Data Science vs Machine Learning vs Artificial Intelligence – styxor.com

While the terms Data Science, Artificial Intelligence (AI), and Machine learning fall in the same domain and are connected, they have specific applications and meanings. There may be overlaps in these domains now and then, but each of these three terms has unique uses. 

Here is a brief about Data Science vs. Machine Learning vs. AI in a shorter video version.

What is Data Science?

You must have wondered, ‘What is Data Science?’. Data science is a broad field of study about data systems and processes aimed at maintaining data sets and deriving meaning from them. Data scientists use tools, applications, principles, and algorithms to make sense of random data clusters. Since almost all kinds of organizations generate exponential amounts of data worldwide, monitoring and storing this data becomes difficult. Data science focuses on data modeling and warehousing to track the ever-growing data set. The information extracted through data science applications is used to guide business processes and reach organizational goals.

Scope of Data Science

One of the domains that data science influences directly is business intelligence. Having said that, there are specific functions for each of these roles. Data scientists primarily deal with huge chunks of data to analyze patterns, trends, and more. These analysis applications formulate reports which are finally helpful in drawing inferences. A Business Intelligence expert picks up where a data scientist leaves – using data science reports to understand the data trends in any particular business field and presenting business forecasts and course of action based on these inferences. Interestingly, a related field also uses data science, data analytics, and business intelligence applications- Business Analyst. A business analyst profile combines a little bit of both to help companies make data-driven decisions.  

Data scientists analyze historical data according to various requirements by applying different formats, namely:

  • Predictive causal analytics: Data scientists use this model to derive business forecasts. The predictive model showcases the outcomes of various business actions in measurable terms. This can be an effective model for businesses trying to understand the future of any new business move.  
  • Prescriptive Analysis: This kind of analysis helps businesses set their goals by prescribing the actions which are most likely to succeed. The prescriptive analysis uses the inferences from the predictive model and helps businesses by suggesting the best ways to achieve those goals.

Data science uses many data-oriented technologies, including SQL, Python, R, Hadoop, etc. However, it also extensively uses statistical analysis, data visualization, distributed architecture, and more to extract meaning out of sets of data.

Data scientists are skilled professionals whose expertise allows them to quickly switch roles at any point in the life cycle of data science projects. They can work with Artificial Intelligence and machine learning with equal ease, and data scientists need machine learning skills for specific requirements like:

  • Machine Learning for Predictive Reporting: Data scientists use machine learning algorithms to study transactional data to make valuable predictions. Also known as supervised learning, this model can be implemented to suggest the most effective courses of action for any company. 
  • Machine Learning for Pattern Discovery: Pattern discovery is essential for businesses to set parameters in various data reports, and the way to do that is through machine learning. This is unsupervised learning where there are no pre-decided parameters. The most popular algorithm used for pattern discovery is Clustering.

Data Science Skills

Some Data Science skills include:

  • Programming: R, Python, SQL, SAS, MATLAB, STATA 
  • Data Wrangling: Cleaning, Manipulating, and Exploring Data 
  • Data Visualization: Creating graphs and charts to visualize data 
  • Data Analysis: Conducting statistical analyses of data 
  • Machine Learning: Building algorithms to learn from data

What is Artificial Intelligence?

AI, a rather hackneyed tech term used frequently in our popular culture – has come to be associated only with futuristic-looking robots and a machine-dominated world. However, in reality, Artificial Intelligence is far from that.

Simply put, artificial intelligence aims at enabling machines to execute reasoning by replicating human intelligence. Since the main objective of AI processes is to teach machines from experience, feeding the correct information and self-correction is crucial. AI experts rely on deep learning and natural language processing to help machines identify patterns and inferences.

Scope of Artificial Intelligence

  • Automation is easy with AI: AI allows you to automate repetitive, high-volume tasks by setting up reliable systems that run frequent applications.
  • Intelligent Products: AI can turn conventional products into bright commodities. When paired with conversational platforms, bots, and other intelligent machines, AI applications can improve technologies.
  • Progressive Learning: AI algorithms can train machines to perform any desired functions. The algorithms work as predictors and classifiers.
  • Analyzing Data: Since machines learn from the data we feed, analyzing and identifying the correct data set becomes very important. Neural networking makes it easier to train machines.

Artificial Intelligence Skills

Some artificial intelligence skills include: 

  • Data analysis 
  • Pattern recognition 
  • Machine learning 
  • Natural language processing 
  • Robotics 
  • Predictive modeling 
  • Computer vision 
  • Expert systems

What is Machine Learning?

Machine Learning is a subsection of Artificial intelligence that devices mean by which systems can automatically learn and improve from experience. This particular wing of AI aims to equip machines with independent learning techniques so that they don’t have to be programmed. This is the difference between AI and Machine Learning.

Machine learning involves observing and studying data or experiences to identify patterns and set up a reasoning system based on the findings. The various components of machine learning include:

  • Supervised machine learning: This model uses historical data to understand behavior and formulate future forecasts. This learning algorithm analyzes any training data set to draw inferences that can be applied to output values. Supervised learning parameters are crucial in mapping the input-output pair. 
  • Unsupervised machine learning: This ML algorithm does not use classified or labeled parameters and focuses on discovering hidden structures from unlabeled data to help systems infer a function correctly. Algorithms with unsupervised learning can use both generative learning models and a retrieval-based approach. 
  • Semi-supervised machine learning: This model combines supervised and unsupervised learning elements, yet neither of them exists. It works by using both labeled and unlabeled data to improve learning accuracy. Semi-supervised learning can be a cost-effective solution when labeling data is expensive. 
  • Reinforcement machine learning: This kind of learning doesn’t use any answer key to guide the execution of any function. The lack of training data results in learning from experience, and the process of trial and error finally leads to long-term rewards.

Machine learning delivers accurate results derived through the analysis of massive data sets. Applying AI cognitive technologies to ML systems can result in the effective processing of data and information.

Relationship between Data Science, Artificial Intelligence, and Machine Learning

Artificial Intelligence and data science are a wide field of applications, systems, and more that aim at replicating human intelligence through machines. Artificial Intelligence represents action-planned feedback of Perception.

Perception > Planning > Action > Feedback of Perception
Data Science uses different parts of this pattern or loop to solve specific problems. For instance, in the first step, i.e., Perception, data scientists try to identify patterns with the help of the data. Similarly, in the next step, i.e., planning, there are two aspects:

  • Finding all possible solutions
  • Finding the best solution among all solutions

Data science creates a system that interrelates the points above and helps businesses move forward.

Although it’s possible to explain machine learning by taking it as a standalone subject, it can best be understood in the context of its environment, i.e., the system it’s used within.

Simply put, machine learning is the link that connects Data Science and AI. That is because it’s the process of learning from data over time. So, AI is the tool that helps data science get results and solutions for specific problems. However, machine learning is what helps in achieving that goal. A real-life example of this is Google’s Search Engine.

  • Google’s search engine is a product of data science
  • It uses predictive analysis, a system used by artificial intelligence, to deliver intelligent results to the users
  • For instance, if a person types “best jackets in NY” on Google’s search engine, then the AI collects this information through machine learning
  • Now, as soon as the person writes these two words in the search tool “best place to buy,” the AI kicks in and, with predictive analysis, completes the sentence as “best place to buy jackets in NY,” which is the most probable suffix to the query that the user had in mind.

To be precise, Data Science covers AI, which includes machine learning. However, machine learning itself covers another sub-technology — Deep Learning.

Deep Learning is a form of machine learning. Still, it differs in the use of Neural Networks, where we stimulate the function of a brain to a certain extent and use a 3D hierarchy in data to identify patterns that are much more useful.
