Learning Rate and Batch Size Effects Visualizer for Deep Learning

Added Jun 2025 3 design docs

Ask a beginner why their network is not learning and the answer is usually hiding in two numbers: the learning rate and the batch size. Their effects are far easier to understand seen than described, and this project builds the tool that shows them clearly.

The intern creates a visualizer, developed in Jupyter with Keras and TensorFlow, that trains a small neural network on a compact dataset repeatedly under different learning rates and batch sizes, then plots the resulting training curves together for comparison. The characteristic patterns become recognizable at a glance: divergence when the rate is too high, glacial progress when it is too low, the noisy-but-fast trajectories of small batches versus the smooth ones of large batches. Users can adjust the settings and re-run experiments quickly enough to explore the space themselves and form their own rules of thumb.

The project builds diagnostic instinct — the ability to look at a loss curve and name the likely cause — which is among the most practical skills in deep learning. The intern also practices designing controlled experiments and communicating their results visually, habits that transfer directly to research and production work.

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.

Lightweight Text Generation API Built With LangServe

The gap between a working LangChain script and a service other software can call is deployment, and LangServe exists to close it: it turns chains into REST APIs with typed endpoints, streaming, and an interactive playground almost for free. Knowing this path from notebook to network service is essential for any developer who wants their AI work used by anyone other than themselves, and this project walks it end to end at a friendly scale. The intern builds a FastAPI project in Python that exposes a text generation chain through LangServe. The intern first constructs the chain itself with LangChain, a prompt template feeding a language model with configurable parameters such as topic and style, then mounts it as a LangServe route, gaining automatically generated endpoints for invocation, batching, and streaming. Around this core the intern adds a health check, request logging, and clear API documentation, then exercises the service from the built-in playground and from an external client script to prove the full round trip works. The project teaches deployment fundamentals for LLM applications: how chains become HTTP services, how FastAPI and LangServe divide responsibilities, what streaming responses look like on the wire, and how to structure a small AI service so that adding the next endpoint is easy, foundations the intern will reuse in every production AI role.

Population Health Trend Mining from Anonymized Records

Public health teams and hospital networks need to see the big picture in their records: which conditions are rising, how utilization shifts by season, and where demographic groups diverge in outcomes. Extracting those trends from large volumes of anonymized records is a classic distributed data problem, and this project walks an intern through solving it properly. Anonymized health records are ingested as a stream through Kafka, mirroring how events flow continuously from clinical systems, and stored in HDFS for scalable retention. PySpark batch jobs then process the accumulated data to extract trends, computing condition frequencies over time, admission patterns, and cohort-level summaries. Python scripts orchestrate the pipeline, manage the processing runs, and export CSV summaries suitable for epidemiologists and administrators. The deliverables are the pipeline and its data artifacts; there is no user interface, which keeps the focus on correctness, scale, and reproducibility. The intern finishes with practical big-data skills applied to healthcare: streaming ingestion, distributed storage and computation, and the habit of treating sensitive-domain data with the care that anonymization and aggregation demand.
