text and video analysis

text analysis and video analysis

descriptive analysis

preliminary data processing stage, identifies patterns, and answers who, what, where, when, and to what extent

predictive analytics

techniques to analyze current data to identify future probabilities and trends to make predictions about the future

optimization

allocates scarce resources to minimize costs or maximize profits

simulation

emulates the dynamic responses of a real-world system to various inputs

text and video analysis

glean insights and data relevant to decision making

visual analytics

word cloud - words grouped together based on frequency of their occurrence

regression analysis

determines the relationship between a dependent variable and one or more independent variables to produce a regression equation

time-series analysis

analyzing data using statistical methods to extract meaningful statistics and characteristics

data mining

explores large amount of data for hidden patterns to predict future trends and behaviors to use in decision making

three types of data mining techniques

association analysis, neural computing, and case-based reasoning

genetic algorithm

natural selection-like process to find approximate solutions to optimize and search problems

linear programming

calculation based on the value of a set of decision variables to find the optimum value of a linear expression

scenario

predicts future values based on certain potential events

monte carlo simulation

spectrum of thousands of possible outcomes considering the many variables involved with the range of potential values for each variable

text analysis

process for extracting value from large quantities of unstructured text data

video analysis

process of obtaining information or insights from video footage

input/output devices

allows interaction with a computer system

optical data readers

special scanning device to scan documents using optical mark recognition (OMR) and optical character recognition (OCR)

bar-code scanners

laser scanners reads a label, may be stationary or handheld

radio frequency identification (RFID) devices

microchip with an antenna broadcasts its unique identifier and location, transmits data to a tag, tag is read by the device and processed

pen input devices

touches screen and activates commands with a tool

touch screen

activate programs or trigger other types of action with skin contact

display screens

graphics card translates binary data from CPU into an image, GPU renders images on the screen

printers and plotters

lasers and inkjets

3D printers

create objects using strands of a plastic filament or synthetic powder
