Mimicking the brain: Deep learning meets vector-symbolic AI

The participants also approved a summary view of all of their responses before submitting. There were six pool options, and the assignment of words and item order were random. One participant was excluded because they reported using an external aid in a post-test survey. On average, the participants spent 5 min 5 s in the experiment (minimum 2 min 16 s; maximum 11 min 23 s). The 3GL code generation tasks we have examined (generation of Java, Kotlin, C, and JavaScript) are representative of typical code generation tasks for 3GL targets in MDE.

However, the strategies can also be used for translation and abstraction cases, as the FOR2LAM case of Sect. We have to take into consideration that increasing the number of CGBE strategies will also impact the performance of CGBE; thus, we do not currently support additional strategies for the above abstraction idioms. Code generators may directly produce target language text from models, i.e., model-to-text approaches (M2T), or produce a model that represents the target code, i.e., model-to-model (M2M) approaches [9, 23]. More recently, text-to-text (T2T) code generation languages have been defined [24].

Symbolic machine learning

In this Article, we provide evidence that neural networks can achieve human-like systematic generalization through MLC—an optimization procedure that we introduce for encouraging systematicity through a series of few-shot compositional tasks (Fig. 1). Our implementation of MLC uses only common neural networks without added symbolic machinery, and without hand-designed internal representations or inductive biases. Instead, MLC provides a means of specifying the desired behaviour through high-level guidance and/or direct human examples; a neural network is then asked to develop the right learning skills through meta-learning21. People are adept at learning new concepts and systematically combining them with existing concepts.

A, During training, episode a presents a neural network with a set of study examples and a query instruction, all provided as a simultaneous input. The study examples demonstrate how to ‘jump twice’, ‘skip’ and so on with both instructions and corresponding outputs provided as words and text-based action symbols (solid arrows guiding the stick figures), respectively. The query instruction involves compositional use of a word (‘skip’) that is presented only in isolation in the study examples, and no intended output is provided. The network produces a query output that is compared (hollow arrows) with a behavioural target.

More complex cases involve re-ordering the subterms of a tree; embedding the source tree as a subpart of the target tree, etc. Vertical splitting and context-sensitive generation are handled by learning separate mappings for each part/case of the transformation. Being able to communicate in symbols is one of the main things that make us intelligent. Therefore, symbols have also played a crucial role in the creation of artificial intelligence. Insofar as computers suffered from the same chokepoints, their builders relied on all-too-human hacks like symbols to sidestep the limits to processing, storage and I/O.

Each approach—symbolic, connectionist, and behavior-based—has advantages, but has been criticized by the other approaches. Symbolic AI has been criticized as disembodied, liable to the qualification problem, and poor in handling the perceptual problems where deep learning excels. In turn, connectionist AI has been criticized as poorly suited for deliberative step-by-step problem solving, incorporating knowledge, and handling planning. Finally, Nouvelle AI excels in reactive and real-world robotics domains but has been criticized for difficulties in incorporating learning and knowledge. During SCAN testing (an example episode is shown in Extended Data Fig. 7), MLC is evaluated on each query in the test corpus. For each query, 10 study examples are again sampled uniformly from the training corpus (using the test corpus for study examples would inadvertently leak test information).

The learning camp attempts to generalize from examples about partial descriptions about the world. The recent adaptation of deep neural network-based methods to reinforcement learning and planning domains has yielded remarkable progress on individual tasks. In pursuit of efficient and we introduce the Schema Network, an object-oriented generative physics simulator capable of disentangling multiple causes of events and reasoning backward through causes to achieve goals.

At the two year mark I’m planning on moving away from machine learning posts into just generally covering artificial intelligence and producing research notes related to a planned set of academic articles. In all these studies, creativity judgments rely on people’s ability and coherence to recognize and judge what is creative or not and to explain their decision along attributes30,31,34. Similarly, in scientific psychological assessments, there is a common practice of establishing correspondence between the concept of a term and behavioral outcomes3,4. Hence, studying the complex associations between judgment and attributes that can potentially be incorporated into numeric predicting patterns4,5,36,39, is intriguing considering that individuals appear to be adept at recognizing creativity. We believe that our results are the first step to direct learning representations in the neural networks towards symbol-like entities that can be manipulated by high-dimensional computing. Such an approach facilitates fast and lifelong learning and paves the way for high-level reasoning and manipulation of objects.

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. Note that an earlier version of memory-based meta-learning for compositional generalization used a more limited and specialized architecture30,65.

To compare humans and machines, we conducted human behavioural experiments using an instruction learning paradigm. MLC also advances the compositional skills of machine learning systems in several systematic generalization benchmarks. Our results show how a standard neural network architecture, optimized for its compositional skills, can mimic human systematic generalization in a head-to-head comparison. The specific procedure of optimizing over many related grammar-based tasks is not developmentally plausible, but there are several ways in which the greater principle—that systematicity can be honed through incentive and practice—has developmental merit.
