The document summarizes a research paper that compares the performance of MLP-based models to Transformer-based models on various natural language processing and computer vision tasks. The key points are:
1. Gated MLP (gMLP) architectures can achieve performance comparable to Transformers on most tasks, demonstrating that attention mechanisms may not be strictly necessary.
2. However, attention still provides benefits for some NLP tasks, as models combining gMLP and attention outperformed pure gMLP models on certain benchmarks.
3. For computer vision, gMLP achieved results close to Vision Transformers and CNNs on image classification, indicating gMLP can match their data efficiency.
The document discusses the rights of data subjects under the EU GDPR, particularly regarding automated decision-making and profiling. It outlines conditions under which such decisions can be made, emphasizing the need for measures that protect the data subjects' rights and freedoms. Additionally, it includes references to various machine learning and artificial intelligence interpretability frameworks and studies.
The document explores contrastive self-supervised learning, discussing its methodologies that reduce human annotation costs while promoting general representation learning.

Crowd-Powered Parameter Analysis for Visual Design Exploration (UIST 2014)Yuki Koyama
?
This document describes a crowd-powered approach to analyzing design spaces and exploring visual design parameters. It involves analyzing a design space by sampling parameter sets and gathering pairwise comparisons from crowd workers to estimate goodness values for points. User interfaces like a smart suggestion interface and VisOpt slider are introduced to facilitate design exploration based on the estimated goodness function.
The document consists of a collection of research works and publications related to various topics in medical imaging, 3D modeling, and semantic editing, featuring significant contributions from different authors. It highlights developments in tools and techniques for interactive deformation, crowd-powered design analysis, and the integration of semantic attributes in content creation. Additionally, it presents findings and methodologies from conferences such as SIGGRAPH and UIST, emphasizing the relationship between design elements and user interactions.
Our method performs shape matching for example-based elastic materials. It matches shapes by finding a linear transformation including rotation and stretching that aligns the example shape to the target shape. This process is faster than the finite element method, taking milliseconds versus seconds. However, it is less physically accurate for simulating deformations. The method works best for thin structures like cloth or hair, and could be improved by increasing physical accuracy while maintaining speed.
View-Dependent Control of Elastic Rod Simulation for 3D Character Animation (...Yuki Koyama
?
This document presents a method for view-dependent control of elastic rod simulation for 3D character animation. The method extends view-dependent geometry techniques to allow rods like hair and ears to change shape based on the camera view during physical simulation. Weights are calculated from example poses and view directions to blend between a base pose and example poses. A suppression algorithm is used to separately update rod velocities and positions in order to reduce unwanted "ghost momentum" caused by view changes without fully damping the simulation. The method allows more stylized 2D-like shapes during animation but has limitations including incomplete suppression of ghost forces and increased computation costs.
Visualization of Supervised Learning with {arules} + {arulesViz}Takashi J OZAKI
?
This document discusses visualizing supervised learning models using association rules and the arules and arulesViz packages in R. It shows how association rules generated from sample user activity data can be represented as graphs, allowing intuitive visualization of relationships between variables even in high-dimensional data. The visualizations are compared to results from GLMs and random forests to show how nodes are located based on their "closeness" in different supervised learning models. While less quantitative, this technique provides a more intuitive understanding of supervised learning that is useful for presentations.
[CHI 2016] SelPh: Progressive Learning and Support of Manual Photo Color Enha...Yuki Koyama
?
This document describes a system called SelPh that aims to support manual photo color enhancement. It proposes a "self-reinforcing" workflow where a user's manual edits are used to progressively train a preference model, which then helps support further manual enhancements. The system visualizes enhancement goodness, provides interactive optimization, allows auto-enhancements, indicates enhancement confidence levels, and references similar photos. A prototype was created and evaluated in a user study with photographers to understand how the system could help with enhancing many photos.
