I have a clean dataset of around 200,000 observations over the last 15 years of certain financial events, with around around 10 features that can be used to predict returns. I have attached an ipython notebook with my work so far, and I'm looking for an expert to help me take this further. Note that because this is event data, instead of the normal random split of the dataset into training / testing, we need to only use historical data in the training set. If this works out well, there are many other similar datasets that I wish to analyze, and this will be a long term relationship with challenging, interesting and well compensated work. Skills: Machine learning (PCA, ANN, SVM, feature scaling, parameter optimization, ensemble algorithms, algorithm evaluation techniques), time series analysis, data visualization Packages: Python data analysis (ipython notebook, pandas, sklearn, seaborn / matplotlib) Must have strong verbal and written communication in English.

YOU AND/OR YOUR COMPANY ARE… 1. experienced in advanced metrics: http://bit.ly/1PYLxei 2. experienced in machine learning and predictive sports betting analytics, ala: https://www.swishanalytics.com/ WE need an advisor/designer who can… A. look at the data we are currently scraping, and offer suggestions on how the data might be analyzed within our system to offer overviews and predictions similar in fashion to points 1 and 2 from above. B. assist in the creation of algorithms that our programmers will implement into our system. C. independently evaluate and test that the formulas and algorithms you have suggested and created for us, have successfully been implemented by our programmers into our system. D. be prepared to continue indefinitely with us in a cycle from A to C. WE DON’T NEED… -individuals and companies that can’t keep to a budget, or feel that deadlines are optional. We expect that the person(s) who are awarded this project will give clear and solid estimations on hours needed for completion of work, and will meet their deadlines without fail. -individuals and companies that don’t maintain regular and frequent contact with us. Failure to respond to a request for an update or other information within 24-48 hours, is grounds for termination from this project. -individuals and companies that want hours and weeks, “to run your data through our system, on our servers, to run tests to determine what might be the best possible outcome.” NO! You will only be serving in an advisory role as to what tests will be run on OUR system alone. We are absolutely open to any and all suggestions from you on how we might proceed, but we will not pay for testing periods outside of our system. IN SHORT… Look at our system and data; advise on how to implement advanced metrics and predictive analytics into the system; create the algorithms; check that the algorithms were correctly put in; make new suggestions on improvements and changes.

*Background:* Perhaps I already have it, but I simply do not know how to make sense of trained model results in R to make useful predictions out of R on new data. I just don't have statistics background, but I have programming background. So I think I just need someone who knows enough statistics and enough about R to show me how to make sense of training results in my R script. *Request:* I need the attached R script modified to accomplish the following: *(1)* Extract the result/formula, (formula values) of the classification models for each group/class, (-2,0,2) after my attached R script completes Stepwise LDA, QDA and Logistic Regression. I want formula values, not the formula code so I can make predictions out of R on new data. *(2)* Extract the formula for the decision bounds that separates the groups/classes, (-2,0,2) after my attached R script completes Stepwise LDA, QDA and Logistic Regression. I want formula decision bounds, not the decision bounds code so I can make predictions out of R on new data. Specifically, I want my R script, (see attached .zip in job posting) modified to give me the data necessary to do similar to what is seen in video in [Column D] and in [Cells F21:G25] and [Column E], but for after I run my R script for LDA, QDA and Logistic Regression. -- See video from *2:18 to 4:05* for [Column D] -- See video from *4:05 to 7:31* for [Cells F21:G25] -- See video from *7:32 to 8:28* for [Column E] https://www.youtube.com/watch?v=NaZ6Xuczs94 This screenshot might be a good example of the values I need extracted from LDA, QDA and Logistic Regression in R http://www.screencast.com/t/hmUHHvrRF7cV

Develop ensemble models using healthcare data in order to return predictions about health. This will include csv files (for example, electrocardiogram data for detecting heart health), and images (for example, mammogram images for detecting cancer). The successful freelancer will be very familiar with: 1. Creating and running ensemble/layered models (example: https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/14335/1st-place-winner-solution-gilberto-titericz-stanislav-semenov) 2. The following libraries (and hopefully more): - XGBoost - Fast and optimized GBM implementation. - Vowpal Wabbit - Very fast with lots of parameters and linear algorithms. - LibFM - Factorization Machines. - scikit-learn - Lots of functions and algorithms. - Lasagne - Very good and fast NN implementation (but unfortunately I don't have a GPU). - Matlab Neural Network Toolbox - Classic. - R GBM, randomForest and glm - Classic.
