We present a complimentary objective for training recurrent neural networks (RNN) with gating units that helps with regularization and interpretability of the trained model. Attention-based RNN models have shown success in many difficult sequence to sequence classification problems with long and short term dependencies, however these models are prone to overfitting. In this paper, we describe h...

The problem of forming validation regions or gates for new sensor mea surements obtained when tracking targets in clutter is considered Target dynamics and measurement characteristics are modeled with possible non Gaussianities or nonlinearities so that some degree of approximation is usually required in the computation of the ltering densities for the target position and predictive densities f...

In this paper we discuss a model of quantum computer in which a state is an operator of density matrix and gates are general quantum operations, not necessarily unitary. A mixed state (operator of density matrix) of n two-level quantum systems is considered as an element of 4n-dimensional operator Hilbert space (Liouville space). It allows to use a quantum computer model with four-valued logic....

In this paper we generalize the usual model of quantum computer to a model in which the state is an operator of density matrix and the gates are general superoperators (quantum operations), not necessarily unitary. A mixed state (operator of density matrix) of n twolevel quantum system (open or closed n-qubit system) is considered as an element of 4dimensional operator Hilbert space (Liouville ...

In this paper, we show realization of macrolevel ternary reversible 2-qudit Feynman gate, 3-qudit controlled Feynman gate, and 3-qudit Toffoli gates using ternary reversible 1-qudit gates and 2-qudit Muthukrishnan-Stroud gates, which are theoretically realizable using quantum technology such as liquid ion trap [10]. Then we show the design of ternary reversible multiplexer and demultiplexer usi...

Mapping a circuit of reversible gates to a circuit of elementary quantum gates is a key step in synthesizing quantum realizations of Boolean functions. The library containing NOT, controlled-NOT and controlled square-root-of-NOT gates has been considered extensively. In this paper, we extend the library to include fourth-root-of-NOT gates. Experimental results using REVLIB benchmark circuits sh...

Quantum-dot cellular automata (QCA) are nanoscale digital logic constructs that use electrons in arrays of quantum dots to carry out binary operations. In this paper, a basic building block for QCA will be proposed. The proposed basic building block can be customized to implement classical gates, such as XOR and XNOR gates, and reversible gates, such as CNOT and Toffoli gates, with less cell co...
