Fellow
hacker,
I am new comer to postgres development community. Currently, I
am implementing tightly coupled machine classifiers within postgres. The
grammer looks like Train Parameter_list (class1,class2,class3...). I have
two major problems right now.
1. Train is a statement and it is
suppose to return some parameters in the form of a query. (To be used by a
classifier later.) How can I return a Query with self specified column
name and data vectors?
2. class1, class2 are all supposed to be
relations/query result. But what is a proper container to hold them. I
found var_list to be a good candidate as it can contain unconstrained
number of var_values. But var_values are of constant types. Can I just add
query as a constant? Anyone had this kind of implementing
experience?
Thanks, John
