Semantic-Drive: Democratizing Long-Tail Data Curation for Autonomous Vehicles
The development of robust Autonomous Vehicles (AVs) is significantly hindered by the scarcity of "Long-Tail" training data—rare, safety-critical events that are difficult and costly to identify in vast video logs. Traditional methods often lack precision or are privacy-invasive and expensive. Semantic-Drive introduces a groundbreaking local-first, neuro-symbolic framework designed to automate semantic data mining, making advanced data curation accessible and privacy-preserving.

Semantic-Drive addresses the critical "Dark Data" crisis in autonomous driving by transforming raw, unstructured video logs into a queryable semantic database. It provides a privacy-preserving, local-first solution for identifying rare, high-value scenarios without relying on costly or privacy-invasive cloud APIs.

Cost per 1k Frames (Local)
Compared to $30.00 for cloud-based solutions, Semantic-Drive reduces marginal curation costs by approximately 97%, enabling efficient and accessible data mining entirely on consumer hardware.
Semantic-Drive employs a novel Neuro-Symbolic Architecture that decouples perception into two stages: (1) Symbolic Grounding via a real-time open-vocabulary detector (YOLOE) to anchor attention, and (2) Cognitive Analysis via a Reasoning VLM for forensic scene analysis. This "System 2" approach significantly mitigates hallucination and small object blindness.

Semantic-Drive's ability to reason about rare object classes and static obstructions makes it ideal for discovering complex, safety-critical long-tail scenarios that traditional detectors often miss or misinterpret.
Case Study: Semantic Disambiguation (Wheelchair User)
Challenge: Standard open-vocabulary detectors often misclassify wheelchairs as "pedestrians" or "cyclists" due to visual overlap, leading to potential misassessments of risk.
Semantic-Drive's Solution: The Reasoning VLM correctly identifies the agent as a "wheelchair user" and contextualizes the risk of their presence in an active lane, demonstrating superior semantic fidelity over simple bounding-box classification. This precision is crucial for autonomous systems to accurately gauge vulnerability and kinetic dynamics.
Impact: Enhanced safety validation for vulnerable road users, preventing misclassification and ensuring appropriate vehicle responses.
Case Study: Static Hazard Recognition (Dumpster Obstruction)
Challenge: Traditional perception stacks often filter out static non-road objects as background noise, potentially ignoring critical Foreign Object Debris (FOD) that obstruct the drivable path.
Semantic-Drive's Solution: The system identifies a large dumpster as a critical Foreign Object Debris (FOD) event. The reasoning trace correctly deduces that the object's topology necessitates an immediate ego-vehicle stop, overriding the typical suppression of static obstacles and correctly assessing the high risk.
Impact: Improved hazard detection for static, non-road obstacles, preventing dangerous scenarios often overlooked by dynamic object trackers.
