SPEEDNet: Salient Pyramidal Enhancement Encoder-Decoder Network for Colonoscopy Images

no code implementations2 Dec 2023 Tushir Sahu, Vidhi Bhatt, Sai Chandra Teja R, Sparsh Mittal, Nagesh Kumar S

A DIPC block combines the dilated involution layers pairwise into a pyramidal structure to convert the feature maps into a compact space.

Rethinking Intermediate Layers design in Knowledge Distillation for Kidney and Liver Tumor Segmentation

no code implementations28 Nov 2023 Vandan Gorade, Sparsh Mittal, Debesh Jha, Ulas Bagci

HLFD strategically distills knowledge from a combination of middle layers to earlier layers and transfers final layer knowledge to intermediate layers at both the feature and pixel levels.

Modeling Data Reuse in Deep Neural Networks by Taking Data-Types into Cognizance

no code implementations6 Aug 2020 Nandan Kumar Jha, Sparsh Mittal

arithmetic intensity, does not always correctly estimate the degree of data reuse in DNNs since it gives equal importance to all the data types.

DeepPeep: Exploiting Design Ramifications to Decipher the Architecture of Compact DNNs

no code implementations30 Jul 2020 Nandan Kumar Jha, Sparsh Mittal, Binod Kumar, Govardhan Mattela

The remarkable predictive performance of deep neural networks (DNNs) has led to their adoption in service domains of unprecedented scale and scope.

DRACO: Co-Optimizing Hardware Utilization, and Performance of DNNs on Systolic Accelerator

no code implementations26 Jun 2020 Nandan Kumar Jha, Shreyas Ravishankar, Sparsh Mittal, Arvind Kaushik, Dipan Mandal, Mahesh Chandra

The number of processing elements (PEs) in a fixed-sized systolic accelerator is well matched for large and compute-bound DNNs; whereas, memory-bound DNNs suffer from PE underutilization and fail to achieve peak performance and energy efficiency.

The Ramifications of Making Deep Neural Networks Compact

no code implementations26 Jun 2020 Nandan Kumar Jha, Sparsh Mittal, Govardhan Mattela

Reducing the number of parameters in DNNs increases the number of activations which, in turn, increases the memory footprint.

E2GC: Energy-efficient Group Convolution in Deep Neural Networks

no code implementations26 Jun 2020 Nandan Kumar Jha, Rajat Saini, Subhrajit Nag, Sparsh Mittal

We show that, at comparable computational complexity, DNNs with constant group size (E2GC) are more energy-efficient than DNNs with a fixed number of groups (F$g$GC).
