Code Generation by Example Using Symbolic Machine Learning SN Computer Science

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. Creativity is a compelling yet elusive phenomenon, especially when manifested in visual art, where its evaluation is often a subjective and complex process. Understanding how individuals judge creativity in visual art is a particularly intriguing question. Conventional linear approaches often fail to capture the intricate nature of human behavior underlying such judgments.

Thus, the search for mappings which are consistent with a given set of examples can be restricted to those mappings which are plausible for code generation. Symbolic AI’s adherents say it more closely follows the logic of biological intelligence because it analyzes symbols, not just data, to arrive at more intuitive, knowledge-based conclusions. It’s most commonly used in linguistics models such as natural language processing (NLP) and natural language understanding (NLU), but it is quickly finding its way into ML and other types of AI where it can bring much-needed visibility into algorithmic processes. And unlike symbolic AI, neural networks have no notion of symbols and hierarchical representation of knowledge. This limitation makes it very hard to apply neural networks to tasks that require logic and reasoning, such as science and high-school math.

Machine learning benchmarks

Natural language understanding, in contrast, constructs a meaning representation and uses that for further processing, such as answering questions. Programs were themselves data structures that other programs could operate on, allowing the easy definition of higher-level languages. B.M.L. collected and analysed the and implemented the models, and wrote the initial draft of the Article.

Employing statistical learning, this investigation presents the first attribute-integrating quantitative model of factors that contribute to creativity judgments in visual art among novice raters. Our research represents a significant stride forward building the groundwork for first causal models for future investigations in art and creativity research and offering implications for diverse practical applications. Beyond enhancing comprehension of the intricate interplay and specificity of attributes used in evaluating creativity, this work introduces machine learning as an innovative approach in the field of subjective judgment. The Symbolic AI paradigm led to seminal ideas in search, symbolic programming languages, agents, multi-agent systems, the semantic web, and the strengths and limitations of formal knowledge and reasoning systems. The interpretation grammars that define each episode were randomly generated from a simple meta-grammar. An example episode with input/output examples and corresponding interpretation grammar (see the ‘Interpretation grammars’ section) is shown in Extended Data Fig.

2, this model predicts a mixture of algebraic outputs, one-to-one translations and noisy rule applications to account for human behaviour. A standard transformer encoder (bottom) processes the query input along with a set of study examples (input/output pairs; examples are delimited by a vertical line (∣) token). The standard decoder (top) receives the encoder’s messages and produces an output sequence in response. After optimization on episodes generated from various grammars, the transformer performs novel tasks using frozen weights.

The technology actually dates back to the 1950s, says expert.ai’s Luca Scagliarini, but was considered old-fashioned by the 1990s when demand for procedural knowledge of sensory and motor processes was all the rage. Now that AI is tasked with higher-order systems and data management, the capability to engage in logical thinking and knowledge representation is cool again. But symbolic AI starts to break when you must deal with the messiness of the world. For instance, consider computer vision, the science of enabling computers to make sense of the content of images and video. Say you have a picture of your cat and want to create a program that can detect images that contain your cat.

LLMs can’t self-correct in reasoning tasks, DeepMind study finds

At this point, I should probably go look at all the general conceptual models of the machine learning space and see how close I am to reaching comprehensive coverage. I jumped over into Google Trends and took a look at what topics are bubbling to the surface [0]. Valence likely emerges from the presented content in conjunction with attributes such as symbolism, abstraction, and imaginativeness (40, see Fig. 3b for potential associations). However, emotionality and valence (see Fig. S3 in Supplementary Information) showed very low correlations with the other attributes in general.

For visual processing, each “object/symbol” can explicitly package common properties of visual objects like its position, pose, scale, probability of being an object, pointers to parts, etc., providing a full spectrum of interpretable visual knowledge throughout all layers. It achieves a form of “symbolic disentanglement”, offering one solution to the important problem of disentangled representations and invariance. Basic computations of the network include predicting high-level objects and their properties from low-level objects and binding/aggregating relevant objects together.

We have described a process for synthesising code generator transformations from datasets of text examples. The approach uses symbolic machine learning to produce explicit specifications of the code generators. Thus, a developer of a template-based code generator needs to understand the source language metamodel, the target language syntax, and the template language. These three languages are intermixed in the template texts, with delimiters used to separate the syntax of different languages. The concept is similar to the use of JSP to produce dynamic Web pages from business data. Figure 1 shows an example of an EGL script combining fixed template text and dynamic content, and the resulting generated code.

Due to the difference of prediction mechanisms of white-box models (i.e., mechanical-properties-based models) and black-box models (i.e., data-driven-based models), so far, they are considered as the independent approaches for resistance prediction [31]. In previous studies, white-box models are welcomed due to the explicit prediction mechanisms, whereas black-box models due to the superior prediction performances. As an intermediate model with these advantages, grey-box models bridge the gap between white and black-models elegantly, and gain the popularity in the latest studies [32,33]. Herein, a machine-learning-based symbolic regression technique, namely genetic programming (GP), is adopted to develop a grey-box prediction model for punching shear resistance of FRP-reinforced concrete slabs.

This test episode probes the understanding of ‘Paula’ (proper noun), which just occurs in one of COGS’s original training patterns. Each step is annotated with the next re-write rules to be applied, and how many times (e.g., 3 × , since some steps have multiple parallel applications). For each SCAN split, both MLC and basic seq2seq models were optimized for 200 epochs without any early stopping. For COGS, both models were optimized for 300 epochs (also without early stopping), which is slightly more training than the extended amount prescribed in ref. 67 for their strong seq2seq baseline. This more scalable MLC variant, the original MLC architecture (see the ‘Architecture and optimizer’ section) and basic seq2seq all have approximately the same number of learnable parameters (except for the fact that basic seq2seq has a smaller input vocabulary).

Recently new symbolic regression tools have been developed, such as TuringBot [3], a desktop software for symbolic regression based on simulated annealing. The promise of deriving physical laws from data with symbolic regression has also been revived with a project called Feynman AI, lead by famous physicist Max Tegmark [4]. In addition to symbolism, emotionality, and imaginativeness, also the attributes complexity, abstractness, and valence predicted creativity judgments to a lesser extent, all showing a positive association with judged creativity (see Fig. S1a–c in Supplementary Information). It is one form of assumption, and a strong one, while deep neural architectures contain other assumptions, usually about how they should learn, rather than what conclusion they should reach.
