What is an expert system? What are the characteristics of an expert system?

An expert system is an Artificial Intelligence program that has expert-level knowledge about a specific area and how to utilize its information to react appropriately. These systems have the expertise to substitute a human expert. Their characteristics include:

High performance
Adequate response time
Reliability
Understandability

Would you use batch normalization? If so, can you explain why?

The idea here is to standardize the data before sending it to another layer. This approach helps reduce the impact of previous layers by keeping the mean and variance constant. It also makes the layers independent of each other to achieve rapid convergence. For example, when we normalize features from 0 to 1 or from 1 to 100, it helps accelerate the learning cycle.

What is a partial-order planning?

A problem has to be solved in a sequential approach to attain the goal. The partial-order plan specifies all actions that need to be undertaken but specifies an order of the actions only when required.

What is a recommendation system?

A recommendation system is an information filtering system that is used to predict user preference based on choice patterns followed by the user while browsing/using the system.

What does Partial order or planning involve?

In partial order planning , rather than searching over possible situation it involves searching over the space of possible plans. The idea is to construct a plan piece by piece.

Where do you usually source your data sets?

If you talk about AI projects that you’ve worked on in your free time, the interviewer will probably ask where you sourced your data sets. If you’re genuinely passionate about the field, you would have worked on enough projects to know where you can find free data sets.

What’s TensorFlow?

TensorFlow is an open-source framework dedicated to ML. It’s a comprehensive and highly adaptable ecosystem of libraries, tools, and community resources that help developers build and deploy ML-powered applications. Both AlphaGo and Google Cloud Vision were built on the Tensorflow platform.

Which is not commonly used programming language for AI?

Perl language is not commonly used programming language for AI

Which search algorithm will use a limited amount of memory in online search?

RBFE and SMA* will solve any kind of problem that A* can’t by using a limited amount of memory.
