Parameter Tuning in SVM-Based Power Macro-Modeling
R – INESC-ID Lisboa –
We describe a methodology that uses of support vector machines
(SVMs) to determine simpler and better fit power macromodels of
functional units for high-level power estimation. The basic approach
is first to obtain the power consumption of the module for a large
number of points in the input signal space. Least-Squares SVMs are
then used to compute the best model to fit this set of points. We
have performed extensive experiments in order to determine the best
parameters for the kernels. Based on this analysis, we propose an
iterative method of improving the model by selectively adding new
support vectors and increasing the sharpness of the model. The
macromodels obtained confirm the excellent modelling capabilities of
the proposed kernel-based method, providing both excellent accuracy
on maximum error (close to 17%) and average (2% error), which
represents an improvement over the state-of-the-art. Furthermore, we
present an analysis of the dynamic range of power consumption for
the benchmarks circuits, which serves to confirm that the model is
able to accommodate circuits exhibiting a more skewed power

International Day of Women and Girls in Science: Inês Lynce at Pavilhão do Conhecimento
Inês Lynce — President of the Board of Directors of INESC-ID, Automated Reasoning and Software Reliability (ARSR) researcher, CMU Portugal National Co-Director and Full Professor at Instituto Superior Técnico — will participate in the Ciência Viva celebrations for the 2023 International Day of Women and Girls in Science (IDWGIS) on 11 February.
Inês Lynce is one of the invited speakers of the Roundtable “Pergunta-me o que é ser cientista” (Ask me what it means to be a scientist; 15:00-16:30 at Auditório José Mariano Gago, Pavilhão do Conhecimento), where female researchers and university students from different areas of science (engineering, information technology, physics and mathematics) will speak about what it means to be a “woman in science” in each of their fields.
The IDWGIS at Pavilhão do Conhecimento will be entirely dedicated to promoting activities to encourage and promote access for all girls and women to training and education in the field of science.
Here’s the full agenda.
