Machine learning perfects the decision model presented under predictive analytics by matching the likelihood of an event happening to what actually happened at a predicted time. The Data Science Major will equip students to draw sound conclusions from data in context, using knowledge of statistical inference, computational processes, data management strategies, domain knowledge, and theory. Students will learn to carry out analyses of data through the full cycle of the investigative process in scientific and practical contexts. Students will gain an understanding of the human and ethical implications of data analytics and integrate that knowledge in designing and carrying out their work. On the other hand, Data Scientist not only does the exploratory analysis to discover insights from it, but also uses various advanced machine learning algorithms to identify the occurrence of a particular event in the future. A Data Scientist will look at the data from many angles, sometimes angles not known earlier.

The solution employs deep analytics and machine learning to gather real-time insights into viewer behavior.

In the decision tree, we start from the root of the tree and compare the values of the root attribute with record attribute. On the basis of this comparison, we follow the branch as per the value and then move to the next node. We continue comparing these values until we reach the leaf node with predicated class value. In the decision tree algorithm, we can solve the problem, by using tree representation in which, each node represents a feature, each branch represents a decision, and each leaf represents the outcome. Understanding the data to make better decisions and finding the final result. UC Berkeley has one of the strongest and most generous financial aid programs in the country…

Machine learning tools are not completely accurate, and some uncertainty or bias can exist as a result. Biases are imbalances in the training data or prediction behavior of the model across different groups, such as age or income bracket. For instance, if the tool is trained primarily on data from middle-aged individuals, it may be less accurate when making predictions involving younger and older people.
