Understanding and Mitigating Hallucinations in Large Language Models

Hallucinations in large language models refer to the generation of content that is not factual, consistent, or grounded in provided context or world knowledge. This phenomenon is often categorized into two types: context hallucinations, where outputs conflict with source material, and extrinsic hallucinations, where outputs are fabricated witho ...

Fine-Tuning ResNet for Hotdog Image Classification Using Transfer Learning

Steps Below we introduce fine‑tuning, a common technique in transfer learning. As illustrated in the following diagram, fine‑tuning consists of four steps. Pre‑train a neural network model (the source model) on a source dataset, e.g., ImageNet. Create a new neural network (the target model). It replicates all model design and parameters from t ...

Text Generation: Unifying Natural Language Tasks as Output Sequences

Modern natural language processing (NLP) increasingly treats diverse tasks as sequence-to-sequence generation problems. Rather than restricting models to classification or extraction, we can frame nearly any NLP task—summarization, correction, translation—as generating a target text from an input text. This paradigm shift enables more flexible ...
