    Project has to use a database with 32 participants and extracts features to classify into emotions. First it must be taken the EEG signal filtered by bands: (Alpha, Beta, Gamma, Theta, and Delta) using feature extraction methods (like, wavelets, STFT, chirplet transform, etc), then it is necessary to extract the power spectral density in alpha and beta waves. This is only for AF3, F3, AF4, F4 channels. Then compute arousal and valence using Arousal = (front beta power) / (front alpha power) Valence = (left beta power) / (left alpha power) – (right beta power)/(right alpha power) to classify the emotions

    Dear FreelancerI have the following Problem. I started with a list of companies and created two files, one containing the returns for the companies and the other one corporate informations. In a final step i now want to make a multiple linear regression of this two files. The problem is that by calculating and sorting out the data, the one data string is approximatly 2100 observations and the other one 2500 even though i started with the same amount of information (companies). So somewhere in my code there must be a fault/ this code is not working for this data. I can think as a possilbe problem that i use the unique function once which might leeds to problems but im not sure where the fault is. If someone finds the problem in the code i would be able to pay up to 30 dollars. I don&quot;t think its a big deal if you are good in matlab.For further discussion please contact me. Also for the files. Thanks

    I have a set of 14 nonlinear equations to solve. I used lsqnonlin to solve them but I am failing in making it converge. This can be attributed to the large difference in value among the 14 unknowns. The solution can range from 1e-10 to 1 across the 14 parameters. I tried all tricks I know to overcome this problem but failed. You are free to use a different solver, write your own solver or normalize the equations in the way you like. The main code is a bit ling but you shouldn&quot;t care about it. All what you need to care about is the 14 equations at the end of the TRIAL_7 code and the caller subroutine for solving the equations. I attached also an excel sheet you approximate values of what some of 14 unknowns should be. These are just approximates of the solution. We can try solving the provided example and if we succeeded then we can try different examples to make sure that the code works. Please check the codes and try playing around with it before bidding. I will happy to provide any extra details and clarifications once needed.

    Goal:The goal of the project is to solve a PDE using Matlab. The main equation is presented in the &quot;pde_post_notes.pdf&quot;, equation (1). The numerical procedure of solving this problem should follow the details in Appendix D in &quot;Munk_Portfolio.pdf&quot;, page 37. The simulation of c_hat and pi should be plot which is a replication of the figure in &quot;pde_post_notes.pdf&quot;.A Skype training after deliver should be considered if we ask for.Milestones and % payment:1. Solve for function F using Matlab following the methodology in Appendix D, &quot;Munk_Portfolio.pdf&quot;. Check with reduced-form solution (section 3.1 in &quot;pde_post_notes.pdf&quot;) when rho_yS==1. (10%)2. Change value of rho_yS==0, and solve for function F, c_hat and pi again in Matlab. Simulate variables and provide the graph of those three series which is a replication of the figure in the notes. (10%)3. Deliver all the source file and Matlab code with sufficient explanation or comments. (70%)4. Training (10%)We have a time constraint on this project. The program is preferred to be finished within 3 days.

    I need a software, Windows and Mac(desirable) platform, to recognize pre registered people in jpeg high resolution pictures.The software just have to recognize only registered people ignoring all others.All the pictures will have very good quality, colors and resolution and if the system recognize one or more people, the informations will be write in a database or in the picture metadata (XMP Technology).The user interface should be like the Picasa facial recognition feature (annexed picture). Picasa is so close for my needs, but I don´t use it because it tries to recognize everybody and I just want recognize registered people.The minimum recognition accuracy acceptable is 85% because all the pictures have very good resolution.When the software are in doubt between two or more registered people, it will show for the operator choose the correct one.It´s indispensable the job with the source code and documentation for future integration with another software that I&quot;m developing.
