تمثيل الموقف أمر حاسم لبناء الممثلين على علم الموضع في المحولات.تعاني تمثيلات الموقف الموجودة من عدم وجود تعميم لاختبار البيانات بأطوال غير مرئية أو تكلفة حسابية عالية.نحقق التحقيق في تضمين الموقف المطلق (الشكل) لمعالجة كلا المشكلين.الفكرة الأساسية للشكل هي تحقيق التحول الثابتة، وهي ملكية رئيسية لتمثيلات الموقف الناجحة الأخيرة، من خلال تحويل المواقع المطلقة بشكل عشوائي أثناء التدريب.نوضح هذا الشكل مقارنة تجريبيا نظيره أثناء وجوده أبسط وأسرع.
Position representation is crucial for building position-aware representations in Transformers. Existing position representations suffer from a lack of generalization to test data with unseen lengths or high computational cost. We investigate shifted absolute position embedding (SHAPE) to address both issues. The basic idea of SHAPE is to achieve shift invariance, which is a key property of recent successful position representations, by randomly shifting absolute positions during training. We demonstrate that SHAPE is empirically comparable to its counterpart while being simpler and faster.

Text variational autoencoders (VAEs) are notorious for posterior collapse, a phenomenon where the model's decoder learns to ignore signals from the encoder. Because posterior collapse is known to be exacerbated by expressive decoders, Transformers ha
Machine translation has seen rapid progress with the advent of Transformer-based models. These models have no explicit linguistic structure built into them, yet they may still implicitly learn structured relationships by attending to relevant tokens.

Incremental processing allows interactive systems to respond based on partial inputs, which is a desirable property e.g. in dialogue agents. The currently popular Transformer architecture inherently processes sequences as a whole, abstracting away th
Transformer models are expensive to fine-tune, slow for inference, and have large storage requirements. Recent approaches tackle these shortcomings by training smaller models, dynamically reducing the model size, and by training light-weight adapters
