How can I become a Data Scientist?

Data Scientist

Data Science is one area with huge demand in the market owing to the rise in reliance on data-driven business processing in organizations. The field will witness a massive increase of up to 27.9% in employment by 2026.  An increase in demand also leads to excessive competition in the market. It is essential to have a good combination of skills, knowledge, and experience to become a successful data scientist. 

Skills Required to Become a Data Scientist

You need to have a versatile data science skillset to land a top gig as a data scientist. Programming is one such area wherein you shall have exceptional skills. You must master at least one programming language, such as R, Python, or others. These are important to perform data analytics effectively. R is a popular software environment. Many Machine Learning and Artificial Intelligence applications use R for data analytics and management. Python is an open-source programming language, and several data science applications are build using this language. successful data scientist.

As a Data Scientist, you will work around the datasets and carry out the operations, such as creation, gathering, storage, analysis, and management. Your organization may use MySQL, SQL Server, Oracle, NoSQL, or other database engines. You should have database skills to perform data operations on the datasets. 

Data Science and Machine Learning technologies go hand in hand. You need to have skills and knowledge in numerous ML techniques and models. These can include classification, clustering, support vector machines, neural networks, and others. 

Statistics and mathematical analysis are also important areas to master on for a data scientist. You will apply the concepts of statistics in data collection and implementation. Mathematical theories and concepts, such as differentiation, probability, infinite series, integration, etc., will also be directly applicable. You must have skills in these subjects to qualify for the role of a data scientist and succeed in showcasing exceptional performance. 

Business organizations now use Big Data frameworks for managing their datasets. Working knowledge on any Big Data tools, such as Hadoop, Tableau, Apache Spark, or others, will offer you an edge in the market. Your ability and skills in data visualization will also be significant in your role. 

Non-technical skills are equally important, such as communication, analytical abilities, risk management, decision-making, problem-solving, collaboration, and critical thinking. 

How to Become a Data Scientist? 

The skills and knowledge areas above are relevant for the position of data scientist. You can gain theoretical knowledge on programming languages, Statistics, Big Data, and other subjects from various courses available online. successful data scientist

However, you can be fit for the role of a data scientist only when you have working knowledge and experience in these subject areas. The best way to prepare yourself for the role of a data scientist is to work on a some real-world data science projects to gain hands-on experience.

You can take up beginner-level data science projects to understand your skills and the areas of improvement. For example, the Credit Card Fraud Detection project is one of the simple projects to begin with. You can build a simple predictive model for detecting credit card fraud and learn about some common machine learning algorithms like logistic regression, support vector machine, and random forest. You can then carry out cross-validation to enhance the quality of the outcomes. Also, a buffer section on outlier detection will assure high accuracy and reliability of the results. The project will offer you a chance to work on linear models, non-linear algorithms, and ensemble techniques.  

Another idea on beginner-level Data Science project is human activity recognition on Smartphone datasets. Python is a suitable programming language with multi-class classification as the Machine Learning technique.  The system will recognize human activity and classify it into a specific set of activities. You can cover activities like walking, sleeping, running, and sitting in your project. With this project, you will apply deep neural networks projects, normalize the datasets, and implement standard scaling. You will also carry out data cleaning and preparation,, which is the initial process in any Data Science project. 

Similarly, you can work on the music recommendation system. In this project, you will apply the prediction models to recommend music based on user preferences. The functionality is present in some of the popular music apps, such as Spotify and Amazon Music. You can also design a sales prediction model for any of the Supermarket stores. The data for such projects will be available on the e-commerce channels. You can also visit the offline stores and gather the data for your project. The combination of linear and non-linear algorithms will enhance your knowledge of ML and Data Science techniques. 

The majority of the organizations look for professionals with an amalgamation of technical and non-technical skills. In the non-technical skill set, communication, collaboration, team-building, and analytical skills are the primary characteristics. Working on the Data Science projects will enable you to acquire and improve your technical skills. You can work in small groups,, and it will lead to improvements in your communication and collaboration skills. While working on the projects, you will face numerous problems and challenges. You will get to analyze these problems and implement suitable resolutions to achieve the results. Problem-solving and analytical capabilities will improve in the process. 

You can also present all the data science projects you’ve worked on in the form of a portfolio to the recruiters during the selection process. The practical applications will significantly impact the selectors, and you will have the edge over the rest of the candidates. Data Science is a broad field with numerous concepts and technologies present under it. To be a successful Data Scientist, you shall continually look to acquire and improve your skills and knowledge. You shall look to diversify your skills with working knowledge and experience in data analytics, various machine learning technologies, Big Data tools, and AI concepts.For more information you can also read
