    • Learning discriminative models with incomplete data 

      Kapoor, Ashish, 1977- (Massachusetts Institute of Technology, 2006)
      Many practical problems in pattern recognition require making inferences using multiple modalities, e.g. sensor data from video, audio, physiological changes etc. Often in real-world scenarios there can be incompleteness ...
    • Learning the meaning of music 

      Whitman, Brian A. (Brian Alexander) (Massachusetts Institute of Technology, 2005)
      Expression as complex and personal as music is not adequately represented by the signal alone. We define and model meaning in music as the mapping between the acoustic signal and its contextual interpretation - the 'community ...
    • Lens x block : World as construction kit 

      Silver, Jay (Jay Saul) (Massachusetts Institute of Technology, 2014)
      Purpose and meaning of the physical world can be re-assigned and re-made by individuals as they go rather than being pre-fixed by people who came before them. But this mindset is more rare than it should be if we want an ...
    • Lensing Machines : representing perspective in machine learning 

      Dinakar, Karthik (Massachusetts Institute of Technology, 2017)
      Generative models are venerated as full probabilistic models that randomly generate observable data given a set of latent variables that cannot be directly observed. They can be used to simulate values for variables in the ...
    • Liberated pixels : alternative narratives for lighting future cities 

      Seitinger, Susanne, 1978- (Massachusetts Institute of Technology, 2010)
      Lighting and illuminated displays shape our relations to urban environments and to one another at night and increasingly during the day by transforming what Kevin Lynch referred to as the "image of the city" (1964). Today, ...
    • Life patterns : structure from wearable sensors 

      Clarkson, Brian Patrick, 1975- (Massachusetts Institute of Technology, 2003)
      In this thesis I develop and evaluate computational methods for extracting life's patterns from wearable sensor data. Life patterns are the reoccurring events in daily behavior, such as those induced by the regular cycle ...
    • Local multiagent control in large factored planning Problems 

      Robbel, Philipp (Massachusetts Institute of Technology, 2016)
      Many problems of economic and societal interest in today's world involve tasks that are inherently distributed in nature. Whether it be the efficient control of robotic warehouses or delivery drones, distributed computing ...
    • Loco-Radio : designing high-density augmented reality audio browsers 

      Li, Wu-Hsi (Massachusetts Institute of Technology, 2014)
      In this dissertation research, we explore ways of using audio on AR applications, as it is especially suitable for mobile users when their eyes and hands are not necessarily available and they have limited attention capacity. ...
    • Low frequency indoor radiolocation 

      Reynolds, Matthew S. (Matthew Stephen), 1975- (Massachusetts Institute of Technology, 2003)
      This thesis concerns the application of electromagnetic wave propagation to the problem of indoor radiolocation. Determining the location of people and objects relative to their environment is crucial for asset tracking, ...
    • Low-cost electromagnetic tagging : design and implementation 

      Fletcher, Richard R. (Richard Ribon) (Massachusetts Institute of Technology, 2002)
      Several implementations of chipless RFID (Radio Frequency Identification) tags are presented and discussed as low-cost alternatives to chip-based RFID tags and sensors. An overview of present-day near-field electromagnetic ...
    • Machine perception and learning of complex social systems 

      Eagle, Nathan Norfleet (Massachusetts Institute of Technology, 2005)
      The study of complex social systems has traditionally been an arduous process, involving extensive surveys, interviews, ethnographic studies, or analysis of online behavior. Today, however, it is possible to use the ...
    • Machine therapy 

      Dobson, Kelly E. (Kelly Elizabeth), 1970- (Massachusetts Institute of Technology, 2007)
      Machine Therapy is a new practice combining art, design, psychoanalysis, and engineering work in ways that access and reveal the vital, though often unnoticed, relevance of people's interactions and relationships with ...
    • Making machines that make : object-oriented hardware meets object-oriented software 

      Peek, Nadya (Nadya Meile) (Massachusetts Institute of Technology, 2016)
      Rapid prototyping has been in the limelight for the past decade. 3D printers have an evocative name that promises production of complex parts on demand. Yet current practice doesn't quite deliver on these promises of ...
    • Making make-throughs : documentation as stories of design process 

      Tseng, Tiffany (Massachusetts Institute of Technology, 2016)
      Much of what we design today is mediated by digital processes, from digital tools and software used to create tangible and virtual artifacts, to online resources and communities that enable people to exchange design ...
    • Materializing interaction 

      Coelho, Marcelo (Massachusetts Institute of Technology, 2013)
      At the boundary between people, objects and spaces, we encounter a broad range of surfaces. Their properties perform functional roles such as permeability, comfort or illumination, while conveying information such as an ...
    • Me, myself, and my hyperego : understanding people through the aggregation of their digital footprints 

      Zinman, Aaron Robert (Massachusetts Institute of Technology, 2011)
      Every day, millions of people encounter strangers online. We read their medical advice, buy their products, and ask them out on dates. Yet our views of them are very limited; we see individual communication acts rather ...
    • Measuring college students' sleep, stress, mental health and wellbeing with wearable sensors and mobile phones 

      Sano, Akane (Massachusetts Institute of Technology, 2016)
      This thesis carries out a series of studies and develops a methodology and tools to measure and analyze ambulatory physiological, behavioral and social data from wearable sensors and mobile phones with trait data such as ...
