Analyze the results of image classifier trained on images before and after conversion via deep learning
Fang-Yuan Huang;Sheng-Lung Huang;Snow H. Tseng

A pre-train image conversion scheme is adapted into an image classifier network of skin cancers. The network is separately trained on both OCT images before and after conversion into H&E-liked images. We compared the training results to anaylize factors which influenced the accuracy and discovered some insight of deep learning.

Analyzing the feasibility to suppress scattering effect in turbid media via partial optical phase conjugation
Pei-Lin Chou;Snow H. Tseng

Utilizing pseudospectral time-domain (PSTD) simulation technique, we model the phenomenon of optical phase conjugation (OPC). Specifically, we investigate the feasibility to focus light with imprecise OPC information. Research findings may provide essential information to determine the contribution of certain factors in focusing light in turbid media.

The lossy mode resonance sensor with a self-heating electrode to immobilize bovine serum albumin (BSA) was proposed and studied. The sensor is a planar waveguide coated with a thin film of ITO. With controlling the external voltage to generate heat through ITO, the LMR wavelength shift is more obvious.

Evaluation of ECMO Patients’ Recovery Using Functional Near-Infrared Spectroscopy and Machine Learning
Ting-Wei Chiang;Yi-Chih Chen;Tzu-Hsin Fan;Chia-Wei Sun

Extracorporeal membrane oxygenation (ECMO) is a lifesaving rescue treatment in refractory respiratory or cardiac failure. However, no guidelines or reliable clinical parameters are available for adjusting ECMO treatment in terms of machine settings. Therefore, this study applied near-infrared spectroscopy (NIRS) to observe these patients' global circulatory status.

Intelligent Identification of Few-layers MoS2
yu yang Chen;Kai Chun Li;Hsiang Chen Wang

The large-area characterization, precision, intelligent automation, and high-efficiency detection of nanostructures for 2D materials have not yet reached an industrial level. We propose deep neural network, one-dimensional (1D) convolutional neural network to explore the correlation between the accuracy of model recognition and the optical characteristics of few-layers MoS2.
