  • Distributed source coding using syndromes (DISCUS): design and construction (899 citations)
  • Rate-distortion methods for image and video compression (768 citations)

What are the main themes of his work throughout his whole career to date?

Kannan Ramchandran mainly focuses on Algorithm, Theoretical computer science, Artificial intelligence, Computer network and Decoding methods. The study incorporates disciplines such as Mathematical optimization, Communication channel and Signal processing in addition to Algorithm. His Theoretical computer science research includes themes of Block code and Variable-length code, Distributed source coding.

His research in Artificial intelligence intersects with topics in Computer vision and Pattern recognition. His studies link Distributed computing with Computer network. His work deals with themes such as Reliability, Code, Node, Bandwidth and Erasure code, which intersect with Distributed data store.

He most often published in these fields:

  • Algorithm (25.38%)
  • Theoretical computer science (15.50%)
  • Artificial intelligence (15.16%)

What were the highlights of his more recent work (between 2015-2021)?

  • Algorithm (25.38%)
  • Theoretical computer science (15.50%)
  • Upper and lower bounds (4.94%)

In recent papers he was focusing on the following fields of study:

His main research concerns Algorithm, Theoretical computer science, Upper and lower bounds, Combinatorics and Decoding methods. His work carried out in the field of Algorithm brings together such families of science as Function, Rate of convergence and Truncated mean. His study looks at the relationship between Theoretical computer science and topics such as Speedup, which overlap with Quantization, Heuristics and Stochastic gradient descent.

The various areas that he examines in his Decoding methods study include Distributed computing and Matrix multiplication. His studies in Distributed computing integrate themes in fields like Control, Information sensitivity and Differential privacy. While the research belongs to areas of Latency, he spends his time largely on the problem of Load balancing, intersecting his research to questions surrounding Erasure code.

Between 2015 and 2021, his most popular works were:

  • Speeding Up Distributed Machine Learning Using Codes (438 citations)
  • Byzantine-Robust Distributed Learning: Towards Optimal Statistical Rates (170 citations)
  • High-dimensional coded matrix multiplication (153 citations)

In his most recent research, the most cited papers focused on:

  • Computer network
  • Statistics
  • Artificial intelligence

His primary scientific interests are in Theoretical computer science, Upper and lower bounds, Algorithm, Matrix multiplication and Erasure code. His Theoretical computer science study incorporates themes from Generalization, Rademacher complexity, Norm, Nonlinear system and Key. His research in Algorithm is mostly concerned with Iterative filtering.

Kannan Ramchandran regularly ties together related areas like Computer network in his Erasure code studies. As part of the same scientific family, he usually focuses on Computer network, concentrating on Computer data storage and intersecting with Queueing theory. He works mostly in the field of Robustness, limiting it down to concerns involving Randomness and, occasionally, Artificial intelligence and Machine learning.
