You’ll learn how to adapt a pre-trained ViT-B/16 model to a new domain using transfer learning. You’ll practice freezing and selectively unfreezing layers, explore how the model’s internal representations shift during fine-tuning, and document your choices in an experiment log. By the end, you’ll know how to unfreeze the final four transformer blocks, prepare your dataset effectively, and run a clean, reproducible training workflow that aligns with industry practice.

You’ll explore how learning-rate schedules shape the trajectory of model training. You’ll compare cosine decay and the one-cycle policy, analyze their signatures in training curves, and choose the schedule that maximizes validation accuracy while reducing training time. By the end, you’ll be able to interpret LR curves, diagnose plateaus or instability, and make informed decisions about training efficiency.

3个视频1篇阅读材料3个作业

Modern vision systems often combine multiple model components such as classification, object detection, and segmentation. Preparing these systems for production requires more than training individual models. Engineers must evaluate fine-tuning strategies, analyze model confidence behavior, assess detection performance against operational KPIs, and diagnose segmentation errors that may affect reliability. In this project, you will act as a computer vision engineer responsible for evaluating a multi-task vision system before deployment. You will analyze fine-tuning decisions, examine model calibration reliability, interpret detection metrics, diagnose segmentation weaknesses, and assess dataset quality before approving deployment readiness. The project integrates several core evaluation activities used in real-world vision engineering workflows. You will interpret training behavior to assess transfer learning strategies, analyze calibration metrics to improve prediction reliability, evaluate detection performance using task-specific KPIs, and diagnose segmentation errors through metric analysis and qualitative inspection. Rather than optimizing a single component, the project requires you to assess the entire vision pipeline and recommend coordinated improvements across tasks. Your final deliverable will be a Vision Model Evaluation & Refinement Report, a structured technical analysis that identifies weaknesses, prioritizes corrective actions, and justifies engineering decisions across classification, detection, and segmentation modules. This project mirrors real-world responsibilities of computer vision engineers who must evaluate multiple model components simultaneously and communicate a clear production-readiness recommendation to engineering and product stakeholders.
