Will AI be a threat to our jobs? Can we trust the judgment of AI systems? Not yet, AI technology may inherit human biases due to biases in training data In this article, we focus on AI bias and will answer all important questions regarding biases in artificial intelligence algorithms from types and examples of AI biases to removing those biases from AI algorithms. What is AI bias? AI bias is an anomaly in the output of machine learning algorithms, due to the prejudiced assumptions made during the algorithm development process or prejudices in the training data. What are the types of AI bias? More than 180 human biases have been defined and classified by psychologists. Cognitive biases could seep into machine learning algorithms via either designers unknowingly introducing them to the model a training data set which includes those biases Lack of complete data: If data is not complete, it may not be representative and therefore it may include bias. For example, most psychology research studies include results from undergraduate students which are a specific group and do not represent the whole population. Figure 1. Technically, yes.
An AI system can be as good as the quality of its input data. If you can clean your training dataset from conscious and unconscious assumptions on race, gender, or other ideological concepts, you are able to build an AI system that makes unbiased data-driven decisions. AI can be as good as data and people are the ones who create data. There are numerous human biases and ongoing identification of new biases is increasing the total number constantly.

Automated labelling processes using natural language processing tools can also introduce bias if not carefully monitored. Label ambiguity, where multiple conflicting labels exist for the same data, further complicates the issue. Additionally, label bias occurs when the available labels do not fully represent the diversity of the data, leading to incomplete or biassed model training. Care must be taken when using publicly available datasets, as they may contain unknown biases in labelling schemas. Overall, understanding and addressing these various sources of bias is essential for developing fair and reliable AI models for medical imaging. Guarding Against Bias in AI Model Development In model development, preventing data leakage is crucial during data splitting to ensure accurate evaluation and generalisation. Data leakage occurs when information not available at prediction time is included in the training dataset, such as overlapping training and test data. This can lead to falsely inflated performance during evaluation and poor generalisation to new data. Data duplication and missing data are common causes of leakage, as redundant or global statistics may unintentionally influence model training. Improper feature engineering can also introduce bias by skewing the representation of features in the training dataset. For instance, improper image cropping may lead to over- or underrepresentation of certain features, affecting model predictions. For example, a mammogram model trained on cropped images of easily identifiable findings may struggle with regions of higher breast density or marginal areas, impacting its performance. Proper feature selection and transformation are essential to enhance model performance and avoid biassed development. Model Evaluation: Choosing Appropriate Metrics and Conducting Subgroup Analysis In model evaluation, selecting appropriate performance metrics is crucial to accurately assess model effectiveness. Metrics such as accuracy may be misleading in the context of class imbalance, making the F1 score a better choice for evaluating performance. Precision and recall, components of the F1 score, offer insights into positive predictive value and sensitivity, respectively, which are essential for understanding model performance across different classes or conditions. Subgroup analysis is also vital for assessing model performance across demographic or geographic categories. Evaluating models based solely on aggregate performance can mask disparities between subgroups, potentially leading to biassed outcomes in specific populations. Conducting subgroup analysis helps identify and address poor performance in certain groups, ensuring model generalizability and equitable effectiveness across diverse populations. Addressing Data Distribution Shift in Model Deployment for Reliable Performance In model deployment, data distribution shift poses a significant challenge, as it reflects discrepancies between the training and real-world data. Models trained on one distribution may experience declining performance when deployed in environments with different data distributions. Covariate shift, the most common type of data distribution shift, occurs when changes in input distribution occur due to shifting independent variables, while the output distribution remains stable. This can result from factors such as changes in hardware, imaging protocols, postprocessing software, or patient demographics. Continuous monitoring is essential to detect and address covariate shift, ensuring model performance remains reliable in real-world scenarios. Mitigating Social Bias in AI Models for Equitable Healthcare Applications Social bias can permeate throughout the development of AI models, leading to biassed decision-making and potentially unequal impacts on patients.

Необходим грамотно подготовленный и ответственный персонал. Все изделия, задействованные в холодовой цепи, должны быть зарегистрированы в Росздравнадзоре в качестве изделий медицинского назначения и соответствующим образом сертифицированы, а термометры для контроля температуры в холодильниках должны быть внесены в реестр средств измерений и проходить периодическую поверку. Что такое инспекционная метка и зачем она нужна? Сколько раз нажмёте — столько меток будет на графике в таблице , привязанных по календарному времени к моменту нажатия. Это очень удобная функция, например, для разграничения зон ответственности при транспортировке лекарственных средств.
В каждом пункте перегрузки и временного хранения могут формироваться такие метки с целью последующего наглядного анализа момента нарушения холодовой цепи, и установления причины кто виноват? Следует иметь ввиду, что и электронный итоговый отчёт формируется с учётом этих «инспекционных меток». В случае хранения лекарственных средств как у Вас на складе , «инспекционные метки» позволяют, например, дисциплинировать сотрудников, осуществляющих ежесуточный контроль 2 раза в сутки состояния индикаторов. Если сотрудник будет нажимать кнопку МЕТКА при осмотре состояния ТИ, то при считывании информации раз в неделю в ПК сразу будет видно — осуществлялся контроль, или нет.
Биас может быть вызван различными факторами, такими как предрассудки, стереотипы, социокультурные влияния или даже просто интуитивная оценка. Он может присутствовать в различных областях, таких как психология, медицина, право, политика и научное исследование. В контексте принятия решений биас может влиять на нашу способность анализировать информацию объективно и приводить к неправильным или несбалансированным результатам.
Journalist Why is the resolution of the European Parliament called biased? The recent resolution passed by the European Parliament condemning alleged human rights violations in Azerbaijan has sparked a sharp response from Azerbaijani authorities, who have dismissed the document as biased and politically motivated. The resolution, adopted with 474 votes in favor, 4 against, and 51 abstentions, also urged the European Commission to consider suspending the strategic partnership with Azerbaijan in the energy sector and reiterated calls for EU sanctions against Azerbaijani officials implicated in human rights abuses. In response, the Milli Majlis of Azerbaijan issued a statement denouncing the European Parliament resolution as biased and lacking objectivity.
