Abstract: Methods and systems for predictive analysis are disclosed, A predictive analysis method comprises: receiving a set of predictor variables as an input feature vector comprising a plurality of features; projecting each feature of the input feature vector onto a dense vector representation to obtain a set of embedding vectors presenting the input feature vector in an embedding space; calculating a set of interacted vectors, each interacted vector being an element-wise product of two embedding vectors of the set of embedding vectors; performing a weight sum over the interacted vectors, the weighted sum being weighted by a plurality of attention scores each corresponding to an interaction between a pair of features of the feature vector; and projecting the weighed sum to obtain a prediction score.
