# tensorflow-trainer

## Overview

TensorFlow/Keras model training skill with callbacks, distributed strategies, TensorBoard integration, and production-ready model export capabilities.

## Capabilities

- Keras model training with callbacks
- Custom training loops with tf.GradientTape
- Distribution strategy configuration (MirroredStrategy, MultiWorkerMirroredStrategy, TPUStrategy)
- TensorBoard logging and visualization
- SavedModel export for TF Serving
- TFLite conversion for edge deployment
- Mixed precision training

## Target Processes

- Model Training Pipeline with Experiment Tracking
- Distributed Training Orchestration
- Model Deployment Pipeline

## Tools and Libraries

- TensorFlow
- Keras
- TensorBoard
- TensorFlow Serving
- TensorFlow Lite
