*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

We are looking to have a computer vision expert create a very specific .NET/Mono compatible library for us to use in an application we are creating. This will include (either entirely from scratch or using the help of open source, commercial friendly libraries): - Implementing a very performant rotation/scale invariant template matching routine, and training routine for it. - Implementing geometry detection (size, location, rotation) of circles and rectangles. - Implementing camera calibration routines to calibrate cameras based on known grids or shapes, and applying that calibration to the other routines. - Various other routines as you determine necessary to meet the requirements outlined in the attached document. If these tasks are things you feel you can excel at then please see the attached document which outlines the deliverables for this project, as well as the acceptable languages and required platforms. Please DO NOT bid on this project if you have not read the attached document. Please have a portfolio or references to show your experience with customized computer vision routines and algorithms. You will have direct and prompt answers to any questions from the developer of both the application that will use this library and the machine that it is being used for. An extremely detailed document of use cases for each routine can also be provided once hired. Unlimited sample images can be provided to order from the machine this will be used with. We would like to find someone who can pursue this aggressively, with an ideal deadline of 30 days, but more would be considered for the right candidate. PLEASE NOTE: Bids above and below the budget given will still be seriously considered based on experience, ability to dedicate a large amount of time, communication skills, etc.

We have several applications for data science and machine learning in our project. Were looking for someone who is excellent with algorithm selection and preferrably willing to roll up their sleeves and write some python or golang to prove their solution. We have a test You must pass to join the team. Must be able to select and explain your selection of an algorithm for our test. Lots of exciting work in this project.

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.

I would like to use Microsoft Computational Network Toolkit (CNTK) for one my project. The CNTK is still under development so the documentation is succinct. I would need someone to go through the documentation and identify the simplest way for me to train a model on my own images and how to integrate CNTK in my project. Ideally it should work with VS2015 but the documentation mention that only VS2013 is supported for now, maybe a quick fix is possible. Some links: https://github.com/Microsoft/CNTK https://github.com/Microsoft/CNTK/issues/33
