What is Neuro Symbolic Artificial Intelligence and Why Does it Make AI Explainable?

symbolic artificial intelligence

Possible concrete symbol manipulation tasks for study can be found all over AI and computer science, such as term rewriting, list, tree and graph manipulations, executing formal grammars, elementary algebra, logical deduction. In-depth studies of these from a deep learning perspective would provide systems with elementary capabilities that can then be composed for more complex solutions, or used as modules in larger AI systems [HarmelenT19]. On the other hand, Neural Networks are a type of machine learning inspired by the structure and function of the human brain. Neural networks use a vast network of interconnected nodes, called artificial neurons, to learn patterns in data and make predictions. Neural networks are good at dealing with complex and unstructured data, such as images and speech. They can learn to perform tasks such as image recognition and natural language processing with high accuracy.

What is symbolic AI in artificial intelligence?

What is Symbolic AI? Symbolic AI is an approach that trains Artificial Intelligence (AI) the same way human brain learns. It learns to understand the world by forming internal symbolic representations of its “world”. Symbols play a vital role in the human thought and reasoning process.

The recent rise in hate, abuse, and fake news in online discourse [3, 4, 5, 6] has made it imperative that effective methods are developed, in particular, those which are interpretable [7]. In order to determine whether a paper falls into the NeSy AI theme, we read the abstract (and sometimes the introduction). As mentioned before, we are aware that not all papers relevant for NeSy AI are phrased in such terms, i.e. we acknowledge that we may have missed a few relevant papers. It still seems a reasonable assumption that the sum of our selected papers represents a valid cross-section. We are also aware that restricting our attention to the above-mentioned five conferences leaves out a lot of relevant work. However our focus was on recent, mainstream AI research, and we believe that our selection is reasonable for this purpose.

Combining Deep Neural Nets and Symbolic Reasoning

The second reason is tied to the field of AI and is based on the observation that neural and symbolic approaches to AI complement each other with respect to their strengths and weaknesses. For example, deep learning systems are trainable from raw data and are robust against outliers or errors in the base data, while symbolic systems are brittle with respect to outliers and data errors, and are far less trainable. It is therefore natural to ask how neural and symbolic approaches can be combined or even unified in order to overcome the weaknesses of either approach. Traditionally, in neuro-symbolic AI research, emphasis is on either incorporating symbolic abilities in a neural approach, or coupling neural and symbolic components such that they seamlessly interact [2]. We investigate an unconventional direction of research that aims at converting neural networks, a class of distributed, connectionist, sub-symbolic models into a symbolic level with the ultimate goal of achieving AI interpretability and safety. To that end, we propose Object-Oriented Deep Learning, a novel computational paradigm of deep learning that adopts interpretable “objects/symbols” as a basic representational atom instead of N-dimensional tensors (as in traditional “feature-oriented” deep learning).

Neuro-Symbolic AI also learns with a much smaller training dataset, making data acquisition a lot easier ¹. Neuro-Symbolic AI is proven to solve much harder problems and is inherently more comprehensive in terms of decisions and actions. It is one form of assumption, and a strong one, while deep neural architectures contain other assumptions, usually about how they should learn, rather than what conclusion they should reach. The ideal, obviously, is to choose assumptions that allow a system to learn flexibly and produce accurate decisions about their inputs. A certain set of structural rules are innate to humans, independent of sensory experience.

The car failed to recognize the person (partly obscured by the stop sign) and the stop sign (out of its usual context on the side of a road); the human driver had to take over. The scene was far enough outside of the training database that the system had no idea what to do. If machine learning can appear as a revolutionary approach at first, its lack of transparency and a large amount of data that is required in order for the system to learn are its two main flaws. Companies now realize how important it is to have a transparent AI, not only for ethical reasons but also for operational ones, and the deterministic (or symbolic) approach is now becoming popular again.

Applying symbolic reasoning to it can take it a step further to tell more exciting properties about the object, such as the area, volume, etc. The recent adaptation of deep neural network-based methods to reinforcement learning and planning domains has yielded remarkable progress on individual tasks. In pursuit of efficient and robust generalization, we introduce the Schema Network, an object-oriented generative physics simulator capable of disentangling multiple causes of events and reasoning backward through causes to achieve goals.

The IndustryWired magazine is your go-to source for industry insights and trends from Industry experts to help you stay ahead of the curve. Formal applications should be accompanied by a research proposal and made via the University of Bath’s online application form. As AI becomes more integrated into enterprises, a substantially unknown aspect of the technology is emerging – it is difficult, if not impossible, for knowledge workers (or anybody else) to understand why it behaves the way it does.

Controversies arose from early on in symbolic AI, both within the field—e.g., between logicists (the pro-logic “neats”) and non-logicists (the anti-logic “scruffies”)—and between those who embraced AI but rejected symbolic approaches—primarily connectionists—and those outside the field. The gist is that humans were never programmed (not like a digital computer, at least) — humans have become intelligent through learning. But although computers are generally much faster and more precise than the human brain at sequential tasks, such as adding numbers or calculating chess moves, such programs are very limited in their scope. Something as trivial as identifying a bicycle among a crowded pedestrian street or picking up a hot cup of coffee from a desk and gently moving it to the mouth can send a computer into convulsions, nevermind conceptualizing or abstraction (such as designing a computer itself). For decades, engineers have been programming machines to perform all sorts of tasks — from software that runs on your personal computer and smartphone to guidance control for space missions. In the case of genes, small moves around a symbolic ai genome are done when mutations occur, and this constitutes a blind exploration of the solution space around the current position, with a descent method but without a gradient.

What is a Logical Neural Network?

This limitation makes it very hard to apply neural networks to tasks that require logic and reasoning, such as science and high-school math. The advantage of neural networks is that they can deal with messy and unstructured data. Instead of manually laboring through the rules of detecting cat pixels, you can train a deep learning algorithm on many pictures of cats. When you provide it with a new image, it will return the probability that it contains a cat. Symbolic AI involves the explicit embedding of human knowledge and behavior rules into computer programs. But in recent years, as neural networks, also known as connectionist AI, gained traction, symbolic AI has fallen by the wayside.

With neuro-symbolic AI, artificial intelligence will become smarter and more intelligent. This requires less training data and tracking the steps required to make inferences and draw conclusions. Neuro-symbolic AI characteristics that can overcome the limitations of artificial intelligence include deep learning. Humans use symbols as an essential part of communication, making them intelligent like humans.
