Natural Language Processing Lab
Machine-translated · View original
The lab studies natural language processing, which handles text, as well as the analysis of odor information.

AboutAbout the lab
Applying techniques for processing text to the analysis of odors.
The Natural Language Processing Lab studies techniques for processing text in languages such as Japanese and English by computer.
The lab studies the classification of sentences and documents based on parameter estimation of statistical language models, and the estimation of similarity between sentences and between documents using deep learning.
Using models similar to statistical language models, the lab also works on the analysis of odor information.
Key terms
- Natural language processing
- A research field on techniques for processing text written in natural languages such as Japanese and English by computer
- Olfactory bulb
- The first brain tissue to receive odor information. It is studied by imaging the activity patterns of groups of neurons
- Odor traces
- The sources of an odor. They are the targets that the lab separates from the measurement data of multi-channel odor sensors and visualizes
ResearchResearch themes
Natural language processing is a research field on techniques for processing text written in natural languages such as Japanese and English by computer. This lab works on the classification of sentences and documents based on statistical language models, the estimation of similarity between sentences and between documents using deep learning, and the analysis of olfactory information using models similar to statistical language models.
*Illustrative imageClassification of Sentences and Documents and Estimation of Similarity
The lab studies how to identify and classify the classes of sentences and documents based on parameter estimation of statistical language models. It also studies how to estimate the similarity between sentences and between documents using deep learning.
*Illustrative imageAnalysis of Odor Information
Using images of activity patterns in the olfactory bulb of rats exposed to various substances, the lab works on identifying the features of an odor and the parts of the olfactory bulb that fire when detecting it. The lab also studies how to separate odor traces from measurement data of multi-channel odor sensors and visualize them.
