What Is Machine Learning And Why Is It Important


In artificial intelligence, machine learning refers to the development of systems that can learn from past data, recognise patterns, and make logical judgments with little human input. Analytical models may be built utilising a variety of digital information, including numbers, words, clicks, and photos, using this type of data analysis.

Input data is fed into machine learning systems, which then use automated optimization techniques to increase the accuracy of their outputs. There are two main factors that determine the quality of a machine-learning model:

The accuracy and completeness of the data provided as input. “Trash in, garbage out” is a frequent saying in the field of machine learning. In other words, if you input poor quality or chaotic data, the model’s result is likely to be erroneous.

Secondly, the model itself. A data scientist may pick from a wide variety of algorithms in machine learning, each of which has a distinct purpose. You must choose the right algorithm for each application. There is a lot of buzz regarding neural networks because of their great accuracy and adaptability. While a simpler model may perform better when dealing with a little quantity of data, this isn’t always the case.

Accuracy is improved with each iteration of the machine learning model. That, in turn, suggests that its forecasts and judgments will be more accurate.

Why is Machine Learning Important?

What’s the point of implementing machine learning? With ever-increasing amounts of data, ever-more-affordable computing power, and ever-more-accessible high-speed Internet, machine learning is becoming more important. Models that can interpret enormously complicated data sets may be swiftly and automatically developed using these digital transformation principles.

Cutting expenses and improving quality of life may be achieved via a wide range of applications of machine learning, such as suggesting products/services, identifying security breaches and enabling self-driving automobiles. Machine learning is becoming increasingly commonplace and will soon be used in many aspects of human life as a result of increased availability to data and computational capacity.

How Does Machine Learning Work?

There are four key steps you would follow when creating a machine learning model.

1. Choose and Prepare a Training Data Set

To fine-tune model parameters, a machine learning application needs data that may be used as training examples. Data used for training may be “labelled,” which means that categories or anticipated values have been assigned to the data so that the machine learning mode can better predict them. Unlabeled training data means that the model will have to extract features and assign clusters on its own.

Data should be separated into training and testing subsets before being labelled. To train the model, we utilise the former; to assess and enhance the model, we use the latter.

2. Select an Algorithm to Apply to the Training Data Set

Many factors will influence the sort of machine learning algorithm you select:

  • Clustering and dimensionality reduction may both benefit from labelled training data and unlabeled data, regardless of the application.
  • What is the size of the data used for training?
  • In what ways does the model attempt to address the issue?

Regression methods such as basic least square regression or logistic regression are often used for prediction or classification use cases. K-means and closest neighbour algorithms may be used to analyse unlabeled data. Some algorithms, such as neural networks, may be used for both clustering and prediction at the same time.

3. Train the Algorithm to Build the Model

An algorithm is trained by fine-tuning model variables and parameters in order to better anticipate the desired outcomes. Iterative training of a machine learning algorithm employs several optimization strategies based on the model used. As a result of machine learning, these optimization approaches don’t need any human involvement. With little to no input from the user, the machine learns from the data it receives.

4. Use and Improve the Model

In the last stage, fresh data is fed into the model in order to keep it up to date and accurate throughout time. As a result, how the new information will be sourced depends on the situation at hand. Machine learning models for autonomous vehicles may use real-world data, such as road conditions, objects, and traffic rules, to train themselves.

Use Cases for Machine Learning in the SOC

Machine Learning Methods

What Is Supervised Machine Learning

As training data, supervised machine learning algorithms employ labelled data where the proper outputs are already known to the input data. To train a machine learning algorithm, it takes in a set of inputs and the matching accurate outputs. Model accuracy is calculated by comparing anticipated results with actual results, and then model parameters are optimised to enhance accuracy.

Unlabeled data may be accurately predicted using supervised machine learning, which looks for patterns. If there are too many data inputs for a person to successfully handle, it is often utilised in automation, over enormous volumes of data records, or in these situations: A fraud detection algorithm, for example, may pick up on suspicious credit card transactions or identify an insurance client who is most likely to submit a claim.

What Is Unsupervised Machine Learning

Applied to data that does not have a structured or objective solution, unsupervised machine learning is ideal. The proper output for a particular input is not predetermined. Instead, the algorithm must analyse the data and make a judgement based on that data. The goal is to look at the data and see whether there is any structure to it.

Transactional data lends itself nicely to unsupervised machine learning. The programme, for example, may discover client groups with similar characteristics. Customers that fall into one of these categories may then be targeted with ads that are tailored to their needs. Unsupervised learning approaches include nearest-neighbor mapping, self-organizing maps, singular value decomposition, and k-means clustering, among other popular methods. After that, the algorithms are put to work for things like subject segmentation, spotting anomalies, and making recommendations.

What Can Machine Learning Do: Machine Learning in the Real World

Despite the fact that machine learning has been available for decades, it has only recently been able to apply and automatically perform difficult mathematical computations involving large datasets. From workplace AIOps to internet retail, machine learning has a wide range of applications today. The following are some instances of machine learning in action today:

  • APTs, zero-day attacks, and insider threats may all be detected using behavioural analytics in cyber security.
  • Self-driving vehicle initiatives include Waymo (a subsidiary of Alphabet Inc.) and Tesla’s Autopilot, which is a step below genuine self-driving automobiles.
  • Siri, Alexa, and Google Assistant are examples of voice-activated digital assistants that search the web in response to human orders.
  • Web and app-based recommendation systems powered by machine learning algorithms, such as Netflix, Amazon, and YouTube.
  • Data aggregation and cyber resilience solutions that identify high-risk customers and patterns of suspicious behaviour from a variety of sources. Using supervised and unsupervised machine learning, these systems are able to categorise transactions for financial companies as legal or fraudulent. To ensure that an unusual transaction made using the customer’s financial credentials is authentic, the credit card firm will send a text message to the customer. Machine learning has come so far in the field of fraud detection that many credit card firms now offer “no-fault” policies to customers in the event that their algorithms miss fraudulent transactions.
  • Facial identification, reading handwriting on deposited checks, traffic monitoring and counting the number of people in a room may all be reliably performed using image recognition.
  • Unwanted email is kept out of inboxes by spam filters.
  • Utilities that use sensor data to improve efficiency and save expenses.
  • Patients’ health may be continually monitored with the use of wearable medical gadgets that collect data in real time.
  • Real-time traffic analysis and route recommendations for taxi applications.
  • Analyzing how people feel about a passage of text is known as sentiment analysis. Sentiment analysis may be used to Twitter, consumer feedback, and survey participants:
  • Detecting the tone of tweets aimed towards a person or corporation is one approach to assess brands on Twitter. Crimson Hexagon and Nuvi, for example, give this in real time.
    You can tell a lot about your business from the tone of consumer evaluations. If there is no ranking system and just free text user feedback, this is extremely valuable.
    An instant assessment of how survey respondents feel may be obtained using sentiment analysis on free text survey replies. This is applied by Qualtrics in their surveys.
  • Machine learning is used to cluster clients based on their purchasing behaviour in order to identify distinct customer kinds or personas. As a result, you’ll have a deeper understanding of your most important and underserved consumers.
  • It is simple to use ctrl+f to find certain words and phrases inside a document, but document searches may be challenging if you do not have access to the precise content you want. Fuzzy approaches and topic modelling may make this process simpler by enabling you to search materials without knowing the specific language you’re searching for, thanks to machine learning.
