Breast Cancer Diagnosis and Segmentation (Mijung Kim)
Mammogram image
Normal
Benign
Malignant
1) Classify an input image as either normal (no lesion), benign, or malignant
2) Upon classification as either benignor malignant, segment the lesion
Upon classification asnormal, no segmentationis used
The red part of the heatmap below shows wherethe lesion is located
Targeted participation in the Digital Mammography DREAM challenge

Prediction of Drug-Target Interaction (Mijung Kim)
PCBA-2326
Target enzyme CID 2827036
Target enzyme CID 1014390
Target enzyme CID 332939
. . .
1) Feed a new or an existing drugcompound into a neural network
2) The output of the neural network showswhich target interacts with the drug compound
On hold, due to a lack of data and expert knowledge

Sleep Apnea Detection (Mijung Kim)
Normal Apnea Normal
1) Feature extraction fromraw data – synchronizedpolysomnography (PSG) data: EEG, EOG, EMG, …
2) Feed features into a neural network forclassification purposes
3) The result is one ofthree classes – normal,apnea, or hypopnea
Under discussion with imec (www2.imec.be)

Splice Site Detection (Jasper Zuallaert)
… ACCAGGTAAGCGCATCCGACATCTCTCAACGAGTCGAC …
In cooperation with VIB (www.vib.be)
1) Search for patterns using convolutional windows
2) Combine patterns found to classify a candidate splice site as a true splice site or as a pseudo splice site
… ACCAGGTAAGCGCATCCGACATCTCTCAACGAGTCGAC …
True splice site
