CHAPTER

Neural Networks and Compositionality

Compositionality is that the meaning of a complex expression is fully determined by its structure and the meanings of its constituents. Once we fix what the parts mean and how they are put together, we have no more lee way regarding meaning of the whole. This doesn't just apply to expressions; this also applies to planning and reasoning. It's only possible with an algebraic approach to semantics and planit achieved with symbolic manipulation. That's why neural networks cannot do basic arithmetic. They cannot represent inten al, which is to say, infinite objects. The important thing to realize is the only way to represent infinite objects in a finite way is using quantification or logic over typed symbolic structures.
