How to teach AI to reason about videos

And it’s very hard to communicate and troubleshoot their inner-workings. Symbolic artificial intelligence is very convenient for settings where the rules are very clear cut,  and you can easily obtain input and transform it into symbols. In fact, rule-based systems still account for most computer programs today, including those used to create deep learning applications.

Despite ongoing efforts, finding the perfect AI symbol is still in its early stages. However, the quest continues, marking symbolic progress in the ever-evolving field of artificial intelligence. The performance of NS-DR is considerably higher than pure deep learning models on explanatory, predictive, and counterfactual challenges. The counterfactual benchmark still stands at a modest 42 percent accuracy, however, which speaks to the challenges of developing AI that can understand the world as we do.

The neuro-symbolic system must detect the position and orientation of the objects in the scene to create an approximate 3D representation of the world. “These systems develop quite early in the brain architecture that is to some extent shared with other species,” Tenenbaum says. These cognitive systems are the bridge between all the other parts of intelligence such as the targets of perception, the substrate of action-planning, reasoning, and even language. These capabilities are often referred to as “intuitive physics” and “intuitive psychology” or “theory of mind,” and they are at the heart of common sense. We break down the world into objects and agents, and interactions between these objects and agents.

This time, their approach outperformed all compared baselines on both tasks with an even larger performance gap compared to that on conventional LLM benchmarks. The task description, input, and trajectory are data-dependent, which means they will be automatically adjusted as the pipeline gathers more data. The few-shot demonstrations, principles, and output format control are fixed for all tasks and training examples. The language loss consists of both natural language comments and a numerical score, also generated via prompting. Instead of modeling the mind, an alternative recipe for AI involves modeling structures we see in the brain. After all, human brains are the only entities that we know of at present that can create human intelligence.

As neuro-symbolic AI advances, it promises sophisticated applications and highlights crucial ethical considerations. Integrating neural networks with symbolic AI systems should bring a heightened focus on ChatGPT App data privacy, fairness and bias prevention. This emphasis arises because neuro-symbolic AI combines vast data with rule-based reasoning, potentially amplifying biases present in the data or the rules.

This approach was called symbolic AI, because our thoughts and reasoning seem to involve languages composed of symbols (letters, words, and punctuation). Symbolic AI involved trying to find recipes that captured these symbolic expressions, as well as recipes to manipulate these symbols to reproduce reasoning and decision making. For instance, in the shape example I started this article with, a neuro-symbolic system would use a neural network’s pattern recognition capabilities to identify objects. The fact that it sounds as if it is is proof positive of just how simple it actually is. It’s the kind of question that a preschooler could most likely answer with ease.

Fact or Fiction: Combatting Deepfakes During an Election Year

When deep learning reemerged in 2012, it was with a kind of take-no-prisoners attitude that has characterized most of the last decade. By 2015, his hostility toward all things symbols had fully crystallized. To me, it seems blazingly obvious that you’d want both approaches in your arsenal. In the real world, spell checkers tend to use both; as Ernie Davis observes, “If you type ‘cleopxjqco’ into Google, it corrects it to ‘Cleopatra,’ even though no user would likely have typed it.

It follows that neuro-symbolic AI combines neural/sub-symbolic methods with knowledge/symbolic methods to improve scalability, efficiency, and explainability. The demand for systems that not only deliver answers but also explain their reasoning transparently and reliably ChatGPT is becoming critical, especially in contexts where AI is used for crucial decision-making. Organizations bear a responsibility to explore and utilize AI responsibly, and the emphasis on trust is growing as AI leaders seek new ways of leveraging LLMs safely.

Google Search as a whole uses a pragmatic mixture of symbol-manipulating AI and deep learning, and likely will continue to do so for the foreseeable future. But people like Hinton have pushed back against any role for symbols whatsoever, again and again. NetHack probably seemed to many like a cakewalk for deep learning, which has mastered everything from Pong to Breakout to (with some aid from symbolic algorithms for tree search) Go and Chess.

The symbolic part of the AI has a small knowledge base about some limited aspects of the world and the actions that would be dangerous given some state of the world. They use this to constrain the actions of the deep net — preventing it, say, from crashing into an object. The Bosch code of ethics for AI emphasizes the development of safe, robust, and explainable AI products. By providing explicit symbolic representation, neuro-symbolic methods enable explainability of often opaque neural sub-symbolic models, which is well aligned with these esteemed values. In the context of autonomous driving, knowledge completion with KGEs can be used to predict entities in driving scenes that may have been missed by purely data-driven techniques. For example, consider the scenario of an autonomous vehicle driving through a residential neighborhood on a Saturday afternoon.

• After all, human brains are the only entities that we know of at present that can create human intelligence.
• The type and material of objects are few, all the problems are set on a flat surface, and the vocabulary used in the questions is limited.
• I suspect that the answer begins with the fact that the dungeon is generated anew every game—which means that you can’t simply memorize (or approximate) the game board.
• But in December, a pure symbol-manipulation based system crushed the best deep learning entries, by a score of 3 to 1—a stunning upset.

This friend was Marvin Minsky, he knew Rosenblatt since adolescence and his book was the perfect excuse for the supporters of symbolic AI to spread the idea that neural networks didn’t work¹. “We believe this transition from model-centric to data-centric agent research is a meaningful step towards approaching artificial general intelligence,” the researchers write. This top-down scheme enables the agent symbolic learning framework to optimize the agent system “holistically” and avoid getting stuck in local optima for separate components. Maybe you don’t think that sounds like a lot — after all, you can store that on a regular desktop computer.

This is essentially a neuro-symbolic approach, where the neural network, Gemini, translates natural language instructions into the symbolic formal language Lean to prove or disprove the statement. Similar to AlphaZero’s self-play mechanism, where the system learns by playing games against itself, AlphaProof trains itself by attempting to prove mathematical statements. Each proof attempt refines AlphaProof’s language model, with successful proofs reinforcing the model’s capability to tackle more challenging problems. Neuro-symbolic AI is a synergistic integration of knowledge representation (KR) and machine learning (ML) leading to improvements in scalability, efficiency, and explainability.

Thus, the numerous failures in large language models show they aren’t genuinely reasoning but are simply going through a pale imitation. For Marcus, there is no path from the stuff of DL to the genuine article; as the old AI adage goes, you can’t reach the Moon by climbing a big enough tree. Thus he takes the current DL language models as no closer to genuine language than Nim Chimpsky with his few signs of sign language. The DALL-E problems aren’t quirks of a lack of training; they are evidence the system doesn’t grasp the underlying logical structure of the sentences and thus cannot properly grasp how the different parts connect into a whole. Today’s seemingly insurmountable wall is symbolic reasoning, the capacity to manipulate symbols in the ways familiar from algebra or logic. As we learned as children, solving math problems involves a step-by-step manipulation of symbols according to strict rules (e.g., multiply the furthest right column, carry the extra value to the column to the left, etc.).

Neural networks are almost as old as symbolic AI, but they were largely dismissed because they were inefficient and required compute resources that weren’t available at the time. In the past decade, thanks to the large availability of data and processing power, deep learning has gained popularity and has pushed past symbolic AI systems. Since EPR can select independent variables (model input) which are treated as hypothesis, the user can build other inputs, by aggregating the original ones, to introduce prior physical knowledge as in this case. As well as the inputs, the selected function, exponents, and the maximum number of terms of the EPR model are hypothesis, i.e. candidates to modelling result. The EPR strategy, then, generates understandable and less complex models in term of parameters in contrast with artificial neural networks.

The practice showed a lot of promise in the early decades of AI research. But in recent years, as neural networks, also known as connectionist AI, gained traction, symbolic AI has fallen by the wayside. As explained above, running EPR-MOGA returns a set of Pareto models (i.e., all non-dominant to each other) having different complexity and accuracy on the training inputs.

Researchers believe that those same rules about the organization of the world could be discovered and then codified, in the form of an algorithm, for a computer to carry out. Os Keyes, a PhD candidate at the University of Washington focusing on law and data ethics, notes that symbolic AI models depend on highly structured data, which makes them both “extremely brittle” and dependent on context and specificity. Symbolic AI needs well-defined knowledge to function, in other words — and defining that knowledge can be highly labor-intensive.

Gaps of up to 15 percent accuracy between the best and worst runs were common within a single model and, for some reason, changing the numbers tended to result in worse accuracy than changing the names. “What’s important is to develop higher-level strategies that might transfer in new situations. Once the neuro-symbolic agent has a physics engine to model the world, it should be able to develop concepts that enable it to act in novel ways. We might not be able to predict the exact trajectory of each object, but we develop a high-level idea of the outcome. When combined with a symbolic inference system, the simulator can be configurated to test various possible simulations at a very fast rate. Many engineers and scientists think that they should not worry about politics or social events around them because they have nothing to do with science.

AlphaProof is an AI system designed to prove mathematical statements using the formal language Lean. It integrates Gemini, a pre-trained language model, with AlphaZero, a reinforcement learning algorithm renowned for mastering chess, shogi, and Go. In 2019, Kohli and colleagues at MIT, Harvard and IBM designed a more sophisticated challenge in which the AI has to answer questions based not on images but on videos. The videos feature the types of objects that appeared in the CLEVR dataset, but these objects are moving and even colliding. The AI hype back then was all about the symbolic representation of knowledge and rules-based systems—what some nostalgically call “good old-fashioned AI” (GOFAI) or symbolic AI.

The attributes of the WDNs used for this research are summarized in Table 1, where the case studies are ordered from smallest to largest and most complex. The hydraulic models of the networks and the corresponding demand patterns are shown in Fig. Drawing inspiration from Daniel Kahneman’s Nobel Prize-recognized concept of “thinking, fast and slow,” DeepMind researchers Trieu Trinh and Thang Luong highlight the existence of dual-cognitive systems. “Akin to the idea of thinking, fast and slow, one system provides fast, ‘intuitive’ ideas, and the other, more deliberate, rational decision-making,” said Trinh and Luong.

• This approach was called symbolic AI, because our thoughts and reasoning seem to involve languages composed of symbols (letters, words, and punctuation).
• One of Hinton’s postdocs, Yann LeCun, went on to AT&T Bell Laboratories in 1988, where he and a postdoc named Yoshua Bengio used neural nets for optical character recognition; U.S. banks soon adopted the technique for processing checks.
• New applications such as summarizing legal contracts and emulating human voices are providing new opportunities in the market.

One example is the Neuro-Symbolic Concept Learner, a hybrid AI system developed by researchers at MIT and IBM. The NSCL combines neural networks to solve visual question answering (VQA) problems, a symbolic artificial intelligence class of tasks that is especially difficult to tackle with pure neural network–based approaches. The researchers showed that NCSL was able to solve the VQA dataset CLEVR with impressive accuracy.

It also had to be addressed explicitly using the symbols used in its models. By blending the structured logic of symbolic AI with the innovative capabilities of generative AI, businesses can achieve a more balanced, efficient approach to automation. This article explores the unique benefits and potential drawbacks of this integration, drawing parallels to human cognitive processes and highlighting the role of open-source models in advancing this field. Their Sum-Product Probabilistic Language (SPPL) is a probabilistic programming system. Probabilistic programming languages make it much easier for programmers to define probabilistic models and carry out probabilistic inference — that is, work backward to infer probable explanations for observed data.

At Unlikely, his role will be to shepherd its now 60 full-time staff — who are based largely between Cambridge (U.K.) and London. 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. Decades of computer science and cognitive science have proven that being able to store and manipulate abstract concepts is an essential part of any intelligent system. And that is why symbol-manipulation should be a vital component of any robust AI system.

This perspective is now supported by numerous analysts, including Gartner. In their 2024 Impact Radar, they stated that knowledge graphs—a symbolic AI technology of the past—are the critical enabler for generative AI. Adopting a hybrid AI approach allows businesses to harness the quick decision-making of generative AI along with the systematic accuracy of symbolic AI.

At Bosch, he focuses on neuro-symbolic reasoning for decision support systems. Alessandro’s primary interest is to investigate how semantic resources can be integrated with data-driven algorithms, and help humans and machines make sense of the physical and digital worlds. You can foun additiona information about ai customer service and artificial intelligence and NLP. Alessandro holds a PhD in Cognitive Science from the University of Trento (Italy). In fact, rule-based AI systems are still very important in today’s applications. Many leading scientists believe that symbolic reasoning will continue to remain a very important component of artificial intelligence.

By providing answers with not just source references but also logical chains of reasoning, RAR can foster a level of trust and transparency that’s becoming crucial in today’s increasingly regulated world. RAR offers comprehensive accuracy and guardrails against the hallucinations that LLMs are so prone to, grounded by the knowledge graph. It lacked learning capability and had difficulty navigating the nuances of complex, real-world environments.
