What are some of the major problems in developing business analytic and AI systems? Select all that apply.

Since AI learns from the input data, data quality determines the quality of the applications. The learning mechanism and data accuracy are critical.

Because diverse types of data are constantly collected by these systems, clarity in how insights, conclusions, and recommendations are generated is lacking.

Special methodologies are needed to develop and implement business analytic and AI systems, due to the need for storing, cleaning, and curating large amounts of data requiring specialized machines.

Most of these systems are designed to be managed and updated in the cloud, making them easier targets to hackers and other potential threats.
