While a Data Scientist works with data as their main activity, it doesn't mean that mathematical knowledge is something we do not need. Data scientists need to learn and understand the mathematical theory behind machine learning to efficiently solving business problems. The mathematics behind machine learning is not just a random notation thrown here and there, but it consists of many theories and thoughts. This thought creates a lot of mathematical laws that contribute to the machine learning we can use right now. Although you could use the mathematics in any way you want to solve the problem, mathematical laws are not limited to machine learning after all.

When COVID-19 hit, organizations using traditional analytics techniques that rely heavily on large amounts of historical data realized one important thing: Many of these models are no longer relevant. Essentially, the pandemic changed everything, rendering a lot of data useless. In turn, forward-looking data and analytics teams are pivoting from traditional AI techniques relying on "big" data to a class of analytics that requires less, or "small" and more varied. Transitioning from big data to small and wide data is one of the Gartner top data and analytics trends for 2021. These trends represent business, market and technology dynamics that data and analytics leaders cannot afford to ignore.

Today, companies across society are applying AI to optimize internal processes to improve the quality and performance of their existing products, to design new products and/or to further optimize the workforce. AI has proven to be critical for managing and predicting operations of a telecommunication network. However, most of the time, AI is restricted to data scientists and data analysts who are specialists specifically trained in AI. At the same time, it's the subject matter expert, i.e., experienced engineers and technicians who have the expert knowledge in a specific business or technical area. They generally also own the data. One way of bringing AI closer to the subject matter expert (SME) is by democratizing AI.

Those in Single Engineer Groups (SEG) at GitLab work in the engineering department to initiate a planned or minimal maturity category into the GitLab project. The MLOps single engineer group has a focus on MLOps, which will be focused on enabling data teams to build, test, and deploy their machine learning models. This will be net new functionality within GitLab and will bridge the gap between DataOps teams, data scientists, and development teams to get data science workloads deployed to production.

This article is based on an in-depth study of the data science efforts in three large, private-sector Indian banks with collective assets exceeding $200 million. The study included onsite observations; semistructured interviews with 57 executives, managers, and data scientists; and the examination of archival records. The five obstacles and the solutions for overcoming them emerged from an inductive analytical process based on the qualitative data. More and more companies are embracing data science as a function and a capability. But many of them have not been able to consistently derive business value from their investments in big data, artificial intelligence, and machine learning.1 Moreover, evidence suggests that the gap is widening between organizations successfully gaining value from data science and those struggling to do so.2

Data science's primary purpose is to find the patterns in data using different statistical techniques and get insights from the analyzed data. New technologies and smart products are derived from a massive data explosion in the present era of Artificial Intelligence and big data. With these latest developments, the demand and need for data are growing day by day. Many businesses and companies made data a center of focus, and data also created new sectors in the IT industry. Earlier data analytics was based on surveys and statistics.

If you've been keeping up with the Kaggle News, you may be familiar with the Mechanisms of Action competition by the Laboratory for Innovation Science at Harvard recently closed. I'm proud to say that my partner, Andy Wang, and I managed to place in the top 4% -- 152nd out of 4,373 teams. What's interesting, though, is that we're relatively new to Kaggle competition. In terms of machine learning, we're not exactly professionals -- we're both students that have picked up Python and machine learning from online courses and tutorials. We didn't get gold, of course.

In the past year or two, many companies have shared their data discovery platforms (the latest being Facebook's Nemo). Based on this list, we now know of more than 10 implementations. I haven't been paying much attention to these developments in data discovery and wanted to catch up. By the end of this, we'll learn about the key features that solve 80% of data discoverability problems. We'll also see how the platforms compare on these features, and take a closer look at open source solutions available.

The global market revenues from data science activities are set to grow in leaps and bounds in the future. And hence, it is no wonder that the demand for data scientists in various industrial roles will rise in proportion to market growth. But the main question is how to get started for a career in data science? While there are specialized technical courses that can be pursued if one has a technical background, things may not be the same for someone with a non-technical (non-engineering) background. At the same time, given the gap between existing skills and required skills, it will be sometime before a non-techie finds a perfect fit in the data science market. Nevertheless, interested individuals can still succeed professionally with or without a technical background.

Apache Spark Streaming – Every company produces several million pieces of data every day. Properly analyzed, this information can be used to derive valuable business strategies and increase productivity. Until now, this data was consumed and stored in a persistent. Even today, this is an important step in order to be able to perform analyses on historical data at a later date. Often, however, analysis results are desired in real time.
