Definition of Artificial Intelligence

Artificial Intelligence refers to intelligence displayed by machines that simulate human and animal intelligence.

Data Economy

Let us quickly understand the importance of Data in brief.

  • The world is witnessing the real-time flow of all types of structured and unstructured data from social media, communication, transportation, sensors, and devices.
  • International Data Corporation (IDC) forecasts that 180 zettabytes of data will be generated by 2025.
  • This explosion of data has given rise to a new economy known as the Data Economy.
  • Data is the new oil that is precious but useful only when cleaned and processed.
  • There is a constant battle for ownership of data between enterprises to derive benefits from it.

The Emergence of Artificial Intelligence

The data economy with its vast reservoir is enabling unprecedented innovation in data sciences, the field which deals with extracting useful information and insights from the available data.

Data science is going toward a new paradigm where one can teach machines to learn from data and derive a variety of useful insights. This is known as Artificial Intelligence.

Artificial Intelligence in Practice

Given below in this Machine Learning tutorial are a few areas where AI is used widely.

  • Self-driving cars
  • Applications like Siri that understand and respond to human speech
  • Google’s AlphaGo AI has defeated many Go champions such as Ke Jie
  • Implementing AI in chess
  • Amazon ECHO product (home control chatbot device)
  • Hilton using Connie – concierge robot from IBM Watson

Data Facilitates Artificial Intelligence Products

Amazon pulls in data from its user database to recommend products to users. This functionality helps bring in more users. More users generate even more data that help enhance the recommendations even further.

What is Machine Learning?

The capability of Artificial Intelligence systems to learn by extracting patterns from data is known as Machine Learning.

Machine Learning Benefits

Let us look at some of the benefits in this Machine Learning tutorial.

  • Powerful Processing
  • Better Decision Making & Prediction
  • Quicker Processing
  • Accurate
  • Affordable Data Management
  • Inexpensive
  • Analyzing Complex Big Data

Features of Machine Learning

Let us look at some of the features given below in this Machine Learning tutorial.

  • Machine Learning is computing-intensive and generally requires a large amount of training data.
  • It involves repetitive training to improve the learning and decision making of algorithms.
  • As more data gets added, Machine Learning training can be automated for learning new data patterns and adapting its algorithm.

Example: Learning from new spam words or new speech (also called incremental learning)

Artificial Intelligence and Machine Learning

Machine Learning is an approach or subset of Artificial Intelligence that is based on the idea that machines can be given access to data along with the ability to learn from it.

Traditional Programming vs. Machine Learning Approach

Given below is an overview of Traditional Vs Machine Learning.

Traditional programming relies on hard-coded rules.

Machine Learning relies on learning patterns based on sample data.

As you go from rule-based systems to the deep learning ones, more complex features and input-output relationships become learnable.

The Relationship between Data Science and Machine Learning

Let us understand the relationship between Data Science and Machine Learning.

  • Data Science and Machine Learning go hand in hand. Data Science helps evaluate data for Machine Learning algorithms
  • Data science is the use of statistical methods to find patterns in the data.
  • Statistical machine learning uses the same math and techniques as data science.
  • These techniques are integrated into algorithms that learn and improve on their own.
  • Machine Learning facilitates Artificial Intelligence as it enables machines to learn from the patterns in data.

Machine Learning Techniques

Given below are some techniques in this Machine Learning tutorial.

  1. Classification
  2. Categorization
  3. Clustering
  4. Trend analysis
  5. Anomaly detection
  6. Visualization
  7. Decision making

Machine Learning Algorithms

Let us understand Machine Learning Algorithms in detail.

  • Machine Learning can learn from labeled data (known as supervised learning) or unlabelled data (known as unsupervised learning).
  • Machine Learning algorithms involving unlabelled data, or unsupervised learning, are more complicated than those with the labeled data or supervised learning
  • Machine Learning algorithms can be used to make decisions in subjective areas as well.


  • Logistic Regression can be used to predict which party will win at the ballots.
  • Naïve Bayes algorithm can separate valid emails from spam.
