Project Overview

This README documents my internship project focused on implementing an image classification model using Convolutional Neural Networks (CNNs) and Artificial Neural Networks (ANNs). The project leverages the CIFAR-10 dataset, a standard dataset for image recognition tasks, to classify images into one of ten categories.

Objective

The primary objective of this project was to:

Understand the basic and advanced concepts of Machine Learning (ML) and Deep Learning (DL).
Implement image classification models using CNN and ANN architectures.
Explore the performance of different models on real-world datasets.

Concepts Learned

Machine Learning Basics Supervised learning techniques. Data preprocessing, feature scaling, and dataset partitioning.

Deep Learning Fundamentals Understanding Neural Networks and their architectures. Backpropagation and optimization techniques like Adam and SGD. Overfitting, underfitting, and regularization methods

Dataset: CIFAR-10

**The CIFAR-10 dataset consists of:**

60,000 images categorized into 10 classes, each with 6,000 images.
Image dimensions of 32x32 pixels with RGB channels.
Classes include airplanes, cars, birds, cats, deer, dogs, frogs, horses, ships, and trucks.

Tools and Libraries

**Programming Language:** Python
**Libraries:** TensorFlow, NumPy, Matplotlib, Pillow, Streamlit

Implementation Highlights
