Cheatsheet of Latex Code for Graph Neural Network(GNN) Equations
rockingdingo 20220717 #graph neural network #gnn #gcn #gat #graphsageIn this blog, we will summarize the latex code of equations of Graph Neural Network(GNN) models, which are useful as quick reference for your research. For common notation, we denote G=(V,E) as the graph. V as the set of nodes with size V=N, and E as the set of N_e edges as E = N_e. A is denoted as the adjacency matrix. For each node v, we use h_v and o_v as hidde state and output vector of each node.

Cheatsheet of Latex Code for Transfer Learning Equations
rockingdingo 20220717 #machine learning #transfer learning #domain adaptation #DomainAdversarial Neural NetworksIn this blog, we will summarize the latex code of most fundamental equations of transfer learning(TL). Different from multitask learning, transfer learning models aims to achieve the best performance on target domain (minimized target domain test errors), not the performance of source domain. Typical transfer learning methods including domain adaptation(DA), feature subspace alignment, etc. In this post, we will dicuss more details of TL equations, including many subareas like domain adaptation, Hdivergence, DomainAdversarial Neural Networks(DANN), which are useful as quick reference for your research.

Deep Candidate Generation (DeepMatch) Algorithm in recommendation
rockingdingo 20210725 #deep candidate generation #deepmatch #recommendation #vector retrievalIn this post, we will talk about some realworld applications of deep candidates generation (vectorretrieval) models in the matching stage of recommendation scenario. Commercial recommendation system will recommend tens of millions of items to each user. And the recommendation process usually consists of two stages: The first stage is the candidate generation(matching) stage, a few hundred candidates are selected from the pool of all candidate items. The second stage is the ranking stage in which hundreds of items are ranked and sorted by the ranking score. Then the top rated items are displayed to users.
