Study Notes
Artificial Intelligence and Deep Learning
- Artificial intelligence (AI) refers to the intelligence demonstrated by machines or software, aiming to replicate human-like cognitive functions such as learning and problem-solving.
- Deep learning is a subset of AI that utilizes neural networks with multiple layers to model complex data patterns.
Biological Neurons vs. Artificial Neurons
- Biological neurons operate through electrochemical signals, where a neuron activates and transmits signals to other neurons when specific criteria are met.
- The human brain comprises an estimated 100 billion interconnected neurons, facilitating complex decision-making processes.
McCulloch-Pitts Model of Neuron
- Developed in 1943 by Warren McCulloch and Walter Pitts, the model simulates biological neuron functions through binary inputs and outputs.
- An artificial neuron activates when a predetermined number of its inputs are active, primarily used in logical operations.
Perceptron (Single Layer Perceptron)
- Invented by Frank Rosenblatt in 1957, the perceptron is a simple model representing how the brain recognizes patterns.
- Unlike the McCulloch-Pitts model, perceptrons handle non-binary numerical inputs, associating weights with each input to produce binary outputs.
Weights and Biases
- Weights determine the significance of input signals, while biases account for additional factors that may affect the output.
- Adjustments to weights and biases during the learning process enable the perceptron to correctly classify input data.
Implementation and Applications
- The perceptron serves as a foundation for more complex neural network architectures, allowing for tasks such as image recognition and natural language processing.
- Understanding weights and biases is crucial for training AI models to minimize classification errors and improve accuracy.
Activation Functions
- Activation functions, like those used in perceptrons, define how inputs are transformed into outputs based on thresholds, impacting learning and performance in neural networks.
