Executive summary:
Neurosymbolic AI combines neural networks with symbolic AI to create systems that can both learn from data and apply logical reasoning. Neural networks recognize patterns but can't explain their decisions or follow rules. Symbolic AI provides transparent logic but can't handle messy data or learn from experience. When paired together, you get AI that processes natural language while enforcing business policies, spots visual defects while applying quality standards, or predicts equipment failures while explaining the root causes.
Talbot West's modular architecture lets organizations build these neurosymbolic systems by mixing and matching AI components. Combine a large language model with a knowledge graph for grounded customer service. Each module in a CHAI ensemble can be neural, symbolic, or both, configured precisely for your use case rather than forced into a monolithic solution.
Neurosymbolic AI blends the power of generative AI with the groundedness of knowledge graphs or other ontological frameworks.
Neurosymbolic AI pairs neural networks with symbolic reasoning systems to create AI that can both learn from experience and apply logical rules. Think of it as combining the pattern recognition capabilities of a neural network (which can identify a cat in a photo after seeing thousands of examples) with the logical precision of symbolic AI that knows cats are mammals, mammals are warm-blooded, and therefore cats are warm-blooded.
Neural networks excel at finding patterns in data. They learn from examples, handle ambiguous inputs, and work with unstructured information such as images, audio, and natural language. A neural network can read a contract and understand its general meaning, recognize sentiment in customer feedback, or spot anomalies in sensor readings. But ask it to explain why it made a specific decision or to guarantee it will follow a particular rule, and it can't. Neural networks operate as black boxes, making decisions through layers of weighted connections that resist human interpretation.
Symbolic AI takes the opposite approach. It encodes knowledge as explicit rules, relationships, and logical structures that humans can read and verify. A symbolic system can navigate a company's org chart, apply if-then business rules, or trace through a diagnostic decision tree. Every decision has a clear audit trail. Every conclusion follows from defined premises. But symbolic AI can't make sense of messy, unstructured data. It can't learn from new examples, adapt to unexpected inputs, or handle the ambiguity inherent in human language.
Neurosymbolic AI fuses elasticity and logic. The neural components handle perception, pattern recognition, and learning from data. The symbolic components enforce constraints, apply domain knowledge, and provide explainable reasoning paths. The neural network might understand a customer's frustrated complaint in natural language, while the symbolic system navigates company policies to determine valid resolution options and their approval requirements.
This fusion happens through various architectural patterns. Sometimes a neural network feeds processed information to a symbolic reasoner. Sometimes symbolic rules constrain neural network outputs. Sometimes both components work in parallel, with an orchestration layer choosing which approach fits the current task. The specific configuration depends on the problem you're solving, but the principle remains constant: combine learning with reasoning to get capabilities neither approach provides alone.
Cognitive Hive AI (CHAI) is Talbot West's modular framework for building AI systems that can be configured precisely to match organizational needs. Rather than deploying monolithic AI solutions that force you to accept predefined capabilities, CHAI lets you assemble exactly the AI components your use case requires, including any combination of neural and symbolic modules.
CHAI treats AI capabilities as composable building blocks. Need natural language processing paired with a knowledge graph? Add those modules. Want computer vision working alongside business rule engines? Configure them together. Require predictive analytics constrained by regulatory requirements? Combine neural forecasting with symbolic compliance checking. Each module operates independently but communicates through standardized interfaces, creating an ensemble that's greater than the sum of its parts and building toward total organizational intelligence as outlined in our 2030 thesis.
This modular architecture makes CHAI particularly powerful for neurosymbolic implementations. You can start with a focused pairing, perhaps a large language model grounded by a domain-specific knowledge graph, then expand the system over time. Add a computer vision module to process images. Integrate a constraint solver to optimize decisions within defined parameters. Connect time-series analysis to detect patterns while a causal reasoning module explains why they occur. The system grows with your needs in a composable manner.
The flexibility extends to how neural and symbolic components interact. Some use cases work best with neural networks preprocessing data for symbolic reasoning. Others need symbolic rules constraining neural outputs. Still others benefit from parallel processing where both approaches tackle the same problem and an orchestration layer synthesizes their insights. CHAI supports all these patterns and more, adapting to the specific requirements of your domain rather than forcing a predetermined structure.
Unlike black-box AI products where you can't see or control how decisions are made, neurosymbolic CHAI provides visibility into how information flows between modules. You can trace how the neural network's pattern recognition feeds into the symbolic system's logical reasoning. You can see which modules influenced a decision and why. This transparency is essential for regulated industries, high-stakes decisions, and any application where trust and accountability matter.
One category of neurosymbolic AI system is that of a knowledge graph paired with a deep neural network, for example a large language model. This combination gives the combined capability to "know" facts grounded in the knowledge graph as well as "learn" patterns from data.
BizForesight, an M&A advisory platform built by Talbot West in partnership with Capitalize Network and Tree Ring Digital, uses a neurosymbolic CHAI architecture consisting of multiple capabilities.
In the BizForesight schema, William represents the "neuro" portion of neurosymbolic, while all the other layers are the "symbolic" portions. These symbolic layers counteract the tendency of large language models to play fast and loose with facts and to lose the plot when dealing with large datasets.

Neurosymbolic AI specifically combines neural networks with symbolic reasoning systems to merge learning with logic. Hybrid AI is a broader term that can mean any combination of AI techniques, including mixing different types of neural networks or combining rule-based systems with statistical methods. "Hybrid AI" is therefore a more generic term for ensemble AI deployments. All neurosymbolic systems are hybrid, but not all hybrid AI is neurosymbolic.
Not necessarily. While neurosymbolic systems run two types of processing, the symbolic components often reduce the computational load by constraining the problem space and eliminating invalid options before neural processing. A neurosymbolic system might actually use fewer resources than a massive neural network trying to implicitly learn rules that could be explicitly programmed.
Most likely. You probably don't need to abandon existing neural network investments. A trained neural network can be paired with symbolic components that add reasoning capabilities, constraint checking, or explainability layers. The key is designing the right interfaces between neural and symbolic components and determining how they should interact for your specific use case.
Industries with complex regulations, high-stakes decisions, or deep domain expertise see the greatest value from neurosymbolic AI because of its greater explainability and reliability. Healthcare combines pattern recognition in medical imaging with diagnostic protocols. Financial services merge fraud detection with compliance rules. Manufacturing pairs quality inspection with specifications. Defense and intelligence fuse sensor analysis with mission parameters. Any domain where "why" matters as much as "what" benefits from neurosymbolic approaches.
CHAI neurosymbolic systems handle conflicts through different strategies depending on the use case. Some implementations give symbolic rules veto power over neural suggestions when safety or compliance is critical. Others use confidence scores to weight recommendations. Advanced systems employ a meta-reasoning layer that considers context to resolve conflicts. CHAI implementations can be configured with custom conflict resolution logic specific to your domain requirements.
A minimum viable neurosymbolic system can be as simple as a neural network for classification paired with a rule engine for decision logic. For example, a neural network that identifies customer sentiment combined with if-then rules for routing responses. You don't need massive infrastructure; start with one neural component, one symbolic component, and a clear interface between them.
