Minimax Lower Bounds for Transfer Learning with Linear and One-hidden Layer Neural Networks

2 code implementations NeurIPS 2020 Seyed Mohammadreza Mousavi Kalan, Zalan Fabian, A. Salman Avestimehr, Mahdi Soltanolkotabi

In this approach a model trained for a source task, where plenty of labeled training data is available, is used as a starting point for training a model on a related target task with only few labeled training data.

Fitting ReLUs via SGD and Quantized SGD

no code implementations19 Jan 2019 Seyed Mohammadreza Mousavi Kalan, Mahdi Soltanolkotabi, A. Salman Avestimehr

Perhaps unexpectedly, we show that QSGD maintains the fast convergence of SGD to a globally optimal model while significantly reducing the communication cost.

Lagrange Coded Computing: Optimal Design for Resiliency, Security and Privacy

no code implementations4 Jun 2018 Qian Yu, Songze Li, Netanel Raviv, Seyed Mohammadreza Mousavi Kalan, Mahdi Soltanolkotabi, Salman Avestimehr

We consider a scenario involving computations over a massive dataset stored distributedly across multiple workers, which is at the core of distributed learning algorithms.

Polynomially Coded Regression: Optimal Straggler Mitigation via Data Encoding

no code implementations24 May 2018 Songze Li, Seyed Mohammadreza Mousavi Kalan, Qian Yu, Mahdi Soltanolkotabi, A. Salman Avestimehr

In particular, PCR requires a recovery threshold that scales inversely proportionally with the amount of computation/storage available at each worker.

Fundamental Resource Trade-offs for Encoded Distributed Optimization

no code implementations31 Mar 2018 A. Salman Avestimehr, Seyed Mohammadreza Mousavi Kalan, Mahdi Soltanolkotabi

We also analyze the convergence behavior of iterative encoded optimization algorithms, allowing us to characterize fundamental trade-offs between convergence rate, size of data set, accuracy, computational load (or data redundancy), and straggler toleration in this framework.
