Iterative Answer Prediction With Pointer-Augmented Multimodal Transformers for TextVQA [PDF]

open access: yesComputer Vision and Pattern Recognition, 2019
Many visual scenes contain text that carries crucial information, and it is thus essential to understand text in images for downstream reasoning tasks. For example, a deep water label on a warning sign warns people about the danger in the scene.

Hadamard–Viterbi Joint Soft Decoding for MFSK Underwater Acoustic Communications

open access: yesRemote Sensing, 2022
Multiple Frequency-Shift Keying (MFSK) has been used widely for underwater acoustic communications due to its low complexity and channel robustness.

Generalization Bounds for Neural Belief Propagation Decoders [PDF]

open access: yes, 2023
Machine learning based approaches are being increasingly used for designing decoders for next generation communication systems. One widely used framework is neural belief propagation (NBP), which unfolds the belief propagation (BP) iterations into a deep neural network and the parameters are trained in a data-driven manner. NBP decoders have been shown

From maximum likelihood to iterative decoding [PDF]

open access: yes2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
Iterative decoding is considered in this paper from an optimization point of view. Starting from the optimal maximum likelihood decoding, a (tractable) approximate criterion is derived. The global maximum of the approximate criterion is analyzed: the maximum likelihood solution can be retrieved from the approximate criterion in some particular cases ...

Mask-Predict: Parallel Decoding of Conditional Masked Language Models

open access: yesConference on Empirical Methods in Natural Language Processing, 2019
Most machine translation systems generate text autoregressively from left to right. We, instead, use a masked language modeling objective to train a model to predict any subset of the target words, conditioned on both the input text and a partially ...

Iterative Multiuser Detection and Decoding with Spatially Coupled Interleaving [PDF]

open access: yes, 2013
Spatially coupled (SC) interleaving is proposed to improve the performance of iterative multiuser detection and decoding (MUDD) for quasi-static fading multiple-input multiple-output systems.

A Novel Iterative Soft-Decision Decoding Algorithm for RS-SPC Product Codes [PDF]

open access: yesarXiv, 2021
This paper presents a generalized construction of RS-SPC product codes. A low-complexity joint-decoding scheme is proposed for these codes, in which a BP-based iterative decoding is performed based on the binary expansion of the whole parity-check matrix. Various powerful RS codes can be used as the component codes for RS-SPC product codes, which gives

Approximate MIMO Iterative Processing with Adjustable Complexity Requirements [PDF]

open access: yes, 2011
Targeting always the best achievable bit error rate (BER) performance in iterative receivers operating over multiple-input multiple-output (MIMO) channels may result in significant waste of resources, especially when the achievable BER is orders of ...

Low-Complexity CRC Aided Joint Iterative Detection and SCL Decoding Receiver of Polar Coded SCMA System

open access: yesIEEE Access, 2020
As the fifth-generation (5G) wireless networks' key technology, the joint design of SCMA and polar code is concerned by the future communication system. In this paper, a CRC aided joint iterative detection and successive cancellation list (SCL) decoding (

Modified belief propagation decoders for quantum low-density parity-check codes [PDF]

open access: yesPhys. Rev. A 100, 012330 (2019), 2019
Quantum low-density parity-check codes can be decoded using a syndrome based $\mathrm{GF}(4)$ belief propagation decoder. However, the performance of this decoder is limited both by unavoidable $4$-cycles in the code's factor graph and the degenerate nature of quantum errors.
