Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Mobile Image Classifier Optimization
BeginnerTake a standard MobileNetV2 model trained on ImageNet and optimize it using TensorFlow Lite or PyTorch Mobile for your own smartphone. Focus on applying post-training dynamic quantization and measuring the size and latency improvement.
Voice Keyword Spotter for Raspberry Pi
IntermediateBuild and optimize a small audio classification model (e.g., using MFCCs) to recognize wake words like 'Hey Siri' or 'OK Google' on a Raspberry Pi with a USB accelerator (Google Coral). Apply quantization-aware training to maintain accuracy.
Real-Time Object Detection on Jetson Nano
IntermediateOptimize an SSD or YOLO model for real-time detection on an NVIDIA Jetson Nano. Use TensorRT to apply INT8 quantization with calibration data from a webcam feed, achieving >15 FPS.
Quantized NLP Pipeline for Sentiment Analysis
AdvancedTake a BERT-tiny or DistilBERT model and quantize it for CPU inference. Deploy it as a REST API service that can handle batch requests with minimal latency, comparing the performance of ONNX Runtime vs. pure PyTorch.
End-to-Edge: Autonomous RC Car
AdvancedBuild an RC car that uses a quantized neural network to follow a lane or avoid obstacles, running entirely on a Raspberry Pi or Jetson. This involves collecting data, training a model, optimizing it, and integrating it with motor control and sensor fusion in a real-time loop.
