Solid Ink Laser Patterning for High‐Resolution Information Labels with Supervised Learning Readout
نویسندگان
چکیده
Tagging, tracking, or validation of products are often facilitated by inkjet-printed optical information labels. However, this requires thorough substrate pretreatment, ink optimization, and lacks in printing precision/resolution. Herein, a method based on laser-driven deposition solid polymer that allows for various substrates without pretreatment is demonstrated. Since the process has precision <1 µm, it can introduce concept sub-positions with overlapping spots. This enables high-resolution fluorescent labels comparable spot-to-spot distance down to 15 µm (444,444 spots cm−2) rapid machine learning-supported readout low-resolution fluorescence imaging. Furthermore, defined thickness printed be used fabricate multi-channel Additional stored different channels hidden topography channel label independent fluorescence.

Semi-Supervised Multi-Label Learning with Incomplete Labels
The problem of incomplete labels is frequently encountered in many application domains where the training labels are obtained via crowd-sourcing. The label incompleteness significantly increases the difficulty of acquiring accurate multi-label prediction models. In this paper, we propose a novel semi-supervised multi-label method that integrates low-rank label matrix recovery into the manifold ...
متن کاملFeature Learning Based Deep Supervised Hashing with Pairwise Labels
Recent years have witnessed wide application of hashing for large-scale image retrieval. However, most existing hashing methods are based on hand-crafted features which might not be optimally compatible with the hashing procedure. Recently, deep hashing methods have been proposed to perform simultaneous feature learning and hashcode learning with deep neural networks, which have shown better pe...
متن کاملSemi-Supervised Learning on an Augmented Graph with Class Labels
In this paper, we propose a novel graph-based method for semi-supervised learning. Our method runs a diffusion-based affinity learning algorithm on an augmented graph consisting of not only the nodes of labeled and unlabeled data but also artificial nodes representing class labels. The learned affinities between unlabeled data and class labels are used for classification. Our method achieves su...
متن کاملGraph-based semi-supervised learning with multiple labels
Conventional graph-based semi-supervised learning methods predominantly focus on single label problem. However, it is more popular in real-world applications that an example is associated with multiple labels simultaneously. In this paper, we propose a novel graph-based learning framework in the setting of semi-supervised learning with multiple labels. This framework is characterized by simulta...
متن کاملUsing Rule-Based Labels for Weak Supervised Learning
With access to large datasets, deep neural networks (DNN) have achieved humanlevel accuracy in image and speech recognition tasks. However, in chemistry, availability of large standardized and labelled datasets is scarce, and many chemical properties of research interest, chemical data is inherently small and fragmented. In this work, we explore transfer learning techniques in conjunction with ...
