Definitions
- the present invention relates to a mechanism for detecting anomalies in a bank transaction flow. It applies in particular to the detection of fraud.
- the model works the opposite: the input of the network is a word wi and Word2Vec predicts the context around this word: wi-2, wi-1, wi + 1, wi 2.
- Word2Vec is very fast and can be further accelerated using parallel learning techniques.
- training on Wikipedia's corpus can take around 90 minutes with a personal computer equipped with a quad-core processor Intel brand running at 4x3.4 GHz, and a memory of 16 GB.
- the node succ (x) of the node x is chosen randomly and uniformly equally among the adjacent nodes, that is to say with a uniform probability equal to 1 / Edges0f (x), with "EdgesOf (x)" a function returning the number of links of the node x, that is to say the number of links in the vector vk.
