What’s an eigenvalue? What about an eigenvector?

The directions along which a particular linear transformation compresses, flips, or stretches is called eigenvalue. Eigenvectors are used to understand these linear transformations.

For example, to make better sense of the covariance of the covariance matrix, the eigenvector will help identify the direction in which the covariances are going. The eigenvalues will express the importance of each feature.

Eigenvalues and eigenvectors are both critical to computer vision and ML applications. The most popular of these is known as principal component analysis for dimensionality reduction (e.g., eigenfaces for face recognition).

What is agent in artificial intelligence?

Anything perceives its environment by sensors and acts upon an environment by effectors are known as Agent. Agent includes Robots, Programs, and Humans etc.

How is Google training data for self-driving cars?

If you’re interested and heavily involved within this space, this question should be a no-brainer. If you know the answer, it’ll demonstrate your knowledge about a variety of ML methods and how ML is applied to autonomous vehicles. But even if you don’t know the answer, take a stab at it as it will show your creativity and inventive nature.

Google has been using reCAPTCHA to source labeled data on storefronts and traffic signs for many years now. The company also has been using training data collected by Sebastian Thrun, CEO of the Kitty Hawk Corporation and the co-founder (and former CEO) of Udacity.

Such information, although it might not seem significant, will show a potential employer that you’re interested and excited about this field.

What’s a Turing test?

The Turing test, named after Alan Turing, is a method of testing a machine’s human-level intelligence. For example, in a human-versus-machine scenario, a judge will be tasked with identifying which terminal was occupied by a human and which was occupied by a computer based on individual performance.

Whenever a computer can pass off as a human, it’s deemed intelligent. The game has since evolved, but the premise remains the same.

Define LSTM.

Long short-term memory (LSTM) is explicitly designed to address the long-term dependency problem, by maintaining a state of what to remember and what to forget.

What are the various areas where AI (Artificial Intelligence) can be used?

Artificial Intelligence can be used in many areas like Computing, Speech recognition, Bio-informatics, Humanoid robot, Computer software, Space and Aeronautics’s etc.

For online search in ‘Artificial Intelligence’ which search agent operates by interleaving computation and action?

In online search, it will first take action and then observes the environment.
