A beginner's guide to understanding the fundamentals of deep learning!
What is Deep Learning? 📚
Deep learning is a subset of machine learning that uses artificial neural networks (ANNs) to model complex patterns in data. Unlike traditional machine learning, it automatically learns features from raw data through multiple layers of processing.
Key Concepts 🔍
- Neurons: Basic units of neural networks that process information.
- Layers: Organized into input, hidden, and output layers.
- Activation Functions: Introduce non-linearity (e.g., ReLU, Sigmoid).
- Backpropagation: Technique to adjust weights using gradient descent.
- Overfitting: When a model learns training data too well, harming generalization.
Neural Network Structure 🧩
A simple neural network consists of:
- Input Layer: Receives raw data (e.g., images, text).
- Hidden Layers: Process data through weighted connections.
- Output Layer: Produces final results (e.g., classifications, predictions).
📌 Tip: Use activation functions to add complexity to your model!
Common Algorithms ⚙️
- Feedforward Neural Networks (FNNs): Basic structure for supervised learning.
- Convolutional Neural Networks (CNNs): Specialized for image processing.
