Some OpenCV problems
Activation functions are used to introduce non-linearity into neural networks, allowing them to learn complex patterns and relationships.
Activation functions help neural networks to learn complex patterns and relationships by introducing non-linearity.
They help in controlling the output of a neuron, ensuring that it falls within a desired range.
Common activation functions include ReLU, Sigmoid, Tanh, and Leaky ReLU.

Learning rate is a hyperparameter that controls how much we are adjusting the weights of our network with respect to the loss gradient.
Learning rate determines the size of the steps taken during optimization.
A high learning rate can cause the model to overshoot the optimal weights, while a low learning rate can result in slow convergence.
Common learning rate values are 0.1, 0.01, 0.001, etc.
Learning rate can be adjuste...
CNN is used for image recognition while RNN is used for sequence data like text or speech.
CNN is Convolutional Neural Network, used for image recognition tasks.
RNN is Recurrent Neural Network, used for sequence data like text or speech.
CNN has convolutional layers for feature extraction, while RNN has recurrent connections for sequential data processing.
CNN is good at capturing spatial dependencies in data, while RNN i...
Yes, Logloss function is differentiable.
Logloss function is differentiable as it is a smooth and continuous function.
The derivative of Logloss function can be calculated using calculus.
Differentiability is important for optimization algorithms like gradient descent to converge smoothly.
Example: The derivative of Logloss function for binary classification is (predicted probability - actual label).
I applied via LinkedIn and was interviewed in Oct 2022. There were 4 interview rounds.
Implement a model improvement using a C++ API of Pytorch.
To rotate an image in Python, use the Pillow library's rotate() method.
Import the Image module from the Pillow library
Open the image using the open() method
Use the rotate() method to rotate the image by the desired angle
Save the rotated image using the save() method
Breadth first search problem
BFS is a graph traversal algorithm that visits all the vertices of a graph in breadth-first order
It uses a queue to keep track of the nodes to be visited next
BFS can be used to find the shortest path between two nodes in an unweighted graph

I applied via Referral and was interviewed in May 2021. There were 3 interview rounds.
Append and Merge are two methods used to combine data from multiple sources into a single dataset.
Append adds new rows to an existing dataset.
Merge combines two or more datasets based on a common column or key.
Append is useful when adding new data to an existing dataset, while Merge is useful for combining datasets with related information.
Example: Appending new sales data to an existing sales dataset.
Example: Merging ...
