Session-level Language Modeling for Conversational Speech (D18-1)
Copied to clipboard
| Challenge: | Xiong et al., 2017) generalizes language models for conversational speech recognition . recurrent neural networks (RNNs) read a list of words sequentially and predict the next word at each position. |
| Approach: | They propose to generalize language models for conversational speech recognition to capture conversation-level phenomena such as adjacency pairs, lexical entrainment, and topical coherence. |
| Outcome: | The proposed model reduces perplexity and improves word error rate over standard models in the conversational telephone speech domain. |

| Challenge: | a new approach to customer support is proposed to integrate large language models with a framework designed to navigate the complexities of Airbnb customer support operations. |
| Approach: | They propose a method for integrating Large Language Models with a framework designed to navigate the complexities of Airbnb customer support operations. |
| Outcome: | The proposed approach is cost-effective and improves customer support performance . it also allows human agents to focus on more complex issues, the authors show . |
RelayAttention for Efficient Large Language Model Serving with Long System Prompts (2024.acl-long)
Copied to clipboard
| Challenge: | a long system prompt causes throughput/latency bottlenecks as the cost of generating the next token increases w.r.t the sequence length. |
| Approach: | They propose an attention algorithm that reads hidden state from DRAM exactly once for a batch of input tokens. |
| Outcome: | The proposed algorithm reduces the need for redundant memory accesses in existing algorithms. |
