Our hardworking ancestors have taught us about the disadvantages of shortcuts and the fact that they never work. This stands true even in the age of reason as Jean-Paul Satre points out, “ The best work is not what is most difficult for you; it is what you do best.” Best work never entails shortcuts because the best of works take a good amount of time and patience.

However, the age we are currently residing in is also known as an age of convenience where every facility is available on small portable devices. This hyper-availability of services and privileges has curtailed the concept of attentive and intricate work even on AI experts and scientists.

New research from the University of Washington unveils that AI-powered gadgets too are inclined to shortcuts like humans. This tendency of relying on shortcuts is justified by the fact that artificial intelligence mimics human intelligence after all.

The Major Adversaries Entailed in Healthcare When AI takes Shortcuts

Doctors and medical experts have expressed their intimidation and indignation on the major cons that AI shortcuts can result in. If AI tools are deployed in the medical practice, they can yield erring results that can have a negative impact on the diagnoses of patients.

Alex DeGrave, a medical student at the University of Washington, along with his fellow students has discovered that the algorithms deployed in testing Covid-19 patients, relied on text markers and patient positioning, specific to each data set to detect a COVID-19 positive patient.

In DeGrave’s words, a physician relies on specific patterns of the image that reflects disease processes. However, a system using shortcut learning instead of relying on the patterns can give rise to risky repercussions in the process of diagnosis and treatment.

Such a problem of leaning on shortcuts is termed as lack of transparency, also known as the “black box” phenomenon. Researchers have found that this problem is existent in almost all COVID-19 detection models. Medical practitioners have also highlighted the “Worst-case confounding”. Worst-case confounding is a situation in which an AI tool lacks a sufficient amount of training data to learn the underlying pathology of a disease. Such a problem occurs when a model is removed from its original setting.

The team of medical practitioners trained the deep convolutional neural networks on an X-ray image from a specific data set. It was observed that the model’s test performance faltered when it was removed from its original setting and the accuracy level fell by half when the model was exposed to the external environment.

Su-In Lee, a PhD associate professor in Allen School asserts that the study on the AI models for Covid-19 detection underscores the fundamental role that explainable AI will play in ensuring the safety and efficacy of these models in decision-making in medical science.

The world is moving at a brisk pace. Several technologies have become obsolete, while the technologies that looked impossible a few years back are at our fingertips now. Hence, it has become pertinent for young professionals to learn the skills that drive future technologies. Data Science is one such promising field. In recent years, millions of professionals have secured their future by choosing Data Science as a career. You can enter this career by completing a degree or a course in Data Science. Finding these courses has become a cakewalk these days. You can easily find a reliable Data Science course in Hyderabad or other top tech cities to boost your career growth. But before we move ahead, let us look at this field in more detail. 

Who is a Data Scientist?

The world economy is leaning more towards analytics, with companies collecting data for many years. According to LinkedIn, there is an enormous demand for professionals who can mine and interpret data. These are the Data Scientists.

Data scientists are a mix of mathematicians, trend-spotters, and computer scientists. The data scientist’s role is to decode large volumes of data and analyze it further to find trends in the data and gain an insight into what the data suggests. Data scientists work between the business and the IT worlds. They drive markets by analyzing complex datasets to reveal insights that companies can leverage into actions.

Skills Required For Data Scientist

If you want to have a career in data science, you will need hard skills like analysis, machine learning, statistics, Hadoop, etc. Excelling in this role requires excelling at critical thinking, persuasive communication, and having good listening and problem-solving skills. 

Opportunities are plenty in this field. So, once you have the skill-sets and qualifications, the jobs are waiting for you—now and in the future.

Job Roles for Data Science Experts

Most companies are embracing data analysis to skyrocket their growth. Data Scientists are in demand not just in the tech world but also in all other major sectors, including FMCG, logistics, and more. The big-five tech giants: Google, Amazon, Apple, Microsoft, and Facebook, employ half of the world’s total data scientists. 

Here, we discuss the lucrative Data Science careers for the aspirants:

Data Scientists:

A Data Scientist explores and scrutinizes various data patterns to estimate the impact on an organization. A Data Scientist’s role is to explain the importance of data in a simple method so that others can understand it. They require statistical knowledge of different programming languages for solving complex problems. 

Data Analyst:

A Data Analyst’s role is to analyze the data to figure out a market trend. They provide a clear picture of the company’s standing in the market. The company sets the desired goal, and then the Data Analyst provides datasets to achieve the required target.

The Data Analyst’s role changes according to the company’s needs. For example, the marketing department may need their services to understand consumer behavior and responses against various marketing strategies. 

Data Engineer:

Data Engineers work with the organization’s core and are the company’s backbone. They are the builders, designers, and managers of large databases. Their task is to build data pipelines, correct data flow, and ensure the data reaches the relevant departments.

A Data Engineer has to collaborate with other data experts to communicate the results with his colleagues. In a nutshell, a data engineer shares his insights with the company through data visualization and helps the organization grow. 

Business Intelligence Analyst:

A business intelligence analyst analyzes the collected data to maximize the company’s efficiency. They have a more technical role than analytical and require knowledge of popular machines. They are the bridge between business and IT. 

Marketing Analyst:

A marketing analyst assists companies in their marketing division. They analyze and suggest which products to produce and which products to discontinue. They monitor customer satisfaction reports to help the company in improving existing products and services.
