Lightweight Conceptual Dictionary Learning for Text Classification Using Information Compression
We propose a novel, lightweight supervised dictionary learning framework for text classification based on data compression and representation.
Improving Robustness and Accuracy of Ponzi Scheme Detection on Ethereum Using Time-Dependent Features
The contract-code-based approach, while achieving very high accuracy, is not robust: first, the source codes of a majority of contracts on Ethereum are not available, and second, a Ponzi developer can fool a contract-code-based detection model by obfuscating the opcode or inventing a new profit distribution logic that cannot be detected (since these models were trained on existing Ponzi logics only).
Committed Private Information Retrieval
A PIR scheme is $v$-verifiable if the client can verify the correctness of the retrieved $x_i$ even when $v \leq k$ servers collude and try to fool the client by sending manipulated data.
Low-Complexity Linear Diversity-Combining Detector for MIMO-OTFS
In the proposed detector, the copies of the transmitted symbol-vectors received through the different diversity branches (propagation paths and receive antennas) are linearly combined using the maximum ratio combining (MRC) technique to iteratively improve the signal to interference plus noise ratio (SINR) at the output of the combiner.
Unitary-Precoded Single-Carrier Waveforms for High Mobility: Detection and Channel Estimation
This paper presents unitary-precoded single-carrier (USC) modulation as a family of waveforms based on multiplexing the information symbols on time domain unitary basis functions.
Orthogonal Time Sequency Multiplexing Modulation: Analysis and Low-Complexity Receiver Design
This paper proposes orthogonal time sequency multiplexing (OTSM), a novel single carrier modulation scheme that places information symbols in the delay-sequency domain followed by a cascade of time-division multiplexing (TDM) and Walsh-Hadamard sequence multiplexing.
Low Complexity Iterative Rake Decision Feedback Equalizer for Zero-Padded OTFS systems
We further propose a Gauss-Seidel based over-relaxation parameter in the rake detector to improve the performance and the convergence speed of the iterative detection.
PAC Codes: Sequential Decoding vs List Decoding
In the Shannon lecture at the 2019 International Symposium on Information Theory (ISIT), Ar{\i}kan proposed to employ a one-to-one convolutional transform as a pre-coding step before the polar transform.
