Long-standing research has highlighted the critical role of physical and outdoor activities for children’s health and wellbeing. During the COVID-19 pandemic, children and youth around the world experienced heightened stress and poor mental health, which coincided with a decrease in active play and increase in screen-based activities. This work aims...
Autonomous robotic agents are on their way to becoming in-home personal assistants, construction assistants, and warehouse workers. The degree of autonomy of such systems is reflected by the manner in which we specify goals to them; the abstraction of low-level commands to high-level goals goes hand-in-hand with increased autonomy. In...
Simulation has provided much design inspiration for the field of robotics. While many astute ideas can be computationally formulated, there are some good structures in animals that people call “biologically-inspired”. Many robots are designed based on natural creatures such as crabs, spiders, etc. Before we can take full advantage of...
Impedance measurements are increasingly demanded in modern CMOS sensing systems as impedance is the most common electrical signal obtained from sensors, delivering physical, chemical and biomedical quantity changes. Impedance sensing for wide interested frequency, broad dynamic range, and various sensor interfaces has numerous challenges, especially targeted in CMOS miniaturization with...
Machine Translation, the task of automatically translating between human languages has been studied for decades. This task is used to be solved by count-based statistical models, e.g. Phrase-based Statistical Machine Translation (PBSMT), which solves the translation problem by separately training a statistical language model and a translation model. Recently, Neural...
In standard training regimes, one assumes that the classes presented to a model constitute all of the classes that the model will encounter when it is deployed. In real deployment scenarios, however, a model can sometimes encounter situations or objects that it has never seen. When these scenarios are safety-critical,...
Genetic code expansion (GCE) is a technology that allows us to incorporate noncanonical amino acids (ncAAs) site-specifically into recombinant proteins using engineered translational machinery. Typically, an orthogonal aaRS/tRNA pair is engineered by directed evolution to recognize the ncAA and incorporate it at a reassigned codon while not interacting with the...
Intuitively, it seems as though natural language processing tasks might benefit from explicit representations of the syntactic and semantic properties of text. Ontonotes is a dataset which attempts to annotate texts, to represent as much as possible of the meaning of the text explicitly within the annotation. Many tools exist...
In recent years, RF (Radio Frequency) device fingerprinting using deep learning has emerged as a method of identifying devices solely by their RF transmissions. Conventional approaches to this type of device fingerprinting are not portable to different domains. That is, if a model for this purpose is trained on data...
Machine learning applied to computer architecture has rapidly transitioned from a theoretical novelty to being a driving force behind design, control, and simulation in practically all components. These machine-learning-based methodologies are further notable for their scalability to increasingly complex design challenges, which has allowed these methodologies to surpass the prior...
