7. Συµµετοχή σε ερευνητικά και αναπτυξιακά προγράµµατα 7.1. Ερευνητικό-Αναπτυξιακό πρόγραµµα 14DHMO1 "Νευρωνικά ∆ίκτυα" στα πλαίσια των Σχεδίων Περιφερειακής Ανάπτυξης του Α’ Κοινοτικού Πλαίσιου Στήριξης (1991-1994). Με την εργασία µου στα πλαίσια του προγράµµατος αυτού συνέβαλα ουσιαστικά στη δηµιουργία του Εργαστηρίου Νευρωνικών ∆ικτύων (ΕΝ∆) στο Ι.Π.Τ. του ΕΚΕΦΕ "∆ηµόκριτος". Οι δραστηριότητές µου στα πλαίσια του προγράµµατος "Νευρωνικά ∆ίκτυα" συνοψίζονται ως εξής:

• Συµµετοχή σε όλες τις φάσεις του προγράµµατος µε τη σχεδίαση και υλοποίηση πρωτότυπων νευρωνικών αλγορίθµων και εφαρµογών τους (ιδιαιτέρως στην επεξεργασία στοχαστικού σήµατος και ταυτοποίηση συστηµάτων) καθώς και µε την ανάπτυξη του κυρίου µέρους του απαιτούµενου λογισµικού προσοµοίωσης.

• ∆ιεύρυνση των αρχικών στόχων του προγράµµατος σε τοµείς όπως η επεξεργασία ιατρικών και δορυφορικών εικόνων που οδήγησε στην πλήρη απορρόφηση των κονδυλίων του προγράµµατος συνολικού ύψους 50.000.000 δρχ.

• Αξιοποίηση των αποτελεσµάτων του προγράµµατος µε τη συµµετοχή µου στην υποβολή σχετικών προτάσεων σε ερευνητικά προγράµµατα εθνικής και ανταγωνιστικής εµβέλειας.

• Συµµετοχή στην ανάπτυξη των εξής τελικών προϊόντων του προγράµµατος:

• Λογισµικό προσοµοίωσης αλγορίθµων εκπαίδευσης νευρωνικών δικτύων: Πρόκειται γιά ολοκληρωµένο περιβάλλον λογισµικού που περιλαµβάνει µία πλειάδα νευρωνικών αλγορίθµων.

• Εκτός από αλγορίθµους που αναπτύχθηκαν από άλλους ερευνητές - π.χ. αλγόριθµος αντίστροφης διάδοσης των σφαλµάτων (error back propagation) και παραλλαγές του

το περιβάλλον περιλαµβάνει πρωτότυπους αλγορίθµους των Καρρά και Περαντώνη που βασίζονται σε τεχνικές µη γραµµικού προγραµµατισµού (Algorithms for Learning Efficiently using Constrained Optimization Techniques - ALECO). Οι αλγόριθµοι αυτοί ενσωµατώνουν πληροφορίες γιά την

βελτίωση βασικών ιδιοτήτων της διαδικασίας εκµάθησης, ώστε να καταστούν τα νευρωνικά δίκτυα κατάλληλα γιά εφαρµογές σε πραγµατικά προβλήµατα πρακτικού ενδιαφέροντος όπως ανάλυση σηµάτων και εικόνων (ήδη έχουν εφαρµοστεί στην ανάλυση βιοιατρικών και δορυφορικών εικόνων). Εκτεταµένοι έλεγχοι και συγκρίσεις των αλγορίθµων που περιλαµβάνονται στο περιβάλλον λογισµικού πραγµατοποιήθηκαν στο δίκτυο SUN-sparcstation και στον υπερυπολογιστή CONVEX-3820, που κατέδειξαν την ανωτερότητα των αλγορίθµων ALECO σε µία σειρά προτύπων προβληµάτων.

• Λογισµικό οπτικής αναγνώρισης χαρακτήρων. Η ενσωµάτωση σε σύστηµα που αναπτύχθηκε στο ΕΝ∆ µίας σειράς µεθόδων οπτικής αναγνώρισης χαρακτήρων - µεταξύ των οποίων περιλαµβάνονται και νευρωνικοί ταξινοµητές τύπου ALECO - οδήγησε σε υψηλά ποσοστά αναγνώρισης τυπωµένου κειµένου που φτάνουν ώς 99.8%.

• Ψηφιακό Σύστηµα τεχνητής όρασης γιά την αναγνώριση γεωµετρικών αντικειµένων. Το σύστηµα αυτό χρησιµοποιεί µεθόδους εξαγωγής χαρακτηριστικών βασισµένες στις ροπές Zernike καθώς και νευρωνικούς ταξινοµητές και επιτρέπει την αναγνώριση δισδιάστατων σχηµάτων, ανεξάρτητα από τη θέση και τη γωνία περιστροφής τους. Επιπλέον, το λογισµικό αναγνώρισης αντικειµένων συνεργάζεται µε τον ροµποτικό βραχίονα του ΕΝ∆, γιά την καθοδήγηση της συσκευής εικονοληψίας κατά τέτοιο τρόπο, ώστε να γίνεται εφικτή η αναγνώριση και τρισδιάστατων αντικειµένων.

• Το σύστηµα αυτό έχει προφανείς εφαρµογές σε προβλήµατα pick and place αλλά σαφώς και σε άλλου είδους προβλήµατα αναγνώρισης µορφών, όπως αυτά που σχετίζονται µε τα γεωγραφικά συστήµατα πληροφοριών κλπ.

• Αποτέλεσµα της συµµετοχής µου στο πρόγραµµα είναι οι εργασίες 1.2-1.6, 2.4-2.14 και 3.1-3.3

7.2. Ερευνητικό πρόγραµµα CT-93-1292 "Ultrasonic Scanner-Quantitative Dynamic Imaging" στα πλαίσια του ανταγωνιστικού Ευρωπαϊκού προγράµµατος Biomedical and Health Research (BIomed I) (1994-1995). Το πρόγραµµα αυτό έληξε τον 12/95. Οι δραστηριότητές µου στα πλαίσιά του συνοψίζονται ως εξής:

• Ερευνητικές και αναπτυξιακές δραστηριότητες στις δύο φάσεις του προγράµµατος που είχε αναλάβει το ΕΝ∆ του ΙΠΤ.

• Σχεδιασµός αλγορίθµων και ανάπτυξη µέρους του απαιτούµενου λογισµικού γιά την επίτευξη των κατωτέρω στόχων:

• ∆υναµική κατάτµηση εικόνων υπερηχοκαρδιογραφηµάτων. Προσεγγιστική διαγράµµιση της θέσης του ενδοκαρδίου/επικαρδίου µε χρήση αλγορίθµων επεξεργασίας εικόνας και αριστοποίηση του προσδιορισµού της θέσης ενδοκαρδίου/επικαρδίου µε χρήση νευρωνικών δικτύων.

• Παρακολούθηση της κίνησης του ενδοκαρδίου και επικαρδίου µε βάση πληροφορίες γιά την θέση και ταχύτητα τµηµάτων τους από προηγούµενες εικόνες που παίρνονται κατά τη διάρκεια του κύκλου της καρδιάς. Η επίτευξη ακρίβειας στην παρακολούθηση δίνει τη δυνατότητα λήψης καθαρότερων εικόνων της καρδιακής χώρας.

Γιά την παρακολούθηση απαιτείται πρόβλεψη της κίνησης που επιτυγχάνεται µε χρήση νευρωνικών δικτύων (κυρίως των αλγορίθµων ALECO), φίλτρων στοχαστικού σήµατος Kalman καθώς και θεωρίας χρονοσειρών (Box-Jenkins ARMA modeling). Αποτέλεσµα της συµµετοχής µου στο πρόγραµµα είναι οι εργασίες 1.19, 2.15, 2.19 και 3.4. 7.3 Ανθρώπινο δίκτυο διάδοσης ΝΕΥΡΩΝ, στα πλαίσια των προγραµµάτων ανθρωπίνων δικτύων διάδοσης της Γενικής Γραµµατείας Ερευνας και Τεχνολογίας.

Το έργο αυτό επερατώθη (1/10/96-31/12/97) και η συµµετοχή µου σε αυτό είχε ως αντικείµενο την διεκπεραίωσή του µέσω της καθοδήγησης διπλωµατικών εργασιών που αποσκοπούσαν στην προσαρµογή υπάρχοντος λογισµικού για την σχεδίαση εκποµπών υπερήχων, µε ιδέες προερχόµενες από την περιοχή του µη καταστρεπτικού ελέγχου, στο περιβάλλον του ακουστικού πεδίου της καρδιάς.
