Machine Learning Engineer vs Data Scientist: Roles, Responsibilities, Skill Set And More
“Engineering, I think you can pick up. [A data scientist’s] curiosity is built-in.” – Scott Nicholson
As popularly said by William Deming – “In God we trust; all others must bring data.”, the world is driven by data. Two technical terminologies that deal with the huge heaps of organizational data are Machine Learning and Data Science. Both sound confusing to many, not understanding what lies underneath and how different they are. It is Artificial Intelligence Services that plays a pivotal role in leveraging data science and machine learning. The highly significant roles of Data Scientists and Machine Learning engineers have their own set of responsibilities to play and requirements to fulfill.
Before we plunge into understanding the different roles and responsibilities that each data scientist and machine learning engineer must play, let us quickly glance through the main technologies behind these roles.
Data Science – An Overview
“Data Scientists are involved with gathering data, massaging it into a tractable form, making it tell a story, and presenting that story to others.” – Mike Loukides
Data Science focusses on extracting the actionable perceptions from base data. It is all about working and managing data that forms the crux of all organizations and all businesses.
It consists of several specialties that offer a complete and valuable output to the base data.
It can be used for a variety of activities such as detecting anomalies, automating activities, forecasting different parameters, detecting patterns, facial/vocal/text recognition, recommending preferences, etc.
Data science depends on Artificial Intelligence for making models and predictions with the help of varied algorithms and methodologies.
Data science has been providing extensive services to different industry segments like
- Healthcare – Clinical database, practicing newer techniques to treat patients, faster diagnosis, personal fitness tracking, etc.
- Self-Driving Cars – Predictive analytics, cameras, and sensors to find real-time information adjusting speed limits, preventing dangers, finding the fastest routes, etc.
- Logistics – Maximizing efficiency with modern-day tools, statistical modeling, optimal route creation, weather forecasting, and actionable insights, etc.
Machine Learning – An Overview
“A breakthrough in machine learning would be worth ten Microsofts. – Bill Gates
Machine Learning is a direct AI application that gives the capability of learning and enhancing from experience, without the programming fuss. It is a complete process that guides the computer system to predict as the data is piled on.
ML leverages the power of statistics for patter extraction amongst the wide coverage of data. It analyses the data and extracts the rules that exist behind an issue, leading to complex tasks getting solved. It helps in enhanced decision-making with techniques such as sales forecasting etc.
It analyses and extracts hidden patterns from data with valued insights. It assists in enhancing the precision of financial models.
Application areas of machine learning include the following industry segments, and much more:
- Finance – Manages financial portfolios, finds out cyber frauds, assesses risks and other irregularities
- Healthcare – Helps the healthcare segment in searching for patients with complications and needing emergency treatment, improves patient experience
- Manufacturing – offers robust preventive maintenance plans with lesser risk-taking and avoiding failures
- Sales & Marketing – Analysis of customer background, needs, likings with ML models. Searches for hidden patterns and trends to find the most liked products, client wise.
Data Scientist vs Machine Learning Engineer -The Roles To Play
As we begin to compare the details of both these important roles, here are certain attributes that are looked for, in both, as common traits:
- Good grip on programming languages (C, C++, Python, R, Java, etc.)
- Experience with statistics, matrices, vectors, etc.
- Data visualization and cleaning
- Machine learning and Big Data frameworks
- Industry proficiency
- Problem-solving skills
- Strong understanding of the industry
