In this part 1 presentation, I have attempted to provide a '30,000 feet view' of BERT (Bidirectional Encoder Representations from Transformer) - a state of the art Language Model in NLP with high level technical explanations. I have attempted to collate useful information about BERT from various useful sources.
This document discusses natural language processing (NLP) from a developer's perspective. It provides an overview of common NLP tasks like spam detection, machine translation, question answering, and summarization. It then discusses some of the challenges in NLP like ambiguity and new forms of written language. The document goes on to explain probabilistic models and language models that are used to complete sentences and rearrange phrases based on probabilities. It also covers text processing techniques like tokenization, regular expressions, and more. Finally, it discusses spelling correction techniques using noisy channel models and confusion matrices.
BERT is a deeply bidirectional, unsupervised language representation model pre-trained using only plain text. It is the first model to use a bidirectional Transformer for pre-training. BERT learns representations from both left and right contexts within text, unlike previous models like ELMo which use independently trained left-to-right and right-to-left LSTMs. BERT was pre-trained on two large text corpora using masked language modeling and next sentence prediction tasks. It establishes new state-of-the-art results on a wide range of natural language understanding benchmarks.

Chat bot making process using Python 3 & TensorFlowJeongkyu Shin
Recently, chat bot has become the center of public attention as a new mobile user interface since 2015. Chat bots are widely used to reduce human-to-human interaction, from consultation to online shopping and negotiation, and still expanding the application coverage. Also, chat bot is the basic of conversational interface and non-physical input interface with combination of voice recognition.
Traditional chat bots were developed based on the natural language processing (NLP) and bayesian statistics for user intention recognition and template-based response. However, since 2012, accelerated advance in deep-learning technology and NLPs using deep-learning opened the possibilities to create chat bots with machine learning. Machine learning (ML)-based chat bot development has advantages, for instance, ML-based bots can generate (somewhat non-sense but acceptable) responses to random asks that has no connection with the context once the model is constructed with appropriate learning level.
In this talk, I will introduce the garage chat bot creation process step-by-step. I share the idea and implementations of multi-modal machine learning model with context engine and conversion engine. Also, how to implement Korean natural language processing, continuous conversion and tone manipulation is also discussed.
Chat bot (챗 봇)은 2015년부터 모바일을 중심으로 새로운 사용자 UI로 주목받고 있다. 챗 봇은 상담시 인간-인간 인터랙션을 줄이는 용도부터 온라인 쇼핑 구매에 이르기까지 다양한 분야에 활용되고 있으며 그 범위를 넓혀 나가고 있다. 챗 봇은 대화형 인터페이스의 기초이면서 동시에 (음성 인식과 결합을 통한) 무입력 방식 인터페이스의 기반 기술이기도 하다.
기존의 챗 봇들은 자연어 분석과 베이지안 통계에 기반한 사용자 의도 패턴 인식과 그에 따른 템플릿 응답을 기본 원리로 하여 개발되었다. 그러나 2012년 이후 급속도로 발전한 딥러닝 및 그에 기초한 자연어 인식 기술은 기계 학습을 이용해 챗 봇을 만들 수 있는 가능성을 열었다. 기계학습을 통해 챗 봇을 개발할 경우, 충분한 학습도의 모델을 구축한 후에는 학습 데이터에 따라 컨텍스트에서 벗어난 임의의 문장 입력에 대해서도 적당한 답을 생성할 수 있다는 장점이 있다.
이 발표에서는 Python 3 및 TensorFlow를 이용하여 딥러닝 기반의 챗 봇을 만들 경우에 경험하게 되는 문제점들 및 해결 방법을 다룬다. 봇의 컨텍스트 엔진과 대화 엔진간의 다형성 모델을 구현하고 연결하는 아이디어와 함께 자연어 처리 및 연속 대화 구현, 어법 처리 등을 어떻게 모델링할 수 있는 지에 대한 아이디어 및 구현과 팁을 공유하고자 한다.

Recurrent neural networks (RNNs) are well-suited for analyzing text data because they can model sequential and structural relationships in text. RNNs use gating mechanisms like LSTMs and GRUs to address the problem of exploding or vanishing gradients when training on long sequences. Modern RNNs trained with techniques like gradient clipping, improved initialization, and optimized training algorithms like Adam can learn meaningful representations from text even with millions of training examples. RNNs may outperform conventional bag-of-words models on large datasets but require significant computational resources. The author describes an RNN library called Passage and provides an example of sentiment analysis on movie reviews to demonstrate RNNs for text analysis.
This was presented to software developers with the goal of introducing them to basic machine learning workflow, code snippets, possibilities and state-of-the-art in NLP and give some clues on where to get started.
The document provides an overview of the state of natural language processing (NLP) and Amazon's NLP offering Amazon Comprehend. It discusses the evolution of NLP from rule-based systems to modern neural models like BERT and Transformer and the increasing complexity of NLP tasks.

The document discusses two paradigms for natural language processing: knowledge engineering and machine learning. It provides examples of how each approach handles tasks like parsing, translation, and question formation. While knowledge engineering relies on hand-coded rules and representations, machine learning trains statistical models on large datasets. The document also notes Microsoft's interests in using NLP for applications like search and summarization.

A train carriage containing controlled nuclear materials was stolen in Cincinnati today. Its
whereabouts are unknown.
The incident occurred on the downtown train line, which runs from Covington and Ashland stations.
In an email to Ohio news outlets, the U.S. Department of Energy said it is working with the Federal Railroad
Administration to find the thief.
“The theft of this nuclear material will have significant negative consequences on public and environmental
health, our workforce and the economy of our nation,” said Tom Hicks, the U.S. Energy Secretary, in a statement.
“Our top priority is to secure the theft and ensure it doesn’t happen again.”
The stolen material was taken from the University of Cincinnati’s Research Triangle Park nuclear research site,
according to a news release from Department officials.
The Nuclear Regulatory Commission did not immediately release any information.
According to the release, the U.S. Department of Energy’s Office of Nuclear Material Safety and Security is leading
