Labeling Experience

Data Science Intern (Remote) — RexC4 Technologies

OtherDocument

Clean, preprocess, and structure complex datasets to create high-integrity baseline inputs for downstream machine learning workflows. Identify statistical anomalies, outliers, and systemic bias, then apply analytical reasoning to correct data inconsistencies. Validate automated outputs against logical baselines to reduce false-positive rates in model-related evaluation pipelines. • Data preprocessing and structuring for ML-ready baselines • Statistical anomaly, outlier, and bias detection • Validation of automated outputs against logical baselines • Reduction of false-positive rates through QA checks
