Jamisola, Rodrigo S.
This book is a collection of all laboratory exercises for the course Artificial
Intelligence and Machine Learning for Engineers, a fifth-year level course for the program Bachelor of Engineer in Mechatronics and Industrial Instrumentation in Botswana International University of Science and Technology, Palapye, Botswana. The exercises were designed to enhance the understanding of the students to complement the topics discussed in the lectures. Most of the exercises require the students to perform manual
computations in order to enhance their theoretical understanding. This book includes the course syllabus as well as lecture slides for the entire semester. Interested students can attend virtual class discussions uploaded on YouTube via the channel of the author.

The dynamical behavior of pulse and traveling hole in a one-dimensional system
depending on the boundary conditions, obeying the complex Ginzburg-Landau
(CGL) equation, is studied numerically using parameters near a subcritical bifurca-
tion. In a spatially extended system, the criterion of Benjamin-Feir-Newell (BFN)
instability near the weakly inverted bifurcation is established, and many types of
regimes such as laminar regime, spatiotemporal regime, defect turbulence regimes,
and so on are observed. In finite system by using the homogeneous boundary
conditions, two types of regimes are detected mainly the convective and the
absolute instability. The convectively unstable regime appears below the threshold
of the parameter control, and beyond, the absolute regime is observed. Controlling
such regimes remains a great challenge; many methods such as the nonlinear
diffusion parameter control are used. The unstable traveling hole in the one-
dimensional cubic-quintic CGL equation may be effectively stabilized in the chaotic
regime. In order to stabilize defect turbulence regimes, we use the global time-delay
auto-synchronization control; we also use another method of control which consists
in modifying the nonlinear diffusion term. Finally, we control the unstable regimes
by adding the nonlinear gradient term to the system. We then notice that the
chaotic system becomes stable under strong nonlinearity.
