Pattern recognition is the automatic recognition of regularities in data. In recent years, it has become important for many industries, especially with the development of artificial intelligence and machine learning.
But what exactly is pattern recognition, and how is it relevant in the medical world as well as in the technical world? Pattern recognition is enabled by a mechanism called a deep neural network (DNN). will be These DNNs are purpose-built to “simulate the behavior of the human brain” by combining data inputs, weights and biases, as IBM describes it. This may sound a lot like machine learning, but machine learning relies on leveraging structured data, whereas deep learning (where deep neural networks are applied) uses unstructured data. Use it to recognize regularities and draw relationships.
This seems irrelevant until you see some real world applications and how such technology is being used to advance certain medical fields.
One of the powerful tools enabled by the deep learning process is the elimination of the “human dependency” factor through automated feature extraction. In this practice, the initial set of data is classified into smaller categories by identifying features.
To give a simple example, to develop a simple algorithm for distinguishing between animal types, a DNN would pay special attention to the ears and determine which set of ears has the characteristics of feline, canine, etc. We need to recognize dolphins instead of relying on humans. Do this simple task. This is reducing reliance on human intervention, the ultimate goal of medical technology.
A few years ago a study showed that pigeons can detect breast cancer just like humans. Birds were taught to distinguish between malignant and benign breast tissue on scans and were rewarded for presenting the correct answer. Considering the determination of a group of four pigeons, the detection accuracy reached 99% of his, a clearly significant result.
The success of pigeons suggests that pigeons are well suited to better understand human medical image recognition. This has shown potential advantages in the development of medical imaging hardware, image processing, and image analysis tools. But perhaps most importantly, pigeons’ basic ability to recognize patterns in data means that it will ultimately reduce the involvement of experts and, in turn, spur growth in the field. is. If this is something pigeons can do, the implications for artificial intelligence are considerable.
For such scans, rather than identifying distinct features such as an animal’s ears, deep neural networks can be used to identify more subtle differences such as malignant and benign tissue.
All the evidence underscores the fact that using pigeons for image analysis is just a step in the right direction to completely eliminate the need to hire medical professionals for these mundane tasks. I’m here.
With the development of pattern recognition algorithms in medical technology, two additional machine learning concepts have become increasingly important.
A decision support system (DSS), as the name suggests, is an information system that supports decision making through judgment and access to data. DSS helps advanced teams navigate large amounts of unstructured data and, especially in the medical world, diagnostic professionals.
The second is Bayesian Networks (BN), which are gaining popularity in diagnostics and other areas of the medical world. These are constructed as probabilistic graphical models to represent the data. The reason for its popularity is that it does not explicitly require large datasets, unlike many pure machine learning methods. They combine expert knowledge and collected data where they are lacking. The importance of this is that by incorporating both of these data formats, these networks can form robust spines of meaningful decision support systems.
So how do these BNs act as real support structures in medical diagnostics?
According to ScienceDirect, half of all models of lung disease aim to calculate the risk of exacerbation of already diagnosed diseases (such as asthma). Other models use clinical indicators and symptoms to assess the probability of a particular disease. This is where BN comes into play. An online application, accessible on a smartphone or laptop, determines the patient’s current condition through questionnaires and his BN model, and provides instructions and relevant information for diagnosis and treatment (this is part of a decision support system). department). ). In addition, the app provides patient health data to medical professionals.
While this may not seem particularly sophisticated or original, it is clear here that deep learning is becoming the new central tool in medical diagnosis. Because Bayesian networks and decision support systems incorporate both human expertise and raw data, clinicians are supported by collaborative tools that are reliable and efficient backend systems.
Pattern recognition in medicine can therefore be considered an umbrella term for all methods and systems that classify large amounts of data and find regularities or salient features with the intention of drawing relationships and conclusions.
Whether human experts or technologically developed sorting algorithms, pattern recognition techniques are being used to drive advancements and subsequent automation in the medical world. If pigeons can detect breast cancer, great possibilities will open up. Just start thinking about the possibilities that exist within the resources available to you and you can imagine the scale and power enabled by modern technology and the potential impact on lasting change.
