A Survey of Classical And Quantum Sequence Models

1 code implementation15 Dec 2023 I-Chi Chen, Harshdeep Singh, V L Anukruti, Brian Quanz, Kavitha Yogaraj

Our primary objective is to conduct a brief survey of various classical and quantum neural net sequence models, which includes self-attention and recurrent neural networks, with a focus on recent quantum approaches proposed to work with near-term quantum devices, while exploring some basic enhancements for these quantum models.

An Optimistic-Robust Approach for Dynamic Positioning of Omnichannel Inventories

no code implementations17 Oct 2023 Pavithra Harsha, Shivaram Subramanian, Ali Koc, Mahesh Ramakrishna, Brian Quanz, Dhruv Shah, Chandra Narayanaswami

Using a real-world dataset from a large American omnichannel retail chain, a business value assessment during a peak period indicates over a 15% profitability gain for BIO over RO and other baselines while also preserving the (practical) worst case performance.

Hierarchical Proxy Modeling for Improved HPO in Time Series Forecasting

no code implementations28 Nov 2022 Arindam Jati, Vijay Ekambaram, Shaonli Pal, Brian Quanz, Wesley M. Gifford, Pavithra Harsha, Stuart Siegel, Sumanta Mukherjee, Chandra Narayanaswami

To address this test-validation mismatch, we propose a novel technique, H-Pro to drive HPO via test proxies by exploiting data hierarchies often associated with time series datasets.

Towards Creativity Characterization of Generative Models via Group-based Subset Scanning

no code implementations1 Mar 2022 Celia Cintas, Payel Das, Brian Quanz, Girmaw Abebe Tadesse, Skyler Speakman, Pin-Yu Chen

We propose group-based subset scanning to identify, quantify, and characterize creative processes by detecting a subset of anomalous node-activations in the hidden layers of the generative models.

Deep Policy Iteration with Integer Programming for Inventory Management

no code implementations4 Dec 2021 Pavithra Harsha, Ashish Jagmohan, Jayant R. Kalagnanam, Brian Quanz, Divya Singhvi

Finally, to make RL algorithms more accessible for inventory management researchers, we also discuss a modular Python library developed that can be used to test the performance of RL algorithms with various supply chain structures.

Learning to shortcut and shortlist order fulfillment deciding

no code implementations4 Oct 2021 Brian Quanz, Ajay Deshpande, Dahai Xing, Xuan Liu

Essentially, those assignments that can be predicted with high confidence can be used to shortcut, or bypass, the expensive deciding process, or else a set of most likely assignments can be used for shortlisting -- sending a much smaller set of candidates for consideration by the fulfillment deciding system.

Predicting Deep Neural Network Generalization with Perturbation Response Curves

no code implementations NeurIPS 2021 Yair Schiff, Brian Quanz, Payel Das, Pin-Yu Chen

However, despite these successes, the recent Predicting Generalization in Deep Learning (PGDL) NeurIPS 2020 competition suggests that there is a need for more robust and efficient measures of network generalization.

Gi and Pal Scores: Deep Neural Network Generalization Statistics

no code implementations8 Apr 2021 Yair Schiff, Brian Quanz, Payel Das, Pin-Yu Chen

The field of Deep Learning is rich with empirical evidence of human-like performance on a variety of regression, classification, and control tasks.

Towards creativity characterization of generative models via group-based subset scanning

no code implementations1 Apr 2021 Celia Cintas, Payel Das, Brian Quanz, Skyler Speakman, Victor Akinwande, Pin-Yu Chen

We propose group-based subset scanning to quantify, detect, and characterize creative processes by detecting a subset of anomalous node-activations in the hidden layers of generative models.

Temporal Latent Auto-Encoder: A Method for Probabilistic Multivariate Time Series Forecasting

no code implementations25 Jan 2021 Nam Nguyen, Brian Quanz

Probabilistic forecasting of high dimensional multivariate time series is a notoriously challenging task, both in terms of computational burden and distribution modeling.

Practical application improvement to Quantum SVM: theory to practice

no code implementations14 Dec 2020 Jae-Eun Park, Brian Quanz, Steve Wood, Heather Higgins, Ray Harishankar

For the quantum SVM under NISQ, we use quantum feature maps to translate data into quantum states and build the SVM kernel out of these quantum states, and further compare with classical SVM with radial basis function (RBF) kernels.

Machine learning based co-creative design framework

no code implementations23 Jan 2020 Brian Quanz, Wei Sun, Ajay Deshpande, Dhruv Shah, Jae-Eun Park

We propose a flexible, co-creative framework bringing together multiple machine learning techniques to assist human users to efficiently produce effective creative designs.

Toward A Neuro-inspired Creative Decoder

no code implementations6 Feb 2019 Payel Das, Brian Quanz, Pin-Yu Chen, Jae-wook Ahn, Dhruv Shah

Creativity, a process that generates novel and meaningful ideas, involves increased association between task-positive (control) and task-negative (default) networks in the human brain.
