A data scientist analyzes data to find meaningful patterns. More specifically, amassing large amounts of data, both structured and unstructured, creating models and algorithms to facilitate the storage of this data, figuring the correct data sets and variables and interpreting the data to discover opportunities and solutions.
They spend a large amount of their time cleaning data. This is done with the help of statistics, software engineering skills, and most importantly, persistence, all of which are required to understand biases in data after structuring the data in a more readable and understandable manner, visualization and sense of data.
Mining data insight and building data product, in essence, is the process of looking or analyzing data within a quantitative perspective. Correlations, textures and dimensions in the available data can be expressed mathematically. Using data to find solution acts as a manner of training for the brain for qualitative and heuristic technique. Solving business related issues is done with the help of analytical models based on hard math, wherein understanding the mechanics of them are essential to succeed in building them.
Two branches in statistics that are very used are the classical statistics and Bayesian statistics. Data science is thought to be a subject that deals solely with statistics. There's no way one can deny the importance of statistics in data science, however this is not the aspect of maths that is used. Most machine learning algorithms and inferential techniques are based on linear algebra. It hence becomes very important to have good knowledge of both the subjects to be a good data scientist.
Data available earlier was highly structured and organized. It could have been analyzed by the simple business intelligence (BI) tools, which are, nowadays, not complex enough to analyze and handle the volume of data post the advent of the internet. By using algorithms and other analytical tools, meaningful patterns are found from the data.
Take for example, if you would like to provide better customer experience by personalizing the experience for a customer. This is done by utilizing and analyzing the past data and assessment of behavior of that particular customer. The patterns of these behaviors are looked at by algorithms and are used for providing this experience. Based on their preferences, products are recommended to do so. Weather forecasting, smart cars, online shopping platforms all use data science to improve the Customer Relationship Management (CRM).
With the field opening up for exploring and experimenting, job opportunities are plentiful. Becoming a data scientist in the current atmosphere can be called nothing less than smart, and if you are someone who considers themselves creative or persistent, then you better get started soon!
As learning all of these skills on your own can be not only be cumbersome, but also a futile task, you may opt to go for data science course Singapore. Most of these institutions eventually help in placements later on once the course is complete. These companies can act as a learning platform and also provide wide scope.
