Towards Expectation-Maximization by SQL in RDBMS [article]

Kangfei Zhao, Jeffrey Xu Yu, Yu Rong, Ming Liao, Junzhou Huang
2021 arXiv   pre-print
In this paper, we provide an SQL solution that has the potential to support different machine learning modelings.  ...  It is important to note that the SQL'99 recursion cannot be used to handle such a while-loop since the M-step is non-monotonic.  ...  We show that users can build model-based view by SQL recursive query with limited enhancement and the support of vector/matrix data type. Model-based View in RDBMS.  ...

Evaluation of Logic Programs with Built-Ins and Aggregation: A Calculus for Bag Relations [article]

Matthew Francis-Landau and Tim Vieira and Jason Eisner
2020 arXiv   pre-print
We present a scheme for translating logic programs, which may use aggregation and arithmetic, into algebraic expressions that denote bag relations over ground terms of the Herbrand universe.  ...  To evaluate queries against these relations, we develop an operational semantics based on term rewriting of the algebraic expressions.  ...  We focus on how our term rewriting approach is able to handle the neural network example (lines 6-14) .  ...
