Chapter 11: Improving Decision Making and Managing AI

Question 1

What are unstructured decisions?

Answer 1

decision maker uses judgment, evaluation and insight in DM. Decision is new, important and not routine. There is no procedure and these decisions are reserved for top management

Question 2

What are semistructured decisions?

Answer 2

Only a part of the problems has a clear answer and accepted procedure. The remainder uses judgment and insight. REserved for middle management

Question 3

What are structured decisions?

Answer 3

There are repetitive and routine decisions involving procedures to handle them. These decisions are for operational management

Question 4

What are the four steps in decision making?

Answer 4

1. Identify the problem
2. Identify the alternatives
3. Choose best option
4. Implement

Question 5

What are the elements of a business intelligence (BI) environment?

Answer 5

1. Data from business environment
2. Business Intelligence infrastructure
3. BI toolset
4. Managerial user and methods
5. Delivery platform - MIS,Decision & Executive support systems)
6. User Interface

Question 6

What is analytical BI functionality?

Answer 6

This means that the production and parameterized reports, dasbods, ad hoc query/search creation, drill down & forecasts, scenarios and models

Question 7

what is predictive analysis?

Answer 7

This uses stats, datamining, historical data and assumptions to predict future trends and patterns

Question 7

What is location analytics?

Answer 7

Gaining business insights from the location where data is gained

Question 7

What is machine learning?

Answer 7

This begins with very large datasets to find patterns and relationships in data

Question 8

What is supervised learning?

Answer 8

System is trained through specific examples identified by humans.

Question 8

What is operational intelligence?

Answer 8

This means monitoring operational decisions

Question 9

What are geographic information systems?

Answer 9

these systems provide tools to visualize problems benefitting from mapping. Ties location data to a map

Question 10

What is the balanced scorecard method?

Answer 10

This is an operationalization of the strategic objectives by measuring measurable objectives in financial, business process, customer and learning and growth. Performance measures are called Key Performance Indicators (KPIs)

Question 10

Wat is the inference engine?

Answer 10

Strategy to search through knowledge base

Question 10

What are Expert systems?

Answer 10

These systems capture knowledge of experts and represents this knowledge as sets of rules, converted into a computer code to help users through decision making process.

These rules are called the knowledge base

Question 11

What are deep learning networks?

Answer 11

These are more complex networks with layers transforming data to produce target output.

Question 12

What is natural language processing?

Answer 12

Computer analyzes natural language

Question 12

What is unsupervised learning?

Answer 12

system is asked to process database and report patterns it found

Question 13

What are the limitations of machine learning and neural networks?

Answer 13

1. Requires very large datasets to identify patterns, which is not always realistic in real life
2. No explanation of why machine learning chose what it did
3. No ethical consideration
4. Many problems are not suitable for yes/no decisions

Question 14

What are genetic algorithms?

Answer 14

This finds solutions by examining large number of alternatives to a problem. it us used for problems involving thousands of variables.

Question 15

What are computer vision systems?

Answer 15

These systems emulate human visual systems to view and extract information from real-world images

Question 16

What are robotics?

Answer 16

Robotics deal with design, construction, and use of movable machines instead of humans. These robots are programmed to perform certain activities

Question 17

What are intelligent agents?

Answer 17

These are software programs carrying out specific tasks for individual users, processes or applications in the background withoug human intervention
