Symbolic AI: The key to the thinking machine

2208 11561 Deep Symbolic Learning: Discovering Symbols and Rules from Perceptions

For example, they require very large datasets to work effectively, entailing that they are slow to learn even when such datasets are available. Moreover, they lack the ability to reason on an abstract level, which makes it difficult to implement high-level cognitive functions such as transfer learning, analogical reasoning, and hypothesis-based reasoning. Finally, their operation is largely opaque to humans, rendering them unsuitable for domains in which verifiability is important. In this paper, we propose an end-to-end reinforcement learning architecture comprising a neural back end and a symbolic front end with the potential to overcome each of these shortcomings. As proof-of-concept, we present a preliminary implementation of the architecture and apply it to several variants of a simple video game. We show that the resulting system – though just a prototype – learns effectively, and, by acquiring a set of symbolic rules that are easily comprehensible to humans, dramatically outperforms a conventional, fully neural DRL system on a stochastic variant of the game.

Extract the datasets to this directory, Feynman datasets should be in datasets/feynman/, and PMLB datasets should be in datasets/pmlb/. Enjoy this sweet milestone and encourage pretend play when you can — all too quickly they’ll trade that pasta strainer hat for real-life worries. Your child will start to use one object to represent a different object. That’s because they can now imagine an object and don’t need to have the concrete object in front of them.

Additional variety was produced by shuffling the order of the study examples, as well as randomly remapping the input and output symbols compared to those in the raw data, without altering the structure of the underlying mapping. The models were trained to completion (no validation set or early stopping). This architecture involves two neural networks working together—an encoder transformer to process the query input and study examples, and a decoder transformer to generate the output sequence. Both the encoder and decoder have 3 layers, 8 attention heads per layer, input and hidden embeddings of size 128, and a feedforward hidden size of 512.

We then apply our method to a non-trivial cosmology example-a detailed dark matter simulation-and discover a new analytic formula which can predict the concentration of dark matter from the mass distribution of nearby cosmic structures. The symbolic expressions extracted from the GNN using our technique also generalized to out-of-distribution data better than the GNN itself. Our approach offers alternative directions for interpreting neural networks and discovering novel physical principles from the representations they learn. The advantage of neural networks is that they can deal with messy and unstructured data. Instead of manually laboring through the rules of detecting cat pixels, you can train a deep learning algorithm on many pictures of cats.

More advanced knowledge-based systems, such as Soar can also perform meta-level reasoning, that is reasoning about their own reasoning in terms of deciding how to solve problems and monitoring the success of problem-solving strategies. Research shows that there’s a connection between symbolic play and a mother’s response. The more actions a child carries out, the more the contact, smiles, and touches the child — and then, the more the child plays. It’s part of a great cycle, so start playing and give your child a head start on gaining valuable skills. When we write letters and numbers, we’re using symbols for what we want to convey. When children are engaged in symbolic play, they’re practicing this very concept.

On COGS, MLC achieves an error rate of 0.87% across the 18 types of lexical generalization. Without the benefit of meta-learning, basic seq2seq has error rates at least seven times as high across the benchmarks, despite using the same transformer architecture. However surface-level permutations were not enough for MLC to solve the structural generalization tasks in the benchmarks. MLC fails to handle longer output sequences (SCAN length split) as well as novel and more complex sentence structures (three types in COGS), with error rates at 100%. Such tasks require handling ‘productivity’ (page 33 of ref. 1), in ways that are largely distinct from systematicity. People are adept at learning new concepts and systematically combining them with existing concepts.

The role of symbols in artificial intelligence

In practice, however, his model requires the teacher to be actively involved in lessons; providing cognitive scaffolding which will facilitate learning on the part of the student. Discovery is not just an instructional technique, but an important learning outcome in itself. Schools should help learners develop their own ability to find the “recurrent regularities” in their environment.
