Projects currently in progress:

NeurAdapt”, has indirectly received funding from the European Union’s Horizon 2020 research and innovation action programme, via the AI4Media Open Call #1 issued and executed under the AI4Media project (Grant Agreement no. 951911). Learn more at  ai4media.eu

Description: The goal of NeurAdapt project is to explore a new path in the design of deep Convolutional Neural Networks (CNNs), which could enable a new family of more efficient and adaptive models for any application that rely on the predictive capabilities of deep learning. Inspired by recent advances in the field of biological Interneurons that highlight the importance of inhibition and random connectivity to the encoding efficiency of neuronal circuits, we aim to investigate the mechanisms that could impart similar qualities to artificial CNNs.

Established techniques such as Channel Gating, Channel Attention and calibrated dropout, each proposed independently and with different objectives, can offer tools to formulate a novel building block for CNN models that expands the functional diversity of the standard convolutional layer. By formulating a differentiable convolutional operator with additional mechanisms for competitive inhibition/excitation and stochastic activation with tunable probability, we pursue the hypothesis that the optimization of the learning tasks will drive the model to create modes that are information-rich, in a process like the one observed in biological neural networks.

Furthermore, the stochastic nature of neuronal activity if appropriately modelled and augmented with sparsity-inducing mechanisms, has the potential to enable the training of models with parametrized levels of sparsity, offering the capacity to control inference/complexity tradeoff on-the-fly, without any need for additional finetuning. Achieving a functionality like this can impart new capabilities to information processing systems which are based on CNNs. Inference with adjustable level of thoroughness/speed can enable applications such as rapid content search in large media databases, energy-aware decision-making etc.

The main outcome of the proposed project will be a new methodology for designing efficient deep CNN architectures regardless of the specific task and target domain. Furthermore, NeurAdapt aims to create new knowledge regarding the dynamic behavior of the excitation-inhibition mechanisms in feed-forward DNNs, their capabilities for further development and the respective limitations.

Zero-defect wELDing for e-mobility”, funded under EIT Manufacturing, grant agreements no. 21122 (year-2021) and no. 22204 (year-2022). Learn more at  zeld-e.eu

Description: ZELD-e aims to reconfigure and update the existing monitoring and control schema of the welding processes involved in tab-to-tab (T2T) and tab-to-busbar (T2B) joining of battery packs (BP) used in EVs, in order to increase the joint quality, reduce and even eliminate defective parts, optimize equipment’s productivity, energy consumption and minimize development time and time-to-market. The proposed solution/system is based upon a multilevel approach, including the enhancement of the sensorial configurations, the data acquisition (DAQ), and control functionalities located at the edge (shop floor), backed up by a centralized web-based platform with visualization, Quality Assessment (QA) and data processing/analysis capabilities paired with a long-term control optimization schema.

Our Role: Vision-based monitoring and control schema for QA of laser welding processes in battery packs.

Artificial Intelligence Applied to Space”, funded under H2020, grant agreement no. 776262. Learn more at  aida-space.eu/

Description: AIDA brings a transformational innovation to the analysis of heliophysics data in four steps.
First, AIDA will develop a new open source software called AIDApy written in Python (a free language) and capable of collecting, combining and correlating data from different space missions. AIDApy wants to replace mission-specific tools written for costly languages (such as IDL) that exclude many scientists, students and amateur space enthusiasts from exploring the data, with a much-needed single platform where methods are shared and continuously improved by the whole community.

Second, AIDA will introduce modern data assimilation, statistical methods and machine learning (ML) to heliophysics data processing. Unlike traditional methods based on human expertise, these methods rely on statistics and information theory to extract features that are hidden in the data.

Third, AIDA will combine real data from space missions with synthetic data from simulations developing a virtual satellite component for AIDApy. This feature will be demonstrated in the comparison with existing mission data and in the planning of new missions (e.g. ESA’s THOR).

Fourth, AIDA will deploy in AIDApy methods of Artificial Intelligence (AI) to analyse data flows from heliophysics missions.
This task requires bridging together competences in computer science and in heliophysics and pushes well beyond the current state of the art in space data analysis, connecting space researchers with AI, one of the fastest growing trends in modern science and industrial development.
AIDA will use the new AIDApy in selecting key heliophysics problems to produce a database (AIDAdb) of new high-level data products that include catalogs of features and events detected by ML and AI algorithms. Moreover, many of the AI methods developed in AIDA will themselves represent higher-level data products, for instance in the form of trained neural networks that can be stored and reused as a database of coefficients.

Our Role: Development of Python-based AI framework (incl. AI model optimizations) for analysing data flows in space weather data.

A Hybrid (Additive and Subtractive) Processing Robotic system”, co-financed by the EU and National funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH – CREATE – INNOVATE, project no. Τ2ΕΔΚ-03896. Learn more at  hybridr-project.eu

Description: Additive Manufacturing (AM) technologies have shown a rapid development over the last decade. Metal AM is now adopted in numerous industries, such as naval, energy, aerospace and automotive. AM provides a very flexible solution for processing of exotic materials (Ni-alloys, Titanium, etc.) and enables repair of components that would not be possible with conventional processing. However, AM cannot provide on its own parts that will meet the requirements of the aforementioned industries. To this end, subtractive processes have to be combined in a hybrid solution, in order to achieve the required quality for the part, in terms of dimensional accuracy and surface finish.

HybridR is proposing an innovative robotic-based platform, which incorporates Laser Metal Deposition, milling and grinding as enabling technologies. The use of a robot as a base structure will provide a very high flexibility to the system and will showcase that robots can have a very high potential in the manufacturing industry.

Our Role: Vision-based monitoring and quality assessment in Laser Metal Deposition, Milling and Grinding (i.e. melt pool monitoring and parts’ geometry) on a robotic-based Additive manufacturing platform.

Development of an innovative and flexible system of terrestrial meteorological, atmospheric and solar measurements with the synergy of physical models and computer vision and deep learning techniques”, co-financed by the EU and National funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH – CREATE – INNOVATE, project no. Τ2ΕΔΚ-00681. Learn more at  deepsky-project.com

Description: The main goal of the DeepSky project is to develop an innovative and flexible ground-based measurement system designed to address the end-use needs of end-users in the meteorological, atmospheric and solar energy communities. DeepSky will build on the high scientific potential and technological advances in the field of instrumentation based on the analysis of digital images of the celestial dome, the modeling of the propagation of solar / thermal radiation and the contribution of computational vision and deep learning methods.

Our Role: Computer vision and deep learning techniques for the analysis of digital all-sky images (cloud types and cloud coverage, cloud prediction etc.).

Analysis of sign language on mobile devices with focus on health services”, co-financed by the EU and National funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH – CREATE – INNOVATE, project no. Τ1ΕΔΚ-01299. Learn more at  xanthippi.ceid.upatras.gr/HealthSign

Description: Sign Languages (SLs) are the main means of communication for deaf people. The access to SL is essential for the fulfillment of basic Human Rights, however there is a shortage of interpreters, which undermines these rights and often endangers the lives of the deaf, especially in cases of emergency or serious health incidents.

HealthSign proposes to develop an application for the automated interpretation of the Greek Sign Language (GSL) over internet with focus on the health services, which are the most common reason to seek for an interpreter. The high demand for interpreters is often not met or requires long waiting. Furthermore, the availability of interpreters facilitates the integration of the deaf community.

Vision is probably the only sensor modality that could be of practical use because (a) only vision can capture manual and non-manual cues, which provide essential information for SLR, (b) camera-equipped hand-held devices with powerful processors are a commodity nowadays and (c) recent advances in computer vision and machine learning render mainstream visual SLR a realistic option.
