Real-Time Decentralized knowledge Transfer at the Edge

1 code implementation11 Nov 2020 Orpaz Goldstein, Mohammad Kachuee, Derek Shiell, Majid Sarrafzadeh

Transferring knowledge in a selective decentralized approach enables models to retain their local insights, allowing for local flavors of a machine learning model.

Cost-Sensitive Feature-Value Acquisition Using Feature Relevance

no code implementations17 Dec 2019 Kimmo Kärkkäinen, Mohammad Kachuee, Orpaz Goldstein, Majid Sarrafzadeh

The chosen features should increase the prediction accuracy for a low cost, but determining which features will do that is challenging.

Target-Focused Feature Selection Using a Bayesian Approach

no code implementations15 Sep 2019 Orpaz Goldstein, Mohammad Kachuee, Kimmo Karkkainen, Majid Sarrafzadeh

In many real-world scenarios where data is high dimensional, test time acquisition of features is a non-trivial task due to costs associated with feature acquisition and evaluating feature value.

Generative Imputation and Stochastic Prediction

2 code implementations22 May 2019 Mohammad Kachuee, Kimmo Karkkainen, Orpaz Goldstein, Sajad Darabi, Majid Sarrafzadeh

In order to make imputations, we train a simple and effective generator network to generate imputations that a discriminator network is tasked to distinguish.

Cost-Sensitive Diagnosis and Learning Leveraging Public Health Data

2 code implementations19 Feb 2019 Mohammad Kachuee, Kimmo Karkkainen, Orpaz Goldstein, Davina Zamanzadeh, Majid Sarrafzadeh

Furthermore, based on the suggested dataset, we provide a comparison of recent and state-of-the-art approaches to cost-sensitive feature acquisition and learning.
