Gain a sound understanding of the crucial role of data in the development of artificial intelligence and cognitive applications, and how this importance has developed throughout the history of AI, though not always explicitly acknowledged. Learn how the quality and quantity of available data can make all the difference in pattern analysis and training. AI is experiencing a resurgence on the web, but the understanding that a good data corpus is the lifeblood of any AI is not widespread. Learn to avoid the enormous danger from AI doing more harm than good if problems of bias and statistical skew propagate from the data corpus. Gain an edge in developing successful AI applications by understanding the role of data in various AI techniques, and the characteristics of data sets that support those techniques.
