Can only help you extract insights from data
- Cannot provide correlation related information
Slicing and dicing
Does not help you discover hidden predictive relationship in data
- Need data mining
, Tools that can help us analyze structured data and semi-structured data? - CORRECT
ANSWERS Text mining, web content mining, web usage mining
I work for amazon and I want a better understanding of customer web behavior. Which tool should I
use? - CORRECT ANSWERS Web usage mining

What is the purpose of decision support systems (DSS)? - CORRECT ANSWERS Provide support
for recurring semi-structured problems
What-if analysis:
==> Allow hypothetical changes to be added to the data associated with a problem and inform how
these changes influence the results Goal-seeking analysis:
==> Determine how input parameters need to be changed to achieve a desired end state
Examples of decision suport systems (DSS) - CORRECT ANSWERS Route planning tools that

The need to evaluate outputs and refine prompts until getting the desired results
The need to ensure that the outputs generated by GenAI is accurate and the use of GenAI is ethical
What is prompt engineering? - CORRECT ANSWERS The art and science of crafting commands
(prompts) to guide generative AI towards desired outputs.
Instruction-based prompts: Stating what you want AI to do, i.e., edit,
classify, generate, translate. Provide context. Use "shot" aka example.
Keyword-based prompts: Using specific terms to guide the generation of outputs
