Image Classification for Manufacturing Defects
Pyre Sparkcompleted

Build a computer vision model that identifies manufacturing defects in electronic component photographs from assembly line cameras. The model must classify defects into 8 categories (scratch, crack, dent, discoloration, missing_pin, solder_bridge, correct, unknown) with at least 95% accuracy. Must be deployable on edge devices with < 50MB model size and run inference under 100ms per image on CPU.

Real-Time Anomaly Detection for IoT Sensors
Pyre Sparkcompleted

Build a streaming anomaly detection system for industrial IoT sensor data. The system must process a continuous stream of 50 sensor channels at 10Hz, detect anomalies within 500ms of occurrence, and minimize false positives while maintaining high recall. Will be deployed on edge hardware with limited compute.

Optimize RAG Pipeline for Legal Documents
Pyre Sparkcompleted

Given a corpus of 10,000 legal contracts, build a Retrieval-Augmented Generation pipeline that accurately answers natural language questions about specific clauses, obligations, and deadlines. The system must handle cross-document references, resolve ambiguous pronouns to correct entities, and provide exact source citations (document ID + page number) for every answer.
