Machine Learning: A Future AI Technology

Future Technology

Machine Learning is the Science that allows software applications to work on its own without being explicitly programmed thus enabling them to become accurate at predicting results. It is a way of programming the machines by using the historical data and based on that asking them to predict the new output values. It is the study of the computer algorithms that automates the analytical model building by improving automatically through the experience and by making use of the historical data.

The Machine Learning is perhaps the most interesting technology that has been developed which gives the computers the ability to learn. Machine Learning is a process that starts with feeding good quality historical data and then based on that data training the machines to predict outcomes based on similar kind of data. For training the machines, different machine learning models using different kind of data and algorithms are built. The algorithms are chosen based on what kind of task is to performed and what sort of data is to be made to work.

What is Machine Learning?

A branch of Artificial Intelligence and computer science that focuses on providing the computer systems with the ability to automate itself and learn and improve from its own experience without having the need to programme it explicitly is what is known as Machine Learning. It emphasizes on the development of the computer systems that once fed with an historical data can make future decisions without any external programming requirement. So, its simply that the computer systems can access the data and use it for learning on their own. The procedure of learning begins with feeding the system with some external data such as direct experience, instructions or observations so as to look for some pattern in that data and based on the pattern observed using it for making better decisions in the future. So, the main aim of the Machine Learning is to permit the computers to learn by itself without any human intervention and perform actions accordingly.

Importance of Machine Learning

Machine Learning is one of the most important subareas of the Artificial Intelligence. The concept of Machine Learning of making the computers get into an autonomous learning mode and to learn, grow, transform and develop by themselves without being explicitly programmed is what makes it a completely unique concept. The Machine Learning techniques have replaced the traditional statistical techniques of data extraction and interpretation works by making use of automated sets of generic methods. As of now, Machine Learning is used in several fields such as in the self-driven cars, in the online recommendation engines, in offering suggestions, in cyber fraud detection and many more. 

In all Machine Learning has made a market for itself and is continuously evolving. And with this continuous evolution comes the factor of rise in demand and importance. So basically, Machine Learning as a technology helps in analyzing bigger amounts of data thus easing the work of the data scientists in the automation process. This is the most prominent reason of Machine Learning gaining a lot of recognition, importance and prominence. 

Methods of Machine Learning

In Machine Learning, there are few algorithms based on which the machine is trained in such a way that it can perform the future actions. Classical Machine Learning categorizes the algorithms into four basic approaches for more accurate prediction results. The type of algorithm that data scientists use depends on the type of data that they want to predict. So, the algorithm types are as follows:

  1. Supervised Machine Learning algorithm:
    In Supervised Machine Learning algorithms, historical data is used to predict the results. Here the data that was used in the past is fed into the system and the system analyses that known dataset based on which the learning algorithm produces an inferred function for making prediction of the output values. The learning algorithm also compares the outputs with the intended output and discovers errors so as to modify the model accordingly. The system once sufficiently trained is able to provide targets for any input.
     
  2. Unsupervised Machine Learning algorithm:
    This type of algorithm is used to train model when the available data is neither classified nor labelled. So here the models are trained in such a way that it can infer a function and then describe a hidden pattern or structure from that unlabelled data. In this type, the system isn’t able to figure out the proper output but by exploring the data is capable in drawing inferences to describe the hidden structures in the datasets. 
  3. Semi-supervised Machine Learning algorithm:
    The semi-supervised Machine Learning algorithm is a blend of both the supervised and unsupervised machine learning algorithm. Here, a small amount of labelled data and large amount of unlabelled data are made use of for making the predictions. It is an algorithm that helps the system improve the learning accuracy as the acquired labelled data requires skilled resources for training the system whereas the unlabelled data doesn’t require any additional resources. So, a mixture of the two results in the system itself improving the learning accuracy. 
  4. Reinforcement Machine Learning algorithm:
    It is a slightly different learning algorithm wherein the system interacts with the environment by producing certain actions and based on that discovers errors or rewards. This procedure allows the machines and the data scientists to determine the ideal behavior automatically within a specific context so as to improve the performance and the efficiency. A simple reward feedback is required to chose which action is best and this is what is termed as reinforcement signal. Trial and error search and the delayed reward are some of the most popular characteristics of the reinforcement learning.

Why should you learn Machine Learning?

Machine Learning today has made its influence fell in almost all the industries. It today has got all the attention due to the fact that it can automate most of the tasks out of which the ability to imitate humans and perform accordingly is considered to be the best. Replicating the human intelligence to the machines is something that can be achieved only with the Machine Learning. Image recognition, text generation, bio-metrics detection, flaw detection and many more cases are finding the applications of the Machine Learning in real world.

Businesses now are able to automate most of their processes because of this technology. It also helps in automating and creating quick models for data analysis which can then process and analyze large sum of data to deliver accurate results. An additional advantage that Machine Learning provide is that these models created using Machine Learning are precise, scalable and function with very little turnaround time. Various industries are now making use of this technology as they are mostly dependent on vast quantities of data for their industrial operations and for intelligent decision making. So, Machine Learning provides the ease of performing all the tasks by building such precise learning models that their accuracy is way far better than what used to be earlier. Businesses can now easily avoid unknown risks and leverage upon profitable opportunities. So, all this creates an increased scope for Machine Learning experts to showcase their talent as a professional.

Working of Machine Learning

For making any Machine Learning model to work, some steps need to be followed which are Gathering Data, Preparing the Data, Choosing a model, Training, Evaluation, Hyper-parameter Training and Prediction.

The model is the system which when trained is asked to make predictions. The parameters are the factors based on which the model is able to make the predictions. The programmer makes certain adjustments such that the model aligns itself with the parameters in such a way that the predictions made by the model does match the actual result. Here the working of a Supervised Learning Machine Learning model is elaborated.

  1. So, the first step in making a model work is to collect some sample data.
  2. The next step is to classify the sample data based on certain parameters and then describe each of the classified data.
  3. This data is then fed into the system and the model is trained based on that sample dataset. Their may be few parameters or may be even thousand parameters on which the Machine Learning model is to be trained. 
  4. During all this process many errors may occur in the dataset so they are removed from the training set and then the anomaly free data is made use for training the model. 
  5. This is then followed by testing the dataset. A testing set is basically some other dataset on which the trained model is made to work and if the result matches the expected output, then the model is declared as successfully trained and tested model and can now be made to predict results for similar databases.

Machine Learning algorithm is used for building intelligent systems that can learn from their past experiences and based on that modify itself to deliver accurate results. Many industries are thus making away toward the Machine Learning solutions to boost their profits and also to create newer and better products and services for the customers. So, all this gradually is resulting in creation of more jobs in the Machine Learning field. And as the demand is increasing it results in more pay scale too.

Coding: Roadmap For Beginners

          Coding is basically a process used for creating software instructions for computers using various programming languages. With the help of computer coding, we can program websites, apps and various other technologies that we interact with in our everyday life. In coding we use several languages to give a computer instruction based on which specific functions are performed by the programmed machines. There are various types of codes and each code has its specific function and then depending on what is to be developed the codes are programmed for those machines. All the popular technologies that we have today like Facebook, Instagram, Electric Vehicle, Robots, Smartphones, Browsers are all developed using some specific code.

Difference: Programmer and Coder

     Since we are a piece of the computerized time, you may have run over the two terms, coding and programming, utilized reciprocally. It is a typical idea that coders and programmers are almost the same things. Actually, there is such a lot of distinction between computer programming and coding according to the product improvement jargon.

Compiler: A Digital Conveter

A Compiler is a computer-based program that translates coding statements or code written in one programming language to another programming language that the computer processor can understand. It is a computer software that compiles a source code written in a higher-level language like C, C++, Java, etc. into a set of programming instructions or lower-level language that can be understood by the computer’s processor and based on which then various functions are carried out by the digital machine. Compilers are very large programs with the ability of error-checking and various other functions. Some compilers compile high- level language into low level language directly but then there are some compilers that translate higher-level language into an intermediate assembly language and then this intermediate language using some set of assembly programs or assembler is compiled into lower-level language or machine code.
