Machine Learning

What is Machine Learning?

Machine learning is an important part of artificial intelligence (AI) where algorithms learn from data to better predict certain outcomes based on patterns that humans struggle to identify. 

What Kind of Outcomes Can Machine Learning Predict?

Machine learning can predict outcomes from a business perspective, such as which of your customers are likely to churn. It can also predict the likelihood of an insurance claim being fraudulent. The list of use cases for machine learning that can be applied to is vast and may appear to be too complex to comprehend quickly. However, the key element is identifying patterns with common results. 

Why is Machine Learning Important?

The answer to this question can be found by understanding what machine learning excels at. For instance, most statistical analysis relies on exact rule-based decision-making. Machine learning, on the other hand, thrives at tasks that are hard to define with step-by-step rules. This means that a business can apply machine learning strategies to business scenarios where the outcome is influenced by hundreds of factors that the human mind would struggle to compete with. 

Try to consider all the factors of why a person might default on a loan– it’s actually nearly impossible to hold all the potential reasons in your mind. By contrast, machine learning solutions can consider all factors at once and match them to patterns that better predict a default on a loan. On top of that, machine learning can apply multiple models in parallel to arrive at multiple potential solutions.

Machine Learning FAQs

What is the difference between Artificial Intelligence (AI) and machine learning?

Artificial intelligence is a technology that allows machines to simulate human behavior. Machine learning is a subset of AI technology that allows a machine to automatically learn from past data without programming explicitly for a use case.

What is the best programming language for machine learning?

Below is a list of common programming languages used for machine learning

  • Python (important note: Python leads all other programming languages and is being used by more than 60 percent of machine learning programmers)
  • Java
  • C++
  • R
  • Javascript

Why is machine learning the future?

Many answers can be given to this question, however, one of the biggest benefits of machine learning is its ability to quickly understand immense databases and provide valuable insights to users. Examples include: helping companies support cutting-edge cancer research, and inventory tracking for other companies.

What are examples of machine learning?

Below is a list of common applications that use machine learning:

  • Image recognition
  • Speech recognition
  • Medical diagnosis
  • Statistical arbitrage
  • Predictive analytics
  • Extraction

Is Al or ML better?

The answer to this question isn’t a simple “one is better than the other.” Consider the following to understand how they complement each other: AI has a wider range of scope than ML. AI is a result-oriented branch with a pre-installed intelligence system. However, AI is hollow without the learnings of ML. They complement each other to attain high-quality results.

Is machine learning a good career?

Machine learning is a career path you should consider if you’re interested in data, automation, and algorithms. The World Economic Forum stated that “AI, Machine Learning, and automation will power the creation of 97 million new jobs by 2025.”

What are the benefits of machine learning?

There are many benefits of machine learning. Below is a small sample of its many benefits:

  • Easily identifies trends and patterns
  • Continuous improvement
  • Handling multidimensional and multi-variety data

Where are Al and ML used?

AI and ML have many current applications. Below is a small list of some of its applications:

Does Alexa use Machine Learning?

Machine Learning vs Other Technologies & Methodologies

Machine learning vs artificial intelligence

Artificial intelligence is a technology that allows machines to simulate human behavior. Machine learning is a subset of AI technology that allows a machine to automatically learn from past data without programming explicitly.

Machine learning vs deep learning

Deep learning is a type of machine learning, which is a subset of artificial intelligence. Machine learning is about computers being able to think and act with less human intervention; deep learning is about computers learning to think using structures modeled on the human brain.

Machine learning vs data science

Data science is the field that studies data and how to extract meaning from it while machine learning focuses on tools and techniques for building models that can learn by themselves by using data.

Machine learning vs neural networks

Machine Learning is a set of algorithms that parses data, learns from the parsed data and uses those learnings to discover patterns of interest. Neural Networks, or Artificial Neural Networks, are one set of algorithms used in machine learning for modeling the data using graphs of Neurons.

Machine learning vs statistics

The difference between statistics and machine learning is that machine learning encompasses the convergence of a variety of techniques and technologies that may include statistics and statistical modeling, whereas statistics focuses on using data to make predictions and create models for analysis.

Machine learning vs data mining

Data mining is designed to extract the rules from large quantities of data, while machine learning teaches a computer how to learn and comprehend the given parameters. Or to put it another way, data mining is simply a method of researching to determine a particular outcome based on the total of the gathered data.

Machine learning vs algorithms

A traditional algorithm takes input and some logic in the form of code and produces output. A Machine Learning Algorithm takes an input and an output and gives the logic which can then be used to work with new input to give one an output. The logic generated is what makes it ML.
