get frequency elements from 2D vector?

Asked 2022-Apr-10 at 16:26

i try to get frequency elements for 2D vector for example : my vector vector edge { {4, 2, 3}, {4, 5, 6}, {2, 8, 9} }; result: 4 and 2 because appears 2 time in the 2D vector i'm not familiar with c++. my code return only one element "the first frequent element but i need to return evry frequency elemnt in the 2d vector .

my code return only one element "the first frequent element but i need to return evry frequency elemnt in the 2d vector .

Every frequency element is in your occurences variable. Instead of only keeping the arg_max you can print the occurence of each value.

Also note that, because you used a map over an unordered_map you already have the results nicely sorted when you print them.

Method to export Incidence Matrix from Grakn?

Asked 2021-May-22 at 00:58

We often use GraphBLAS for graph processing so we need to use the incidence matrix. I haven't been able to find a way to export this from Grakn to a csv or any file. Is this possible?

There isn't a built-in way to dump data to CSV in Grakn right now. However, we do highly encourage our community to contribute open source tooling for these kinds of tasks! Feel free to chat to use about it on our discord.

As to how it can be done, conceptually it's pretty easy:

SimpleHypergraphs.jl - loading hypergraph from text file

Asked 2021-May-03 at 21:56

I'm using the SimpleHypergraphs.jl library and trying to construct a hypergraph from a text file such as a csv.

For example, I'd like to load a hypergraph from a csv file like this:

The matrix that is passed as a Hypergraph constructor should have elements of type Union{Nothing, T} where T is some numeric type (e.g. Matrix{Union{Float64,Nothing}} rather than just be a Matrix{Float64}.

In SimpleHypegraphs.jl, we use nothing (rather than 0) to represent that a vertex does not belong to a hyperedge since in many hypergraph algorithms/applications it is possible for a vertex to belong to a hyper-edge with a zero weight.

Hence you could read your file with the following code (for reproducibility I put the file content into a text variable):

QUESTION

GraphDB: Node as a property of a relationship

Asked 2020-May-06 at 09:24

I am trying to analyze graphDB as an alternative to RDBMS for a problem domain. Here is the analogy of a problem I am trying to solve.

P:Michael and P:Angela r:like_to_eat G:Apple and G:Bread. G:Apple and G:Bread are r:available_in S:Walmart and S:Whole Foods. So far it's straightforward. Here is an image that I think best expresses the graph.

The problem is when I try to specify that Angela likes Apples from Whole Foods and Bread from Walmart. And Michael likes to eat Apples from Walmart and Bread from Whole Foods. How can I represent something like that in a graph? It sounds like I need the concept of a hypergraph to be able to solve this problem, but I have also heard that any hypergraph problem can be solved with property graph too. Can this be solved using standard graph solutions like Neo4j or CosmosDB? Can someone please help me with this

...

ANSWER

Answered 2020-May-06 at 09:24

Another alternative is to represent "Whole Foods" from "Angela likes Apples from Whole Foods" as a property of the edge "likes to eat", which becomes a real "property graph". Here is the data model:
