The diminishing state of shared reality on US television news

no code implementations29 Oct 2023 Homa Hosseinmardi, Samuel Wolken, David M. Rothschild, Duncan J. Watts

With regard to consumption, we find more mixed evidence: while broadcast news has indeed declined in popularity, it remains the dominant source of news for roughly 50\% more Americans than does cable; moreover, its decline, while somewhat attributable to cable, appears driven more by a shift away from news consumption altogether than a growth in cable consumption.

Examining the consumption of radical content on YouTube

no code implementations25 Nov 2020 Homa Hosseinmardi, Amir Ghasemian, Aaron Clauset, Markus Mobius, David M. Rothschild, Duncan J. Watts

Although it is under-studied relative to other social media platforms, YouTube is arguably the largest and most engaging online media consumption platform in the world.

Learning Behavioral Representations from Wearable Sensors

no code implementations16 Nov 2019 Nazgol Tavabi, Homa Hosseinmardi, Jennifer L. Villatte, Andrés Abeliuk, Shrikanth Narayanan, Emilio Ferrara, Kristina Lerman

Continuous collection of physiological data from wearable sensors enables temporal characterization of individual behaviors.

Stacking Models for Nearly Optimal Link Prediction in Complex Networks

2 code implementations17 Sep 2019 Amir Ghasemian, Homa Hosseinmardi, Aram Galstyan, Edoardo M. Airoldi, Aaron Clauset

These results indicate that the state-of-the-art for link prediction comes from combining individual algorithms, which achieves nearly optimal predictions.

Discovering Hidden Structure in High Dimensional Human Behavioral Data via Tensor Factorization

no code implementations21 May 2019 Homa Hosseinmardi, Hsien-Te Kao, Kristina Lerman, Emilio Ferrara

In recent years, the rapid growth in technology has increased the opportunity for longitudinal human behavioral studies.

Tensor Embedding: A Supervised Framework for Human Behavioral Data Mining and Prediction

no code implementations31 Aug 2018 Homa Hosseinmardi, Amir Ghasemian, Shrikanth Narayanan, Kristina Lerman, Emilio Ferrara

Today's densely instrumented world offers tremendous opportunities for continuous acquisition and analysis of multimodal sensor data providing temporal characterization of an individual's behaviors.

Capturing Edge Attributes via Network Embedding

1 code implementation8 May 2018 Palash Goyal, Homa Hosseinmardi, Emilio Ferrara, Aram Galstyan

Here we propose a novel embedding method that uses both network structure and edge attributes to learn better network representations.

Evaluating Overfit and Underfit in Models of Network Community Structure

1 code implementation28 Feb 2018 Amir Ghasemian, Homa Hosseinmardi, Aaron Clauset

These results introduce both a theoretically principled approach to evaluate over and underfitting in models of network community structure and a realistic benchmark by which new methods may be evaluated and compared.
