| Để tăng tốc quá trình lấy mẫu, chúng tôi giới thiệu các mô hình xác suất ẩn khử nhiễu (DDIM), một lớp mô hình xác suất ẩn lặp hiệu quả hơn | |
| với cùng quy trình huấn luyện như DDPM. Trong DDPM, quá trình sinh được định nghĩa là quá trình ngược của một quá trình khuếch tán Markov. | |
| Chúng tôi xây dựng một lớp các quá trình khuếch tán phi Markov dẫn đến cùng mục tiêu huấn luyện, nhưng quá trình ngược của chúng có thể lấy mẫu nhanh hơn nhiều. | |
| Chúng tôi chứng minh thực nghiệm rằng DDIM có thể tạo ra các mẫu chất lượng cao nhanh hơn 10 lần đến 50 lần về thời gian thực so với DDPM, cho phép đánh đổi giữa tính toán và chất lượng mẫu, và có thể thực hiện nội suy ảnh có ý nghĩa ngữ nghĩa trực tiếp trong không gian ẩn.</em></p> <p>Mã nguồn gốc của bài báo này có thể được tìm thấy tại <a href="https://github.com/ermongroup/ddim" rel="nofollow">ermongroup/ddim</a>, và bạn có thể liên hệ với tác giả qua <a href="https://tsong.me/" rel="nofollow">tsong.me</a>.</p> <!--[1--><h2 class="relative group"><a id="tips" class="header-link block pr-1.5 text-lg no-hover:hidden with-hover:absolute with-hover:p-1.5 with-hover:opacity-0 with-hover:group-hover:opacity-100 with-hover:right-full" href="#tips"><span><svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" aria-hidden="true" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 256 256"><path d="M167.594 88.393a8.001 8.001 0 0 1 0 11.314l-67.882 67.882a8 8 0 1 1-11.314-11.315l67.882-67.881a8.003 8.003 0 0 1 11.314 0zm-28.287 84.86l-28.284 28.284a40 40 0 0 1-56.567-56.567l28.284-28.284a8 8 0 0 0-11.315-11.315l-28.284 28.284a56 56 0 0 0 79.196 79.197l28.285-28.285a8 8 0 1 0-11.315-11.314zM212.852 43.14a56.002 56.002 0 0 0-79.196 0l-28.284 28.284a8 8 0 1 0 11.314 11.314l28.284-28.284a40 40 0 0 1 56.568 56.567l-28.285 28.285a8 8 0 0 0 11.315 11.314l28.284-28.284a56.065 56.065 0 0 0 0-79.196z" fill="currentColor"></path></svg><!----></span></a> <span><!---->Mẹo<!----></span></h2><!--]--><!----> <p>Bài báo <a href="https://huggingface.co/papers/2305.08891" rel="nofollow">Common Diffusion Noise Schedules and Sample Steps are Flawed</a> cho rằng sự không khớp giữa các cài đặt huấn luyện và suy luận dẫn đến kết quả sinh suy luận không tối ưu cho Stable Diffusion.
