Symbolic Reasoning In Artificial Intelligence

symbolic reasoning

The core idea is that each neuron makes a specialized distinction, either signifying a specific concept or differentiating between two opposing concepts. In other words, one type of neuron makes the distinction “like A” versus “not like A,” and the other kind of neuron makes the distinction “more like A” versus “more like B.”. When creating complex expressions, we debug them by using the Trace expression, which allows us to print out the applied expressions and follow the StackTrace of the neuro-symbolic operations. Combined with the Log expression, which creates a dump of all prompts and results to a log file, we can analyze where our models potentially failed. Perhaps one of the most significant advantages of using neuro-symbolic programming is that it allows for a clear understanding of how well our LLMs comprehend simple operations. Specifically, we gain insight into whether and at what point they fail, enabling us to follow their StackTraces and pinpoint the failure points.


External symbolic notations need not be translated into internal representational structures, but neither does all mathematical reasoning occur by manipulating perceived notations on paper. Rather, complex visual and auditory processes such as affordance learning, perceptual pattern-matching and perceptual grouping of notational structures produce simplified representations of the mathematical problem, simplifying the task faced by the rest of the symbolic reasoning system. Perceptual processes exploit the typically well-designed features of physical notations to automatically reduce and simplify difficult, routine formal chores, and so are themselves constitutively involved in the capacity for symbolic reasoning. On our view, therefore, much of the capacity for symbolic reasoning is implemented as the perception, manipulation and modal and cross-modal representation of externally perceived notations. Perceptual Manipulations Theory suggests that most symbolic reasoning emerges from the ways in which notational formalisms are perceived and manipulated.

The Rise and Fall of Symbolic AI

René Descartes, a mathematician, and philosopher, regarded thoughts themselves as symbolic representations and Perception as an internal process. Normal forms are usually preferred in computer algebra for several reasons. Firstly, canonical forms may be more costly to compute than normal forms. For example, to put a polynomial in canonical form, one has to expand every product through distributivity, while it is not necessary with a normal form (see below). Secondly, it may be the case, like for expressions involving radicals, that a canonical form, if it exists, depends on some arbitrary choices and that these choices may be different for two expressions that have been computed independently.

In our case, neuro-symbolic programming enables us to debug the model predictions based on dedicated unit tests for simple operations. To detect conceptual misalignments, we can use a chain of neuro-symbolic operations and validate the generative process. Although not a perfect solution, as the verification might also be error-prone, it provides a principled way to detect conceptual flaws and biases in our LLMs. SymbolicAI’s API closely follows best practices and ideas from PyTorch, allowing the creation of complex expressions by combining multiple expressions as a computational graph.

Knowledge representation and reasoning

In fact, rule-based AI systems are still very important in today’s applications. Many leading scientists believe that will continue to remain a very important component of artificial intelligence. Furthermore, we interpret all objects as symbols with different encodings and have integrated a set of useful engines that convert these objects into the natural language domain to perform our operations. Basic operations in Symbol are implemented by defining local functions and decorating them with corresponding operation decorators from the symai/core.py file, a collection of predefined operation decorators that can be applied rapidly to any function. Using local functions instead of decorating main methods directly avoids unnecessary communication with the neural engine and allows for default behavior implementation.

However, Transformer models are opaque and do not yet produce human-interpretable semantic representations for sentences and documents. Instead, they produce task-specific vectors where the meaning of the vector components is opaque. First of all, every deep neural net trained by supervised learning combines deep learning and symbolic manipulation, at least in a rudimentary sense. Because symbolic reasoning encodes knowledge in symbols and strings of characters. In supervised learning, those strings of characters are called labels, the categories by which we classify input data using a statistical model.

A third student learns by asking questions and answering questions together in those scenes. Scientists may eventually want to combine the two components in a more advanced form known as neuro-symbolic AI. AI will be able to learn and reason while performing a wide range of tasks without extensive training. Some authors distinguish computer algebra from symbolic computation using the latter name to refer to kinds of symbolic computation other than the computation with mathematical formulas. Some authors use symbolic computation for the computer science aspect of the subject and “computer algebra” for the mathematical aspect.[2] In some languages the name of the field is not a direct translation of its English name. Typically, it is called calcul formel in French, which means “formal computation”.
