Step-by-Step Guide: Building a Simple Image Classifier

This guide demonstrates how to build a simple image classifier using TensorFlow and Keras.

1. Install Required Libraries:

pip install tensorflow keras
Enter fullscreen mode Exit fullscreen mode

2. Import Libraries:

import tensorflow as tf
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Conv2D, MaxPooling2D, Flatten, Dense
from tensorflow.keras.preprocessing.image import ImageDataGenerator
Enter fullscreen mode Exit fullscreen mode

3. Prepare the Data:

  • Download a dataset of images (e.g., CIFAR-10).
  • Split the dataset into training and validation sets.

4. Create the Model:

model = Sequential([
    Conv2D(32, (3, 3), activation='relu', input_shape=(32, 32, 3)),
    MaxPooling2D((2, 2)),
    Conv2D(64, (3, 3), activation='relu'),
    MaxPooling2D((2, 2)),
    Flatten(),
    Dense(10, activation='softmax')
])
Enter fullscreen mode Exit fullscreen mode

5. Compile the Model:

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

6. Train the Model:

model.fit(train_generator, epochs=10, validation_data=validation_generator)
Enter fullscreen mode Exit fullscreen mode

7. Evaluate the Model:

loss, accuracy = model.evaluate(test_generator)
print("Loss:", loss)
print("Accuracy:", accuracy)
Enter fullscreen mode Exit fullscreen mode

Challenges and Limitations

  • Data Bias: ML models can inherit biases present in the training data, leading to unfair or discriminatory outcomes.
