Ans. Script-bot
Script bots are easy to make
Script bots work around a script which is
programmed in them
Mostly they are free and are easy to integrate to a messaging platform
Smart-bots are flexible and powerful
Smart bots work on bigger databases and other
resources directly
Smart bots learn with more data

13. What do you mean by Evaluation of an Al model? Also explain the concept of 2
overfitting with respect to Al model Evaluation.
Ans. Evaluation is the process of understanding the reliability of any AI model, based on
outputs by feeding test dataset into the model and comparing with actual answers.
There can be different Evaluation techniques, depending of the type and purpose of
the model.
 our model will simply remember the whole training set, and will therefore always
predict the correct label for any point in the training set. This is known as overfitting.
