TensorFlow Lite conversion - Model Pipeline Trace

Model Pipeline - TensorFlow Lite conversion

This pipeline shows how a TensorFlow model is converted into a smaller, faster TensorFlow Lite model for use on mobile or embedded devices.

Data Flow - 3 Stages

1Original TensorFlow Model

1000 rows x 784 columns→Train a neural network on input data→1000 rows x 10 columns

Input: 784 pixel values (28x28 image) per image; Output: 10 class probabilities

↓

2Model Saved

Model weights and architecture→Save the trained TensorFlow model to disk→SavedModel format files

Saved model folder with variables and assets

↓

3TensorFlow Lite Conversion

SavedModel format files→Convert TensorFlow model to TensorFlow Lite flatbuffer format→TensorFlow Lite model (.tflite file)

A small .tflite file ready for mobile deployment

Training Trace - Epoch by Epoch

Epoch 1: ************ (loss=1.2)
Epoch 2: ******** (loss=0.8)
Epoch 3: ***** (loss=0.5)
Epoch 4: *** (loss=0.35)
Epoch 5: ** (loss=0.30)

Epoch	Loss ↓	Accuracy ↑	Observation
1	1.2	0.55	Model starts learning basic patterns
2	0.8	0.72	Loss decreases, accuracy improves
3	0.5	0.85	Model converging well
4	0.35	0.90	Good accuracy, loss low
5	0.30	0.92	Training stabilizes
