This class represents a weighted graph for the purposes
of determining clusters via the Markov Clustering Algorithm.
To initialize an object of this class, pass in a dictionary
which maps pairs (tuples) of vertices to the corresponding weight.
Stores internally both an adjacency list and an adjacency matrix
This is fine as the number of expected vertices is small.

Dataset Summary
The Vault dataset is a comprehensive, large-scale, multilingual parallel dataset that features high-quality code-text pairs derived from The Stack, the largest permissively-licensed source code dataset.
We provide The Vault which contains code snippets from 10 popular programming languages such as Java, JavaScript, Python, Ruby, Rust, Golang, C#, C++, C, and PHP. This dataset provides multiple code-snippet levels, metadata, and 11 docstring styles for enhanced usability and versatility.
Supported Tasks
The Vault can be used for pretraining LLMs or downstream code-text interaction tasks. A number of tasks related to code understanding and geneartion can be constructed using The Vault such as code summarization, text-to-code generation and code search.
Languages
The natural language text (docstring) is in English.
10 programming languages are supported in The Vault: Python, Java, JavaScript, PHP, C, C#, C++, Go, Ruby, Rust
Note: C and Go are not contained in this repo due to the nonexistence of traditional classes in these languages.

Usage
You can load The Vault dataset using datasets library: pip install datasets
from datasets import load_dataset
# Load full class level dataset
dataset = load_dataset("Fsoft-AIC/the-vault-class")
# specific language (e.g. Python)
dataset = load_dataset("Fsoft-AIC/the-vault-class", languages=['Python'])
# dataset streaming
data = load_dataset("Fsoft-AIC/the-vault-class", streaming= True)
for sample in iter(data['train']):
print(sample)
A back up dataset can be downloaded in azure storage. See Download The Vault from Azure blob storage.
