Here in this machine learning guide, we will be taking a tour all about machine learning understanding its A-Z. So, let’s get started-
What is Machine Learning?
Introduction to machine learning is basically a mechanism of teaching a computer system to make accurate predictions when filled with data.
These computers are hence capable of identifying, analyzing, changing the information as per the requirements accordingly eliminating the need for human interactions.
The machine learning algorithms, its mechanism, and the power behind machine learning is self-identification and analyzing new patterns involved in complex pattern recognition algorithms.
Clubbing it all together, Machine learning is basically a mechanism streamlining the complex process into a meaningful one. The educational system, industries, pharmaceutical, science & space, maps, navigation, digital inventions- you name the domain and there is nothing left machine learning hasn’t taken part in. This is the reason, the maximum number of organizations are investing in machine learning development.
Timeline of Machine Learning
Machine Learning is not new, it was the invention made way back. Starting from Voice-activated home appliances, self-driving cars, online marketing to healthcare, Machine learning is benefiting us every other day.
Starting from mathematicians to great thinkers and scholars were involved in the foundation of how to start machine learning.
Here is how machine learning has evolved-
Great Evolution of Machine Learning
1812-1913- Foundation of Machine Learning
It is the mathematical foundation that laid the foundation for machine learning. The Bayes theorem & Markov’s Chains gave birth to innovation.
Late 1940s- Introduction of First computers
Computers are still known as a machine that can store trillions of data. The very popular Manchester Small- Scale Experimental Machine (widely known as Manchester Baby’) is the presentation of this era.
1950- The birth of Machine Learning
Before 1950, there was a lot of research and theoretical studies made for Machine learning, but the year 1950- is marked as the real birth of machine learning.
Alan Turing, the famous mathematician, researcher, computer genius, and a thinker, submitted a paper called “imitation game” and made the world astonished.
1951- First Neural Network
The very first neural network was made by Marvin Minsky with Dean Edmonds in 1951. Neural networks connect the thinking process of machines and computers.
1974- Naming of Machine Learning
It was 1974, the year coined the name for machine learning from the proposed words like Informatics, computational intelligence, and artificial intelligence.
1996- Game Changer
2006-2017- the year of Backpropagation, External Memory Access and AlphaGo
Back Propagation is the technique that is used for the machine for image recognition.
Also, Neural Network developed by DeepMind– A British based company. The network can access external memory and get things done.
ML with the support of AI is entering our personal lives helping through voice-activated devices, smart systems, automated systems, and more. This is called singularity which is doing to make an impact in the life of individuals.
Types of Machine Learning
Types of machine learning are basically divided into different sections-
- Supervised Learning
- Unsupervised Learning
- Semi-Supervised Learning
A. Regression Algorithm
- Linear Regression
- Logistic Regression
B. Decision Tree Algorithm
C. Artificial Neural Network
D. Support Vector Machine
Let’s discuss them in detail-
One of the most important and popular algorithms of AI is Learning Algorithms. When we say what is machine learning used for, these algorithms are easily adaptable to the problem environment. Also, these algorithms are divided into certain sections known as-
- Supervised Learning Algorithms
- Unsupervised Learning Algorithms
- Semi-supervised Learning Algorithms
Supervised Learning Algorithms
Supervised Learning is learning about a function that is appropriate for a particular problem.
The function takes input from (X) and maps it as output to (Y). The equation somewhere looks like Y= f(X). Furthermore, Dataset is split into 2 groups- Training Dataset and Testing/Validation Dataset.
Supervised learning problems then grouped them into classification problems and regression problems. In classification problem- Output is categorized into a specific group and Regression Problems are all about an output with real value.
Unsupervised Learning caters to the input dataset which is not labeled, Classified, or categorized. The mathematical model integrated into it helps in identifying similarity in the dataset while deducing a structure presented in the input data.
Furthermore, Unsupervised Learning Problems are grouped into clustering problems and association problems.
Semi-supervised Learning Algorithms
Semi-supervised Learning and input dataset is a combination of both Labeled data and unlabeled data. This dataset carries a small amount of labeled data along with a large amount of data.
Moving on, the mathematical model makes use of labeled data in order to learn the structure of unlabeled data for predictions.
Similarity Algorithms, one of the machine learning algorithms are classified as per the similarity of their functionality.
A. Regression Algorithm
Because of the relationship between variables, Statistical Machine Learning co-opted regression methods. Regression algorithms can refine the relationships between in order to predict a better outcome.
The algorithm is further divided into-
I. Linear Regression – This Regression is in the use from the last 200 years for removing variables from correlates. Also, the regression is used for removing noisy data from the dataset.
II. Logistic Regression– Logistic regression is majorly used for binary classification problems. The reason for using it is to get weights of input variables separately whereas the output is used for nonlinear function.
B. Decision Tree Algorithm
Just like a beginners guide to natural language processing is all about processing the language, similarly, the machine learning algorithm is meant for constructing a model of a decision fully based on the input variables. Decision tree mimics a binary tree, where each decision node is a single input variable. Also, these given nodes are then split into leaf-like nodes. And each leaf node is decked with output variables concerning the previously made nodes.
C. Artificial Neural Network
Also known as the Connectist system, ANN works like the brain’s neural network. Artificial Neural Networks is a framework made from various machine learning algorithms working together for processing the complete dataset.
The ANN is broadly divided into 3 layers- the input layer, hidden layers, and the output layers. Hidden layers are further categorized into multiple layers. Each layer of it is a collection of nodes known as artificial neurons.
Furthermore, these artificial neurons connect to the artificial neural present in the coming layer. The connection made between neurons is called edges.
The edges are important for transmitting information as a signal from one neuron to the next one.
D. Support Vector Machine
The next point in this machine learning guide is Support Vector Machine (SVM). The SVM mechanism is related to the supervised learning approach and is meant for classifying and regression.
Reinforcement Learning is the next required part of the machine learning tutorial. It is a subfield of machine learning known as approximate dynamic programming or neurodynamic programming.
Markov Decision Process (MDP)is the mechanism of the Reinforcement Learning ecosystem.
To understand machine learning algorithms, let us take an example.
Suppose, a child is sitting in a room and sees a fireplace in the room and tries to approach that fire. He feels the warmth of it and finds it positive. This makes him realize that fire is a positive thing. But when a child touches it, the fire burns the child’s hand. This made him realize that fire is a good thing to a certain extent. This is how reinforcement learning understands and learns from the actions made.
With the types covered, let us now check out how Machine Learning works in the next section of our machine learning guide.
