80/20 Study Guide - Key Concepts
Neural Networks
Neural networks are computational models inspired by the human brain, consisting of layers of interconnected nodes (neurons) that process data to make predictions or decisions.
The 20% You Need to Know:
- Neural networks consist of input, hidden, and output layers.
- Activation functions like ReLU introduce non-linearity.
- Training involves forward propagation, loss calculation, and backpropagation.
- Optimizers like Adam adjust weights to minimize loss.
Why It Matters:
Neural networks are the backbone of deep learning, enabling complex tasks like image recognition, natural language processing, and more.
Simple Takeaway:
Neural networks learn patterns from data to make predictions.
TensorFlow Basics
TensorFlow is an open-source library developed by Google for building and training machine learning models, particularly neural networks.
The 20% You Need to Know:
- TensorFlow uses tensors (multi-dimensional arrays) as its core data structure.
- It provides high-level APIs like Keras for quick model building.
- Graph execution allows for efficient computation.
- TensorFlow supports GPU/TPU acceleration for faster training.
Why It Matters:
TensorFlow simplifies the process of building and deploying deep learning models, making it accessible to both beginners and experts.
Simple Takeaway:
TensorFlow is a powerful tool for creating and training AI models.
Model Training
Model training is the process of adjusting a neural network's weights to minimize the difference between its predictions and the actual data.
The 20% You Need to Know:
- Training requires labeled data (input-output pairs).
- Loss functions measure prediction errors.
- Backpropagation updates weights using gradients.
- Epochs define the number of times the model sees the entire dataset.
Why It Matters:
Effective training ensures that models generalize well to new, unseen data, making them reliable for real-world applications.
Simple Takeaway:
Training teaches the model to make accurate predictions.
