kandi X-RAY | milner Summary
Lazy ML with Calculus of Communicating Systems (introduced by Robin Milner). Язык который предназначен для образовательных целей, что бы можно было "на пальцах" показать, как создать функциальный язык основанный на λ-исчислении. Для перчинки в язык инкапсулированы ленивость и исчисление процессов, предложенное Робином Милнером.

QUESTION
I am trying to combine multiple array columns into one with distinct elements and then get a count of distinct elements. How can I do something like that in postgres?
...ANSWER
Answered 2022-Jan-19 at 23:03Why do you (want to) use arrays? That's not needed. Simply have a derived table using UNION
, which eliminates duplicates, GROUP BY
the name
and use count()
.
QUESTION
I have a parent table like this:
clubs
id name budget 1 Arsenal 90 2 Chelsea 150 3 Man City 135 4 Man Utd 140 5 Tottenham 87And a child table like this
players
id club_id name position 1 3 Grealish LM 2 3 Sterling LW 3 3 Haaland ST 4 1 Dybala ST 5 1 Casemiro DM 6 4 Fred DM 7 2 Mbappe ST 8 2 Hazard LW 9 4 Varane DMThe club_id is the foreign key that refer to the clubs table id column

QUESTION
I'm trying to implement language with type inference based on Hindley-Milner algorithm. But I don't know how to infer types for recursive functions:
...ANSWER
Answered 2021-Apr-25 at 15:13In your case, you need to infer the type of h
and generalize it to a polytype before inferring the types for f
and g
.
If I remember correctly, the strategy Haskell uses for such cases is to compute the dependency graph (which identifier depends on which identifiers), and then to separate the graph into strongly connected components. This provides a kind of ordering among definitions, which are then handled accordingly.
For instance, in

I'm reading a functional programming tutorial called Professor Frisby's Mostly Adequate Guide to Functional Programming, the author gives an introduction to Hindley-Milner
and several examples about it, one of them being:
ANSWER
Answered 2021-Apr-14 at 08:27I went through this tutorial myself and I think generally functions are assumed to be curried so f
being b -> a -> b
is perhaps counter-intuitive but not necessarily wrong AFAIK. (Take everything I say with a pinch of salt; I'm not an expert ;)
However the parentheses around f
itself in the reduce
signature gives an important clue to the reader (at least to the JavaScript reader) that f
is a function:

I have created a HashMap
I am trying to print the key alongside the elements of the list at each value.
So for instance the first line should print
...ANSWER
Answered 2021-Mar-01 at 00:01Maybe a better approach would be if we can use for loop when we get the Key value after that we go the for the HashMap values that are an array of String
QUESTION
AFAIK, unification used in the Hindley-Milner type system can be generalized to unify higher-kinded types by allowing type vars in constructor position and by relaxing the arity constraint in such cases:
...ANSWER
Answered 2021-Feb-01 at 20:23This isn't really my wheelhouse, but I can maybe offer a very general answer.
The fundamental difference is that generalized HM treats unification as a purely syntactic matching process aimed at producing a unique match, while an HOU algorithm involves a semantic consideration of the types/kinds (as terms/types in a typed lambda calculus) and a systematic search through a tree of possible unifications, including consideration of alternative unifications at interior nodes.
(The reason for the limitations of the HM approach is that for first-order types, purely syntactic matching is basically equivalent to a semantic consideration of the types and a systematic search through possibly unifications.)
Anyway, take a trivial higher-order unification:

aw_data = {'first_name': ['Jason', 'Molly', 'Tina', 'Jake', 'Amy'],
'last_name': [" 'Miller' "," 'Jacobson' ", 'Ali', 'Milner', 'Cooze'],
'age': [42, 52, 36, 24, 73],
'preTestScore': [4, 24, 31, 2, 3],
'postTestScore': [25, 94, 57, 62, 70]}
df = pd.DataFrame(raw_data, columns = ['first_name', 'last_name', 'age', 'preTestScore', 'postTestScore'])

EDIT: This is has been identified as a bug here.
I am trying to make a Google Meet along with a new calendar event. However, for some reason the returning event does not include any conferenceData, not even one with status fail.
Here is my code. I have omitted the authentication step as I do not get an authentication error.

QUESTION
I'm trying to build a batch generator which takes a large Pandas DataFrame as input and output as a given number of rows (batch_size). I practiced on the smaller dataframe with 10 rows to get it work. I have trouble with the generator function where the for loop below works well on the practice dataframe, and spits out the designated batch size:
...ANSWER
Answered 2020-May-21 at 10:22Create an iterator on the result of calling your Generator and next()
that iterator. Else you recreate new Generator "states" for the generator which might have the same "first line" if you provide a seed.
After fixing the indentation problems it works as it should:
