Local Intrinsic Dimensional Entropy

1 code implementation5 Apr 2023 Rohan Ghosh, Mehul Motani

For a finite $|\mathcal{X}|$, this yields robust entropy measures which satisfy many important properties, such as invariance to bijections, while the same is not true for continuous spaces (where $|\mathcal{X}|=\infty$).

AP: Selective Activation for De-sparsifying Pruned Neural Networks

no code implementations9 Dec 2022 Shiyu Liu, Rohan Ghosh, Dylan Tan, Mehul Motani

However, in network pruning, we find that the sparsity introduced by ReLU, which we quantify by a term called dynamic dead neuron rate (DNR), is not beneficial for the pruned network.

Optimizing Learning Rate Schedules for Iterative Pruning of Deep Neural Networks

no code implementations9 Dec 2022 Shiyu Liu, Rohan Ghosh, John Tan Chong Min, Mehul Motani

(ii) In addition to the strong theoretical motivation, SILO is empirically optimal in the sense of matching an Oracle, which exhaustively searches for the optimal value of max_lr via grid search.

Towards Better Long-range Time Series Forecasting using Generative Forecasting

no code implementations9 Dec 2022 Shiyu Liu, Rohan Ghosh, Mehul Motani

In this paper, we propose a new forecasting strategy called Generative Forecasting (GenF), which generates synthetic data for the next few time steps and then makes long-range forecasts based on generated and observed data.

Achieving Low Complexity Neural Decoders via Iterative Pruning

no code implementations11 Dec 2021 Vikrant Malik, Rohan Ghosh, Mehul Motani

The advancement of deep learning has led to the development of neural decoders for low latency communications.

Network-to-Network Regularization: Enforcing Occam's Razor to Improve Generalization

1 code implementation NeurIPS 2021 Rohan Ghosh, Mehul Motani

Empirical studies find that conventional training of neural networks, unlike network-to-network regularization, leads to networks of high KG and lower test accuracies.

Towards Better Long-range Time Series Forecasting using Generative Adversarial Networks

no code implementations17 Oct 2021 Shiyu Liu, Rohan Ghosh, Mehul Motani

In this paper, we propose a new forecasting strategy called Generative Forecasting (GenF), which generates synthetic data for the next few time steps and then makes long-range forecasts based on generated and observed data.

Co-complexity: An Extended Perspective on Generalization Error

no code implementations1 Jan 2021 Rohan Ghosh, Mehul Motani

Subsequently, we propose a joint entropy-like measure of complexity between function spaces (classifier and generator), called co-complexity, which leads to tighter bounds on the generalization error in this setting.

Investigating Convolutional Neural Networks using Spatial Orderness

no code implementations18 Aug 2019 Rohan Ghosh, Anupam K. Gupta, Mehul Motani

Convolutional Neural Networks (CNN) have been pivotal to the success of many state-of-the-art classification problems, in a wide variety of domains (for e. g. vision, speech, graphs and medical imaging).

Scale Steerable Filters for Locally Scale-Invariant Convolutional Neural Networks

1 code implementation10 Jun 2019 Rohan Ghosh, Anupam K. Gupta

Augmenting transformation knowledge onto a convolutional neural network's weights has often yielded significant improvements in performance.

Spatiotemporal Filtering for Event-Based Action Recognition

no code implementations17 Mar 2019 Rohan Ghosh, Anupam Gupta, Andrei Nakagawa, Alcimar Soares, Nitish Thakor

In this work we introduce spatiotemporal filtering in the spike-event domain, as an alternative way of channeling spatiotemporal information through to a convolutional neural network.

no code implementations16 Mar 2019 Rohan Ghosh, Anupam Gupta, Siyi Tang, Alcimar Soares, Nitish Thakor

Unlike conventional frame-based sensors, event-based visual sensors output information through spikes at a high temporal resolution.
