Name the phase which comes before data exploration. In this phase data needed for an AI project is collected through various sources and generally in different formats.

• Modelling

• Problem Scoping

• Evaluation

• Data Acquisition

In which phase of an AI project life cycle, the right algorithms are selected and an AI model for working with the data is built. The selection of the model depends upon the data being used and outcome desired.

• Modelling

• Problem Scoping

• Data Exploration

• None of the above.

Which of the following tool is used in problem scoping phase of an AI project life cycle?

• Classification

• Clustering

• 4Ws problem Canvas

• None of the above.

Which are the correct options for rule based AI models?

• Machine Learning is static as no change in original dataset can be made by machine itself.

• It is used to develop simple AI projects.

• It is used to develop complex AI projects.

• Rules are defined by developer.

4 Ws Problem Canvas asks four questions. These are :

• When

• What

• Which

• Where

An AI model is a program or algorithm that utilizes a set of data that enables it to recognize found data patterns. This allows it to reach a conclusion or make a prediction when provided with sufficient information. Types of AI models are :

• 4Ws Problem Canvas

• Classification

• Regression

• Clustering

Which of the following statements are true ?

• Dataset used in evaluation phase for ML model is called testing dataset. It is the final step to verify ML Model's functionality.

• Dataset used in modelling phase to train the ML model is called training dataset. It consists of 70% of dataset set aside in Data acquisition phase.

• Dataset used in modelling phase to check the output of developed ML model is called validation dataset. It usually consists of 30% of dataset available in modelling phase.

• Generally during data acquisition phase, 80% dataset is reserved for training plus validating ML model and just 20% for Evaluation phase.

• Dataset used in in evaluation phase is new dataset which has never been seen by ML model.

An AI project life cycle has

• four phases.

• five phases.

• six phases

• none of the above.

In Data Acquisition phase data is collected in various formats from data sources. Which of the following statements are correct?

• Video dataset can be collected in mp3 as well as mp4 format.

• Image dataset is available in jpeg format.

• Datasets of DBMS are well handled by SQL.

• CSV is simplest data format to store data from files of simple word processors like notepad.

Data analysis is first step in which phase to find relationships between collected data .

• Data Exploration phase

• Data Acquisition phase

• Modelling phase

• Problem scoping phase
