ABSTRACT
Wireless spectrum is well recognized as the Black Gold in the 21th century. The requirement of obtaining wide-band wide-area wireless spectrum state in an accurate, timely, comprehensive, and cost-efficient manner poses critical technical challenges and drives the recent advances in wireless spectrum data analytics. This speech will present an overview of our recent work on machine learning-enabled wireless spectrum data analytics, which will mainly consist of three parts. The first part focuses on robust cooperative spectrum sensing, which is a reactive manner to obtain the wireless spectrum state via various signal detection and data fusion methods. Kernel-based learning will be introduced as an effective tool to tackle with Byzantine attacks. The second one will be online multi-dimensional spectrum prediction, which is a proactive manner to obtain the wireless spectrum state via kinds of statistical inference techniques. The low-rank and sparsity in spectrum matrix or spectrum tensor will be expoited to faciliate the active prediction. Deep learning will also be taliored to show its superority in spectrum prediction. The third part will depict several potential applications, including dynamic spectrum sharing in future wireless networks, intelligent spectrum management in UAV or Drones-enabled wireless communications, big spectrum data analytics-supported cogntive internet of things, to name a few.

ABSTRACT
The human intelligence can be divided into three stages: computation, perception and cognitive intelligence. Artificial intelligence is a field was founded on the claim that human intelligence “can be so precisely described that a machine can be made to simulate it”. For computation intelligence, humans have been completely defeated by machines. In recent years, with the help of deep learning and big data, machines are chipping away at human's lead in perception intelligence. However, the cognitive intelligence has always been thought of a unique ability of humans. And, the natural language or human language is the most important part of perception intelligence. So, the natural language processing, which employs computational techniques for the purpose of learning, understanding, and producing human language content, is the highest level of artificial intelligence. Early computational approaches to language research focused on automating the analysis of the linguistic structure of language and developing basic technologies such as machine translation, question and answering. Today’s researchers refine and make use of such tools in real-world applications, creating spoken dialogue systems and speech-to-speech translation engines, mining social media for information about health or finance, and identifying sentiment and emotion toward products and services. We will describe successes and challenges in this rapidly advancing area.
