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

The exam consists of seven sections, and the cutoff score is quite high; it is essential to complete the exam thoroughly.
The latest news I heard regarding technology is the release of the new iPhone 13 with improved camera features.
Apple recently announced the release of the iPhone 13 series with upgraded camera capabilities.
The new iPhone 13 models come with improved low-light performance and cinematic mode for videos.
Apple also introduced the A15 Bionic chip for enhanced performance and battery life.

An aptitude test evaluates an individual's potential to excel in a specific area by assessing their strengths and weaknesses in particular abilities.
An assessment that measures an individual's inherent abilities and potential for success in a specific activity.
A coding test is a programming assessment designed to evaluate a candidate's coding skills. It is a standard component of the technical hiring process for software developers and programmers.
Assessment that evaluates a candidate's coding skills
Group discussion (GD) topics for interviews may cover areas such as business, social issues, and current affairs. GDs serve to evaluate a candidate's communication, leadership, and teamwork abilities.
Discussion assignments are prompts that your teacher may assign to you. By participating in these discussions, you can reflect on your learning, share ideas and opinions, or ask and answer questions. Discussions may require you to respond to individual questions or provide multiple responses to an ongoing conversation.

A sequence was provided: 4181, 2684, 1597, 987, 610.
first 2 are given and write code for other value calculation using java 8
The second question required writing a reverse of a palindrome using both Java 8 streams. I was able to successfully write both and clear the first round.
Java 17 introduces sealed classes to restrict inheritance and improve code maintainability.
Sealed classes are declared using the 'sealed' keyword followed by the permitted subclasses.
Subclasses of a sealed class must be either final or sealed themselves.
Errors may occur when trying to extend a sealed class with a non-permitted subclass.
Implementation of 'notify me if item is back in stock' feature in an ecommerce application
