[Professional - Graduate School Enrollment] Pursuing a Ph.D. in Middle Age

Insung Lee shares his challenges and courage during his doctoral program Introduction In my early 30s, when I started my Master's program, I was full of enthusiasm and passion . I thought, “If I learn this, I’ll become a better version of myself.” At that time, I was driven by the desire to solve problems I encountered at work, so I decided to deepen my knowledge through academics. There were challenges along the way, but I believed that I could handle anything back then. However, at 41, when I think about pursuing a Ph.D. again, I find myself facing the question: "Is this the right path?" The question of what it would mean to go back to studying at this age looms over me. Time is more limited now, and there are financial pressures, family obligations, and the demands of my current job— all the realities that make it seem like a much tougher decision. 1. The Struggles of Aging and Reflection In my younger years, I believed that as long as I had passion and purpose ,...

딥 러닝(Deep Learning) 이란? 데이터에 존재하는 패턴을 복잡한 다계층 네트워크로 모델화하는 머신러닝의 일종 Deep learning 은 문제를 모델화하는 방법으로, 컴퓨터 비전과 자연어 처리 같은 어려운 문제 또한 해결 가능 합니다. 트레이닝 할 모델의 Input 과 Output 사이에 숨겨진 계층(hidden layer)이 한 개 이상 존재 해야 하며.  Deep learning 은 심층 신경망(Deep Neural Networks, DNN)을 사용하는 것을 의미합니다..  참고로 신경망 외에도, 다른 종류의 숨겨진 계층을 사용해 딥 러닝을 구현하는 알고리즘들이 소수 존재 합니다.. 딥러닝 모델 트레이닝에는 아주 높은 컴퓨팅 성능이 필요 하며, 딥 러닝 모델 해석이 어려  것이 대표적인 단점 입니다.  1. 딥 러닝 vs 머신러닝 딥 러닝은 머신러닝의 한 종류로 볼 수 있습니다. 2. 딥 러닝 애플리케이션 분야 자연어 처리 (Natural Language Processing, NLP)가 대표적인 예로 자동 요약(Automatic Summarization) 대용어 해소(Co-reference Resolution) 담화 분석(Discourse Analysis) 형태론적 구분(morphological segmentation) 개체명 인식(Named Entity Recognition, NER) 자연어 생성 자연어 이해 POS(Part of Speech) 태깅 감성 분석(sentiment analysis) 스피치 인식(speech recognition)  등이 있다. 이미지 관련 문제의 경우 객체 탐지(Object detection) 객체 분할(Object segmentation) 이미지 스타일 전이(Image style transfer) 이미지 색상화(Image colorization) 이미지 재구성(Image reconstruction) 이미지 슈퍼레졸루션(Image super-resolution) 이미지 ...

AI (Artificial Intelligence) Curriculum - Modern Approaches

For this subject, I believe it is necessary to base the learning on the table of contents of a specific book, which is incomparable to any other curriculum. Therefore, I think it is important to introduce the table of contents of the book itself. However, for professionals who may not have the time to study all the material, I plan to focus on and provide detailed learning for the most essential topics.
