Parabole Interview Questions and Answers

F1 Score is a measure of a test's accuracy that considers both the precision and recall of the test.

• F1 Score is the harmonic mean of precision and recall.

• It ranges from 0 to 1, where 1 is the best possible F1 Score.

• F1 Score is calculated using the formula: 2 * (precision * recall) / (precision + recall)

• It is commonly used in binary classification tasks.

Understanding how a trained neural network works involves grasping the concept of layers, weights, biases, and activation functions.

• Neural networks consist of layers of interconnected nodes that process input data.

• Weights and biases are adjusted during training to minimize error and improve accuracy.

• Activation functions introduce non-linearity to the network, allowing it to learn complex patterns.

• Understanding backprop...read more

Polling is a technique used in computer science to actively check the status of a resource or process at regular intervals.

• Polling involves continuously checking a resource or process for updates or changes.

• It is commonly used in networking to check for data transmission or reception.

• Polling can be inefficient as it requires constant checking, leading to wasted resources.

• An example of polling is a client repeatedly che...read more

Neural networks are used for complex pattern recognition and decision-making tasks.

• Neural networks can learn from data and make predictions without being explicitly programmed.

• They are used in image and speech recognition, natural language processing, and autonomous vehicles.

• Neural networks can handle non-linear relationships and complex patterns better than traditional algorithms.

• They are used in recommendation system...read more

Polling is a technique used to continuously check the status of a resource or process.

• Polling involves sending out periodic requests to check for updates or changes.

• It is commonly used in software development to monitor changes in data or resources.

• Polling can be synchronous or asynchronous, depending on the implementation.

• Examples of polling include checking for new emails in an inbox or updating a live chat feed.

Application deployment involves transferring code from development environment to production servers.

• Choose a deployment method (e.g. manual, automated, continuous deployment)

• Prepare the application for deployment by packaging it with necessary dependencies

• Select a deployment environment (e.g. cloud, on-premises)

• Transfer the packaged application to the deployment environment

• Configure the deployment environment (e.g. se...read more
