Want to know how Deep Learning works? Heres a quick guide for everyone

Machine Learning Fundamentals Basic theory underlying the field of by Javaid Nabi

how machine learning works

When training a machine learning model, machine learning engineers need to target and collect a large and representative sample of data. Data from the training set can be as varied as a corpus of text, a collection of images, sensor data, and data collected from individual users of a service. Overfitting is something to watch out for when training a machine learning model.

Ultimately, this enables security teams to reduce their risk exposure and prepare for an increasingly hostile cyber landscape. Teams that fail to deploy AI for cybersecurity will be more vulnerable to attacks compared to other market players who do. At the same time, there are a number of insider threats that can seem innocuous in nature, but costly nonetheless, such as sending company information over a personal account, or even accidentally misconfiguring access credentials. Fraudulent activities can be difficult to detect, costing agencies valuable time and resources. Ultimately, AI makes it easy for government agencies to detect fraudulent activities as they happen, saving them time and resources while also safeguarding taxpayer dollars.

For example, Bayes’ theorem (1812) defined the probability of an event occurring based on knowledge of the previous conditions that could be related to this event. Years later, in the 1940s, another group of scientists laid the foundation for computer programming, capable of translating a series of instructions into actions that a computer could execute. These precedents made it possible for the mathematician Alan Turing, in 1950, to ask himself the question of whether it is possible for machines to think.

Modeling time series data is an intensive effort, requiring pre-processing, data cleaning, stationarity tests, stationarization methods like detrending or differencing, finding optimal parameters, and more. In short, structured data is searchable and organized in a table, making it easy to find patterns and relationships. It’s also possible to analyze and gain value from unstructured data, such as by using text extraction on PDFs, followed by text classification, but it’s a much more difficult task. In the What is Machine Learning section of the guide, we considered the example of a bank trying to determine whether a loan applicant is likely to default or not.

Disadvantages of using Machine Learning

In the summer of 1955, while planning a now famous workshop at Dartmouth College, John McCarthy coined the term “artificial intelligence” to describe a new field of computer science. Rather than writing programs that tell a computer how to carry out a specific task, McCarthy pledged that he and his colleagues would instead pursue algorithms that could teach themselves how to do so. The goal was to create computers that could observe the world and then make decisions based on those observations—to demonstrate, that is, an innate intelligence.

To achieve this, deep learning uses multi-layered structures of algorithms called neural networks. To analyze the data and extract insights, there exist many machine learning algorithms, summarized in Sect. Thus, selecting a proper learning algorithm that is suitable for the target application is challenging. The reason is that the outcome of different learning algorithms may vary depending on the data characteristics [106].


For example, an algorithm would be trained with pictures of dogs and other things, all labeled by humans, and the machine would learn ways to identify pictures of dogs on its own. Yet for all the success of deep learning at speech recognition, key limitations remain. As a result, there is likely to be a ceiling to how intelligent speech recognition systems based on deep learning and other probabilistic models can ever be. If we ever build an AI like the one in the movie “Her,” which was capable of genuine human relationships, it will almost certainly take a breakthrough well beyond what a deep neural network can deliver. Deep learning combines advances in computing power and special types of neural networks to learn complicated patterns in large amounts of data. Deep learning techniques are currently state of the art for identifying objects in images and words in sounds.

When a classification model it produces a probability that the input data matches one of the classes from the training data. It thus produces a prediction or correlation rather than a statement of causality. These patterns that machine learning systems can see are often so granular that no human could ever catch them. In the training phase, a data scientist supplies some input data and describes the expected output using historical information.

  • Semisupervised learning works by feeding a small amount of labeled training data to an algorithm.
  • These algorithms use machine learning and natural language processing, with the bots learning from records of past conversations to come up with appropriate responses.
  • User comments are classified through sentiment analysis based on positive or negative scores.
  • If the learning rate is too low, the gradient descent may stall and never completely converge.
  • Machine learning is a powerful tool that can be used to solve a wide range of problems.
