Symbolic AI vs machine learning in natural language processing

Meanwhile, the learned visual concepts facilitate learning new words and parsing new sentences. We use curriculum learning to guide searching over the large compositional space of images and language. Extensive experiments demonstrate the accuracy and efficiency of our model on learning visual concepts, word representations, and semantic parsing of sentences. Further, our method allows easy generalization to new object attributes, compositions, language concepts, scenes and questions, and even new program domains.

Despite the long-term advantages of MDE, many businesses and organisations are discouraged from adopting it because of the high initial costs and specialised skills required. Our research is intended to remove these obstacles by enabling general software practitioners to apply MDE techniques, via the use of simplified notations and by providing AI support for MDE processes. Deep neural networks are also very suitable for reinforcement learning, AI models that develop their behavior through numerous trial and error. This is the kind of AI that masters complicated games such as Go, StarCraft, and Dota. Also, some tasks can’t be translated to direct rules, including speech recognition and natural language processing.

AI ‘breakthrough’: neural net has human-like ability to generalize language

During the study phases, the output sequence for one of the study items was covered and the participants were asked to reproduce it, given their memory and the other items on the screen. Corrective feedback was provided, and the participants cycled through all non-primitive study items until all were produced correctly or three cycles were completed. The test phase asked participants to produce the outputs for novel instructions, with no feedback provided (Extended Data Fig. 1b). The study items remained on the screen for reference, so that performance would reflect generalization in the absence of memory limitations. The study and test items always differed from one another by more than one primitive substitution (except in the function 1 stage, where a single primitive was presented as a novel argument to function 1). Some test items also required reasoning beyond substituting variables and, in particular, understanding longer compositions of functions than were seen in the study phase.

Second, it can learn symbols from the world and construct the deep symbolic networks automatically, by utilizing the fact that real world objects have been naturally separated by singularities. Third, it is symbolic, with the capacity of performing causal deduction and generalization. Fourth, the symbols and the links between them are transparent to us, and thus we will know what it has learned or not - which is the key for the security of an AI system. We present the details of the model, the algorithm powering its automatic learning ability, and describe its usefulness in different use cases. The purpose of this paper is to generate broad interest to develop it within an open source project centered on the Deep Symbolic Network (DSN) model towards the development of general AI. Implementations of symbolic reasoning are called rules engines or expert systems or knowledge graphs.

More importantly, this opens the door for efficient realization using analog in-memory computing. Similarly, Allen's temporal interval algebra is a simplification of reasoning about time and Region Connection Calculus is a simplification of reasoning about spatial relationships. Qualitative simulation, such as Benjamin Kuipers's QSIM,[89] approximates human reasoning about naive physics, such as what happens when we heat a liquid in a pot on the stove. We expect it to heat and possibly boil over, even though we may not know its temperature, its boiling point, or other details, such as atmospheric pressure. Cognitive architectures such as ACT-R may have additional capabilities, such as the ability to compile frequently used knowledge into higher-level chunks.

Panel (A) shows the average log-likelihood advantage for MLC (joint) across five patterns (that is, ll(MLC (joint)) - ll(MLC)), with the algebraic target shown here only as a reference. You can see an example of this process in the figure below, where the target and input variables can be seen on the upper left of the interface. Symbolic Regression is a technique that discovers explicit mathematical formulas that connect variables on a dataset. This allows machine-learning problems to be solved in a very elegant and robust way. An example abstraction from JavaScript expressions to OCL is provided in the dataset. This has a training set of 28 paired expression examples, and CGBE produced a correct script of 25 LOC in 3s.
