DY0-001

About This Exam

DY0-001 is the exam for the CompTIA DataX certification (now called CompTIA DataAI), an expert-level certification in CompTIA's Xpert Series. It validates the ability to apply mathematics and statistics, covering hypothesis tests, ANOVA, ROC curves and AUC, confusion matrices, probability distributions, missing data and sampling, linear algebra, distance metrics and derivatives, and time series, survival analysis and causal inference; to model, analyze and report on data with exploratory data analysis, handling of sparsity, non-linearity, seasonality and outliers, feature engineering, scaling and transformation, model design, evaluation, selection and validation, and clear, accessible visualizations; to build machine learning models, from loss functions, regularization, cross-validation and data leakage to regression and classification, decision trees, random forests, bagging and boosting, neural networks and deep learning, and clustering and dimensionality reduction; to run data science operations and processes, including business requirements, compliance and KPIs, generated, synthetic and public data, data pipelines, streaming and lineage, data cleaning, merging, imputation and labeling, the data science life cycle with version control and testing, DevOps and MLOps with CI/CD, deployment and monitoring, and container, cloud, hybrid, edge and on-premises environments; and to use specialized applications of data science such as constrained and unconstrained optimization, natural language processing with tokenization, embeddings, TF-IDF and topic modeling, computer vision with OCR and object detection, graph analysis, reinforcement learning, fraud and anomaly detection and signal processing. It is for data scientists and other highly experienced data professionals with five or more years in data science or a similar role.
