Challenges and Future Trends in Data Science
Data science is the application of data and analytics to solve problems that are frequently complex (or numerous) and unstructured. The term “fishing expedition” is used in the analytics sector to describe a project that was never planned correctly in the first place and involves looking through the data for unexpected connections. Although this particular form of “data fishing” does not follow the rules of effective data science, it is nonetheless quite widespread. Therefore, defining the problem is the first thing that must be done.
Some of the challenges in data science include:
Data Preparation for Smart Enterprise AI
A data scientist’s top priority is locating and purging the appropriate data.
According to a CrowdFlower survey, cleaning, organizing, mining, and acquiring data take up about 80% of a data scientist’s day. The data is verified twice at this level before going through more processing and analysis.
The ideal way to handle this situation is to adopt AI-based solutions that assist data scientists in keeping their competitive edge and improving their efficacy. Augmented learning is a customizable AI tool for the workplace that helps with data preparation and illuminates the subject at hand.
Data Generation from Multiple Sources
Organizations get data from various tools, software, and programs they utilize. For data scientists, managing large amounts of data is a major challenge. This method requires manual data entry and compilation, both of which take time and have the potential to lead to mistakes or needless repetitions.
Now, businesses may create complex virtual data warehouses with centralized platforms to consolidate their data sources in one place. To meet a company’s needs and boost productivity, altering or manipulating the data kept in the central repository is feasible.
Communication of Results to Non-Technical Stakeholders
A data scientist’s primary goal is to improve the organization’s decision-making capabilities, consistent with the business strategy that this role supports. Effectively conveying their findings and interpretations to corporate leaders and managers is the biggest challenge for data scientists. It is crucial to give managers and other stakeholders the correct foundational concept to apply the model using business AI because most of them are not familiar with the tools and technologies used by data scientists.
To do so effectively, data scientists must include ideas like “data storytelling” in their analyses and visualizations.
These are a few challenges faced by the data scientists. However, new technologies are now making firms more productive and improving their return on investment. Data analytics, artificial intelligence, big data, and data science. Business companies implement data-driven models to streamline operations and make decisions based on data analytics findings.
