OrcoDCS: An IoT-Edge Orchestrated Online Deep Compressed Sensing Framework

no code implementations5 Aug 2023 Cheng-Wei Ching, Chirag Gupta, Zi Huang, Liting Hu

However, the existing compressed data aggregation (CDA) frameworks (e. g., compressed sensing-based data aggregation, deep learning(DL)-based data aggregation) do not possess the flexibility and adaptivity required to handle distinct sensing tasks and environmental changes.

Parity Calibration

1 code implementation29 May 2023 Youngseog Chung, Aaron Rumack, Chirag Gupta

In a sequential regression setting, a decision-maker may be primarily concerned with whether the future observation will increase or decrease compared to the current one, rather than the actual value of the future observation.

Online Platt Scaling with Calibeating

no code implementations28 Apr 2023 Chirag Gupta, Aaditya Ramdas

We present an online post-hoc calibration method, called Online Platt Scaling (OPS), which combines the Platt scaling technique with online logistic regression.

Faster online calibration without randomization: interval forecasts and the power of two choices

no code implementations27 Apr 2022 Chirag Gupta, Aaditya Ramdas

We study the problem of making calibrated probabilistic forecasts for a binary sequence generated by an adversarial nature.

Distribution-free calibration guarantees for histogram binning without sample splitting

1 code implementation10 May 2021 Chirag Gupta, Aaditya K. Ramdas

We prove calibration guarantees for the popular histogram binning (also called uniform-mass binning) method of Zadrozny and Elkan [2001].

Modern Machine and Deep Learning Systems as a way to achieve Man-Computer Symbiosis

no code implementations24 Jan 2021 Chirag Gupta

Man-Computer Symbiosis (MCS) was originally envisioned by the famous computer pioneer J. C. R.

Distribution-free binary classification: prediction sets, confidence intervals and calibration

1 code implementation NeurIPS 2020 Chirag Gupta, Aleksandr Podkopaev, Aaditya Ramdas

We study three notions of uncertainty quantification -- calibration, confidence intervals and prediction sets -- for binary classification in the distribution-free setting, that is without making any distributional assumptions on the data.

Shallow Encoder Deep Decoder (SEDD) Networks for Image Encryption and Decryption

no code implementations9 Jan 2020 Chirag Gupta

This paper explores a new framework for lossy image encryption and decryption using a simple shallow encoder neural network E for encryption, and a complex deep decoder neural network D for decryption.

Cryptanalysis

Self learning robot using real-time neural networks

no code implementations6 Jan 2020 Chirag Gupta, Chikita Nangia, Chetan Kumar

With the advancements in high volume, low precision computational technology and applied research on cognitive artificially intelligent heuristic systems, machine learning solutions through neural networks with real-time learning has seen an immense interest in the research community as well the industry.

Self-Learning

Nested conformal prediction and quantile out-of-bag ensemble methods

1 code implementation23 Oct 2019 Chirag Gupta, Arun K. Kuchibhotla, Aaditya K. Ramdas

Conformal prediction is a popular tool for providing valid prediction sets for classification and regression problems, without relying on any distributional assumptions on the data.

Path Length Bounds for Gradient Descent and Flow

no code implementations2 Aug 2019 Chirag Gupta, Sivaraman Balakrishnan, Aaditya Ramdas

We derive bounds on the path length $\zeta$ of gradient descent (GD) and gradient flow (GF) curves for various classes of smooth convex and nonconvex functions.

Support Recovery for Orthogonal Matching Pursuit: Upper and Lower bounds

no code implementations NeurIPS 2018 Raghav Somani, Chirag Gupta, Prateek Jain, Praneeth Netrapalli

This paper studies the problem of sparse regression where the goal is to learn a sparse vector that best optimizes a given objective function.
