30 Nov Top 8 Differences Between Data Science and Machine Learning
Data science and machine learning are the two most important concepts in big data.
Data Science is a broader term that encompasses all aspects of data analysis, whereas machine learning is a subset of data science that focuses primarily on predictive modeling and classification.
We will go over the top 10 differences between these two fields below.
1. Data scientists use machine learning to make predictions about the future
Data scientists use machine learning to make predictions about the future whereas data science is more focused on analyzing past data to find insights and explain patterns.
Data science is a broader term that encompasses all aspects of data analysis, including predictive modeling and classification.
Machine learning is only one part of the data scientist’s toolkit for making predictions, about what might happen in the future based off our past observations.
Data scientists use machine learning models as tools to help them make decisions, about which dataset or variables they should analyze next when solving a problem or working toward an objective.
Machine Learning focuses primarily on predictive modeling and classifications problems—including supervised and unsupervised approaches, as opposed to using it simply as a decision-making aid like data scientists do.
Machine Learning can only work with what it has been trained on, while Data Science draws from all available data sources in order to create insights.
This difference is by far one of the biggest distinctions between these two disciplines because machine learning is more time consuming, code development, energy consumption, computational power/memory than data sciences does.
Data Science and Machine Learning are two distinct fields of data-driven work.
Data Scientists primarily use data to find patterns or connections that lead to predictions about the future, while Machine Learning focuses on predictive modeling and classifications problems–including supervised and unsupervised approaches–as opposed to using it as a decision making aid like data scientists do.
The other big distinction is that data scientists mainly focus on questions data, data that has a definite answer while machine learning focuses on data with no definitive conclusion.
Data scientists mainly focus on question data, data that has a definite answer.
Machine Learning is focused more on data without an obvious conclusion- like natural language processing and speech recognition–which means it requires different skill-sets than Data Science does.
The major distinction between these two disciplines comes down to the fact that machine learning needs more time, code development, energy consumption in order for the models to run efficiently enough as well as computational power/memory.
Furthermore, Data Scientists primarily use data to find patterns or connections which lead to predictions about future events; whereas Machine Learning focuses on predictive modeling and classification problems including supervised and unsupervised approaches.
2. Machine Learning is a subset of Artificial Intelligence
Machine Learning is a subset of Artificial Intelligence. It is an interdisciplinary field that studies the construction and study of algorithms, which are used to make predictions or decisions based on data.
Machine learning focuses on developing computer systems that can learn from their experience without being explicitly programmed by humans.
For machine learners, this means using statistical techniques such as clustering, classification and regression analysis in order to find patterns in large datasets with unknown variables.
The development of machine learning has been driven by insights from fields like probability theory, statistics, pattern recognition and computational neuroscience; it has applications in many domains including search engines (e-commerce) (such as Google), image processing (automotive) and cognitive psychology research.
3. Data Scientists are more focused on data collection and organization
The data scientist is a person that organizes and interprets large amounts of data for businesses.
This individual does not necessarily need to have expertise in math or statistics but instead has other skilled sets which can help business owners make sense of what may be overwhelming quantities of information.
Data scientists collect any type of applicable data from surveys, experiments, customer records, social media interactions etc then organize it into databases where it can be retrieved by others when needed.
4. Machine Learning is more focused on using algorithms to predict the future
In data science, the data is always a priority. In machine learning, data sets are typically secondary to models and algorithms.
Machine Learning is a field of computer science that uses algorithms to learn from data and make predictions.
The algorithms are not programmed by humans, but instead the algorithm learns from the data it encounters.
Machine learning can be applied in many different fields including finance, healthcare, autonomous driving, and more.
The advantages of machine learning include rapid prototyping due to automated processes as well as improved quality of solutions because minor changes in input don’t require major code changes for training models.
Additionally, machine-learning systems are adaptive so they learn with time which allows them to avoid overfitting or underfitting their model.
However, there are disadvantages to using machine learning such as biases that may exist within the system’s training data or lack of understanding
5. Machine Learning can be used in many different fields, such as medicine, finance, manufacturing, education, and law enforcement
The use of machine learning in different fields is becoming more prevalent.
One such field that has seen an increasing number of studies and implementations is medicine. Machine Learning can be used to analyze patient data, which will help doctors make better medical decisions.
The potential for the application of this technology in other areas cannot be ignored either; it could lead to major changes in how we live our lives.
Machine Learning has already been proven useful when analyzing tumor images, which led to a higher rate of accuracy than traditional methods .
This information is vital because even a small change in diagnosis can have life-or-death consequences for patients with cancer or other diseases that may present similar symptoms at first glance.
6. Data Science is often found in areas like marketing or advertising where there may not be enough data for machine learning to work effectively
Data Science is often found in areas like marketing or advertising where there may not be enough data for machine learning to work effectively.
It is useful in these areas because data scientists can use data visualization to make predictions about the future, which are then translated into marketing and advertising campaigns.
One of the biggest differences between data science and machine learning comes down to what kind of questions it asks:
Does a particular advertisement increase or decrease sales?
Will changes I make on this website improve customer satisfaction?
7.Data Scientists often have backgrounds in math or statistics, whereas Machine Learning specialists generally come from computer science or engineering disciplines.
The data scientist is more concerned with the question, “What do we know?” while data scientists are more focused on asking questions to find what they don’t yet understand.
Machine-learning specialists focus on answering specific queries such as:
Does this new website design look better than the old one?
I want a system that will identify spam e-mail messages before they reach my inbox. How can I get an app like Uber or Facebook to predict when I need it and where am I going next?
Data Scientists are usually hired for their statistical skills, whereas Machine Learning experts have backgrounds in mathematics, computer science (particularly statistics) and engineering disciplines.
So data scientists often come from math/statistics backgrounds because they’re trying to answer data-related questions, while machine learning experts come from computer science and engineering backgrounds because they’re focused on solving specific problems.
In contrast to data scientists who are often hired for their statistical skills, data scientists also need strong analytical abilities in order to manipulate data sets that can be quite large and complex.
Machine Learning specialists (MLs) typically have a math/statistics background or an understanding of how computers work at the programming level.
MLs usually don’t know any more about statistics than what’s needed to use it as a tool; you’ll find them designing algorithms that take advantage of modern technology like GPUs instead.
The job outlook for data science jobs are currently much higher than those for machine learning jobs because there’s more demand for people who can extract value from data than those who know how to build computer models that do it automatically
8.Data Scientists should also have knowledge of data visualization tools, database management systems (DBMS), and statistical software packages like SPSS or SAS. Data scientists need to be able to communicate their findings effectively in a way that’s understandable by other people outside the specialty area
Machine learning specialists are more likely to use R programming language than data science professionals who will often prefer Python for writing scripts that can extract meaning from data sets.
Machine Learning jobs require computer coding skills; data scientist positions don’t always necessarily include this requirement, even though machine learning algorithms depend on data being coded properly before they’re put into production.
Data Science offers lower barriers for entry because it doesn’t normally involve as much programming know-how as ML does.
