Today, machine learning systems are considered powerful tools for solving many complex classification problems. But, as these systems continue to evolve, there will be a huge demand for smarter languages that can process a number of general paradigms and complex issues, a few of which may be quite complicated to process for humans. In simple, a machine-learning language is defined as a language that can process a complex machine learning task.
As the industry’s experience with smart machine learning systems is growing day by day, the entire machine learning field is being staged to shift from solving a simple problem to the creation of complex and powerful algorithms that operate based on an advanced level.
Having said that, a number of machine learning languages that can deal with complex problems (as said earlier in this section) have paved the way for the future of artificial intelligence and integration. Some of the top machine learning languages are MATLAB/Octave, Python, Java/C-family, ELM (Extreme Learning Machines), and R.
Machine learning system consists of 3 major components. They are the model, parameters, and the learner. A model is a system that makes identifications or predictions. Parameters are the factors or signals that the model uses to form its decisions. A learner is a system that adjusts the model (by adjusting the parameters) by observing the differences in actual outcome versus predictions.
The working of machine learning begins with the model. Initially, you have to give the model ( a prediction) to the system. The model depends on parameters utilized to make its calculations. The machine learning system uses a mathematical equation for expressing the parameters, to efficiently form a trend line of what actually is expected. So, real-life information is entered once the model is set. Most times, the real scores don’t match the model; some may be below or above the predicted line. Now, the learning component of machine learning begins.
The real-life information that is given to the machine learning system is known as the training data or training set as it is utilized by the learner present in the machine learning system for training itself in order to create a better model. The learner observes the scores and determines the difference between them and the model. Then, it uses math for adjusting the initial assumptions. Now, with a new set of scores, the system is run again.
After this, the comparison is done between the revised model by the learner and the real scores. If successful, the scores will be much closer to the prediction than the previous one. However, these won’t e ideal. So, the parameters have to be again adjusted by the learner for reshaping the model. You have to input another test data set and a comparison will happen again. Now, the learner will adjust the model again. This is a cycle that keeps repeating till the model correctly predicts the outcome.
The machine learning system will make adjustments again and again in this manner till it gets things right. This is known as gradient learning or gradient descent. This is how a machine learning system works.
Machine learning has numerous uses in many sectors. Let’s have a look at them.
Machine learning and AI are often used interchangeably, mainly in the realm of big data. However, these aren’t the same and it’s important you understand the difference between them. Artificial Intelligence is a branch within the computer science field and can be defined as the ability of a machine or a computer program to learn from experience and perform tasks in the same way as humans. Now, let’s understand the differences between AI and Machine Learning from the below table.

In order to break down a real problem and to develop a machine learning system to tackle it, you should get to know the types of machine learning algorithms. In this section, we will list out the types of machine learning algorithms and have a good understanding of each one of them.
[ Note: Labeled data: Labeled data is known as the data that contains a set of training examples, and each example is a pair that consists of the desired output value (also known as labels, supervisory signal, etc.) and an input value.]
The supervised machine learning algorithm contains an outcome/target variable (or a dependent variable) that has to be predicted from a given independent variable set. A function that maps the inputs to desired outputs can be generated with this set of variables.
We don’t have any outcome or target variable for estimating/predicting, in this algorithm. So, we do not tell the system where to go. Instead, the system has to understand where to go from the data we provide to it. The unsupervised machine learning algorithms utilize techniques on input data to detect patterns, mine for rules, and group and summarize the data points that help in deriving meaningful insights and describe data to the users in a much better way.
Unsupervised algorithms are used mainly in descriptive modeling and pattern detection. These algorithms are mainly used in instances where human experts don’t know what to look for in data. Examples of unsupervised learning include K-means, Apriori algorithm, etc.
In the previous two machine learning algorithms, either the labels are present for all the observations or there are no variables for all the observations. The semi-supervised machine falls in between unsupervised and supervised machine learning, i.e., it uses both unlabeled and labeled data. Accuracy can be improved significantly with this learning as we can use a small amount of labeled data along with unlabeled data in the train set. The examples include Transductive Support Vector Machine (TSVM), label propagation, etc.
We don’t have any unlabeled or labeled datasets in reinforcement learning, and, so, it’s not like any of the three previous algorithms. It works in a way that the machine is subjected to an environment where it continuously trains itself using trial and error.
The machine is trained to take accurate business decisions by learning from previous experience and capturing the best possible knowledge. Reinforcement learning is a really complex and powerful algorithm to apply for problems. Examples of reinforcement learning include Q-learning, Deep Q Network (DQN), Markov Decision Process, etc.
Supervised algorithms are used for predicting continuous values (classification) and discrete values (regression). Supervised learning is accurate and very fast. Examples of supervised machine learning algorithms include Naive Bayes, Linear Regression, Nearest Neighbor, Neural Networks, Support Vector Machines, etc.

It’s a fact that no one machine learning algorithm can solve every problem. For example, you can’t say that decision trees are always better than neural networks and vice-versa. Many factors like the structure and size of your dataset will play a crucial role in determining the most suitable algorithm for a given problem. Having said that, let’s talk about the top machine learning algorithms used by data scientists.
[ Related Article: Top Machine Learning Frameworks ]
A Naive Bayes Classifier can be defined as a probabilistic machine learning model utilized for tasks related to classification. This is a supervised machine learning algorithm and represents a statistical method for classification. This algorithm can solve predictive and diagnostic problems. Naive Bayes Classifier is based on the Bayes theorem. The Bayes Theorem is represented below.
Given that B has occurred, we can find the probability of A using the Bayes Theorem. Here, A is the hypothesis and B is the evidence. The features/predictors are independent is the assumption made here.
K-Means Clustering is an unsupervised machine learning algorithm and is utilized when you have unlabeled data. The algorithm locates the groups in the data while the K variable represents the number of groups. The algorithm works in an iterative manner for assigning each data point to one among the K number of groups depending on the features that are provided. Depending on feature similarity, the data points are clustered. Some examples of use cases are behavioral segmentation, sorting sensor measurements, inventory categorization, etc.
A support vector machine (SVM) is a supervised machine learning algorithm and based on the decision plane concept that defines decision boundaries. A decision plane separates between object sets consisting of different class memberships as shown in the below image. Two classes, Green and Red, are considered here.
The separating line is defined as the boundary and all the objects to its left are Red and the ones to its right are Green. Any new object is classified or labeled as Green when it falls to the right. This one is an example of a linear classifier (a classifier that separates a set of objects into different groups (Red and Green in this case)).
SVM is commonly employed for regression and classification purposes.
The Apriori algorithm operates on database records, especially on records including certain numbers of fields or items, or transactional records. It uses a bottom-up approach for incrementally contrasting complex records and is quite useful in complex AI and machine learning projects. The Apriori algorithm contrasts or scores each component of a larger dataset with other sets in some ordered manner. The resulting scores are utilized for the generation of sets that are classified as frequent appearances in a larger database for the purpose of aggregated data collection. One practical use case of this algorithm is the market basket tool.
A method of modeling a target value depending on independent predictors is known as regression. Linear regression is a method used for the prediction of the dependent variable (Y) based on the independent variables’ values (X). This algorithm is used in instances where we should predict some continuous quantity. The use cases of this algorithm include predicting traffic in a retail store, the number of pages visited on mindmajix.com, etc.
The logistic regression algorithm is utilized for classification tasks. This algorithm utilizes a linear equation with independent predictors for predicting a value. The value that is predicted can be anywhere between positive infinity and negative infinity. We require the algorithm’s output to be in the form of a class variable (i.e., 1-yes, 0-no). So, we squash the linear equation’s output into the range of [0,1]. We use the sigmoid function for squashing the predicted value between 0 and 1. The below images depict the linear equation (a) and sigmoid function (b).
The use cases of this algorithm include classifying whether a tumor is benign or malignant, classifying whether an email is a spam or not, etc.
It’s a well-known fact that our brains interpret the context of real-world situations in a way that’s not possible for computers. An artificial neural network (ANN) is a simulation of the neural networks that make up a human brain so that the computer can interpret things and make decisions just like humans do. Conventional computers are programmed to behave like interconnected brain cells and, this way, artificial neural networks are created.
ANNs utilize different layers of mathematical processing for making sense of data it is fed. A simple neural network consists of 3 layers and is represented in the below image.

Random Forest is a flexible supervised machine learning algorithm. It is very easy to use and, most of the time, it yields great results, even in the absence of hyper-parameter tuning. It creates a forest and makes it random as you can view from its name. The forest here is a group of decision trees trained with the bagging method most of the time.
The idea behind the bagging method is that a combination of learning models improves the overall result. Thus, a random forest develops multiple decision trees and merges them to acquire a more stable and accurate prediction. Random Forest algorithm can be used for both regression and classification problems. An image that depicts a random forest with two trees is given below.
The use cases of this algorithm include the stock market, banking, e-commerce, medicine, etc.
A Decision tree is a supervised machine-learning algorithm and can be used for both classification and regression problems. The goal of the decision tree algorithm is to create a training model which can be used to predict the target variables’ value or class by learning decision rules inferred from training data (prior data).
This algorithm uses a tree representation to solve a given problem. Each leaf of the tree represents a class label, each branch represents a decision, and each internal node represents an attribute. So, a tree is created for the entire data and a single outcome is processed at every leaf. The decision trees are easy to understand and less data cleaning is required. Examples include IBM SPSS Modeler, SAS Enterprise Miner, Salford Systems CART, etc.
The K-Nearest Neighbors algorithm is a supervised machine learning algorithm and can be used for both regression and classification problems. However, it is most widely used for classification problems. The output of KNN depends on whether it’s used for regression or classification. The output is a class membership in KNN classification and the property value for the object in KNN regression.
Here, k represents a small positive integer and is assigned to the class of a single nearest neighbor. It is a non-parametric algorithm, i.e., it doesn’t make any underlying assumptions about data distribution. We are given some training data here, and it classifies coordinates into various groups identified by an attribute. KNN is a simple algorithm but yields high competitive results. The use cases of this algorithm include pattern recognition, recommender systems, concept search, etc.
The demand for machine learning experts has witnessed rapid growth in recent years. You must gain knowledge of certain programming languages to work in this field.

The use of machine learning is implemented across the world and it is not limited to the following:
Based on your buying pattern if the system observes any uncertainty it quickly alerts the authorities and at the same time intimates the user.
The best example is your Gmail account login. If you have logged into your Gmail account from a different city or country or logged into your Gmail account from a new device, immediately you will get an email to your account. This means your regular device and the internet connection is been logged somewhere and a system is monitoring for uncertainties.
All your search results are tracked and based on your search history pattern, real-time ads are displayed on the web browsers.
For example: If you have searched for any Televisions on Amazon and closed your browser and then started browsing or reading something over the internet, TV-related ads will be shown in the browser prompting the user to buy.
The best example of this is your Gmail app on your iPhone or your Android phone. If you have the latest app updated on your phone, whenever a user reads the email, predefined options are displayed for the user to reply back. This way the user doesn’t have to manually type. This is one such example where the email is read by the system already and it has come to certain conclusions and the keywords are displayed for the user.
A lot of software companies have built a product using text-based sentiment analysis concepts and minting money on these products. Once the product is utilized by companies they can understand their customer’s reviews and comments.
