If this language model is trained on one corpus (e.g. gutenberg) and applied to another (e.g. brown), it is very likely to encounter out of vocabulary words or unseen ngrams....

Potential GSoC Contribution

This is probably because they don't set the random state. For example: - PMQRTest >> testMPInverse

Priority: Medium
Type: Bug

This would remove the coupling between Collections and Complex numbers (which live in a separate package). Some (perhaps not all) examples include: - PMVector >> isReal - PMMatrix >> isReal...

https://en.wikipedia.org/wiki/Moore%E2%80%93Penrose_inverse A simple (but slightly time-consuming) implementation can be based on SVD: ```st PMMatrix >> pseudoinverse | svd u s v sPseudoinverse | svd := PMSingularValueDecomposition decompose: matrix. u :=...

Priority: Medium
Type: Enhancement

For now, only the small square matrix is used for testing. Other three matrices are commented out. If you uncomment example3 and example4, they fail ```st PMSingularValueDecompositionTest >> setUp super...

Priority: Medium
Type: Bug

The implementation of `PMComplex >> sqrt` was improved in PR #221. However, this implementation still suffers from potential floating point overflow/underflow. This is why I suggest something even more robust...

Priority: Low
Type: Enhancement

I don't know if this is easy to do in practice, but this makes a lot of sense to me: A ComplexNumber is a kind of Number

Because numbers can also be conjugate in a different sense: `5 + 5 sqrt` is conjugate to `5 - 5 sqrt`. https://math.stackexchange.com/questions/3397053/whats-the-correct-definition-of-conjugate-and-do-we-identify-them Also, this message should be implemented by `Number`...
