Conclusion

Conclusion

  • LSS is a starting unit with 2 years existence built on a background extending to 11 years of several members.

  • Two balanced application areas:

    • System Identification and Analysis;

    • Pattern recognition and synthesis in Speech Processing.

  • Promising results (some of them pioneering) increased with the ending of PhD works.

  • Rapidly growing scientific productivity because of

    • Moderately available energy and funds from past years

    • High quality human resources (remark: our funds are ending...).
