Data Science vs Machine Learning – An overview

Admin | August 16, 2022

Key takeaways:

  • Starting with statistics, data science has expanded to incorporate ideas and methods from the Internet of Things, machine learning, artificial intelligence, and many other fields.
  • Data science employs machine learning, artificial intelligence, and data mining methods.
  • Machine learning is a type of AI that employs algorithms to extract data and forecast future trends.
  • Both data science and machine learning have grown to become the top career choices across the globe.

Data science and machine learning are two ideas in the technology field that help us create and invent new goods, services, infrastructure systems, and other things by using data. Both represent highly sought-after and lucrative career opportunities. The two are related in the same manner: squares are rectangles, but rectangles are not squares. Data science is the all-encompassing rectangle. However, machine learning is a distinct square.

The significant difference between machine learning and data science is that, on the one hand, data science focuses on improving data visualisation and presentation, whereas machine learning focuses on learning algorithms and learning from real-time data and experience. Let us take a closer look at some other differences between the two with the help of the following table –

What is data science?

Data science is the study of data and how to derive insights from structured and unstructured data using various approaches, algorithms, systems, and tools. This expertise can be used in enterprises, government agencies, and other organisations to boost profits, develop new goods and services, enhance public systems and infrastructure, and more.

Data science processes

The systematic approach to solving a data problem is known as the data science process. It offers a methodical framework for formulating your issue as a question, choosing a course of action, and subsequently outlining the proposed action to stakeholders.

  • Discovery

Acquisition of data from all designated internal and external sources is part of the discovery stage, which aids in responding to the business issue.

  • Preparation

Data must be cleaned of irregularities, such as missing numbers, blank columns, or erroneous data formats. Before modelling, data needs to be processed, explored, and conditioned. 

  • Model planning

You must choose the approach and strategy to illustrate the relationship between the input variables at this stage. Among these programmes are SAS/access, R, and SQL Analysis Services.

  • Model Construction

In this stage, the real model construction process begins. Here, a data scientist distributes training and test datasets. The training data set uses methods including association, classification, and clustering. 

  • Put into practice

In this stage, you submit the baselined model in its final form along with reports, code, and technical documents. After extensive testing, the model is introduced into a live production setting.

What is machine learning?

Machine learning is a kind of artificial intelligence that uses algorithms to extract data and forecast future trends. There are several types of machine learning which are used and implemented accordingly. Models are coded into software, enabling engineers to undertake statistical analysis to understand significant  trends in data.

The machine learning algorithm is a set of techniques and concepts used in data science but also emerges in domains outside of data science. Machine learning is frequently used by data scientists in their work to help acquire more information faster or to assist with trend analysis.

Machine learning processes

The process of creating systems that learn and develop on their own through carefully designed programming is known as machine learning. Designing algorithms that automatically assist a system in gathering data and using that data to learn more is the ultimate goal of computer vision.

  • Data collection

As you know, machines initially pick up knowledge from the data you provide them. It is crucial to gather trustworthy data so your machine learning model can identify the proper patterns. 

  • Preparing the data

You must prepare your data after you receive it. This is possible by –

  • Combining and randomising all of the data you have. This ensures that the distribution of the data is balanced and that the learning process is unaffected by the ordering.
  • Cleaning the data removes unnecessary information, missing values, duplicate values, rows, and columns, data type conversion, etc.
  • Choosing a model

After applying a machine learning algorithm to the data you’ve gathered, a model you choose for machine learning will determine the results. Selecting a model that applies to the current task is crucial. 

  • Training the Model

In machine learning, training is the most crucial stage. You feed your machine learning model the prepared data during training to detect patterns and generate predictions. As a result, the model acquires knowledge from the data to complete the given task. 

  • Evaluation of the model

After training your model, you must assess its effectiveness. To do this, the model’s performance is analysed with the help of data that has never been seen before. 

Applications of machine learning

Many sectors can benefit from deploying and enhancing machine learning (ML) procedures. ML is currently used without restrictions in many different disciplines and companies.

  • Image recognition
  • Speech Recognition
  • Traffic prediction
  • Self-driving cars
  • Email Spam and Malware Filtering
  • Virtual Personal Assistant

Machine learning skills

To be a competent machine learning engineer, you should be knowledgeable in the following areas –

  • Computer science knowledge, such as data structures, algorithms, and architecture
  • Excellent knowledge of statistics and probability
  • Software engineering and system design knowledge
  • Programming skills, including Python, R, and others
  • Data modelling and analysis abilities
