Object2Vec Algorithm
Object2Vec Algorithm is an Unsupervised Learning algorithm. The algorithm compares pairs of data points and preserves the semantics of the relationship between the pairs. The algorithm creates embeddings that can be used by other algorithms downstream. The embeddings are low-dimensional dense embeddings of high-dimensional objects. Object2Vec can be used for product search, item matching and customer profiling.
Customer profiling is used in personalization and recommendation systems. Object2Vec Algorithm can deliver predictions that are more accurate than manual methods based on customer attributes such as age or gender.
