Fakestack: Hierarchical Tri-Bert-Cnn-Lstm Stacked Model For Effective Fake News Detection

Faculty, Staff and Student Publications

False news articles pose a serious challenge in today's information landscape, impacting public opinion and decision-making. Efforts to counter this issue have led to research in deep learning and machine learning methods. However, a gap exists in effectively using contextual cues and skip connections within models, limiting the development of comprehensive detection systems that harness contextual information and vital data propagation. Thus, we propose a model of deep learning, FakeStack, in order to identify bogus news accurately. The model combines the power of pre-trained Bidirectional Encoder Representation of Transformers (BERT) embeddings with a deep Convolutional Neural Network (CNN) having skip …

Which U.S. Executive Agency Is The Most Practical To Promulgate Space Debris Mitigation Regulations, And How Will The Space Debris Legal Framework Further Develop?, Tate Garvin Few

Theses and Dissertations

There is much dispute over which agency should take charge of creating and enforcingspace debris regulations. The controversy stems from the highly underdeveloped legal framework that is limited to the IADC guidelines, the Orbital Debris Mitigation Standard Practices (ODMSP), and Space Policy Directive-3. Currently, the Federal Communications Commission is attempting to take the lead role in this effort by establishing the new 5-year space debris disposal rule. However, it is argued that Congress did not declare it to be within their jurisdictional purview. Congress has not yet explicitly stated their intent to have a centralized authority in establishing relevant regulations …
