Data Science


What is Data Science?

Data Science is a blend of various tools, algorithms, and machine learning principles with the goal to discover hidden patterns from the raw data. As a discipline, Data science involves the collection and study of data – both structured and unstructured – to gain insights and information that can be used by organizations to create effective strategies. By collecting and analysing data and patterns over time data scientists can identify trends and make suggestions to stakeholders that will help them to find new market opportunities, enhance efficiency, reduce costs, and result in a competitive advantage in their industry.

The Pillars of Data Science Expertise

While data scientists often come from many different educational and work experience backgrounds, most should be strong in, or in an ideal case be experts in four fundamental areas. In no particular order of priority or importance, these are:

Communication (both written and verbal)
Mathematics (includes statistics and probability)
Computer science (e.g., software/data architecture and engineering)

In reality, people are often strong in one or two of these pillars, but usually not equally strong in all four.

Let’s take a different scenario to understand the role of Data Science in decision making. How about if your car had the intelligence to drive you home? The self-driving cars collect live data from sensors, including radars, cameras, and lasers to create a map of its surroundings. Based on this data, it takes decisions like when to speed up, when to speed down, when to overtake, where to take a turn – making use of advanced machine learning algorithms.

Let’s see how Data Science can be used in predictive analytics. Let’s take weather forecasting as an example. Data from ships, aircraft, radars, satellites can be collected and analysed to build models. These models will not only forecast the weather but also help in predicting the occurrence of any natural calamities. It will help you to take appropriate measures beforehand and save many precious lives.

Why Data Science?

Traditionally, the data that we had was mostly structured and small in size, which could be analysed by using simple BI tools. Unlike data in the traditional systems which was mostly structured, today most of the data is unstructured or semi-structured. The data trends show that by 2020, more than 80 % of the data will be unstructured..

This data is generated from different sources like financial logs, text files, multimedia forms, sensors, and instruments. Simple BI tools are not capable of processing this huge volume and variety of data. This is why we need more complex and advanced analytical tools and algorithms for processing, analysing and drawing meaningful insights out of it.

This is not the only reason why Data Science has become so popular. Let’s dig deeper and see how Data Science is being used in various domains.

How about if you could understand the precise requirements of your customers from the existing data like the customer’s past browsing history, purchase history, age and income. No doubt you had all this data earlier too, but now with the vast amount and variety of data, you can train models more effectively and recommend the product to your customers with more precision. Wouldn’t it be amazing as it will bring more business to your organization?

What Does a Data Scientist Do?

Before deciding where to get started, people should make sure they know what data scientists do. In short, they identify problems in existing data analytics and plan to dig deeper into more data to fix them. They do this throughout the entire lifecycle - from choosing the correct datasets to work with, collecting both structured and unstructured data from multiple sources, cleaning and validating datasets, creating and applying algorithms to mine the data, then analysing and interpreting it, and finally presenting the findings to key stakeholders.

Why Become
Data Scientist?

The job of Data scientist has become a new trend across the world, as the Data-driven decision making is increasing in popularity. Each and every company no matter how small or big they are, looking for employees who can understand and analyse the data.

It has already been declared as the hottest job, data scientist brings in skill sets and knowledge from various backgrounds such as mathematics, statistics, Analytics, modeling, and business acumen. These skills help them to identify patterns which can help the organization to recognize new market opportunities.
