For each course, both foundation and advanced, you find at
http://datascience.berkeley.edu/academics/curriculum/ briefly state (in 2 to 3 lines) what
they offer? Based on the given course description as well as from the video. The purpose
of this question is to understand the different streams available in Data Science.
The students who have fared well in OOP will get 12 units of coursework in the foundation
courses. The students who are not good in object oriented programming are assigned with 15
coursework.
In the foundation courses include various subjects like applied machine learning, statistics of
data science, data analysis, sorted data engineering.
The advanced courses have several subjects like data visualizations, machine learning at
scale, scaling up big data, casually and experiments, human values and deep learning.
Exercise 2: Characteristics of Big Data (2 marks)
Read the following research paper from IEEE Xplore Digital Library
Ali-ud-din Khan, M.; Uddin, M.F.; Gupta, N., "Seven V's of Big Data understanding Big
Data to extract value," American Society for Engineering Education (ASEE Zone 1), 2014
Zone 1 Conference of the , pp.1,5, 3-5 April 2014
and answer the following questions:
Summarise the motivation of the author (in one paragraph)
The author has tried to explain that big data is the only solution that can solve a number of

What are the 7 v’s mentioned in the paper? Briefly describe each V in one paragraph.
The 7Vs of the paper are volume, velocity, value, validity, veracity, volatility and variety. The
volume shows that creation of big data from numerous sources such as research studies,
images, video, text and audio. It can be also taken from government documents, telemetry,
web pages and social media which explains the volatility aspect. The velocity aspect stats
that the system that is handling the big data should have infrastructures that are capable of
processing the big data at high speed. Value and veracity comes from the different use f
clouds and browsers for the big data.
