PARIS: Personalized Activity Recommendation for Improving Sleep Quality

arXiv.org Artificial Intelligence

The quality of sleep has a deep impact on people's physical and mental health. People with insufficient sleep are more likely to report physical and mental distress, activity limitation, anxiety, and pain. Moreover, in the past few years, there has been an explosion of applications and devices for activity monitoring and health tracking. Signals collected from these wearable devices can be used to study and improve sleep quality. In this paper, we utilize the relationship between physical activity and sleep quality to find ways of assisting people improve their sleep using machine learning techniques. People usually have several behavior modes that their bio-functions can be divided into. Performing time series clustering on activity data, we find cluster centers that would correlate to the most evident behavior modes for a specific subject. Activity recipes are then generated for good sleep quality for each behavior mode within each cluster. These activity recipes are supplied to an activity recommendation engine for suggesting a mix of relaxed to intense activities to subjects during their daily routines. The recommendations are further personalized based on the subjects' lifestyle constraints, i.e. their age, gender, body mass index (BMI), resting heart rate, etc, with the objective of the recommendation being the improvement of that night's quality of sleep. This would in turn serve a longer-term health objective, like lowering heart rate, improving the overall quality of sleep, etc.


Nonparametric Matrix Estimation with One-Sided Covariates

arXiv.org Machine Learning

Consider the task of matrix estimation in which a dataset $X \in \mathbb{R}^{n\times m}$ is observed with sparsity $p$, and we would like to estimate $\mathbb{E}[X]$, where $\mathbb{E}[X_{ui}] = f(\alpha_u, \beta_i)$ for some Holder smooth function $f$. We consider the setting where the row covariates $\alpha$ are unobserved yet the column covariates $\beta$ are observed. We provide an algorithm and accompanying analysis which shows that our algorithm improves upon naively estimating each row separately when the number of rows is not too small. Furthermore when the matrix is moderately proportioned, our algorithm achieves the minimax optimal nonparametric rate of an oracle algorithm that knows the row covariates. In simulated experiments we show our algorithm outperforms other baselines in low data regimes.


What Is Edge Computing In AI?

#artificialintelligence

What was the motivation for adding voice and image recognition to the iPhone's SoC? If you've ever used Siri, Apple's voice assistant, you may have run into occasional problems where, instead of responding to your command, she says something along the lines of "Please wait a moment..." This is because at present, Siri uses cloud processing of voice data, and if she is unable to connect to Apple's servers through the internet, that's where the party ends. This is due to change very soon however, as this fall's release of iOS 15 will switch Siri to process your voice commands completely on the device itself. Voice assistants such as Siri, Amazon's Alexa, Google Assistant, or Microsoft's Cortana, on-device processing brings a host of benefits: Reduced latency since the data doesn't have to travel over the internet to be processed with wearable technologies Less use of bandwidth which can translate to cheaper internet bills Better privacy as the processing is all done locally and not on someone else's computer The Natural Language Processing (NLP) functionality on these smart assistants are sometimes designed as a hybrid edge and cloud solution known as "fog computing" because it's at the "edge of the cloud". In these systems, they process some data locally and more complex data in the cloud.

Whether you realize it or not, Artificial Intelligence is everywhere. The application of AI is not only for big sectors or finance or manufacturing, it is also impacting our daily lives. So, let's find out about the applications of AI in your daily life.


Amazon details custom Alexa programs for hospitals and retirement communities

Engadget

Amazon has announced two new programs for Alexa centered around healthcare and retirement homes. Through Alexa Smart Properties, hospitals and senior living communities can run their own custom version of the voice assistant. Retirement homes might tap into Alexa to help residents keep in contact with family and friends, stay in touch with staff, take part in activities and remain engaged with other members of the community. Staff members can use Alexa to broadcast announcements and, of course, the voice assistant can still be used for things like controlling connected devices and smart TVs. Amazon's aim with the healthcare program is to, among other things, let staff members check in with patients without having to enter their rooms. In turn, patients can ask nurses questions, and they'll be able to respond to brief queries without having to leave their station.

How to Measure the Success of a Recommendation System?

#artificialintelligence

Recommender systems are used in a variety of domains, from e-commerce to social media to offer personalized recommendations to customers. The benefit of recommendations for customers, such as reduced information overload, has been a hot topic of research. However, it's unclear how and to what extent recommender systems produce commercial value. It's challenging to create a reliable product suggestion system. However, defining what it means to be reliable is also a challenging task.


Forget dating apps: Here's how the net's newest matchmakers help you find love

MIT Technology Review

Morgan basked in the feel-good vibes of seeing people find each other--"I love love!"--and reveled in the real-life connections she was able to mastermind: multiple dates in her hometown of Portland, Oregon; someone who was thinking of flying to meet somebody in New York because of the thread; even a short relationship. Even today, people continue to add their pictures to the thread, seeking love all across the United States. If this feels a bit like old-fashioned matchmaking, it is. These operations are often ad hoc, based on platforms like Twitter and TikTok, and--unlike the dating apps, with their endless menu of eligible suitors--hyperfocused on one person at a time. Randa Sakallah launched Hot Singles in December 2020 to solve her own dating blues.


DaRE: A Cross-Domain Recommender System with Domain-aware Feature Extraction and Review Encoder

arXiv.org Artificial Intelligence

Recent advent in recommender systems, especially text-aided methods and CDR (Cross-Domain Recommendation) leads to promising results in solving data-sparsity and cold-start problems. Despite such progress, prior algorithms either require user overlapping or ignore domain-aware feature extraction. In addition, text-aided methods exceedingly emphasize aggregated documents and fail to capture the specifics embedded in individual reviews. To overcome such limitations, we propose a novel method, named DaRE (Domainaware Feature Extraction and Review Encoder), a comprehensive solution that consists of three key components; text-based representation learning, domain-aware feature extraction, and a review encoder. DaRE debilitate noises by separating domain-invariant features from domain-specific features through selective adversarial training. DaRE extracts features from aggregated documents, and the review encoder fine-tunes the representations by aligning them with the features extracted from individual reviews. Experiments on four real-world datasets show the superiority of DaRE over state-ofthe-art single-domain and cross-domain methodologies, achieving 9.2 % and 3.6 % improvements, respectively. We upload our implementations (https://anonymous.4open.science/r/DaRE-9CC9/) for a reproducibility
