Q1. What is Stochastic Gradient Descend?
Ans. 
Stochastic Gradient Descent is an optimization algorithm used to minimize the cost function in machine learning by updating parameters iteratively.
• SGD is a variant of Gradient Descent that updates the model's parameters using a single training example at a time.

• It is computationally efficient and is commonly used in large-scale machine learning tasks.

• SGD is suitable for online learning and can handle large datasets eff...read more

Q2. How to improve SGD?
Ans. 
To improve SGD, consider adjusting learning rate, using momentum, implementing learning rate schedules, and adding regularization techniques.
• Adjust learning rate: Experiment with different learning rates to find the optimal value for faster convergence.

• Use momentum: Incorporate momentum to accelerate SGD in the relevant direction and dampen oscillations.

• Implement learning rate schedules: Decay the learning rate over ti...read more
