Those who are tight on a budget can also opt for the free certification course . Many can learn new techniques without having to spend anything.
Role of Data Scientist
A Data Analyst explains business analytics and intelligence course, but a Data Scientist does the exploratory analysis to discover insights from it. A Data Scientist uses various advanced machine learning algorithms to identify the occurrence of a particular event and predict the future.
A Data Scientist will look at the data from different angles so that one can easily make decisions and predictions by using predictive causal analytics, prescriptive analytics and machine learning.
Application of data:
·A simple but by far application is in Google's self-driving car. It works after data is gathered by vehicles. Algorithms are run on the data to bring intelligence so that the car can decide when to turn when to slow down, speed up, and where to go.
·Data helps in making a prediction. For instance, machine learning algorithms are the best bet if there are any transactional data of a finance company and the need to build a model to determine the future trend. It is also referred to as
supervised learning as the data is already there to train the machines.
Data can help in pattern discovery. For example, if there are parameters on which one can make predictions, then the hidden patterns within the dataset should be identified.
Data can be analysed with the BI tools after taking it from different sources like the financial logs, text files, multimedia forms, sensors, and instruments.
Data Science understands the precise requirements of customers. It is taken from the existing data like the customer’s past browsing history, purchase history, age and income.
