10 Exclusive Data Science Techniques and features

10 Data Science Techniques and Features

Data science has grown tremendously in popularity in recent years, with companies like Amazon, Facebook, Google, and more building out massive internal teams dedicated to analyzing their data using all sorts of statistical techniques, machine learning methods, and more. But how much do you know about these advanced data science techniques? What are the most popular ones being used today? And what can you learn to help you become a better data scientist in your own field? In this post we’ll look at 10 of the most common data science techniques and features that data scientists use every day.

Data science


1) Data Wrangling

Data wrangling is a data science technique used to prepare and cleanse data so that it’s ready for analysis. Data-wrangling scripts are often written using languages like Python or R, which let you manipulate and transform your data into a consistent format in order to make it easier to work with. While many people think of data wrangling as a way to clean up dirty or messy datasets, you can also use these techniques to test assumptions about how certain variables relate. 

2) Visualization Tools

Creating beautiful charts and graphs is one of our favorite things about data science. Whether it’s with Python libraries like matplotlib or Seaborn, R’s ggplot2, Plotly.js in JavaScript, Processing.js or just a tool that spits out HTML, there are many different options for creating visualizations of your data—and they all have distinct advantages and disadvantages.

3) Data Preparation

Preparing data for analysis is a crucial first step in any data science project. Data has to be checked for accuracy, cleaned up, organized, standardized, and categorized. This process should not be skipped over—it’s imperative that data is prepared correctly if you’re going to get accurate results from your model.

4) Model Types

There are two main types of models in data science: predictive, which makes predictions about future outcomes, and descriptive, which provides insights into present situations. As you dig deeper into data science, you’ll find that there are also many different subtypes within these categories. A helpful way to understand these distinctions is by thinking about their end goals. Predictive models aim to make decisions or provide guidance; descriptive models aim to simply describe or understand a current situation.

5) Big Data Capabilities

Data science


Big data is all about collecting, analyzing, modeling, visualizing, interpreting and communicating business information. Data science is essentially a combination of Big Data technology capabilities that includes predictive analytics, machine learning techniques (supervised or unsupervised), natural language processing techniques (NLP) with powerful analytical tools to understand human behavior. 

6) Machine Learning Capabilities

A data scientist can use machine learning to identify connections between variables in your database and then generate predictions based on those findings. In some cases, a data scientist can feed all of your historical data into an algorithm, analyze it, identify patterns, and create a model to help with predictions. In other instances—where more precision is needed—you may need to gather additional input from customers or subjects.

7) Programming Languages

Data science

Choosing a programming language for data science is important, but it’s a decision that will be influenced by more than just technology. Be sure to choose one that you are familiar with, because learning a new language can be challenging, especially when doing so while immersed in complex data sets. Take into account what you have experience with, and if there is no obvious choice based on your background, look at factors like hiring availability for people with similar skillsets.

8) Real-Time Analytics (Streaming Data, ETL, etc.)

Data streaming refers to receiving real-time data from a source, processing it in real time, and applying business logic to it. Streaming analytics allow organizations to monitor live changes in data streams or activity feeds in order to analyze user behavior or business activity. For example, many websites use streaming analytics on their activity feeds so that administrators can monitor what users are doing while they’re online.

9) Scalability with Cloud Computing

In recent years, cloud computing has become very popular. Companies like Google and Facebook use it for processing vast amounts of data, but it is also useful for smaller-scale projects. For example, even a simple data science project can be done using cloud computing. Public cloud services are cheaper than in-house software as you need to only pay for what you use; this makes it an excellent choice for startups or small businesses with tight budgets.

10) Security and Reliability


Security has always been a major concern in big data. It is crucial to identify whether your data might have potential security issues. Considering it is not possible to completely shield sensitive information, businesses should focus on securing it with strong encryption methods. Additionally, they should ensure their systems are protected against cyber threats such as hacking and DDoS attacks. All it takes is one security breach for a business to lose thousands of dollars in loss of reputation, etc., not to mention regulatory fines.
