Exact symbolic artificial intelligence for faster, better assessment of AI fairness Massachusetts Institute of Technology

The neural net owed its runaway victory to GPU power and a “deep” structure of multiple layers containing 650,000 neurons in all. In the next year’s ImageNet competition, almost everyone used neural networks. By 2017, many of the contenders’ error rates had fallen to 5 percent, and the organizers ended the contest. A look back at the decades since that meeting shows how often AI researchers’ hopes have been crushed—and how little those setbacks have deterred them. Today, even as AI is revolutionizing industries and threatening to upend the global labor market, many experts are wondering if today’s AI is reaching its limits. As Charles Choi delineates in “Seven Revealing Ways AIs Fail,” the weaknesses of today’s deep-learning systems are becoming more and more apparent.

For the first method, called supervised learning, the team showed the deep nets numerous examples of board positions and the corresponding “good” questions (collected from human players). The deep nets eventually learned to ask good questions on their own, but were rarely creative. The researchers also used another form of training called reinforcement learning, in which the neural network is rewarded each time it asks a question that actually helps find the ships. Again, the deep nets eventually learned to ask the right questions, which were both informative and creative. Moreover, this study showed that the “synthetic” formulas for models for first and second order kinetics found with water age inputs had similar performance in comparison with the models that included the travel time in the shortest path(s). In this sense, any of both inputs may be used as a variable to explain chlorine decay in the case of small networks, such as Network A or Apulian WDN, without a significant loss of accuracy, since there is a single dominant shortest path for each node.

Apple’s New Benchmark, ‘GSM-Symbolic,’ Highlights AI Reasoning Flaws

For example, multiple studies by researchers Felix Warneken and Michael Tomasello show that children develop abstract ideas about the physical world and other people and apply them in novel situations. For example, in the following video, through observation alone, the child realizes that the person holding the objects has a goal in mind and needs help with opening ChatGPT App the door to the closet. Among the solutions being explored to overcome the barriers of AI is the idea of neuro-symbolic systems that bring together the best of different branches of computer science. At Stability AI, meanwhile, Mason managed the development of major foundational models across various fields and helped the AI company raise more than $170 million.

If you ask DALL-E to create a Roman sculpture of a bearded, bespectacled philosopher wearing a tropical shirt, it excels. If you ask it to draw a beagle in a pink harness chasing a squirrel, sometimes you get a pink beagle or a squirrel wearing a harness. It does well when it can assign all the properties to a single object, but it struggles when there are multiple objects and multiple properties. The attitude of many researchers is that this is a hurdle for DL — larger for some, smaller for others — on the path to more human-like intelligence. For this, Tenenbaum and his colleagues developed a physics simulator in which people would have to use objects to solve problems in novel ways. The same engine was used to train AI models to develop abstract concepts about using objects.

In turn, this diminishes the trust that AI needs to be effective for users. Let’s not forget that this particular technology already has to work with a substantial trust deficit given the debate around bias in data sets and algorithms, let alone the joke about its capacity to supplant humankind as the ruler of the planet. This mistrust leads to operational risks that can devalue the entire business model. One thing to commend Marcus on is his persistence in the need to bring together all achievements of AI to advance the field. And he has done it almost single-handedly in the past years, against overwhelming odds where most of the prominent voices in artificial intelligence have been dismissing the idea of revisiting symbol manipulation. Despite the heavy dismissal of hybrid artificial intelligence by connectionists, there are plenty of examples that show the strengths of these systems at work.

With enough training data and computation, the AI industry will likely reach what you might call “the illusion of understanding” with AI video synthesis eventually… The controlled environment has enabled the developers of CLEVRER to provide richly annotated examples to evaluate the performance of AI models. It allows AI researchers to focus their model development on complex reasoning tasks while removing other hurdles such as image recognition and language understanding.

Deep Dive

Machine learning systems are also strictly bound to the context of their training examples, which is why they’re called narrow AI. For example, the computer vision algorithms used in self-driving cars are prone to making erratic decisions when they encounter unusual situations, such as an oddly parked fire truck or an overturned car. A lot of the skills we acquire in our childhood (walking, running, tying shoelaces, handling utensils, brushing teeth, etc.) are things we learn by rote. We can learn them subconsciously and without doing any form of symbol manipulation in our minds.

OpenAI’s Chat Generative Pre-trained Transformer (ChatGPT) was launched on November 2022 and became the consumer software application with the quickest growth rate in history (Hu, 2023). Concerningly, some of the latest GenAI techniques are incredibly confident and predictive, confusing humans who rely on the results. This problem is not just an issue with GenAI or neural networks, but, more broadly, with all statistical AI techniques.

• They’re essentially pattern-recognition engines, capable of predicting what text should come next based on massive amounts of training data.
• The future of law is undeniably intertwined with neuro-symbolic AI, blending human insight with machine precision.
• They also discuss how humans gather bits of information, develop them into new symbols and concepts, and then learn to combine them together to form new concepts.
• Another key area of research is focused on making AI models smaller, more efficient, and more scalable.
• Knowledge graph embedding (KGE) is a machine learning task of learning a latent, continuous vector space representation of the nodes and edges in a knowledge graph (KG) that preserves their semantic meaning.

In the emulated duckling example, the AI doesn’t know whether a pyramid and cube are similar, because a pyramid doesn’t exist in the knowledge base. To reason effectively, therefore, symbolic AI needs large knowledge bases that have been painstakingly built using human expertise. To shift from generation to reasoning, several key actions are necessary.

Neuro-symbolic AI brings us closer to machines with common sense

The future of law is undeniably intertwined with neuro-symbolic AI, blending human insight with machine precision. As this technology automates the mundane, lawyers must hone uniquely human skills—persuasive speaking and strategic negotiation—that no AI can yet mimic. Interpretability is a requirement for building better AI in the future and fundamental for highly regulated symbolic artificial intelligence industries where inaccuracy risks could be catastrophic such as healthcare and finance. It is also important when understanding what an AI knows and how it came to a decision will be necessary for applying transparency for regulatory audits. “From system 1 deep learning to system 2 deep learning,” in 2019 Conference on Neural Information Processing Systems.

Scene understanding is the task of identifying and reasoning about entities – i.e., objects and events – which are bundled together by spatial, temporal, functional, and semantic relations. MIT researchers have developed a new artificial intelligence programming language that can assess the fairness of algorithms more exactly, and more quickly, than available alternatives. But symbolic AI starts to break when you must deal with the ChatGPT messiness of the world. For instance, consider computer vision, the science of enabling computers to make sense of the content of images and video. Say you have a picture of your cat and want to create a program that can detect images that contain your cat. You create a rule-based program that takes new images as inputs, compares the pixels to the original cat image, and responds by saying whether your cat is in those images.

Reinforcement learning, another subset of machine learning, is the type of narrow AI used in many game-playing bots and problems that must be solved through trial-and-error such as robotics. While narrow AI fails at tasks that require human-level intelligence, it has proven its usefulness and found its way into many applications. A narrow AI system makes your video recommendations in YouTube and Netflix, and curates your Weekly Discovery playlist in Spotify. Alexa and Siri, which have become a staple of many people’s lives, are powered by narrow AI. The project kickstarted the field that has become known as artificial intelligence (AI).

Examples include reading facial expressions, detecting that one object is more distant than another and completing phrases such as “bread and…” The justice system, banks, and private companies use algorithms to make decisions that have profound impacts on people’s lives. Being able to communicate in symbols is one of the main things that make us intelligent. Therefore, symbols have also played a crucial role in the creation of artificial intelligence. If I tell you that I saw a cat up in a tree, your mind will quickly conjure an image. It should also be noted that the expressions that include the travel time in the shortest path(s) for second order kinetics, i.e., Eqs.

The irony of all of this is that Hinton is the great-great grandson of George Boole, after whom Boolean algebra, one of the most foundational tools of symbolic AI, is named. If we could at last bring the ideas of these two geniuses, Hinton and his great-great grandfather, together, AI might finally have a chance to fulfill its promise. The framework starts with a “forward pass” in which the agentic pipeline is executed for an input command. The main difference is that the learning framework stores the input, prompts, tool usage, and output to the trajectory, which are used in the next stages to calculate the gradients and perform back-propagation. AI agents extend the functionality of LLMs by enhancing them with external tools and integrating them into systems that perform multi-step workflows. This doesn’t mean they aren’t impressive (they are) or that they can’t be useful (they are).

Deep learning, the main innovation that has renewed interest in artificial intelligence in the past years, has helped solve many critical problems in computer vision, natural language processing, and speech recognition. However, as the deep learning matures and moves from hype peak to its trough of disillusionment, it is becoming clear that it is missing some fundamental components. • Symbols still far outstrip current neural networks in many fundamental aspects of computation. They are more robust and flexible in their capacity to represent and query large-scale databases. Symbols are also more conducive to formal verification techniques, which are critical for some aspects of safety and ubiquitous in the design of modern microprocessors. To abandon these virtues rather than leveraging them into some sort of hybrid architecture would make little sense.

Another key area of research is focused on making AI models smaller, more efficient, and more scalable. LLMs are incredibly resource-intensive, but the future of AI may lie in building models that are more powerful while being less costly and easier to deploy. Rather than making models bigger, the next wave of AI innovation may focus on making them smarter and more efficient, unlocking a broader range of applications and industries. That bit about not training on customer data will surely appeal to businesses wary of exposing secrets to a third-party AI.

Much of Tim’s work has been focused on ways to make RL agents learn with relatively little data, using strategies known as sample efficient learning, in the hopes of improving their ability to solve more general problems. For us humans, detecting and reasoning about objects in a scene almost go hand in hand. But for current artificial intelligence technology, they’re two fundamentally different disciplines. A new study presented at ICLR 2020 by researchers at IBM, MIT, Harvard, and DeepMind highlight the shortcomings of current AI systems in dealing with causality in videos.

Hinton, LeCun, and Bengio eventually won the 2019 Turing Award and are sometimes called the godfathers of deep learning. And by the early 1980s renewed enthusiasm brought a heyday for researchers in symbolic AI, who received acclaim and funding for “expert systems” that encoded the knowledge of a particular discipline, such as law or medicine. Investors hoped these systems would quickly find commercial applications. The most famous symbolic AI venture began in 1984, when the researcher Douglas Lenat began work on a project he named Cyc that aimed to encode common sense in a machine. To this very day, Lenat and his team continue to add terms (facts and concepts) to Cyc’s ontology and explain the relationships between them via rules. Another benefit of combining the techniques lies in making the AI model easier to understand.

The company intends to produce a toolkit that will allow for the construction of models and those models will be “interpretable,” meaning that users will be able to understand how the AI network came to a determination. That should open up high transparency within models meaning that they will be much more easily monitored and debugged by developers. Artificial intelligence startup Symbolica AI launched today with an original approach to building generative AI models. “Processing time evidence for a default-interventionist model of probability judgments,” in Proceedings of the Annual Meeting of the Cognitive Science Society (Amsterdam), 1792–1797.

The Neuro-Symbolic Dynamic Reasoning AI model

The topic has garnered much interest over the last several years, including at Bosch where researchers across the globe are focusing on these methods. In this short article, we will attempt to describe and discuss the value of neuro-symbolic AI with particular emphasis on its application for scene understanding. In particular, we will highlight two applications of the technology for autonomous driving and traffic monitoring. It was grounded in explicit rules and logical reasoning enabling clarity and transparency of the decision-making process. You can foun additiona information about ai customer service and artificial intelligence and NLP. Symbolic AI’s ability to represent knowledge allowed for the intricate modeling of domains and ensured reliability and consistency when queried. It was particularly adept at tasks requiring rigorous, structured problem-solving.

Its perception module detects and recognizes a ball bouncing on the road. What is the probability that a child is nearby, perhaps chasing after the ball? This prediction task requires knowledge of the scene that is out of scope for traditional computer vision techniques. More specifically, it requires an understanding of the semantic relations between the various aspects of a scene – e.g., that the ball is a preferred toy of children, and that children often live and play in residential neighborhoods. Knowledge completion enables this type of prediction with high confidence, given that such relational knowledge is often encoded in KGs and may subsequently be translated into embeddings. At Bosch Research in Pittsburgh, we are particularly interested in the application of neuro-symbolic AI for scene understanding.

Transformer deep learning architectures have overtaken every other type — especially for large language models, as seen with OpenAI’s ChatGPT, Anthropic PBC’s Claude, Google LLC’s Gemini and many others. That’s thanks to their popularity and the broad presence of tools for their development and deployment, but they’re extremely complex and expensive. They also take colossal amounts of data and energy, are difficult to validate and have a tendency to “hallucinate,” which is when a model confidently relates an inaccurate statement as if it’s true. The research community is still in the early phase of combining neural networks and symbolic AI techniques. Much of the current work considers these two approaches as separate processes with well-defined boundaries, such as using one to label data for the other. The next wave of innovation will involve combining both techniques more granularly.

Take, for example, a neural network tasked with telling apart images of cats from those of dogs. The image — or, more precisely, the values of each pixel in the image — are fed to the first layer of nodes, and the final layer of nodes produces as an output the label “cat” or “dog.” The network has to be trained using pre-labeled images of cats and dogs. During training, the network adjusts the strengths of the connections between its nodes such that it makes fewer and fewer mistakes while classifying the images. If you ask it questions for which the knowledge is either missing or erroneous, it fails.

The next step lies in studying the networks to see how this can improve the construction of symbolic representations required for higher order language tasks. Neurosymbolic AI is also demonstrating the ability to ask questions, an important aspect of human learning. Crucially, these hybrids need far less training data then standard deep nets and use logic that’s easier to understand, making it possible for humans to track how the AI makes its decisions.

Now, researchers are looking at how to integrate these two approaches at a more granular level for discovering proteins, discerning business processes and reasoning. Neuro-symbolic AI merges the analytical capabilities of neural networks, such as ChatGPT and Google’s Gemini, with the structured decision-making of symbolic AI, like IBM’s Deep Blue chess-playing system from the 1990s. This creates systems that can learn from real-world data and apply logical reasoning simultaneously. This union empowers AI to make decisions that closely mimic human thought processes, enhancing its applicability across various fields. The dominant technique in contemporary AI is deep learning (DL) neural networks, massive self-learning algorithms which excel at discerning and utilizing patterns in data. Since their inception, critics have prematurely argued that neural networks had run into an insurmountable wall — and every time, it proved a temporary hurdle.

Bengio has also shunned the idea of hybrid artificial intelligence on several occasions. This is a reality that many of the pioneers of deep learning and its main component, artificial neural networks, have acknowledged in various AI conferences in the past year. Geoffrey Hinton, Yann LeCun, and Yoshua Bengio, the three “godfathers of deep learning,” have all spoken about the limits of neural networks. Artur Garcez and Luis Lamb wrote a manifesto for hybrid models in 2009, called Neural-Symbolic Cognitive Reasoning. And some of the best-known recent successes in board-game playing (Go, Chess, and so forth, led primarily by work at Alphabet’s DeepMind) are hybrids.

With its capacity to model complex geometric forms, it could play a pivotal role in unraveling intricate theories and uncovering novel insights in the realm of theoretical physics. DeepMind’s AlphaGeometry combines neural large language models (LLMs) with symbolic AI to navigate the intricate world of geometry. This neuro-symbolic approach recognizes that solving geometry problems requires both rule application and intuition. LLMs empower the system with intuitive abilities to predict new geometric constructs, while symbolic AI applies formal logic for rigorous proof generation. Unlike current neural network-based AI, which relies heavily on keyword matching, neuro-symbolic AI can delve deeper, grasping the underlying legal principles within case law.

Deep learning algorithms need vast amounts of data to perform tasks that a human can learn with very few examples. Convolutional neural networks (CNNs), used in computer vision, need to be trained on thousands of images of each type of object they must recognize. And even then, they often fail when they encounter the same objects under new lighting conditions or from a different angle.

To overcome these limitations, Google researchers are developing a natural language reasoning system based on Gemini and their latest research. This new system aims to advance problem-solving capabilities without requiring formal language translation and is designed to integrate smoothly with other AI systems. When you build an algorithm using ML alone, changes to input data can cause AI model drift. An example of AI drift is chatbots or robots performing differently than a human had planned. When such events happen, you must test and train your data all over again — a costly, time-consuming effort. In contrast, using symbolic AI lets you easily identify issues and adapt rules, saving time and resources.

“As impressive as things like transformers are on our path to natural language understanding, they are not sufficient,” Cox said. The ability to cull unstructured language data and turn it into actionable insights benefits nearly every industry, and technologies such as symbolic AI are making it happen. Most important, if a mistake occurs, it’s easier to see what went wrong. “You can check which module didn’t work properly and needs to be corrected,” says team member Pushmeet Kohli of Google DeepMind in London.
