Building high-performing computer vision systems requires more than training a model—it requires careful evaluation, reliable predictions, and continuous refinement. In this course, you'll learn how to fine-tune and evaluate computer vision models used in real-world AI systems.
You'll begin by applying transfer learning techniques to improve model accuracy on domain-specific datasets and analyzing learning-rate schedules to understand training behavior. Next, you'll evaluate the calibration of classification models and apply post-hoc correction methods to improve prediction reliability.
The course also explores data preparation and annotation practices for object detection. You'll analyze object-size distributions to configure anchor boxes and evaluate detector performance using standard metrics.
Finally, you'll examine image segmentation models. You'll learn how to address class imbalance, analyze segmentation errors, and apply post-processing techniques to improve prediction quality.
By the end of the course, you'll be able to evaluate, diagnose, and refine computer vision models across classification, detection, and segmentation tasks.
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.

Project: Vision Model Evaluation & Refinement Report
Module 13•1 hour to complete
Module details
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.
