Visualizing Personal Nutrition Intake and Emotions

Duration: One Semesternew
Goals: Using tools like D3 to build an environment to let users explore, interact, and understand what their food journey has been in the past year, and how they are correlated with their emotion and mood.
Responsible TA: Onur Yuruten (onur DOT yuruten AT epfl.ch)
Student Name: Yumeng Hou
Keywords: information visualization, machine learning, sentiment analysis, personal health
Abstract:

Existing apps do not do justice to the amount of attention we pay to personal food and nutrition intake. We spend three times a day to select, prepare, and consume our meals. And if we are able to share with our friends and family members, these meals can contribute to the most memorable moments of our lives. How can we make a digital diary of our food consumption and the emotions that accompanied them? how can we make these memories as delicious as the food we ate? This project aims at exploring both information visualization issues as well as personal health issues. Along the way, we want our students to have fun with the D3 tool and learn a few things about color design. 

The responsible student will:

  • Survey what has been in this field including work from our lab
  • Build the food and mood visualizaiton environment in D3
  • Make it available to the Web users
Related Skills: Human computer interaction, information visualization, interest in personal health, web programming, passion to succeed in multidisciplinary work
Suitable for: Master Student. Please contact Onur (above) or pearl.pu@epfl.ch along with your CV. 

Predicting Seizures in EEG recordings

Duration: One Semester
Goals: Create and evaluate an EEG-based seizure forecasting system.
Responsible TA: Igor Kulev (igor DOT kulev AT epfl.ch)
Student Name: Yuguang Yao (exchange student from Tsinghua University)
Keywords: time series, classification, forecasting, healthcare
Abstract:

Epilepsy afflicts nearly 1% of the world’s population, and is characterized by the occurrence of spontaneous seizure. Seizure forecasting systems have the potential to help patients with epilepsy lead more normal lives. In order for EEG-based seizure forecasting systems to work effectively, computational algorithms must reliably identify periods of increased probability of seizure occurrence. If these seizure-permissive brain states can be identified, devices designed to warn patients of impeding seizures would be possible. Patients could avoid potentially dangerous activities like driving or swimming, and medications could be administered only when needed to prevent impending seizures, reducing overall side effects. In 2014 and 2016 Kaggle completed two seizure prediction challenges. The first challenge primarily involved long-term electrical brain activity recordings from dogs. The second challenge focuses on seizure prediction using long-term electrical brain activity recordings from humans obtained from the world-first clinical trial of the implantable NeuroVista Seizure Advisory System. In this project you will apply and compare different methods on the EEG data obtained from both Kaggle challenges.

The responsible student will:

  • Survey time series classification techniques
  • Apply existing techniques on the EEG data
  • Analyze the performance of these techniques
Related Skills: Knowledge in Data Mining and/or Machine Learning; Programming skills
Suitable for: Master Student

Gamified Food Logging System

Intended for: Master project or thesisnew
Goals: Develop a playful mobile app motivating its users to log their food intake over a long period of time.
Supervisor: Dr. Pearl Pu
Student Name: Open
Keywords: Gamification, Prototyping, Nutrition, Well-being, User Study
Abstract:

Unbalanced diet is a major risk for chronic diseases such as cardiovascular disease, metabolic diseases, kidney diseases, cancer and neurodegenerative diseases. Diet is complex and rapidly changing. In addition to inter-person variability in dietary patterns there is important intra-person variability, including day-to-day and seasonable variability. Current methods to capture dietary intakes in epidemiologic studies include food-frequency questionnaires, 7-day food records and 24-hour recall. These methods are expensive to conduct, cumbersome for participants to use, and prone to reporting errors.

In this project, your goal is to re-design the experience of diet reporting. You will develop a mobile app to provide a joyful experience for users to log their food intake over a long period of time. As a first step, a survey of gamification design for such apps will be conducted, followed by the identification of successful criteria. Based on such findings, you will then apply design-thinking methods to create several solutions that satisfy both the design context and the criteria. After several iterations, the design will evolve into a highly interactive prototype before it is tested by real users. Other techniques used include stakeholder analysis, user empathy, experience mapping, and ideation of design solutions.

Related Skills: Design Thinking; Principles of Human-Computer Interaction; Mobile app development experience is a plus; Interest in Well-Being, Nutrition, or Gamification
Suitable for: Master students at their final stage of studies. Please send email to pearl pu along with a copy of your CV. 

Happy Food: Exploring Effects of Nutrition on Emotional Well-being

Duration: One Semester
Goals: Analyze relations between nutrition and emotional well-being based on the experiences reported in social media.
Responsible TA: Pearl Pu
Student Name: Othman Benchekroun
Keywords: Emotion Recognition, Twitter, Data Analysis, Statistics, Social Media Analysis, Nutrition, Well-being
Abstract:

Nowadays, much about human behavior can be discovered from their online traces in social media. People describe their lives, personal events, their reactions to products and global events, and also reveal their eating preferences. Research studies suggest that having a healthier lifestyle, including eating healthier food, can improve personal well-being and make a person happier. This project will analyze the relations between nutrition and emotional well-being as detected from social media. It will aim to derive more fine-grained patterns of relations between the products we eat and the emotions we experience.

The responsible student will:

  • Survey the state-of-the-art methods in text-based emotion recognition and related work on personal well-being relation with nutrition
  • Collect the tweets for studying relations between reported emotions and mentioned food types
  • Adapt (and potentially improve) existent tools for emotion recognition and food mention classification to extract required information from the collected tweets
  • Perform statistical data analysis to discover patterns of relations between emotions and specific food types
Related Skills: Programming skills; Statistics; Basic knowledge of Data Mining and/or Machine Learning; Interest in Social Media Analysis, and/or Computational Linguistics
Suitable for: Master Student

Evaluating Interfaces of Visual Analytic Tools

Title: Evaluating Interfaces of Visual Analytic Tools
Goals: Facilitate visualization techniques to explore “big data”, and provide a coherent method to evaluate information visualization tools.
Responsible TA: Onur Yuruten
Student Name: Taken
Keywords: Visual analytics, visualisation, interface evaluation
Abstract:

The amount of data generated in scientific studies (such as in life sciences and pervasive healthcare applications) is growing to an extent that it will be too time consuming, if not completely impractical, to apply manual analysis alone to derive significant conclusions and to verify hypotheses. To address this problem, many studies aim to deliver information visualization tools to aid scientists to explore their data. However, the information visualization field lacks a common methodology to evaluate and compare such interfaces for their usefulness and usabilities. This is an excellent opportunity to investigate existing methods, and either determine the best method, or if possible, find a way to unify them.

The responsible student will:

  • Survey information visualization techniques, and qualitative and quantitative evaluation methods
  • Develop an information visualization tool (or improve an existing interface) with algorithmic functionalities
  • Employ the evaluation techniques to validate the tool, and elaborate on the usefulness of each technique
Related Skills: Web development (Javascript, HTML, PHP, SQL); Visualization libraries for Javascript (such as D3, Rickshaw, etc.)
