For one to be able to practice as a data scientist, a combination of technical and non-technical skills is required. These include programming languages that pull/manipulate/analyze data using Python or R, and SQL is used in handling databases. Statistical and mathematical literacy is basic to data and the models that are put forward.
Knowledge about machine learning algorithms is also important, and knowing how to utilise them is crucial. More so, there is a need for skills in data visualization to enable the presentation of insights in simple and easy to comprehend ways to the stakeholders. I believe that soft skills such as problem-solving skills, communication skills and business skills are useful in comprehending real life issues and in coming up with solutions.
Who is a data scientist?
A data scientist is an analyst with understanding, knowledge, and skills that are immediately appropriate to a difficulty or opportunity that involves gaining information from large data sets. They apply knowledge in programming, statistician, and machine learning to predict and analyze various trends, making it easy for organizations to make business decisions.
Business intelligence specialists are responsible for dealing with big amounts of information, transforming it into useful data that will assist in managing companies’ processes, understanding consumers’ responses, and creating unique services and products. Cross-industry knowledge in the healthcare sector, financial services, retail and technology with the application of data science that delivers predictive models to business, improving customer satisfaction and automating choices. The ideas sourced from data are all about growth, efficiency, and competitiveness, and as such, data scientists are very useful.
An iit madras data science course enriches the knowledge of the toolkit and ideas most important for data analysis, machine learning, and big data tools and platforms. The course applies theoretical concepts and provides learners with meaningful and practical projects to help them acquire skills necessary for careers as Data Scientists and develop their competence for careers in new related fields.
How is machine learning applied in data science?
Machine learning is one of the major constituents of data science and it is the art of training a computer program on a set of data that is capable of dealing with a range of scenarios, where the program itself will be getting to a decision without being programmed. Originally, machine learning relates to the utilization of data sets and elaborate tools in efforts to ascertain key trends and produce potential predictor values. It assists in developing decision-making models, including sales forecasts, customer categorizing, and face recognition. For specialized issues, ordinary regressions and classifications are applied through supervised learning, while for basic groupings, unsupervised learning is used. It is a form of machine learning, although probably the most pervasive one, and its application fields include image identification, voice and textual analysis. Machine learning allows data science professionals to develop intelligent programs for simple and efficient identification of patterns out of the large sets of data in the present practical problems.
