normalize

L2-normalization (scaling to unit euclidean length):
the norm of each vector in the vector space will be normalized to 1.
It is necessary for any linear operation of word vectors.
R code:<ul>
<li>Vector: <code>vec / sqrt(sum(vec^2))</code></li>
<li>Matrix: <code>mat / sqrt(rowSums(mat^2))</code></li>
</ul>

An integrative toolbox of word embedding research that provides:
(1) a collection of 'pre-trained' static word vectors in the '.RData'
compressed format <https://psychbruce.github.io/WordVector_RData.pdf>;
(2) a series of functions to process, analyze, and visualize word vectors;
(3) a range of tests to examine conceptual associations, including
the Word Embedding Association Test <doi:10.1126/science.aal4230>
and the Relative Norm Distance <doi:10.1073/pnas.1720347115>,
with permutation test of significance;
(4) a set of training methods to locally train (static) word vectors
from text corpora, including 'Word2Vec' <arXiv:1301.3781>,
'GloVe' <doi:10.3115/v1/D14-1162>, and 'FastText' <arXiv:1607.04606>;
(5) a group of functions to download 'pre-trained' language models
(e.g., 'GPT', 'BERT') and extract contextualized (dynamic) word vectors
(based on the R package 'text').
