Hello, I am looking for support in building and updating Machine Learning models using Azure Machine Learning. The initial task is the following: Building a recommendation engine, the data is already available the model we want to use is already chosen, but need assistant with manipulating and reducing the data through feature hashing, principal component analysis etc. I am hoping to establish a relationship with someone who has strong Machine Learning and statistical experience and can assist in evaluations of multiple clustering and predictive models. Thanks!

The company helps publishers monetize their digital assets using advertising The company makes money by taking advertising from multiple third party advertising networks and agencies, and through a proprietary process, dynamically places it within a publisher’s digital asset. From there, the company collects the revenue from the networks and agencies, takes it commission, then remits the remainder of the funds to the publisher. Advertising networks and agencies (advertising partners) use different methodologies to price the advertising space they are buying within a publisher’s digital asset. Some advertising partners use a straight CPM (cost per 1000 impressions) method, others use a PPC (price per click) method, while very few use a CPA (cost per acquisition) method. In addition to the disparate pricing methods, advertising partners also use disparate placement methods such as RTB (real time bidding) with the acceptance of a price floor, RTB with no pricing floor, a black box of only knowing what the PPC is after click occurs. Given these pricing and placement differences, the company needs to develop a yield maximization algorithm where it can maximize the revenue from each ad unit, in a particular digital asset. Actual final coding will be conducted by our in-house engineers. Attached is related research.

We are looking for a seasoned professional on Machine Learning, Experience with the Spanish Language on a modeling level (If not with previous experience with bots on Spanish, experience on creating conversational bots in English, will be fine), and Facebook Bots. The main idea is solve in an automated way the easiest (and more common questions) regarding client services, in order to speed up support questions, we have a big corpus of samples answered by human operators on the range of a full year. We are open to a software platform (The selected platform/tools/libraries must be free/opensource) or worked from scratch, If need licences or webservices must document their cost and relevancy to the project. All the interactions to the client must be done with Facebook Messenger (This part is not the most important, the most important part of this project is working on the questions solving). If the pricing is too low, we can talk to ensure both us, can have the maximum benefit (for me a productive, freelancer and a quality work, and a proper monetary reward for you).
