Beginner Transfer Learning Lab with MobileNet and ResNet

Added Jun 2025 3 design docs

Training an image classifier from scratch requires data and compute that beginners rarely have, which is why transfer learning, reusing networks pre-trained on millions of images, is the technique that actually unlocks practical computer vision for newcomers. Yet the concept stays abstract until a learner sees a pre-trained model classify their own photographs correctly.

The intern builds a Streamlit application that makes transfer learning tangible: users upload any image and classify it using pre-trained MobileNet or ResNet models loaded through TensorFlow. The app displays the top predicted classes with confidence scores and lets users switch between the two architectures on the same image to compare their answers and inference speed. The intern implements the specific preprocessing each network expects, presents results clearly, and adds explanatory content describing what the models were trained on and why their knowledge transfers to new images, turning the app into a genuine self-serve lesson.

Completing the lab gives the intern a working understanding of pre-trained architectures and the trade-off between lightweight and heavyweight models, practical TensorFlow inference skills, and a deployed Python application demonstrating they can make advanced ideas accessible, a foundation for the fine-tuning projects that come next.

Crop Disease Classification Service Using Transfer Learning

Crop diseases are often identified too late for effective intervention because farmers and field agronomists rarely have quick access to plant pathology expertise. A photograph of a diseased leaf contains enough signal for accurate diagnosis, but turning that signal into a dependable, scalable service is a genuine engineering challenge for agricultural research groups. The intern builds a full diagnostic platform around transfer learning: pre-trained ResNet and MobileNet backbones are fine-tuned in PyTorch on crop disease imagery, with OpenCV and NumPy handling preprocessing and a data augmentation pipeline improving robustness to lighting and orientation. A Streamlit interface lets users upload leaf photos and receive ranked disease predictions alongside explainable AI visualizations that highlight the image regions driving each classification, while a FastAPI service exposes a batch inference endpoint for research workloads and pandas powers summary reporting. The entire system is containerized with Docker so it can be deployed consistently across lab and cloud environments. The project demonstrates end-to-end applied computer vision: adapting pre-trained networks to a specialist domain, communicating model reasoning to non-technical users, and packaging research code as a deployable, reproducible service.

Contour Detection Teaching Tool with Bounding Box Overlays

Contour detection is the workhorse behind shape analysis, object counting, and document scanning, yet learners often struggle to connect the algorithm's parameters to what actually appears on screen. An interactive environment where every setting change immediately redraws the result turns a confusing API into an understandable process. The intern builds a Streamlit application where users upload an image and OpenCV finds and draws its contours in real time. The tool walks through the full pipeline the technique requires: grayscale conversion, thresholding or edge detection to produce a binary image, contour extraction, and finally rendering, with the intern drawing both the raw contour outlines and fitted bounding boxes around each detected shape. Controls let users adjust retrieval modes and approximation methods, filter contours by area to suppress noise, and read out per-contour measurements such as area and perimeter computed from the geometry. The project teaches the intern how classical shape analysis actually works beneath convenience functions, builds solid skills in OpenCV image preprocessing and Python, and demonstrates an ability valued in any technical role: taking a concept that confuses newcomers and building the tool that makes it click.

Prompt Template Design and Testing Workbench for Educators

Teachers and instructional designers increasingly build AI-driven learning modules, such as quiz generators, explanation assistants, and feedback tools, and every one of them lives or dies by its prompts. Yet educators typically iterate on prompts by trial and error in a chat window, with no way to save what worked, compare variations, or enforce consistent output formats. Prompt engineering needs a workbench, the way code has an IDE. The intern builds that workbench as a Streamlit application in Python, using LangChain as the engine. The tool lets users create parameterized prompt templates with variables such as subject, difficulty, and student level; run them against OpenAI models; and compare outputs across template variations side by side. Output parsers enforce structured results, so a quiz template reliably yields well-formed questions and answers rather than loose prose, and chain sequencing lets users compose multi-step flows in which one prompt's output feeds the next, mirroring how real learning modules are assembled. The intern implements template storage, the comparison runner, and the parser configuration interface. The project demonstrates systematic prompt engineering as a discipline: template design, structured output enforcement, chain composition, and building a tool that turns an ad hoc craft into a repeatable process for a non-technical audience.
