Although embodied artificial intelligence demonstrates substantial potential in the realm of invention and cre⁃ation,there remain challenges in obtaining patent authorization for its generated technical solutions,specifically con⁃cerning subject,object,and market aspects.To address these issues,the feasibility of the subject should be demon⁃strated from the perspective of embodied cognition theory,while the object should be justified from a techno-centric standpoint.Subsequently,a regulatory framework for the patentability of technical solutions generated by embodied in⁃telligence should be proposed.First,a more inclusive subject framework should be established,recognizing embodied artificial intelligence as an inventor alongside humans,thereby affirming a coexistent"inventor"identity.Second,pat⁃ent rights should be assigned to developers of embodied artificial intelligence,referencing the rights distribution para⁃digm under employment relationships.Third,the criteria for patent eligibility and the"three-aspect"examination stan⁃dards should be refined.Finally,mechanisms for optimizing the implementation of rights and risk prevention should be developed.

文摘Objectives Nurses’clinical research activities have contributed to optimizing the care process and improving patient outcomes,and generative artificial intelligence(GAI)may help clinical nurses strengthen their research skills.To support research,this study aimed to explore the Chinese nurses’perceptions and experiences of GAI training.Methods This study used a descriptive qualitative design.The China Nurses Network conducted a three-day training session on“GAI for Nursing Research”theme,we selected 23 nurses by a convenience sampling method among participating in the training.The researchers conducted three focus group interviews at the end of each day.All focus groups were interviewed face-to-face to facilitate interaction,data collection,and observation.The data were analyzed using conventional content analysis and coded manually.Results The results showed that nurses’use of GAI to support scientific research was dynamic and characterized by evolving perceptions and practices.Four themes and 11 sub-themes emerged from the analysis:1)utilization efficacy:cope with research ability,affected by many factors;2)booster research:growth and challenges go hand in hand;3)role reversal:from GAI-dominated to nurse-dominated;4)beautiful dream:more features on research,more assistants on clinical care.Conclusions The effectiveness of GAI in supporting clinical nurses in conducting research is mainly limited by differences in personal research literacy,lack of ethical regulation,and information accuracy.In the future,it is necessary to improve nurses’relevant skills through specialized training and promote the standardization of technical regulations to ensure the appropriate application of GAI in nursing research.
文摘Amid the global wave of digital economy,China's medical artificial intelligence applications are rapidly advancing through technological innovation and policy support,while facing multifaceted evaluation and regulatory challenges.The dynamic algorithm evolution undermines the consistency of assessment criteria,multimodal systems lack unified evaluation metrics,and conflicts persist between data sharing and privacy protection.To address these issues,the China National Health Development Research Center has established a value assessment framework for artificial intelligence medical technologies,formulated the country's first technical guideline for clinical evaluation,and validated their practicality through scenario-based pilot studies.Furthermore,this paper proposes introducing a"regulatory sandbox"model to test technical compliance in controlled environments,thereby balancing innovation incentives with risk governance.
文摘The digital transformation of international Chinese language education is an important direction for enhancing the global dissemination effectiveness of the Chinese language.In teaching Chinese as a second language,writing,as a form of higher-order language output,has long faced challenges such as insufficient teacher resources,lagging feedback,and a lack of personalized support.Generative artificial intelligence(GAI)offers a new path for teaching Chinese writing.This study,with intermediate Chinese learners as the subjects,systematically explores the effectiveness of GAI-assisted Chinese writing instruction through a combination of controlled experiments and interviews based on a Chinese learning platform embedded with GAI.The study found that the GAI class was significantly superior to the traditional class in terms of the adequacy dimension of content quality and the grammatical and lexical dimensions of language quality;teachers and GAI play complementary roles in this process;most Chinese learners have a positive attitude towards this model.Based on the above findings,this study presents three suggestions:using GAI to empower Chinese writing instruction,giving full play to the complementary advantages of human and machine,and enhancing the AI literacy of teachers and students to achieve two-way empowerment of human and machine,with the aim of promoting the intelligent development of international Chinese education.
文摘This study focuses on the construction and application of intelligent financial decision-making models driven by generative artificial intelligence(AI).It analyzes the mechanisms by which generative AI empowers financial decision-making within a dual framework of dynamic knowledge evolution and risk control.The research reveals that generative AI,with its superior data processing,pattern recognition,and autonomous learning capabilities,can transcend the limitations of traditional decision-making models,facilitating a significant shift from causal inference to probabilistic creation in decision-making paradigms.By systematically constructing an intelligent financial decision-making model that includes data governance,core engine,and decision output layers,the study clarifies the functional roles and collaborative mechanisms of each layer.Additionally,it addresses key challenges in technology application,institutional adaptation,and organizational transformation by proposing systematic strategies for technical risk management,institutional innovation,and organizational capability enhancement,aiming to provide robust theoretical support and practical guidance for the intelligent transformation of corporate financial decision-making.
文摘The rapid development of generative artificial intelligence(GenAI)is profoundly changing the form and paradigm of foreign language education.GenAI technology,represented by DeepSeek,provides technical support for personalization,immersion,and intelligence of foreign language teaching by virtue of its natural language processing,multimodal content generation,and cross-cultural simulation capabilities.From the three dimensions of“teaching reconstruction,”“learning innovation,”and“education upgrading,”this paper systematically analyzes the internal mechanism of GenAI empowering foreign language education and reveals its unique value in language knowledge transmission,skill training,and cultural understanding.At the same time,considering that GenAI may lead to language model errors in foreign language education,cultural misinterpretations,technological dependence,and data privacy risks,it is proposed to adopt coping strategies such as building an advanced literacy system,establishing a human-AI collaborative ecosystem,and implementing a transparent regulatory framework for algorithms.These measures aim to ensure the high-quality development of technology-integrated foreign language education,providing both theoretical support and practical pathways for cultivating globally competent talents with intercultural communication skills and digital literacy.

文摘This paper uses an innovative improved artificial bee colony(IABC)algorithm to aid in the fabrication of a highly responsive phasemodulation surface plasmon resonance(SPR)biosensor.In this biosensor’s sensing structure,a double-layer Ag-Au metal film is combined with a blue phosphorene/transition metal dichalcogenide(BlueP/TMDC)hybrid structure and graphene.In the optimization function of the IABC method,the reflectivity at resonance angle is incorporated as a constraint to achieve high phase sensitivity.The performance of the Ag-Au-BlueP/TMDC-graphene heterostructure as optimized by the IABC method is compared with that of a similar structure optimized using the traditional ABC algorithm.The results indicate that optimization using the IABC method gives significantly more phase sensitivity,together with lower reflectivity,than can be achieved with the traditional ABC method.The highest phase sensitivity of 3.662×10^(6) °/RIU is achieved with a bilayer of BlueP/WS2 and three layers of graphene.Moreover,analysis of the electric field distribution demonstrates that the optimal arrangement can be utilized for enhanced detection of small biomolecules.Thus,given the exceptional sensitivity achieved,the proposed method based on the IABC algorithm has great promise for use in the design of high-performance SPR biosensors with a variety of multilayer structures.

文摘The relationship between the neighborhood environment and well-being is attracting increasingly attention from researchers and policymakers,as the goal of development has shift from economy to well-being.However,existing literature predominantly adopts the utilitarian approach,understanding well-being as people’s feelings about their lives and viewing the neighborhood environment as resources that benefit well-being.The Capability Approach,a novel approach that conceptualize well-being as the freedoms to do or to be and regard environment as conversion factors that influence well-being,can offer new lens by incorporating human development in-to these topics.This paper proposes an alternative theoretical framework:well-being is conceptualized and measured by capability;neighborhood environment affects well-being by providing spatial services,functioning as environmental conversion factors,and serving as social conversion factors.We conducted a case study of Changshu City located in eastern China,utilizing multiple resource data,applying explainable artificial intelligence(XAI),namely eXtreme Gradient Boosting(XGBoost)and SHapley Additive exPlana-tions(SHAP).Our findings highlight the significance of viewing the neighborhood environment as a set of conversion factors,as it provides more explanatory power than providing spatial services.Compared to conventional research based on linear relationship as-sumption,our results demonstrate that the effects of neighborhood environment on well-being are non-linear,characterized by threshold effects and interaction effects.These insights are crucial for informing urban planning and public policy.This research enriches our un-derstanding of well-being,neighborhood environment,and their relationship as well as provides empirical evidence for the core concept of conversion factors in the capability approach.
