Dangers of Data Science

2023-08-31 19:54:07 UTC

Data science, machine learning, artificial intelligence. These are all buzz words that have emerged in our society. We have grown increasingly reliant on these technologies, but this growing reliance also raises questions about how justified we are in giving our complete trust to these technologies. Machine learning and deep learning are known famously to be a black box — we feed data into the model and come up with some results that we just take for granted, without really questioning how these results were obtained, and whether the process is justified. This issue formed the backdrop of the keynote presentation by Professor Lise Getoor at the 2019 IEEE Big Data Conference held in Los Angeles on 10 December 2019, and I will now give an overview of the enlightening talk she gave.

What is the relationship between Data Science and Analytics?

2023-08-31 19:54:24 UTC

The relationship between Data Science and Data Analytics is less close than most people realize. It is common to hear the two terms used interchangeably, but they carry different implications for the businesses they are applied to.

When talking about Data Science we are not talking about just one thing. The term encompasses a number of specialties, methods and models that are used to understand data. It is the ability to connect the dots and connect information that is useful for a company.

Analytics is a very specific piece of Data Science. It has a clearer focus and more limited applications than those that fall under the Data Science term.

In Analytics, the goal is to filter data so that it provides insights into particular areas of the enterprise. It's as if its function were to collect data that a company knows it has and knowledge it already has, and point out how they can be used to interpret events.

If Data Analytics is part of Data Science, understanding the distinction between both is identifying which one should be the focus of a business's investments. Those who need more limited analyzes that respond to the aforementioned points do not have a reason to invest in a Data Science framework right away. With the help of a data analyst, you can get all the information you need.
