What is Machine Learning?

Introduction to Machine Learning

Hey, what is Machine Learning? This whole blog talks about Machine Learning, what is Machine Learning Model and its respective modules. Machine Learning is one of the top-rated and commanding technologies in today’s IT world. We can also say Machine Learning is a core sub-area of AI (Artificial Intelligence).

There are many people who are not much aware of the importance of Machine learning, how machine learning works and its features. Computational science is very much involved in the Machine Learning model which mainly focuses on interpreting patterns, examining the data structures, decision making and reasoning that are not with human interaction.

The predictable future is expected to have a great impact on the Machine Learning language. Transformation of data and information to knowledge is perfectly possible through a tool called Machine learning is a tool for turning information into knowledge. We can experience a burst of data available in the past 50 years in all categories. If we are not able to analyze and perform research on the data pattern, the whole bunch of data becomes useless.

1. What is Machine Learning

Over View of Machine LearningMachine learning is the concept of using the different sample data model to create a mathematical model to understand the specific task. As machine learning deals with business problems the other name for machine learning is predictive analysis. The Supervised machine learning algorithm, unsupervised algorithm, Semi-supervised algorithm, and reinforcement machine learning algorithm are the algorithms of machine learning which are used to make the computers to learn by experience.

A list of Machine learning techniques is available mechanically to retrieve the treasured fundamental patterns from complicated data. It is possible to face some obstacles while discovering the challenges in data without the Machine Learning model. For a better and enhanced decision making, we can make use of these discovered patterns and data knowledge to know about a problem and give some predictions on the future. It is obvious that every single day we are interacting with one or other Machine Learning concepts.

Browsing through Google, listen to music, clicking a picture are some of the incidents that we face with Machine Learning. With Machine Learning, there are few advance changes like producing fresh drugs, cancer detection, and self-driving cars. Going forward, we are planning have some discussion on why to use Machine Learning, the difference between Deep Learning and Machine Learning, Different Types of Algorithms, Future of Machine Learning, available job opportunities, and package.

2. Why Use Machine Learning?

With the help of Machine Learning language, you can make your system learn many important factors from different experiences and incidences to see progressions in decision making capability and skillsets. Apart from the advantages like managing a large amount of data, we need to know the answer for a query “Why Machine Learning?”. So, below are the effective points to consider when looking for the benefits of Machine Learning language.

2.1 Expands the Accuracy of Financial Models and Rules:

Machine Learning is playing a significant role in the finance sector. The common benefits of Machine learning in the Finance sector are algorithmic trading, portfolio management, fraud detection, and loan underwriting. It is possible to perform data assessments to analyze and detect gradation and irregularities. These are some of the points which show the accuracy of financial rules and models.

2.2 Healthier Customer Division and Precise Lifetime Value Forecast:

In today’s trend, one of the most challenging parts of the marketers is the customer division and lifetime value estimate. Numerous data from different channels are distributed to the marketing and sales team like lead data, email campaigns, and website visitors. ML is very helpful in predicting discrete marketing offers and enticements.

2.3 Shortens Product Marketing and Aiding in Exact Sales Prediction:

There are multiple benefits to promote a product using Machine Learning. As ML has a huge amount of data, these data can be utilized to alter and review the marketing and sales strategies as per the client’s behavioral design. This will enable the customers to see the right data at the right time without wasting labor time. Even the past behaviors of data and their resolutions can be analyzed with ML.

2.4 Simple Detection of Spam:

Detection of spam was a big issue in earlier days, which got solved very easily in the current days using Machine Learning. To filter the spam, rule-based techniques were used in the earlier days by Email providers. A neural network is the new type of brain technique used for filtering the spam with the help of ML. There are many rules designed across various computer networks and neural networks are good at recognizing the junk mail and phishing messages by evaluating those designed rules.

2.5 Endorsing the Correct Product:

Endorsing a product is not a simple task in this highly competitive market. Machine Learning sounds good in providing product recommendations to enhance the marketing and sales strategy. Based on the purchase history and product identity, data analysis is done with ML. An algorithm is created to identify the hidden patterns within various products and group the similar purchased products into a single cluster. This type of algorithm is known as unsupervised learning.

4. Types of Machine Learning

Machine Learning is available all around the world and we all are experiencing any one of the occurrences every day. A new method of data is arising from using Machine Learning. As there are few complexities seen in Machine Learning, it is divided into two main areas called supervised and unsupervised learning. Each type has its own advantages and different working process.

70% of Machine Learning is said to be supervised learning and we can expect only 10 to 20 percent as unsupervised learning. Apart from these two, we have another type called reinforcement learning. Now, let us discuss all three Machine Learning types and know the entire knowledge.

4.1 Supervised Learning

Labeled or known data are used for processing data in supervised learning. As we use known data for a data process, such type of learning is called supervised learning. A Machine Learning Algorithm is designed through which data travel and helping to train the model.

When the model training is over, unknown data can come into the picture for us and receive a fresh response. Some of the best algorithms used in supervised learning are Decision trees, Naïve Bayes, Random forest, Polynomial regression, and Linear regression.

4.2 Unsupervised Learning

Usage of unknown or unlabelled training data is happening in unsupervised learning. This means, the data is very fresh and not visited by anyone before. As the unknown data is used, none of the algorithms can be applied to the inputs and hence we can experience some unsupervised terms originating. The entire data is pushed into a Machine Learning algorithm which is helpful in training the model.

The trained model performs a hunt for a better pattern and provides the necessary response. For unsupervised learning, the algorithms used are Fuzzy means, Apriori, K-means clustering, Partial least squares, Hierarchical clustering, and Singular value decomposition.

4.3 Reinforcement Learning

Like a traditional method of data analysis, we have the algorithm that discovers data via trial and error process, later which results in greater rewards. Actions, agent, and environment are the major components of reinforcement learning. Decision-makers are called agents, everything through which agents interact is called environment, and all the actions performed by the agents are referred to actions here.

When an agent makes a choice of action to increase the expected reward for a specified duration, reinforcement learning happens.

6. Machine Learning Models

The models of machine learning are used to reach the level of accuracy and it applies the mathematical concepts towards real-world problems. The input, output, and models are analyzed to give precise predictions. Let us provide some key models of machine learning.

Machine Learning Models

6.1 Artificial Neural Networks

Artificial neurons are signal transmitters that create a connection like the human brain. The connection between two neurons is called as edges and the weight between edges increases or decreases as per the strength of the connection. The model of the ANN approach is developed to duplicate the work of the human brain. The transformation of light into vision and sound into hearing is the work of the brain. Deep learning is the other concept under neural networks which consist of many hidden layers. Speech recognition and computer vision of deep learning are designed like the human brain which became successful.

6.2 Decision trees

Decision trees are predictive modeling to get conclusions to the problem and this is used in subjects like data mining, statistics, and machine learning. Leaves of the tree structure show the class labels and the branches represent the features conjunction that leads or group the labels.

6.3 Support vector machines

SVM is one of the supervised learning methods to identify whether examples used for training falls under one or two categories. SVM performs linear and non-linear classification with high dimensional features of examples.

6.4 Regression analysis

The given data is used along with statistical methods to understand the connectivity among the input variable and the features of the input variable is called a regression analysis. Line or square is drawn to understand the data in mathematical form.

6.5 Bayesian networks

The Bayesian network uses the acyclic graph to represent a set of random variables as a joint probability distribution. The Bayesian network is used to develop a model for the data or extract expert opinion from the given data.

7. Phases of Machine Learning Algorithm

Machine Learning Algorithm is divided into two main phases which are Training Phase and Training Phase.

7.1 Training Phase

Let us discuss the Training phase with an outstanding example. Pick few apples from the market and create a table to list out the physical characteristics of each apple such as size, color, the country to which each apple belongs, shape, vendor name, etc. These characteristics are named as training data. And now list out the outcome of those apples like juiciness, taste, sweetness, ripeness, etc and these are named as output variables. Now all these data altogether must be pushed into the Machine Learning algorithm which is classification and regression. This process learns a correlation model between its excellence and physical characteristics.

7.2 Testing Phase

Let us continue to have an example to explain the Testing Phase. Again, when you are shopping for the apples, you will attempt to get the apple’s characteristics measure that you purchase. This is called test data. The next step is feeding the retrieved test data to the Machine Learning algorithm. Now, the algorithm will use the previous model that you used to compute in the Training phase. Internally, rules may be used by the algorithms. Finally, it is a good chance to purchase good apples with full confidence while shopping as you are aware of the entire apple details.

8. Applications of Machine Learning

Netflix, wall street journal and sun microsystems are some of the companies which make use of machine learning as a recommendation algorithm and diagnostic software. Let us detail some of the applications of machine learning to understand how it supports different processes.

Applications of Machine Learning

IBM Watson Genomics is the application of machine learning which is used to make a diagnosis of the tumor. Manufacturing drug, image diagnosis, maintaining health records, data collection and predictions are some of the applications used in the healthcare industry promoted using machine learning techniques.

8.2 Finance

Machine learning is the branch of data science that uses models for analyzing financial data. Agility is the major factor that says that data infrastructure in the finance industry is not ready for analysis. Process automation, Chabot usage, automation in call center work, detecting fraud, improving security, portfolio advisory from robots, and marketing with targeted customers are some of the benefits of machine learning in the finance industry.

8.3 Virtual personal assistants

Machine learning is used for different types of virtual assistants like creating text messages, finding the status of the flight, show directions for particular location, find the location of hotel, request song, handle the phone calls and make phone calls, handle the calendar with organized events, and request for particular song as per commands.

Examples of such virtual assistants incorporated with devices are seen with Google and Alexa. Speech recognition, voice recognition, and image recognition are moving the demand of these virtual assistants.
