Welcome to the TensorFlow model definition tutorial! This guide will walk you through creating a basic neural network using TensorFlow, a popular machine learning framework. Let's get started!

Step-by-Step Guide

1. Install TensorFlow

Before you begin, make sure TensorFlow is installed in your environment:

pip install tensorflow

🧠 Tip: Use tensorflow for CPU/GPU support, or tensorflow-cpu if you don't need GPU acceleration.

2. Import Libraries

Start by importing TensorFlow and other necessary libraries:

import tensorflow as tf
from tensorflow.keras import layers, models

3. Define Model Architecture

Create a sequential model with dense layers:

model = models.Sequential([
    layers.Dense(64, activation='relu', input_shape=(784,)),
    layers.Dense(64, activation='relu'),
    layers.Dense(10, activation='softmax')
])

4. Compile the Model

Specify the optimizer, loss function, and metrics:

model.compile(optimizer='adam',
              loss='sparse_categorical_crossentropy',
              metrics=['accuracy'])

5. Train the Model

Use the fit method to train on your dataset:

model.fit(x_train, y_train, epochs=5)

📊 Check training progress with this visualization:

Save Your Model 📁

After training, save the model for later use:

model.save('my_model.h5')
