Research Trends

  • Method to create colloidal diamonds developed
    The colloidal diamond could make light waves as useful as electrons in computing, and hold promise for a host of other applications. Researchers have devised a new process for the reliable self-assembly of colloids in a diamond formation that could lead to cheap, scalable fabrication of such structures.
  • Proof-of-concept for a new ultra-low-cost hearing aid for age-related hearing loss
    A new ultra-affordable and accessible hearing aid made from open-source electronics could soon be available worldwide, according to a new study.
  • Flood risks: More accurate data due to COVID-19
    Emerging use of Global Navigation Satellite System (GNSS) makes it possible to continuously measure shallow changes in elevation of Earth surface. A study now shows that the quality of these measurements may have improved significantly during the pandemic, at least at some stations. The results show which factors should be considered in the future when […]
  • This tiny device can scavenge wind energy from the breeze you make when you walk
    Most of the wind available on land is too gentle to push commercial wind turbine blades, but now researchers have designed a kind of ‘tiny wind turbine’ that can scavenge wind energy from breezes as little as those created by a brisk walk. The method is a low-cost and efficient way of collecting light breezes […]
  • Nanostructures with a unique property
    Nanoscale vortices known as skyrmions can be created in many magnetic materials. For the first time, researchers have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have succeeded in visualizing this phenomenon using neutron scattering.
  • Meditation for mind-control
    Scientists have discovered that mindful meditation can help subjects learn and improve the ability to mind-control brain computer interfaces (BCIs).
  • Shadow of black hole in M87 galaxy is wobbling and has been for a while
    A new analysis reveals the behavior of the supermassive black hole in the center of the M87 galaxy across multiple years, indicating the crescent-like shadow feature appears to be wobbling.
  • A cheaper, faster COVID-19 test
    Researchers have developed a method for fast, cheap, yet accurate testing for COVID-19 infection. The method simplifies and frees the testing from expensive reaction steps, enabling upscaling of the diagnostics.

Research on Progress

  • Chatbot Development using Hybrid Deep Learning Techniques

    Conversational models are a hot topic in artificial intelligence research. It can be found in a variety of settings, including online customer service applications and online helpdesks. This conversational agent (Chabot) is powered by retrieval-based models, which reply queries based on predefined responses. Questions and answers were provided and relational database queries are being used. The models are sufficient, however, they are not robust enough for more general use-cases. Recently, the deep learning (Recurrent Neural Network) boom has allowed for powerful generative models which mark a large step towards multi-domain generative conversational models. Despite these, RNN also has its own weakness when applied to dialog systems: the generated sentence tends to be short, universal, and meaningless or we call it “low substance”. This is probably because chatbot-like dialogs are highly diversified and a query may not convey sufficient information for the reply. The Recurrent Embedding Dialog Policy (REDP) is a model which designed to handle uncooperative behaviour of the user. This model is not rich of data compared to the first two models. Because of these problems in each model, this results to the inconsistency of the chatbot. Thus, in this study the author proposed a model ensemble of Retrieval, Generative, and Recurrent Embedding –Based Dialog System called “RGR-Based Dialog System”. Initial result of the study shows that feeding the retrieved candidate to generative model can resolve the “low substance” problem and combining the three (3) models can resolved the inconsistency of the conversational AI.
