Data science is undoubtedly one of the most priced assets of the 21st century. The value that would be attached with data in the coming times is difficult to envisage. This is because each and every sector would depend upon the data pipeline in one or another way. This highlights the importance of world of data science and the unilateral impact that it would have on the job market.
That said, data science is rather an emerging field and people are getting slowly acquainted with its importance. They are trying to learn data science from scratch as it is predicted to be at the center stage of the impending data revolution. Let us take a close look at the various facets of this subject in deeper detail.
The whole new world of data science
Data science is a whole new world in itself because its scope forms the incircle of subjects like artificial intelligence, machine learning, big data engineering, data insights, analytics, visualization, and business intelligence. Data is sourced from different kinds of images, numbers, and even videos. The first important step is to gather structured information from unstructured data sets so that they can be subjected to rigorous cleaning. Data in a processed shape is then used for deriving insights and forecasting various trends. This is especially important for business intelligence which is highly dynamic and subject to the fluctuations of the market. In addition to this, business forecasting reduces the cost of operations and optimizes investment in new products and services.
Data intelligence is also helpful in e-commerce and other digital ventures. Various kinds of data-driven techniques are used to determine customer behavior and target them with desired products. This enables us to perform personalized recommendations and get better returns by keeping a track of customer journeys.
The raw material of data science
Big Data forms the raw material of data science. The voluminous amount of data that is generated in the present times is a testimony of the upcoming data wave that we may be confronted with. As such, the traditional ways of processing data may need to undergo modification. Another option that is available to us is to rely on big data analytics for the purpose of data processing. A large number of tools are used by data scientists in this regard. Some of the most prominent ones include Hadoop, Scala, and Apache SPARK.
Technical skills for data science
The mastering of technical skills is extremely crucial when it comes to data science. The various technical challenges related to machine learning can be counted effectively with the help of programming languages like python. The knowledge of python is a prerequisite for the development of models run with the help of machine learning. Python and machine learning techniques are also a precursor for sci-kit learning. Technical skills for data science have to be learned in consonance with mathematics and statistics. Together, they help in the formulation of machine learning algorithms that form the neural schema of modern artificial intelligence systems. The knowledge of mathematics incorporates topics like matrix transformation and linear transformation. Moreover, the knowledge of vectors like the cross product and dot product is also essential. The theoretical knowledge of application prospects is also necessary for a machine learning engineer. The core concepts of machine learning like classification and regression owe their origin to statistics. The concepts which are described here not only help in hypothesis testing but also aid in the design of an experiment. The performance of the experimental setup can also be tested and optimized with the help of machine learning techniques.
The life cycle of data science
The life cycle of data science starts with data collection and data visualization. There are three intermediate stages between the first and the final stage. The second stage includes data discovery which helps in capturing structured meaning from vast data sets. The third stage involves the preparation of data so that a level of uniformity is attained. The second last stage involves the construction of mathematical models which can be finally used for decision-making purposes.
It is highly recommended to start mastering data science from scratch because data skills would form the first requirement of all jobs in industry 4.0.
