r/LanguageTechnology

Analysis

This post highlights a common challenge in creating QnA datasets: validating the accuracy of automatically generated question-answer pairs, especially when dealing with large datasets. The author's approach of using cosine similarity on embeddings to find matching answers in summaries often leads to false negatives. The core problem lies in the limitations of relying solely on semantic similarity metrics, which may not capture the nuances of language or the specific context required for a correct answer. The need for automated or semi-automated validation methods is crucial to ensure the quality of the dataset and, consequently, the performance of the QnA system. The post effectively frames the problem and seeks community input for potential solutions.

Key Takeaways

•Validating QnA datasets is crucial for system performance.
•Cosine similarity alone is insufficient for accurate answer matching.
•Automated or semi-automated validation methods are needed for large datasets.

Reference

“This approach gives me a lot of false negative sentences. Since the dataset is huge, manual checking isn't feasible.”

r/MachineLearning

Analysis

This article highlights the resurgence of pre-transformer NLP techniques in addressing limitations of large language models (LLMs). It argues that methods like Hidden Markov Models (HMMs), Viterbi algorithm, and n-gram smoothing, once considered obsolete, are now being revisited to solve problems where LLMs fall short, particularly in areas like constrained decoding, state compression, and handling linguistic variation. The author draws parallels between modern techniques like Mamba/S4 and continuous HMMs, and between model merging and n-gram smoothing. The article emphasizes the importance of understanding these older methods for tackling the "jagged intelligence" problem of LLMs, where they excel in some areas but fail unpredictably in others.

Key Takeaways

•Pre-transformer NLP techniques are making a comeback.
•LLMs have limitations that older methods can address.
•Understanding classic NLP is crucial for improving LLM performance.
