Q2. What is a Central Limit Theorem?
Ans. 
Central Limit Theorem states that the sampling distribution of the mean of any independent, random variable will be normal or nearly normal.
• The theorem applies to large sample sizes.

• It is a fundamental concept in statistics.

• It is used to estimate population parameters from sample statistics.

• It is important in hypothesis testing and confidence intervals.

• Example: If we take a large number of samples of the same size from...read more

Q3. Can you explain gradient descent?
Ans. 
Gradient descent is an iterative optimization algorithm used to minimize a cost function by adjusting model parameters.
• Gradient descent is used in machine learning to optimize models.

• It works by iteratively adjusting model parameters to minimize a cost function.

• The algorithm calculates the gradient of the cost function and moves in the direction of steepest descent.

• There are different variants of gradient descent, such...read more

Add your answer
Q4. How is object detection done using CNN?
Ans. 
Object detection using CNN involves training a neural network to identify and locate objects within an image.
• CNNs use convolutional layers to extract features from images

• These features are then passed through fully connected layers to classify and locate objects

• Common architectures for object detection include YOLO, SSD, and Faster R-CNN
