Unbiased Sentence Encoder For Large-Scale Multi-lingual Search Engines
Mahdi Hajiaghayi, Monir Hajiaghayi, Mark Bolin
In this paper, we present a multi-lingual sentence encoder that can be used in search engines as a query and document encoder. This embedding enables a semantic similarity score be…
Code Failure Prediction and Pattern Extraction using LSTM Networks
Mahdi Hajiaghayi, Ehsan Vahedi
In this paper, we use a well-known Deep Learning technique called Long Short Term Memory (LSTM) recurrent neural networks to find sessions that are prone to code failure in applica…
MDS Codes with Progressive Engagement Property for Cloud Storage Systems
Mahdi Hajiaghayi, Hamid Jafarkhani
Fast and efficient failure recovery is a new challenge for cloud storage systems with a large number of storage nodes. A pivotal recovery metric upon the failure of a storage node…
Jointly Optimal Channel and Power Assignment for Dual-Hop Multi-channel Multi-user Relaying
Mahdi Hajiaghayi, Min Dong, Ben Liang
We consider the problem of jointly optimizing channel pairing, channel-user assignment, and power allocation, to maximize the weighted sum-rate, in a single-relay cooperative syste…
Jointly Optimal Channel Pairing and Power Allocation for Multichannel Multihop Relaying
Mahdi Hajiaghayi, Min Dong, Ben Liang
We study the problem of channel pairing and power allocation in a multichannel multihop relay network to enhance the end-to-end data rate. Both amplify-and-forward (AF) and decode-…
Optimal Unitary Linear Processing for Amplify-and-Forward Cooperative OFDM systems
Min Dong, Mahdi Hajiaghayi, Ben Liang
In this paper, we consider the amplified-and-forward relaying in an OFDM system with unitary linear processing at the relay. We proposed a general analytical framework to find the…
