Natural Is The Best: Model-Agnostic Code Simplification for Pre-trained Large...YanKing2
Pre-trained Large Language Models (LLM) have achieved remarkable successes in several domains. However, code-oriented LLMs are often heavy in computational complexity, and quadratically with the length of the input code sequence. Toward simplifying the input program of an LLM, the state-of-the-art approach has the strategies to filter the input code tokens based on the attention scores given by the LLM. The decision to simplify the input program should not rely on the attention patterns of an LLM, as these patterns are influenced by both the model architecture and the pre-training dataset. Since the model and dataset are part of the solution domain, not the problem domain where the input program belongs, the outcome may differ when the model is trained on a different dataset. We propose SlimCode, a model-agnostic code simplification solution for LLMs that depends on the nature of input code tokens. As an empirical study on the LLMs including CodeBERT, CodeT5, and GPT-4 for two main tasks: code search and summarization. We reported that 1) the reduction ratio of code has a linear-like relation with the saving ratio on training time, 2) the impact of categorized tokens on code simplification can vary significantly, 3) the impact of categorized tokens on code simplification is task-specific but model-agnostic, and 4) the above findings hold for the paradigm–prompt engineering and interactive in-context learning and this study can save reduce the cost of invoking GPT-4 by 24%per API query. Importantly, SlimCode simplifies the input code with its greedy strategy and can obtain at most 133 times faster than the state-of-the-art technique with a significant improvement. This paper calls for a new direction on code-based, model-agnostic code simplification solutions to further empower LLMs.

Exploring Deep Learning Models for Image Recognition: A Comparative Reviewsipij
Image recognition, which comes under Artificial Intelligence (AI) is a critical aspect of computer vision,
enabling computers or other computing devices to identify and categorize objects within images. Among
numerous fields of life, food processing is an important area, in which image processing plays a vital role,
both for producers and consumers. This study focuses on the binary classification of strawberries, where
images are sorted into one of two categories. We Utilized a dataset of strawberry images for this study; we
aim to determine the effectiveness of different models in identifying whether an image contains
strawberries. This research has practical applications in fields such as agriculture and quality control. We
compared various popular deep learning models, including MobileNetV2, Convolutional Neural Networks
(CNN), and DenseNet121, for binary classification of strawberry images. The accuracy achieved by
MobileNetV2 is 96.7%, CNN is 99.8%, and DenseNet121 is 93.6%. Through rigorous testing and analysis,
our results demonstrate that CNN outperforms the other models in this task. In the future, the deep
learning models can be evaluated on a richer and larger number of images (datasets) for better/improved
results.

9. New Rendering Model: Layers (2/4)
1. Avoid unnecessary repainting
- If yellow and red have their own layers, then nothing needs
"repainting" while this example animates.
2. Makes some features more efficient or practical
- Including: Scrolling, 3D CSS(translate3d, …), opacity, filters, WebGL, etc.

2. Why Multi Process Architecture?
기존 브라우저의 문제점
• 현재(크롬 제작 당시)의 브라우저는 과거의 OS와 비슷한 구조
• 과거의 OS는 단일 사용자, 협조적 멀티 태스킹 시스템
• 이와 같은 시스템에서, 어떤 어플리케이션의 문제는 OS 전체의 안정성에 영향을 미침
• 단일 프로세스 모델의 브라우저에서는 한 페이지의 문제가 브라우저 전체에 문제를 일으킴
문제해결을 위한 접근
• 절대적으로 안정적인 렌더링 엔진을 만드는 것은 거의 불가능함
• 최근의 OS는 각 어플리케이션을 고립시킴으로써 특정 어플리케이션의 문제가 시스템 전체의 안정
성에 영향을 미치지 않도록 하며, 사용자 각자의 데이터를 보호하고 있음

10. The Future of WebView?
“Under active debate at the moment” (2014/11)
1. Opposing use cases
1) WebView as a browser-in-a-box, Vs
2) WebView as one tool in a hybrid app toolset
2. Opposing update priorities
1) App developers want the latest features and
performance improvements
2) They also want stability to the point of bug-for-bug
compatibility
