How machine learning works
Aspiring machine learning engineers should have clarity about the emerging field of computer engineering and its applications for understanding the subject better. It should help make well-informed decisions about taking up machine learning as a career. The knowledge should help you know how to become a machine learning engineer and whether you are ready for it.
While AI helps computers become smart, Machine Learning works in the background and teaches machines how to become smart. AI cannot flourish without help from Machine Learning, and it will not be wrong to say that Machine Learning holds the center stage in all kinds of technological advancements.
Machine learning stimulates artificial intelligence, considered the brain of computers, enabling machines to think independently without any external assistance. Computers can then act by themselves without the need for programming. Instead of humans programming computers to accomplish specific tasks, as with traditional computers, machine learning allows humans to provide data and describe what they want the program to do.
Computers use that data to train themselves first and then work out ways to carry out the tasks with the help of algorithms. During operation, a computer gathers more data over time which helps it get smarter. However, data labeling is a key factor in enabling computers to correctly use the data. For example, if you want a program to sift through photos of pepperoni pizza and ice cream, you must first label some photos to help the algorithms understand what ice cream and pepperoni pizza look like.
Deep learning and its working modality
Understanding data labeling is also important in distinguishing between machine learning and deep learning. Deep learning is a subset of machine learning but follows a different learning method. Instead of relying on data labeling, deep learning relies on neural networks that draw inspiration from the human brain both in name and structure.
To allow computers to distinguish between pepperoni pizza and ice cream by sorting the photos with the help of deep learning, you must provide a significantly larger set of photos. The computer then deploys the neural networking to sift the photos through several layers of processing to distinguish the pepperoni pizza from the ice cream, one step at a time. The primary layers look at the basic properties like edges or lines between dark and light parts of the images, while the subsequent layers help to identify more complex features like faces and shapes.
Helping computers see and even understand natural language
The gamut of Machine Learning is useful for performing a wide range of tasks and applications besides solving problems. Computers attain the power to see, a phenomenon known as computer vision that helps machines make sense of videos and images. Moreover, Natural Language Processing (NLP) is a fast-growing subset of machine learning that aid computers in making out the meaning of unstructured text. Thus, the role of the machine learning engineer Google is evident when Google processes voice searches and deciphers lengthy text searches. Over and above, voice and speech recognition powers smart assistants like Google Assistant, Amazon’s Alexa, and Apple’s Siri. The smart assistants that helped households get a taste of smart living introduced AI to many consumers for the first time.
Across industries, machine learning applications are gaining momentum through applications in products and within organizations to streamline business processes. For example, machine learning can streamline and augment supply chain operations and is extensively used in business analytics, marketing and sales, and cyber security.
Machine learning helps in bolstering cybersecurity.
Machine learning contributes significantly to deploying cyber security technology more effectively, as a Facebook machine learning engineer admitted. Cyber threats areincreasing fast andgetting more complex and sophisticated while posing tremendous challenges for IT teams to protect their networks and systems. As organizations increasingly move their applications and systems to the cloud, the range of security threats is increasing daily. To create a strong defensive ring against advanced cyber threats, machine learning can help analyze patterns and learn from them to prevent similar attacks while responding to changing behavior.
Armed with Machine Learning, the sentinels of cyber security become more proactive and can pre-empt threats besides preventing cyber-attacks successfully. They are always ready to respond to active attacks as and when they occur. Machine learning can significantly reduce the time spent on routine tasks, allowing organizations to use their resources for more productive purposes.
Data is crucial for the successful deployment of machine learning in cybersecurity.
Machine Learning processes are entirely data-driven for developing and using those patterns with algorithms. Gathering extensive and rich data from every area relevant to the business domain is essential for developing patterns. The data should help to figure out the maximum number of potential outcomes from an identical number of scenarios as possible. The quality of data is as much important as the quantity. Data must be relevant, complete, and rich in context, collected from every potential source, whether within the network, at the endpoint, or in the cloud. To define outcomes, you must depend on clean data that makes sense by focusing on data cleaning.
It begins with the right approach to data.
The right approach to data is critical in deploying cyber security systems powered by machine learning. To ensure that organizations leverage machine learning in their cyber security strategies, business leaders and the top management teams focus on collecting data and its organizing and structuring. Data quality is critical because it must contain information that helps understand everything that happened, not just the security threats.
The data has to be rich to contain every detail about applications, machines, network sensors, and protocols. Data should help to co-relate what happened in the interim between whatever is visible on the network and what you can see at the endpoint. This is the view of a machine learning engineer at Google who oversees cyber security. He explains that stitching the data together is part of the work so that the full picture gives a single representation. Then only you can build different models, create models to capture different aspects of behavior, and then with the help of algorithms, make decisions about when to trigger alerts, when to act in response to potential threats and when to build protections to pre-empt threats.
