CS 7643 Quiz 4| 41 Latest Questions and Answers| | 100% Correct | 2025 Update Embedding - Correct Answer A learned map from entities to vectors that encodes similarity Graph Embedding - Correct Answer Optimize the objective that connected nodes have more similar embeddings than unconnected nodes. Task: convert nodes to vectors - effectively unsupervised learning where nearest neighbors are similar - these learned vectors are useful for downstream tasks Multi-layer Perceptron (MLP) pain points for NLP - Correct Answer - Cannot easily support variable-sized sequences as inputs or outputs - No inherent temporal structure - No practical way of holding state - The size of the network grows with the maximum allowed size of the input or output sequences Truncated Backpropagation through time - Correct Answer - Only backpropagate a RNN through T time steps
