Recognizing Multi-talker Speech with Permutation Invariant Training
In this paper, we propose a novel technique for direct recognition of
multiple speech streams given the single channel of mixed speech, without first
separating them. Our technique is based on permutation invariant training (PIT)
for automatic speech recognition (ASR). In PIT-ASR, we compute the average
cross entropy (CE) over all frames in the whole utterance for each possible
output-target assignment, pick the one with the minimum CE, and optimize for
that assignment. PIT-ASR forces all the frames of the same speaker to be
aligned with the same output layer. This strategy elegantly solves the label
permutation problem and speaker tracing problem in one shot. Our experiments on
artificially mixed AMI data showed that the proposed approach is very
promising.Comment: 5 pages, 6 figures, InterSpeech201
A Different Type of Crisis
The past 30 years saw China rising from a populous developing country to a formidable world power with an economy second only to the United States. While the economic development is surging ahead, the society's value system seems to be shaky, if not collapsed. This project examines the reasons why this is happening
Taiwan Election: Why the KMT Lost So Miserably?
Taiwan had its largest local election in November 2014 with a total of 11,130 positions of local government and local legislative offices decided by the voters. The ruling party suffered a humiliating defeat. This project attempts to analyze the reasons for the defeat and future implications of this election to Taiwan and mainland China
Comparative Analysis of the Core Values among Different Groups of Chinese People
Values are principles that guide people’s behavior. Values are formed by life experiences influenced by one’s family, school, culture, and society. Some values are universal and others are culturally distinct. This project intends to examine if people change their values as they go through different stages of life, especially for students who grew up in China and come to American universities for education. Do they keep their values intact or do their values change? If their values change, in what areas do those changes occur and to what degree do they occur? This project studies the values held by Chinese students in China, Chinese students studying in the United States, and students of Chinese origin
The Lord of the Rings Trilogy Exceeds in Cultivating Fine Art Through the Medium of Film
The Lord of the Rings film trilogy transgresses the common movie. Through the medium of film, it replaces an average movie experience by expressing and cultivating fine arts such as music, writing, and conceptual art, to bring one of the most rich and influential stories of our time onto the screen
Public Diplomacy and Image Building: A Case of China
This paper examines the relationship between China’s public diplomacy and image building in the United States, and the subsequent impact on China’s foreign policy in the U.S. and in some other parts of the world. As the second largest economy in the world today, China is playing an increasingly important role in the global arena. China’s weight is felt not only in economics and business, but also in politics and international relations. With the growing influence China exerts on global issues, China also feels the necessity to create a better image for itself on the world stage. While specific figures are hard to obtain, by any estimate, China has spent hundreds of millions of dollars in the past few years on promoting China and projecting a positive image of itself to the world. The aggressive public diplomacy campaigns are launched on multiple fronts and in different countries around the world. Examples include promotional visual campaigns in Times Square in New York City, the launch of the China Xinhua News Network Corporation in the United States, and the establishment of the Confucius Institutes around the globe. We explore all these examples in our analysis
