Data Science vs Machine Learning and Artificial Intelligence

While Data Science, Artificial Intelligence (AI), and Machine Learning are all part of the same area and are related, they each have their own applications and meanings. There may be some overlap in these sectors from time to time, but each of these three terms has its own set of applications.

What is Data Science?

Data science is a vast branch of research that focuses on data systems and processes with the goal of sustaining and deriving meaning from data sets. To make sense of random data clusters, data scientists utilise a combination of tools, applications, principles, and algorithms. It is becoming increasingly challenging to monitor and preserve data since practically all types of companies generate exponential volumes of data around the world. To keep up with the ever-growing data collection, data science focuses on data modelling and data warehousing. Data science applications extract information that is used to influence business processes and achieve organisational goals.

What is Machine Learning?

Machine Learning is a kind of artificial intelligence that uses technology to enable systems to learn and improve on their own. The distinction between AI and Machine Learning is that this branch of AI tries to equip computers with independent learning mechanisms so that they don't need to be taught to do so. Machine learning entails monitoring and analysing data or experiences in order to spot patterns and build a reasoning framework around them. The following are some of the components of machine learning:

1. Supervised Machine Learning - This model makes use of historical data to better understand behaviour and make predictions for the future. This type of learning algorithm examines any given training data set in order to draw conclusions that may be applied to output values. In mapping the input-output pair, supervised learning parameters are critical.
2. Unsupervised Machine Learning - There are no classed or labelled parameters in this form of ML algorithm. It focuses on uncovering latent structures in unlabeled data to aid systems in correctly inferring a function. Both generative learning models and a retrieval-based technique can be used in unsupervised learning algorithms.
3. Semi-Supervised Machine Learning - This approach incorporates aspects of both supervised and unsupervised learning, but it is not one of them. It improves learning accuracy by combining labelled and unlabeled data. When labelling data proves to be costly, semi-supervised learning can be a cost-effective approach.
4. Reinforcement Machine Learning - No answer key is used to guide the execution of any function in this type of learning. Learning through experience is the outcome of a lack of training data. Long-term rewards emerge from the trial-and-error process.

What is Artificial Intelligence?

AI has come to be associated only with futuristic-looking robots and a machine-dominated society, a fairly overused tech term that is regularly employed in our popular culture. Artificial Intelligence, on the other hand, is far from that. Simply put, artificial intelligence tries to enable machines to reason in the same way that humans do. Because the major goal of AI processes is to teach machines through experience, it's critical to provide the relevant information and allow for self-correction. Deep learning and natural language processing are used by AI professionals to assist robots in identifying patterns and inferences.

Relationship between Artificial Intelligence, Data Science and Machine Learning

Artificial intelligence and data science cover a broad range of applications, systems, and other topics aimed at simulating human intelligence in machines. Artificial Intelligence (AI) is a perception-action feedback system. 

Perception > Planning > Action > Perception Feedback

Different sections of this pattern or loop are used in Data Science to solve distinct challenges. For example, in the first step, perception, data scientists attempt to find patterns using data. Similarly, there are two sides to the next step, which is planning:

• Identifying all viable options
• Finding the greatest solution out of a plethora of options

Data science creates a mechanism that connects both of these areas and assists organisations in moving forward. Although machine learning can be explained as a single subject, it is best understood in the context of its environment, i.e. the system in which it is utilised. Simply described, machine learning is the interface between data science and artificial intelligence. That's because it's a long-term learning process based on data. As a result, AI is a tool that assists data scientists in obtaining answers and solutions to specific challenges. Machine learning, on the other hand, aids in accomplishing that goal. Google's Search Engine is a real-life illustration of this.

• Data science is at the heart of Google's search engine.
• It employs predictive analysis, an artificial intelligence technology, to provide consumers with intelligent outcomes.
• For example, if someone types "best jackets in NY" into Google's search engine, the AI uses machine learning to collect this information.
• Now, as soon as a user types "best place to buy" into the search tool, the AI takes over and, using predictive analysis, completes the sentence as "best place to buy jackets in NY," which is the most likely suffix to the user's inquiry.

To be more specific, Data Science encompasses artificial intelligence (AI), which includes machine learning. Machine learning, on the other hand, encompasses another sub-technology known as Deep Learning. Deep Learning is a type of machine learning that differs in that it uses Neural Networks to stimulate the brain's function to a degree and uses a 3D hierarchy in data to uncover patterns that are far more valuable.

Difference between Data Science, Machine Learning and Artificial Intelligence

Despite the fact that the terms Data Science, Machine Learning, and Artificial Intelligence are all related and interconnected, each is distinct in its own right and is used for diverse purposes. 

Machine Learning is part of Data Science, which is a broad phrase. The main distinction between the two terminologies is as follows.

Data Science VS Machine Learning and Artificial Intelligence

Jobs in Machine Learning, Artificial Intelligence and Data Science

Careers in data science, artificial intelligence, and machine learning are all profitable. The truth is that neither field is mutually exclusive. When it comes to the skill sets required for work in various domains, there is frequently overlap. Data Science jobs like Data Analyst, Data Science Engineer, and Data Scientist have been in demand for a long time. These positions not only pay well but also provide plenty of opportunities for advancement.

Some Data Science-Related Roles' Requirements 

• Programming knowledge
• Reporting and data visualisation
• Math and statistical analysis
• Risk assessment
• Techniques for machine learning
• Structure and data warehousing

A career in this domain isn't confined to programming or data mining, whether it's creating reports or breaking them down for other stakeholders. Because every function in this field serves as a link between the technological and operational departments, great interpersonal skills are required in addition to technical knowledge.

Similarly, employment in Artificial Intelligence and Machine Learning are taking a large portion of the talent pool. This domain includes positions like Machine Learning Engineer, Artificial Intelligence Architect, AI Research Specialist, and others.

Roles in Artificial Intelligence - Machine Learning necessitate technical skills:

• Python, C++, and Java are examples of programming languages.
• Modeling and evaluation of data
• Statistics and probability
• Computing on a large scale
• Learning algorithms based on machine learning

As you can see, both areas have competency requirements that overlap. Most data science and AI-ML courses offer a foundation in both, in addition to a concentration on the respective specialisations.

Despite the fact that data science, machine learning, and artificial intelligence are all related, their exact features differ and they each have their own application areas. The data science sector has spawned a slew of new services and products, providing opportunities for data scientists.

The importance of understanding the difference

Data science is a field with a lot of opportunities. It's critical to understand the differences between these phrases, which are sometimes used interchangeably, in order to choose the correct speciality for you. We hope that you now have a better understanding of what Data Science, Machine Learning, and Artificial Intelligence are. However, you may still learn a lot more about Artificial Intelligence and Data Science.

What is Deep Learning?

Machine learning is a subcategory of it. Deep learning, like machine learning, includes supervised, unsupervised, and reinforcement learning. As previously said, the human brain was the inspiration for AI. Let's try to connect the dots here: deep learning was inspired by artificial neural networks, which were inspired by human biological neural networks. Deep learning is one of the methods for putting machine learning into action.

Applications of Deep Learning and Machine Learning

Machine Learning and Deep Learning are widely employed in a variety of fields, including:

• Search engines, both text and picture searches, such as those used by Google, Amazon, Facebook, Linkedin, and others.
• Netflix utilises a recommendation system to suggest movies to viewers based on their interests, sentiment analysis, and photo tagging, among other things.
• Medical - cancer cell identification, restoration of brain MRI images, gene printing, and so on.
• Document - Super-resolution of historical document images and text segmentation in document images.
• Banks are in charge of stock forecasting and financial decisions.

Future Expectations of Deep Learning and Machine Learning

Both deep learning and machine learning have been on the rise for some time, and they are expected to continue for at least another decade. To increase income, industries are using deep learning and machine learning algorithms, and they are training their people to gain these skills and contribute to their company. Many startups are developing unique deep learning technologies that can address difficult challenges. Every day, groundbreaking research is being conducted not only in industry but also in academia, and the way deep learning is altering the world is simply mind-boggling. Deep learning architectures outperformed current methods by a significant margin and produced state-of-the-art results.

Deep learning and machine learning skills will almost certainly play a big part in the coming years in order to thrive in either industry or academia.

Difference between Deep Learning and Machine Learning 

1. Functioning -
   Deep learning is a subset of Machine Learning that takes data as an input and uses an artificial neural network stacked layer-wise to generate intuitive and intelligent conclusions. Machine learning, on the other hand, is a subset of deep learning that accepts data as an input, parses it, and attempts to make sense of it (decisions) based on what it has learnt during training.
    
2. Characteristic Extractor -
   Deep learning is thought to be a good way for extracting useful features from unstructured data. It does not rely on hand-crafted features such as local binary patterns, gradient histograms, or the like, and it extracts features in a hierarchical manner. It learns features layer by layer, which means that it learns low-level features in the first levels and then progresses up the hierarchy to learn a more abstract representation of the input. Machine learning, on the other hand, is not an effective tool for extracting significant features from data. To perform properly, it relies on hand-crafted features as an input.
    
3. Computation Power -
   Because deep learning networks are data-dependent, they require more than a CPU can provide. A graphical processing unit (GPU) with thousands of cores is required for deep learning network training, as opposed to a CPU with a few cores. Compute power is dependent not just on the amount of data, but also on how deep (big) your network is; as the amount of data or the number of layers grows, so does the amount of computation power required. A typical machine learning algorithm, on the other hand, may be implemented on a CPU with reasonable parameters.
    
4. Training and Inference Time:
   A deep learning network's training time might range from a few hours to several months. Yes, you read that correctly. Months of training are not uncommon. Training a network with more significant data takes time if you have a large amount of data. Furthermore, as the number of layers in your network grows, so does the number of parameters known as weights, resulting in delayed training. Not only may very deep neural networks take a long time to train, but they can also take a long time to infer since the input test data will run through all of the layers in your network, resulting in a lot of multiplication, which will take a long time. Traditional machine learning algorithms can train quickly, anywhere from a few minutes to a few hours, but other methods can take a long time to test.
    
5. Problem-solving Methods -
   To use machine learning to solve a problem, you must first break the problem into sections. Let's imagine you want to do object recognition. To do so, you must first scan the entire image to see if there is an object at each position and if so, where it is located." Then you use a machine learning technique, such as a support vector machine (SVM) with local binary patterns (LBP) as a feature extractor, to distinguish relevant objects from all the candidate objects. In deep learning, on the other hand, you provide the network the bounding box coordinates as well as all of the object's labels, and the network learns to localise and classify on its own."
    
6. Ready for Industry -
   It's usually simple to figure out how machine learning algorithms function. Deep learning algorithms, on the other hand, are a dark box in terms of what parameters it chose and why it chose those values. Even if deep learning algorithms can outperform people in terms of performance, they are still unreliable when it comes to industry deployment. Machine learning techniques such as linear regression, decision trees, random forest, and others are frequently utilised in businesses, with one example being stock predictions in the banking sector.
    
7. Output -
   A numerical number, such as a score or a classification, is usually the outcome of traditional machine learning. A deep learning method's output can be a score, an element, text, audio, and so on.
