Explanation about given Data: I have data with 2000 Traces and 980 samples in each trace. All the traces are same except at certain locations. These locations can be found by increasing N and detecting brighter parts of the given plot in Test1.m. After running the m-file Test2.m, we came to know that the difference signal between certain traces is higher than the difference between other traces in the same range. Say, for-example, if we take the traces from 1(init) to 100(N) with transition trace of 5 (sub_N), then plotting the difference trace of tr5-tr1, tr10-tr6, tr15-tr11…tr100-tr96 might gives rise to an average of lower trace-difference than plotting traces from 1(init) to 70 (N) with transition trace of 7 (sub_N). Moreover, there are results that might get changed if the initial value is started from any other value than 1. For example, for init=3, and N=100 with transition trace of 5 gives rise to Difference_Trace with tr8-tr3, tr13-tr9,…tr99-tr95 and its value might be changed than that of init=1. Hence in summary it is possible that by changing init, sub_N and N values, we get different possibilities of our final result. It should be noted that the Difference_Trace between 90 and 230m keep changing with change in the mentioned three parameters. However, the Difference-Trace between 1600m and 1700m do not change significantly or almost remains constant through-out. Task For Freelancer: I need the expert with quite a sound statistical background who have worked on Neural networks, machine learning, and other relevant algorithm designs who should provide me the following results: 1) Classify the results in two classes such that the variable Difference_Trace (between 90 and 230m) is classified as different class than the constant Difference_Trace (between 1600 and 1700) such that the distance information is never lost. For-example, a Difference_Trace should be classified such that the user should know the ranges for variable Difference_Trace which is between 90m and 230m in our case and it should provide range information for the constant Difference_Trace which is between 1600m and 1700m in current data case. The code should be generalized for any kind of Difference_Trace as the location and range of variable and constant Difference_Traces may vary. The variable and constant in current data is located at single positions. They might have multiple positions in case of other data. It means some unsupervised learning technique should be applied as the perturbation location might be unknown. The instructor will check it with other data-set, so please be careful. (Kindly specify the algorithm before starting the project. If someone can apply more than one algorithms for the sake of comparing the results then please specify all the applied algorithms) 2) The variable Difference_Trace should be further classified. There are some features around 155~165m location which are different than rest of Difference_Trace range. I need to classify it from the rest of variable Difference_Trace. It means the variable Difference_Trace should be further classified in other two classes. This part code may not be generalized as this section of code will not be applied to other data sets. Note: Preferred language is Matlab, but if the routine is written in Python then it is ok. The code should be well commented so that a lay man can understand the code easily. It is semester project for a course so please don’t disseminate the code with other students within a month. There are two tasks, if at the end of day the freelancer is able to provide solution for only one task, then half price of the project amount will be provided. Milestone payment will be released within 03 days of delivery of the task as checking the provided code with other data may take time.

What experience do you have that is relevant to this project? I do machine learning stuff and also statistical analysis using those algos for various regression and classification problems, on a regular basis. Proposal: Hello!!!!! So, here is what you can do. You don;t have to necessarily apply any sophisticated unsupervised learning here. First, create two mat files with the two type of differences you've mentioned (actually you've written such a long story that I lost you midway, perhaps you could have explained them via Skype) and plot them on a 2D plot and just have a look. I think you can see two separate clusters forming for the two type of differences. x-axis: samples, y-axis diff-2, diff-1 in same plot. If it is possible for you to discern among the two groups visually, you can apply then, k-means with k=2 to find the centroid of the two groups. Then, any new sample can be classified based on the absolute difference from the centroids. Thanks!!
