1. **Definition**: Large-scale Information Network Embedding (LINE) is a graph embedding technique used in machine learning to represent nodes in large-scale networks [43] [64].

2. **Purpose**: LINE aims to capture the structural properties of networks, facilitating tasks such as link prediction and node classification [43].

3. **Methodology**: LINE employs a two-step process - first, it preserves the first-order proximity (closeness) between connected nodes, and second, it maintains the second-order proximity (neighborhood similarity) in the embedding space [43] [64].

4. **Applications**: LINE finds applications in various domains, including computational biology, social network analysis, and recommendation systems [43] [76] [85].

5. **Implementation**: There are TensorFlow implementations available for LINE [78].

6. **Challenges and Advances**: Ongoing research explores enhancements and challenges in network embedding, with advancements like context-aware embedding and decentralized frameworks [59] [83].

7. **Relevance**: Understanding network embeddings like LINE is crucial for improving the efficiency of machine learning models on large-scale graphs [43] [64].
