Data Science Vs Machine Learning

Data Science Vs Machine Learning

After the era of Big Data emerged in the industry of data space in 2010, Organizations had to deal with petabytes and exabytes of data, and therefore, it became very difficult for industries to store and manage the data. In the wake of Hadoop and others solving the storage issue, the focus now shifts to processing the data, where Machine Learning and Deep Learning play a big role. The concepts of data science and machine learning are both under the umbrella of technology and can be used to further the creation and innovation of products, services, infrastructure systems, and much more. Both are high-earning and in-demand careers and pursuing either of them can be rewarding.

Data science is a discipline that studies how data are cleaned, prepared, and analyzed. Furthermore, machine learning is considered to be a branch of artificial intelligence and the subfield of data science at the same time. Data Science vs Machine Learning are closely linked, yet they have distinct functions and objectives that vary from one another. The importance of understanding how these two buzzwords, together with artificial intelligence and deep learning, differ from one another is vital. Specifically, in this article, we will examine the differences between Data Science and Machine Learning and how they are related to one another.

What is Data Science?

Data science, as the name implies, is concerned with data collection and analysis. We may thus describe it as “an area of deep study of data that involves extracting valuable insights from the data and processing that information using a variety of tools such as Jupyter, MATLAB, BigML, Apache Spark, etc., statistical models, and Machine learning algorithms like Linear Regression, Logistic Regression, Decision Tree, etc,” Wikipedia. It is a domain of study concept that is used to manage large amounts of data, and it involves data cleansing, data preparation, data analysis, and data visualization.

A data scientist gathers raw data from various sources, prepares and pre-processes the data, and then uses machine learning algorithms and predictive analysis to derive valuable insights from the data gathered and stored.

Data Collaborative filtering, a technique used by data scientists to make an automatic prediction for a user regarding their interests based on the data collected from various users. For example, Netflix uses this technique to provide better recommendations for search results based on the content that the user has previously watched and the content that is being watched by other users.

Data Scientists must possess a variety of abilities like:

  • Skills in programming languages like Python, R, SAS, Scala, and other programming languages.
  • Expertise in databases like SQL, MongoDB, and Cassandra.
  • Understanding of Machine Learning Algorithms is required.
  • And mathematics topics like Statistics, Calculus and Linear Algebra, etc.
  • Data mining, cleansing of data, and visualization abilities are required.
  • Competencies in the usage of big data technologies such as Hadoop, Apache Spark, Tensor Flow, Data Lakes, etc.

What is Machine learning?

In artificial intelligence (AI), machine learning allows systems to automatically learn from data and predict development on their own without the need to be explicitly designed in advance. The creation of virtual personal assistants, GPS Navigation Services, Social Media services, fraud detection services, chatbots, etc. is plenty of subjects of learning research and development.

We begin the process of learning with observations or data (such as examples, first-hand experience, or teaching) to identify patterns in data and make better choices in the future based on the examples we give. The main goal is to enable computers to learn on their own, without the need for human involvement or help, and to modify their behaviour appropriately.
