Article / Code / Data

This study introduces a novel, entirely artificially generated benchmarking dataset tailored for speech recognition, representing a core challenge in the field of tiny deep learning. SpokeN-100 consists of spoken numbers from 0 to 99 spoken by 32 different speakers in four different languages, namely English, Mandarin, German and French, resulting in 12,800 audio samples.

Neubig, L., Kist, A.M. (2023). Dataset Pruning using Evolutionary Optimization. Bildverarbeitung für die Medizin 2023.
Article

The right number of data points to solve an image processing task is crucial. To analyze how many data points in a dataset are important and unique enough to support the learning process of a neural network, we used an evolutionary approach in constrained (fixed dataset size) and an unconstrained mode (flexible dataset size).

Article

Is Batch Normalization always the best normalization method for a medical image segmentation task. We analyzed the influence of normalization methods in a U-Net layer wise in a systematic study using evolutionary optimization ad compared it to state-of-the-art models.

Groh, R. & Kist, A. M. (2023). End-to-end evolutionary neural architecture search for microcontroller units. IEEE COINS.
Article

Here, we introduce our end-to-end evolutionary NAS (EvoNAS) for microcontroller units that optimize both, pre-processing and neural network architectures. Each neural network architecture is assessed using the multi-objective accuracy, memory footprint, inference time, and energy consumption, to derive a common performance measure to be maximized. To ensure immediate use of all potential solutions on the microcontroller environment, we create a software-hardware chain in which each neural network is deployed to measure the inference time and power consumption directly.

Article

Our brain works with fuzzy and low-precision logic. In this study, we investigate how mixed-precision techniques have an effect of the training and inference efficiency of encoder-decoder deep neural networks in a biomedical image segmentation task.

Article / Code

Detecting the glottal midline accurately is crucial to assess quantitative parameters related to the symmetrical oscillation of the vocal folds. Here, we show how to use engineered neural networks to allow accurate midline detection simultaneously with glottal area segmentation.

Article / Code / Data

In this paper, we show by mining an encoder-decoder deep neural network that a single latent channel image is sufficient for glottis segmentation. Further, we describe the function of the latent channel and how this affects downstream glottis segmentation.

Article / Code

Airway symptom detection is crucial for monitoring chronic airway-related diseases. In this work, René is showing how data from neck surface accelerometers can be analyzed using a deep neural network in a computational constrained environment. He uses evolutionary neural architecture search to find an accurate, yet fast and deployable deep neural network for wearables.

Article

Swallowing disorders are commonly examined using videofluoroscopy swallowing studies (VFSS). To comprehensively evaluate the swallowing process, a typical VFSS contains different patient orientations. Here, we show a systematic architectural scaling approach and found that an efficient ResNet18 variant is sufficient to classify a full VFSS recording of about 1800 frames in less than 14 s on conventional CPUs.

Article / Code / Docs / Award

Commercially available systems for laryngeal high-speed videoendoscopy have not been further developed lately, are closed-source, and have only very limited analysis capacities. With OpenHSV, we provide a novel, award-winning, open hard- and software platform with DNN-powered online analysis.

Structured light endoscopy is a 3D-imaging method. However, the assignment of a projected laser grid to its reference is still tricky. We propose a Deep Learning-based image registration approach that achieves 91% accuracy on an ex vivo dataset.

Article

Deep neural networks are changing the way of biomedical diagnosis. For image segmentation, they can be very large and slow, especially on CPUs. In our recent studywe show that we can improve the glottis segmentation inference speed >79x fold by optimizing a popular biomedical segmentation network (U-Net) and porting it to the inexpensive EdgeTPU Hardware Accelerator.

Kist, A. M., Zilker, J., Gómez, P., Schützenberger, A., & Döllinger, M. (2020). Rethinking glottal midline detection. Scientific reports10(1), 1-15.
Article / Code

Symmetry is important in vocal fold motion. The identification of the glottal midline is crucial to deriving symmetry from the glottal area. Here, we evaluate different approaches to determine the glottal midline and suggest a multi-task architecture, GlottisNet, that predicts both simultaneously, glottis segmentation and glottal midline.

Article

Larval zebrafish swim when they perceive a whole-field moving stimulus. However, the underlying features that drive optomotor swimming remain elusive. Here, we show that larval zebrafish are predominantly driven by local light-dark transitions.
