The main purpose of data science is to use various tools, machine learning principles, and algorithms in order to find hidden patterns in raw data. Data Science includes the preparation of data for processing and analysis, the performance of analysis, and the presentation of results to facilitate the decision-making process in organizations.
Preparation of data usually involves cleansing, aggregation, and manipulation so that it is ready for various types of processing and purposes. The analysis is driven by software that digs through data to find repetitive patterns and transform them into useful predictions.
In order to ensure that such predictions are valid, scientifically designed tests and experiments need to be performed on used AI models and algorithms.
The results of this analysis should be understandable for anyone, especially a person without ML and AI-related background. This is why they should be presented with visualization tools that enable effortless understanding and drawing conclusions.
Because of the above, professionals working as data scientists need to acquire computer science and data visualization skills. A good data scientist must be able to fulfill the following tasks:
- Apply mathematics, scientific methods, and statistics into everyday work
- Use a wide range of tools and technologies necessary for evaluation and preparation of data, such as Structured Query Language (SQL) or data integration methods
- Extract insights from data with the use of AI, ML, and deep learning
- Create models which automate data processing
- Talk about data in a way that clearly conveys the meaning of analysis results to stakeholders with different levels of technical knowledge and understanding
- Explain how information from data can be used to solve various business issues
In order to create ML and AI models, data scientists need to know how to code. Data scientists usually opt for programming languages that support or include statistical, machine learning, and graphic capabilities such as R or Python. They also should be proficient in using big data platforms such as Apache Spark. Additionally, to properly present analysis results, they may need knowledge of basic graphic tools to create business presentations and spreadsheet applications.
Use of data science
What is especially tempting about data science is the fact that there is an almost unlimited number of companies and industries which could benefit from its opportunities. Almost all business processes and most types of customer experience strategies can be improved with the use of data-driven optimization.
POSSIBLE USES OF DATA SCIENCE IN BUSINESS
- Decision making
As we have previously mentioned, the main purpose of data science is finding patterns and drawing conclusions from the organization’s data. Thanks to data science, answers to important business questions and solutions to problems occurring in the company can be easily found.
The popularity of ML models can be justified by the fact that data scientists adjust them according to the current needs of the company. That is why the majority of organizations create models which process huge amounts of data in real-time and are able to immediately find recurring patterns and detect possible anomalies or errors which would normally go unnoticed by a human eye.
It is especially useful for security purposes. In case of behaviors on users’ accounts that seem alerting, the system can notify the administrator who is able to take immediate action and check whether a danger was real.
Another area that can benefit from data science is sales. Since by analyzing data, you can predict future events, trends, and behavior, it is also possible to forecast sales in upcoming months. Thanks to data science, sellers may avoid overproduction or run out of the most popular supplies.
Naturally, the way in which a company will benefit from data science is dependent on the industry and individual needs of the company. For example, financial institutions are usually most interested in assessing risks of investments and ensuring security, while e-commerce businesses will be focused on controlling stock and marketing purposes.
How can you begin a career in data science?
Both, data science and computer science require similar basic knowledge of computers and technology. That is why data scientists should also master computer science. Each data scientist during the academic course should study fields such as statistics, linear algebra, and calculus.
