Fixed Point Quantization of Deep Convolutional Networks
TLDR
This paper proposes a quantizer design for fixed point implementation of DCNs, formulate and solve an optimization problem to identify optimal fixed point bit-width allocation across DCN layers, and demonstrates that fine-tuning can further enhance the accuracy of fixed point DCNs beyond that of the original floating point model.

Gaussian Interference Networks: Sum Capacity in the Low-Interference Regime and New Outer Bounds on the Capacity Region
TLDR
New, improved outer bounds on the capacity region are developed and it is shown that treating interference as noise achieves the sum capacity of the two-user Gaussian interference channel in a low-interference regime, where the interference parameters are below certain thresholds. Expand
Gaussian interference networks: sum capacity in the low-interference regime and new outer bounds on the capacity region
TLDR
New, improved outer bounds on the capacity region are developed and it is shown that treating interference as noise achieves the sum capacity of the two-user Gaussian interference channel in a low-interference regime, where the interference parameters are below certain thresholds. Expand
Degrees of Freedom of Interference Channels With CoMP Transmission and Reception
TLDR
The key idea is that the zero forcing of the interference corresponding to the formulatype="inline" can be viewed as a shared responsibility between the decoder and the receivers of the message, and the DoF for all is proposed. Expand
Sum capacity of the Gaussian interference channel in the low interference regime
TLDR
Using new upper bounds on the sum capacity of the two-user Gaussian interference channel, it is shown that treating interference as noise achieves the sumcapacity if the interference levels are below certain thresholds. Expand
Sum Capacity of MIMO Interference Channels in the Low Interference Regime
TLDR
It is shown that the low interfered regime can be quite significant for MIMO interference channels, with the low interference threshold being at least as large as the sine of the angle between the direct and cross channel gain vectors for the MISO and SIMO cases. Expand
Degrees of freedom of the K-user interference channel with transmitter cooperation
We consider the K-user Gaussian interference channel in the context of the downlink of a cellular system where the base stations can exchange messages through a backhaul network, and the interferingExpand
Outage probability of multiple-input single-output (MISO) systems with delayed feedback
TLDR
Results show that the loss in performance due to imperfection in CSIR is not significant, if the training power is chosen appropriately, and that BF-IC is better for low SNR and USPA is better at high SNR. Expand
Interference Channels With Coordinated Multipoint Transmission: Degrees of Freedom, Message Assignment, and Fractional Reuse
TLDR
The capacity gain achieved through CoMP transmission is studied in various models of wireless networks that have practical significance and the capacity gain is analyzed through the degrees of freedom (DoF) criterion. Expand
Degrees of freedom (DoF) of locally connected interference channels with coordinated multi-point (CoMP) transmission
TLDR
The relaxation of the cooperation constraint, while maintaining the same load imposed on a backhaul link needed to distribute the messages, results in a gain in the DoF and the asymptotic limit of the per user DoF under the cooperation order constraint is 2M/2M+1. Expand
