A+
◉ The time series is shifted back by N observations.. Answer: What
happens when a time series is lagged for N observations?
◉ Querying. Answer: user knows what he or she wants and can
describe it
◉ Navigation. Answer: user knows what he or she wants and cannot
describe it or locate it
◉ Exploration. Answer: user doesn't know what he or she wants.
Wants to acquire new knowledge and reveal new facts
◉ Analysis, Comparison, Aggregation, Transformation, Visualization.
Answer: What are the five types of exploration tools?
◉ Volume, velocity, variety. Answer: 3Vs
◉ HMLE. Answer: High dimensional (lots of different things we want
to explore)
,Multi modal (different ways needed to visualize it)
inter-Linked (data is linked, sometimes null, sometimes implicit)
Evolving (underlying patterns change)
◉ INS. Answer: Imprecision
Noise
Sparsity
◉ Cognition. Answer: The mental action of efficiently and effectively
being able to process information into thoughts, knowledge, and
insights
◉ Visualization. Answer: Graphically representing data to assist the
processing of information into knowledge, insights, and thoughts.
Uses exploratory data analysis to find trends and patterns in
datasets.
◉ Main components of a sequence. Answer: starting point, ending
point, length
