From Gene Expression to Drug Response: A Collaborative Filtering Approach
Cheng Qian, Nicholas D. Sidiropoulos, Magda Amiridi +1
Predicting the response of cancer cells to drugs is an important problem in pharmacogenomics. Recent efforts in generation of large scale datasets profiling gene expression and dru…
Coupled Graphs and Tensor Factorization for Recommender Systems and Community Detection
Vassilis N. Ioannidis, Ahmed S. Zamzam, Georgios B. Giannakis +1
Joint analysis of data from multiple information repositories facilitates uncovering the underlying structure in heterogeneous datasets. Single and coupled matrix-tensor factorizat…
Tensor-Based Parameter Estimation of Double Directional Massive MIMO Channel with Dual-Polarized Antennas
Cheng Qian, Xiao Fu, Nicholas D. Sidiropoulos +1
The 3GPP suggests to combine dual polarized (DP) antenna arrays with the double directional (DD) channel model for downlink channel estimation. This combination strikes a good bala…
Mirror-Prox SCA Algorithm for Multicast Beamforming and Antenna Selection
Mohamed S. Ibrahim, Aritra Konar, Mingyi Hong +1
This paper considers the (NP-)hard problem of joint multicast beamforming and antenna selection. Prior work has focused on using Semi-Definite relaxation (SDR) techniques in an att…
Learning Hidden Markov Models from Pairwise Co-occurrences with Application to Topic Modeling
Kejun Huang, Xiao Fu, Nicholas D. Sidiropoulos
We present a new algorithm for identifying the transition and emission probabilities of a hidden Markov model (HMM) from the emitted data. Expectation-maximization becomes computat…
