Vidai: Neural Mathematical Parsing Demo

Work in Progress: This demo showcases a novel neuro-symbolic architecture. Simple expressions work well; complex expressions need more training data.

The Approach

Vidai (Tamil for "answer") uses transformers for what they're good at: pattern recognition and sequence transformation. Instead of asking a model to "learn" that 7 × 8 = 56 from text, Vidai learns to recognize the tree structure inherent in mathematical expressions.

ContextEncoder: Recognizes expression structure with tree-depth embeddings
SymbolicParserDecoder: Outputs prefix notation that explicitly encodes the tree
SymPy: Handles exact computation deterministically

x^2 + 3*y becomes + ** x 2 * 3 y (a tree with + at root).

What Works

Expression Type	Status
Simple arithmetic: `3 + 5 * 2`	✅ Works
Parenthesized: `(x^2) + (3*y)`	✅ Works
Single functions: `sin(x)`, `sqrt(16)`	✅ Works
Complex without parens	⚠️ Needs more training data
Deep nesting (3+ levels)	⚠️ Needs more training data
