Study Notes
Gradient Descent Overview
- Gradient descent is an optimization algorithm used to minimize the loss function in neural networks.
- The primary goal is to find the optimal weights and biases that minimize the difference between predicted and actual values in deep learning models.
Steps in Gradient Descent
- Two iterative steps are performed by gradient descent:
- Calculate Gradient: Determine the gradient of the loss function with respect to model parameters (weights and biases), indicating the direction of steepest ascent.
- Update Parameters: Adjust the parameters in the opposite direction of the gradient to reduce the loss function, using a learning rate to control the size of the update.
Goal of Gradient Descent
- The ultimate objective is to minimize the loss function, thus increasing the predictive accuracy of the model over time.
Algorithm Behind Training
- The fundamental algorithm used in training deep learning models is based on gradient descent, leveraging its iterative approach to optimize model performance.
