What are the two parts of the TensorFlow for Poets Code Labs, and what do they cover in terms of MobileNet image classification?
The TensorFlow for Poets Code Labs consist of two parts: "Image Classification with TensorFlow" and "TensorFlow for Poets 2: Optimize for Mobile". These code labs provide a comprehensive introduction to image classification using TensorFlow and demonstrate how to optimize the trained models for mobile devices using TensorFlow Lite and the MobileNet architecture.
In the first part, "Image Classification with TensorFlow," participants learn the basics of TensorFlow and how to build an image classifier using a pre-trained model. The code lab covers the following key concepts and steps:
1. Importing the necessary libraries and dependencies: TensorFlow, NumPy, and Matplotlib.
2. Loading the pre-trained Inception v3 model provided by TensorFlow Hub.
3. Preprocessing the input images to match the expected input format of the Inception v3 model.
4. Running the pre-trained model on the input images to obtain predictions.
5. Visualizing the predictions and interpreting the results.
This part of the code lab provides a solid foundation in TensorFlow and image classification techniques. Participants gain hands-on experience in building an image classifier using a pre-trained model, which can be further customized and fine-tuned for specific tasks.
The second part, "TensorFlow for Poets 2: Optimize for Mobile," focuses on optimizing the trained image classifier for deployment on mobile devices using TensorFlow Lite. Participants learn how to convert the TensorFlow model into a TensorFlow Lite model and deploy it on a mobile app. The code lab covers the following steps:
1. Retraining the image classifier using a custom dataset.
2. Exporting the retrained model as a TensorFlow SavedModel.
3. Converting the SavedModel to a TensorFlow Lite model using the TensorFlow Lite Converter.
4. Integrating the TensorFlow Lite model into an Android app using the TensorFlow Lite Android Support Library.
5. Running the app on a mobile device and testing the image classification capabilities.
This part of the code lab enables participants to take their trained image classifier and deploy it on mobile devices, making it accessible and usable in real-world scenarios. The optimization process using TensorFlow Lite ensures efficient execution and minimal resource consumption on mobile devices.
In terms of MobileNet image classification, both parts of the code lab utilize the MobileNet architecture. MobileNet is a lightweight deep neural network architecture specifically designed for mobile and embedded vision applications. It provides a good balance between model size and accuracy, making it well-suited for image classification tasks on resource-constrained devices.
By following the TensorFlow for Poets Code Labs, participants gain a comprehensive understanding of image classification using TensorFlow and learn how to optimize their models for deployment on mobile devices. This knowledge can be applied to various domains, such as object recognition, visual search, and augmented reality.
