Starting from the generalized exponential function expκ(x)=(1+κ2x2+κx)1/κ, with exp0(x)=exp(x), proposed in Ref. [G. Kaniadakis, Physica A \textbf{296}, 405 (2001)], the survival function P>(x)=expκ(−βxα), where x∈R+, α,β>0, and κ∈[0,1), is considered in order to…
With the increasing demand for large amount of labeled data, crowdsourcing has been used in many large-scale data mining applications. However, most existing works in crowdsourcing mainly focus on label inference and incentive design. In this paper, we address a different problem of adaptive crowd teaching, which is a …
Spaced repetition is among the most studied learning strategies in the cognitive science literature. It consists in temporally distributing exposure to an information so as to improve long-term memorization. Providing students with an adaptive and personalized distributed practice schedule would benefit more than just …
Federated learning is a distributed, on-device computation framework that enables training global models without exporting sensitive user data to servers. In this work, we describe methods to extend the federation framework to evaluate strategies for personalization of global models. We present tools to analyze the eff…
The Myers-Briggs Type Indicator (MBTI) is a popular personality metric that uses four dichotomies as indicators of personality traits. This paper examines the use of pre-trained language models to predict MBTI personality types based on scraped labeled texts. The proposed model reaches an accuracy of 0.47 for correct…
Explanation in machine learning and related fields such as artificial intelligence aims at making machine learning models and their decisions understandable to humans. Existing work suggests that personalizing explanations might help to improve understandability. In this work, we derive a conceptualization of personali…
We discuss training techniques, objectives and metrics toward personalization of deep learning models. In machine learning, personalization addresses the goal of a trained model to target a particular individual by optimizing one or more performance metrics, while conforming to certain constraints. To personalize, we i…
Paper proposes FedPer to combat statistical heterogeneity in federated learning for personalized tasks.
problem Statistical heterogeneity in federated learning data degrades performance of traditional federated averaging.
method FedPer: a base + personalization layer approach for federated training of deep feedforward neural networks.
result FedPer effectively combats statistical heterogeneity in non-identical data partitions of CIFAR datasets and personalized image aesthetics datasets.
A long user history inevitably reflects the transitions of personal interests over time. The analyses on the user history require the robust sequential model to anticipate the transitions and the decays of user interests. The user history is often modeled by various RNN structures, but the RNN structures in the recomme…
The paper tackles carousel personalization in music streaming apps using contextual bandits.
problem Selecting relevant items to display in carousels for personalized content recommendation.
method Modeling carousel personalization as a contextual multi-armed bandit problem with multiple plays, cascade-based updates and delayed batch feedback.
result Empirically shows the effectiveness of the framework in capturing characteristics of real-world carousels.
This paper improves federated learning by selecting between global and personalized models based on uncertainty.
problem Inherent heterogeneity and diverse data distributions in federated learning.
method Introduces a new approach to federated learning that models predictive uncertainties to select between global and personalized models.
result The model performs better on out-of-distribution data and on par with state-of-the-art personalized federated learning algorithms in standard scenarios.
Object tracking is an ubiquitous problem that appears in many applications such as remote sensing, audio processing, computer vision, human-machine interfaces, human-robot interaction, etc. Although thoroughly investigated in computer vision, tracking a time-varying number of persons remains a challenging open problem.…
Wi-Fi signals-based person identification attracts increasing attention in the booming Internet-of-Things era mainly due to its pervasiveness and passiveness. Most previous work applies gaits extracted from WiFi distortions caused by the person walking to achieve the identification. However, to extract useful gait, a p…
