I will build a fraud and anomaly detection model for your data
About this Gig
Hidden fraud, outliers, or unusual patterns in your data can cost real money if they go unnoticed. I'll build a custom anomaly detection model to flag suspicious transactions, records, or events in your dataset backed by real evaluation metrics, not vague claims.
What you get:
Data cleaning & preprocessing of your dataset
Anomaly detection using statistical methods or deep learning (autoencoder-based reconstruction error)
Flagged records report with confidence/anomaly scores
Clear visualizations of anomaly patterns
Optional: full deployment pipeline with source code
I've applied this exact approach on real transactional datasets (credit card-style fraud data), using autoencoder-based reconstruction error to catch patterns simple rule-based systems miss.
Best suited for: transaction/tabular numeric data financial transactions, insurance claims, sensor logs, user activity data.
Send me your dataset (CSV/Excel) and I'll get started right away. Message me first if you're unsure which package fits your data size.

FAQ
Q: What kind of data works best for this?
A: Structured/tabular numeric data — transaction logs, financial records, sensor readings. Text or image-based fraud detection needs a different approach — message me to discuss.
Q: Can you guarantee you'll catch all fraud/anomalies?
A: No system can guarantee 100% detection. I'll show you precision/recall metrics so you understand exactly how the model performs on your specific data.
Q: Do I need labeled data (i.e., data marked as "fraud" or "not fraud")?
A: Not required — unsupervised methods work without labels. If you do have labels, I can improve accuracy further and provide supervised evaluation metrics.
Q: Will I get the model file to reuse later?
A: Yes, Standard and Premium include full source code and the trained model file.
