Data science is a blend of various algorithms, tools, and machine learning principles that operate with the goal of discovering hidden patterns from raw data. Machine learning is a subset of artificial intelligence. This refers to machines being able to learn by themselves without being explicitly programmed. It is an application of AI which enables systems to learn and improve from experience automatically. While working with machine learning, various sets of algorithms are required. These algorithms use a set of training data to enable computers to learn.
Data scientist and machine learning engineer jobs are the two current hottest jobs in the industry and for a good reason as data has become part and parcel of our lives today, and massive amounts of data are being generated both by individuals and businesses across all industries. In this article, we will analyze the career paths of data scientists and machine learning engineers.
Who is a Data Scientist?
A data scientist makes decisions and predictions by using prescriptive analysis, predictive causal analysis, and machine learning. He is responsible for scoping out the right questions from the dataset. He works at the raw level of data (structured, unstructured, or both) to make predictions, identify patterns and trends, build data models, and create more efficient machine learning algorithms. Data science experts work in the realm of the unknown. Some of the techniques used by data scientists are regression analysis, classification analysis, clustering analysis, association analysis, and anomaly detection.
Who is a machine learning engineer?
A machine learning engineer is a sophisticated programmer who develops systems and machines that can learn and apply knowledge with specific instructions or guidance. They create programmes that aid machines in taking actions without being specifically directed to perform those tasks. Artificial intelligence is the primary goal of a machine learning engineer.
Data Scientist vs Machine Learning Engineer- Common Skillsets Needed
The common skillsets needed are:
- Statistics– It is defined as the study of the analysis, interpretation, collection, organization, and presentation of data. Data scientists and machine learning engineers must know statistics to a great extent. They must be familiar with matrices, vectors, and matrix multiplication.
- Data Cleaning and Visualization– Data cleaning or data cleansing is a valuable process that helps companies save time and increase efficiency. It is crucial to be able to tell a compelling story with data to keep your audience engaged and get your point across. Findings must be in such a way that they can be identified easily and quickly. Otherwise, it will be difficult to get it through to others. Data visualization has a make-or-break effect when it concerns the impact of your data.
- Machine Learning and Neural Network Architectures– Machine learning and predictive modelling are two of the hottest topics. Both data scientists and machine learning engineers must know techniques such as decision trees, logistic regression, and supervised machine learning, etc. These will aid in solving different analytical problems based on the predictions of major organizational outcomes.
- Computer Vision– Machine learning and computer vision are two core branches of computer science that function and power sophisticated system relying on computer vision and machine learning algorithms exclusively. But when both are combined, you can achieve even more.
Some of the specific skills a machine learning engineer must have are applied mathematics, software development, signal processing techniques, and language, audio, and video processing. The specific skills pertaining to a data scientist are effective communication, creative and critical thinking, and decision-making and problem-solving skills.
