I need someone to review and optimise an existing training model for an ensemble binary classifier in python. The classifier is for a lending app, with the outcome variables being ‘paid’ or ‘default’. The data is provided in a pre-processed format, in two files: 1. A flat file with one row for each item in the training set and c.40 variables 2. A short time series of a single variable A description will be provided for all variables. Also provided is the existing python code of the training model. It is a basic ensemble model combining some rudimentary out-of-the-box python machine learning algorithms. Key performance metrics will be the AUC, Precision, and Recall. Elements that will be required: • Improving performance of model • Feature selection to ensure generalisation/robustness • Cross-validation • Better hyper-parameter tuning • Model sensitivity testing • Determining appropriate weights for the ensemble Please let me know what is your bid for this work, and how long you think it will take. The process of work, and the milestone payments, will follow this order: 1. Review of existing model and short description of plans for work. (10%) 2. Progress report at half-way (40%) 3. Final output. (50%) The dataset and training model files will be provided once the project has been awarded.

Hi, My name is Sam Holden. I am a machine learning engineer with several years of industry experience. More importantly for your purposes: 1. I have the maths background to understand what the hyper-parameters do in the various algorithms you are likely to have used. 2. I can implement cv and sensitivity analysis work using a bayesian framework/looking at the distributional assumptions you have made. 3. I can assess whether increases in accuracy you are seeing are worth the risk to generalization that come with an ensemble approach (the distributions that come with human activity often change over time, which is why you often see less complex modeling in industry). Life, unfortunately, is rarely as simple as a Kaggle competition. With all this said, I am very confident that I can complete the list of objectives you have set in your description (assuming sensitivity is possible for the models you have chosen). I also have the experience to offer alternatives when I think they may help. I would like to discuss your project further at your convenience. Kind regards, Sam

I have experience in machine learning, deep learning and computer vision projects. Proposal: 1) Reviewing of existing ensemble/training model (provided by you), and check the possibility of adding or removing models from ensemble. 2) Explore the possibility of creating new variables from time series variable 3) Feature selection (Eg: SHAP values can be used for feature selection in case of tree models) 4) Tuning the hyper-parameters of individual models 5) Model sensitivity testing 6) Determining appropriate weights for ensemble models (Bayes optimization can be used for determining weights) What is the size of data set? please let us know.
