Symbolic AI v s Non-Symbolic AI, and everything in between? by Rhett D’souza DataDrivenInvestor
We’ve been working for decades to gather the data and computing power necessary to realize that goal, but now it is available. Neuro-symbolic models have already beaten cutting-edge deep learning models in areas like image and video reasoning. Furthermore, compared to conventional models, they have achieved good accuracy with substantially less training data. This article helps you to understand everything regarding Neuro Symbolic AI. Deep reinforcement learning (DRL) brings the power of deep neural networks the generic task of trial-and-error learning, and its effectiveness has been convincingly demonstrated on tasks such as Atari video games and the game of Go. However, contemporary DRL systems inherit a number of shortcomings from the current generation of deep learning techniques.
- Symbolic AI involves the explicit embedding of human knowledge and behavior rules into computer programs.
- Symbolic AI algorithms are used in a variety of applications, including natural language processing, knowledge representation, and planning.
- When you have huge amounts of carefully curated data, you can achieve remarkable things with them, such as superhuman accuracy and speed.
Naturally, research into all types of AI rarely comes to a standstill, if at all. But we’re definitely going to be seeing a keen focus on expanding the knowledge graph and automating ML along with other methods, because enterprises are now under pressure to quickly consume massive amounts of data and at a lower cost too. Each approach may be used to target the problem from a unique angle, and through varying models, evaluate and solve the problem in a multi-contextual way.

The static_context influences all operations of the current Expression sub-class. The sym_return_type ensures that after evaluating an Expression, we obtain the desired return object type. It is usually implemented to return the current type but can be set to return a different type.
Another approach is for symbolic reasoning to guide the neural networks’ generative process and increase interpretability. Neuro-symbolic programming is an artificial intelligence and cognitive computing paradigm that combines the strengths of deep neural networks and symbolic reasoning. In this line of effort, deep learning systems are trained to solve problems such as term rewriting, planning, elementary algebra, logical deduction or abduction or rule learning. These problems are known to often require sophisticated and non-trivial symbolic algorithms. Attempting these hard but well-understood problems using deep learning adds to the general understanding of the capabilities and limits of deep learning. It also provides deep learning modules that are potentially faster (after training) and more robust to data imperfections than their symbolic counterparts.
Four Ways That Machine Learning Can Improve Business Processes
For instance, if one’s job application gets rejected by an AI, or a loan application doesn’t go through. Neuro-symbolic AI can make the process transparent and interpretable by the artificial intelligence engineers, and explain why an AI program does what it does. Symbolic AI uses tools such as Logic programming, production rules, semantic nets, and frames, and it developed applications such as expert systems.

“The general trend in AI and in computing as a whole, towards further and further automation and replacing hard-coded approaches with automatically learned ones, seems to be the way to go,” she added. However, their utility breaks down once they’re prompted to adapt to a more general task. For instance, take a look at the following picture of a “Teddy Bear” — or at least in the interpretation of a sophisticated modern AI. When you have huge amounts of carefully curated data, you can achieve remarkable things with them, such as superhuman accuracy and speed.
Complex problem solving through coupling of deep learning and symbolic components. Coupled neuro-symbolic systems are increasingly used to solve complex problems such as game playing or scene, word, sentence interpretation. In a different line of work, logic tensor networks in particular have been designed to capture logical background knowledge to improve image interpretation, and neural theorem provers can provide natural language reasoning by also taking knowledge bases into account. Coupling may be through different methods, including the calling of deep learning systems within a symbolic algorithm, or the acquisition of symbolic rules during training. Very tight coupling can be achieved for example by means of Markov logics.
Symbolic AI algorithms are used in a variety of AI applications, including knowledge representation, planning, and natural language processing. Symbolic AI involves the explicit embedding of human knowledge and behavior rules into computer programs. The practice showed a lot of promise in the early decades of AI research.
It includes tens of millions of pieces of information entered by humans in a way that can be used by software for quick reasoning. Symbolic AI, also known as classical AI or rule-based AI, is a subfield of artificial intelligence that focuses on the manipulation of symbols and the use of logical reasoning to solve problems. This approach to AI is based on the idea that intelligence can be achieved by representing knowledge as symbols and performing operations on those symbols. The power of neural networks is that they help automate the process of generating models of the world.

A key idea of the SymbolicAI API is code generation, which may result in errors that need to be handled contextually. In the future, we want our API to self-extend and resolve issues automatically. We propose the Try expression, which has built-in fallback statements and retries an execution with dedicated error analysis and correction. The expression analyzes the input and error, conditioning itself to resolve the error by manipulating the original code. Otherwise, this process is repeated for the specified number of retries.
The most frequent input function is a dot product of the vector of incoming activations. Next, the transfer function computes a transformation on the combined incoming signals to compute the activation state of a neuron. The learning rule is a rule for determining how weights of the network should change in response to new data. Lastly, the model environment is how training data, usually input and output pairs, are encoded.
All operations are executed in an input-driven fashion, thus sparsity and dynamic computation per sample are naturally supported, complementing recent popular ideas of dynamic networks and may enable new types of hardware accelerations. We experimentally show on CIFAR-10 that it can perform flexible visual processing, rivaling the performance of ConvNet, but without using any convolution. Furthermore, it can generalize to novel rotations of images that it was not trained for. Recent approaches towards solving these challenges include representing symbol manipulation as operations performed by neural network [53,64], thereby enabling symbolic inference with distributed representations grounded in domain data.
We typically use predicate logic to define these symbols and relations formally – more on this in the A quick tangent on Boolean logic section later in this chapter. The primary motivation behind Artificial Intelligence (AI) systems has always been to allow computers to mimic our behavior, to enable machines to think like us and act like us, to be like us. However, the methodology and the mindset of how we approach AI has gone through several phases throughout the years. “As impressive as things like transformers are on our path to natural language understanding, they are not sufficient,” Cox said.
Researchers began investigating newer algorithms and frameworks to achieve machine intelligence. Furthermore, the limitations of Symbolic AI were becoming significant enough not to let it reach higher levels of machine intelligence and autonomy. In the following subsections, we will delve deeper into the substantial limitations and pitfalls of Symbolic AI. The Second World War saw massive scientific contributions and technological advancements. Innovations such as radar technology, the mass production of penicillin, and the jet engine were all a by-product of the war.
Why did symbolic AI fail?
Since symbolic AI can't learn by itself, developers had to feed it with data and rules continuously. They also found out that the more they feed the machine, the more inaccurate its results became.
Consequently, we develop operations that manipulate these symbols to construct new symbols. Each symbol can be interpreted as a statement, and multiple statements can be combined to formulate a logical expression. In time, and with sufficient data, we can gradually transition from general-purpose LLMs with zero and few-shot learning capabilities to specialized, fine-tuned models designed to solve specific problems (see above). This strategy enables the design of operations with fine-tuned, task-specific behavior.

Is NLP symbolic AI?
One of the many uses of symbolic AI is with NLP for conversational chatbots. With this approach, also called “deterministic,” the idea is to teach the machine how to understand languages in the same way we humans have learned how to read and how to write.
