Practical pattern-classification and knowledge-discovery problems require the selection of a subset attributes or features to represent patterns be classified. The authors' approach uses genetic algorithm select such subsets, achieving multicriteria optimization in terms generalization accuracy costs associated with features.

While some studies have proven that Swin Transformer (Swin) with window self-attention (WSA) is suitable for single image super-resolution (SR), the plain WSA ignores broad regions when reconstructing high-resolution images due to a limited receptive field. In addition, many deep learning SR methods suffer from intensive computations. To address these problems, we introduce N-Gram context low-level vision Transformers first time. We define as neighboring local windows in Swin, which differs...

Constructive learning algorithms offer an attractive approach for the incremental construction of near-minimal neural-network architectures pattern classification. They help overcome need ad hoc and often inappropriate choices network topology in that search suitable weights a priori fixed architectures. Several such are proposed literature shown to converge zero classification errors (under certain assumptions) on tasks involve binary mapping (i.e., problems involving binary-valued input...

With the proliferation of Internet and huge amount data it transfers, text summarization is becoming more important. We present an approach to design automatic summarizer that generates a summary by extracting sentence segments. First, sentences are broken into segments special cue markers. Each segment represented set predefined features (e.g. location segment, average term frequencies words occurring in number title like). Then supervised learning algorithm used train extract important...

Abstract Motivation: Automatic knowledge discovery and efficient information access such as named entity recognition relation extraction between entities have recently become critical issues in the biomedical literature. However, inherent difficulty of task, mainly caused by diversity natural language, is further compounded domain because sentences are commonly long complex. In addition, often involves modeling range dependencies, discontiguous word patterns semantic relations for which...

The construction of interaction networks between proteins is central to understanding the underlying biological processes. However, since many useful relations are excluded in databases and remain hidden raw text, a study on automatic extraction from text important bioinformatics field. Here, we suggest two kinds kernel methods for genic extraction, considering structural aspects sentences. First, improve our prior dependency by modifying function so that it can involve various substructures...

Diffusion Transformers (DiT) excel in video generation but encounter significant computational challenges due to the quadratic complexity of attention. Notably, attention differences between adjacent diffusion steps follow a U-shaped pattern. Current methods leverage this property by caching blocks, however, they still struggle with sudden error spikes and large discrepancies. To address these issues, we propose UniCP unified pruning framework for efficient generation. optimizes both...

Multi-layer networks of threshold logic units (TLU) offer an attractive framework for the design pattern classification systems. A new constructive neural network learning algorithm (DistAl) based on inter-pattern distance is introduced. DistAl constructs a single hidden layer hyperspherical neurons. Each neuron designed to determine cluster training patterns belonging same class. The weights and thresholds neurons are determined directly by comparing distances patterns. This offers...
