تعد شيفرات فحص التكافؤ منخفضة الكثافة الالتفافية (LDPC-CC) من شيفرات
تصحيح الخطأ الأمامي و التي تجمع بين قوة شيفرات LDPC البلوكية و الشيفرات
الالتفافية. و تملك هذه الشيفرات عدة ميزات منها إمكانية تشفير البيانات ذات الطول
العشوائي إضافة إلى إمكانية فك تشفيرها من خلال فاك تشفير وحيد.
The Low-Density Parity Check Convolutional Codes (LDPC-CC)
are considered of forward error correction codes, which combine
the power of LDPC block codes and Convolutional codes. LDPCCC
have several features such as they can be encoded with arbitrary
length by simple shift registers and can be decode by only one
decoder.

The process of transfer a speech signal by high confidentially and as quickly as possible through the Internet needs to develop compression and encryption technology for a speech signal, so as, to reduce its size and make it understandable to persons
Narrative generation is an open-ended NLP task in which a model generates a story given a prompt. The task is similar to neural response generation for chatbots; however, innovations in response generation are often not applied to narrative generatio
This paper introduces a new algorithm to solve some problems
that data clustering algorithms such as K-Means suffer from.
This new algorithm by itself is able to cluster data without the
need of other clustering algorithms.
Although grammatical error correction (GEC) has achieved good performance on texts written by learners of English as a second language, performance on low error density domains where texts are written by English speakers of varying levels of proficie
Entity linking is an important problem with many applications. Most previous solutions were designed for settings where annotated training data is available, which is, however, not the case in numerous domains. We propose a light-weight and scalable
