Batches Stabilize the Minimum Norm Risk in High Dimensional Overparameterized Linear Regression
Shahar Stein Ioushua, Inbar Hasidim, Ofer Shayevitz +1
Learning algorithms that divide the data into batches are prevalent in many machine-learning applications, typically offering useful trade-offs between computational efficiency and…
On the Number of Graphs with a Given Histogram
Shahar Stein Ioushua, Ofer Shayevitz
Let be a large (simple, unlabeled) dense graph on vertices. Suppose that we only know, or can estimate, the empirical distribution of the number of subgraphs that each…
RF Chain Reduction for MIMO Systems: A Hardware Prototype
Tierui Gong, Nir Shlezinger, Shahar Stein Ioushua +3
Radio frequency (RF) chain circuits play a major role in digital receiver architectures, allowing passband communication signals to be processed in baseband. When operating at high…
Pilot Contamination Mitigation with Reduced RF Chains
Shahar S. Ioushua, Yonina C. Eldar
Massive multiple-input multiple-output (MIMO) communication is a promising technology for increasing spectral efficiency in wireless networks. Two of the main challenges massive MI…
Hybrid Analog-Digital Beamforming for Massive MIMO Systems
Shahar Stein Ioushua, Yonina C. Eldar
In massive MIMO systems, hybrid beamforming is an essential technique for exploiting the potential array gain without using a dedicated RF chain for each antenna. In this work, we…
