Machine learning overview, definition, tools, applications, advantages & disadvantages
Machine Learning is used in many applications such as banking & financial sector, healthcare, retail, publishing & social media, robot locomotion, game playing, etc, It is used by Google and Facebook to push relevant advertisements based on users past search behavior, Source programs such as Rapidminer helps in increasing usability of algorithms for various applications.
What is machine learning?
Machine learning works on the concept that a computer can learn information without human mediation, the computer learns how to decipher information as it has been labeled by humans, machine learning is a program that teaches from a model of data sets with human tags, It is a subfield of computer science & a specific application of data science that involves deploying algorithms to provide a computer, a software program, or a process with the ability to learn without being explicitly programmed.
Machine learning is the data analysis technique that teaches computers to do what is natural for humans and animals, Automatic learning algorithms find natural patterns in data that provide insight and help you make better decisions & forecasts, It is a set of programming tools for working with data, and deep learning, amplification is a subset of machine learning.
Machine learning is a general term for defining different algorithms of learning that generate quasi, It is the study of algorithms capable of classifying information they have never seen before by learning patterns of similar information, automatic learning deals with the design & development of algorithms to enable computers to develop behaviors based on empirical data, such as sensor or database data.
Matlab is an ideal environment to apply machine learning to your data analysis with the tools & functions, you need to manage large amounts of data, as well as applications to enable automatic learning, Integrate machine learning models into enterprise systems, clusters and clouds, and target models with embedded real-time hardware.
There are unlimited machine learning applications, Automatic learning becomes important for business operations, Different processes, techniques & methods can be applied to one or more types of algorithms for automatic learning to improve their performance, Function-learning algorithms (also known as representational algorithms) preserve information in their inputs, and transform it in a useful way, often as a pre-processing phase before classification or forecasting.
Functional learning is motivated by the fact that automatic learning tasks such as classification require mathematical & computationally useful input, based machine learning is a general term for any method of machine learning that identifies, teaches or develops rules for storing, manipulating or applying knowledge, Machine learning can be used to achieve higher levels of efficiency, It is based on the ability to use computers to probe data for structures.
When we write the code for some computing or embedded system it does what has been asked or mentioned in the code to do, The system neither takes any extra decisions nor performs any extra tasks, But machine learning based system is opposite to this, It learns itself based on the previous set of data as well as a new set of data and performs tasks which have not programmed by the programmer, This type of system is called as machine learning.
Machine Learning uses advanced models based algorithms to take decisions based on learning, The typical models include predictive models and neural network based models, These models develop decision trees which help the system take new decisions, In machine learning without supervision, the machine can understand & deduce patterns from data without human intervention.
Advantages of Machine Learning
Machine Learning can handle multi-dimensional and multi-variety data in dynamic or uncertain environments, It allows time cycle reduction and efficient utilization of resources, Due to machine learning there are tools available to offer continuous quality improvement in large & complex process environments.
Machine learning can review data & discover specific trends and patterns that would not be apparent to humans, for an e-commerce website like Amazon, it can understand the browsing behaviors and purchase histories of its users to help cater to the right products, deals, and reminders relevant to them, It uses the results to reveal relevant advertisements to them.
Machine Learning offers wide applications, It holds the capability to help deliver a much more personal experience to customers while also targeting the right customers, There is no human intervention needed (automation), with Machine learning helps make predictions and improve the algorithms, such as anti-virus software that learns to filter new threats as it is recognized, Machine learning is good at recognizing spam.
As Machine Learning algorithms gain experience, they keep improving in accuracy & efficiency, So, It offers better decisions, If you need to make a weather forecast model, your algorithms learn to make more accurate predictions faster, Machine Learning algorithms can handle data that are multi-dimensional and multi-variety, and they can do this in dynamic or uncertain environments.
Machine learning improves efficiency & accuracy over time thanks to the ever-increasing amounts of data that are processed, This gives the algorithm or programs more experience, which can be used to make better decisions or predictions, and it is highly effective at data mining, Weather prediction models are a great example of this improvement, Predictions are made by looking at past weather patterns & events.
Artificial intelligence can used to implement the appropriate measures for neutralizing or protecting against any threat, Machine learning eliminates the gap between the time when a new threat is identified and the time when a response is issued, This near-immediate response is critical in a niche where bots, viruses, worms, hackers and other cyber threats can impact thousands or even millions of people in minutes.
Disadvantages of Machine Learning
It requires massive data sets to train on, these should be inclusive/unbiased, and of good quality, Machine Learning needs enough time to let the algorithms learn and develop enough to fulfill their purpose with a considerable amount of accuracy and relevancy, It needs massive resources to function, This can mean additional requirements of computer power for you.
It may take time (and resources) for Machine Learning to bring results, It is autonomous but highly susceptible to errors, it takes quite some time to recognize the source of the issue, and longer to correct it, such blunders can set off a chain of errors that can go undetected for long periods of time.
It is impossible to make immediate accurate predictions with a machine learning system, machine learning has a lack of variability, machine learning deals with statistical truths rather than literal truths, Machine learning systems can’t offer rational reasons for a particular prediction or decision, They are limited to answering questions rather than posing them, these systems do not understand the context, Depending on the provided data used for training.
You should carefully choose the algorithms for your purpose, The interpretation of results is a major challenge to determine the effectiveness of machine learning algorithms, Based on different algorithms data need to be processed before providing as input to respective algorithms, and it has a significant impact on results to be achieved or obtained.
Machine learning takes time, especially if you have limited computing power, Handling tremendous volumes of data and running computer models sucks up a lot of computing power, which can be quite costly, So, before turning to machine learning, it’s important to consider whether you can invest the amount of time and/or money required to develop the technology to a point where it will be useful.
The precise amount of time involved will vary depending on the data source, the nature of data and how it’s being utilized, So, it’s wise to consult with an expert in data mining and machine learning concerning your project, You should consider whether you’ll need to wait for new data to be generated.
