Blue Yonder Interview Questions, Process, and Tips

Q1. Explain back propagation?
Ans. 
Back propagation is a technique used in neural networks to update the weights of the network by calculating the gradient of the loss function with respect to the weights.
• Back propagation involves calculating the error at the output layer and then propagating it back through the network to update the weights using gradient descent.

• It uses the chain rule of calculus to calculate the gradient of the loss function with res...read more

Q2. Explain batch normalization?
Ans. 
Batch normalization is a technique used in machine learning to improve the training of deep neural networks by normalizing the input of each layer.
• Batch normalization normalizes the input of each layer by adjusting and scaling the activations.

• It helps in reducing internal covariate shift, which leads to faster convergence during training.

• Batch normalization also acts as a regularizer, reducing the need for other regula...read more

Q1. Explain transformer architechure?
Ans. 
Transformer architecture is a type of deep learning model that uses self-attention mechanism to process sequential data.
• Utilizes self-attention mechanism to weigh the importance of different input elements

• Consists of encoder and decoder layers for processing input and generating output

• Introduced in the paper 'Attention is All You Need' by Vaswani et al. in 2017

Q2. How back propagation overtime works?
Ans. 
Back propagation over time is a method used in recurrent neural networks to update weights by propagating errors backwards through time.
• Back propagation through time (BPTT) is an extension of the backpropagation algorithm for recurrent neural networks.

• It involves unfolding the network over time and calculating gradients for each time step.

• The gradients are then used to update the weights of the network to minimize the ...read more

Q1. Explain microservices architecture.
Ans. 
Microservices architecture is an architectural style that structures an application as a collection of loosely coupled services.
• Each service is self-contained and can be developed, deployed, and scaled independently.

• Services communicate with each other over lightweight protocols like HTTP or messaging queues.

• Microservices allow for better scalability, flexibility, and resilience compared to monolithic architectures.

• Exa...read more
