PRIVACY POLICY

Personal information is collected from you and about you when you use the Cough against TB application (henceforth called the App). We are committed to protecting the security of this information and safeguarding your privacy. This privacy policy sets out the details of the personal information collected, the manner in which it is collected, by whom as well as the purposes for which it is used. At registration you are requested to accept the terms of this Privacy Policy and your use of the App signifies your continued acceptance thereof. This Privacy Policy may be revised from time to time and you will be notified of all such changes. In order to use the App, you will be required to consent to the terms of the Privacy Policy.

Intended Users

This app is intended to be used by the general public of India between the age groups of 18 years to 100 years, who are not availing any tuberculosis treatment.

Context for Use

In order to get the inference from the app about the likelihood of pulmonary tuberculosis, a compatible smartphone with a working internal microphone is required. The audio (cough and background sounds) need to be recorded in well ventilated, noise free environment preferably at home.

1. Information Collected and Manner of Collection

(a) When you register on the App, the following information is collected from you and stored securely on a cloud operated and managed by Wadhwani AI – (i) full name; (ii) date of birth; and (iii) gender. In order to receive the inference/result of your or other individual’s likelihood of pulmonary tuberculosis as per the current AI model used in the App, the relevant vital statistics, symptomatic data, cough (audio) and background (audio) data is requested. This information will be stored on the cloud and a unique digital id (UUID) will be assigned to your information. The UUID will thereafter be used to identify you in all subsequent App related transactions and will be associated with any data or information uploaded from the App to the cloud. At registration, your location details are also captured and uploaded to the cloud.

(b) Each time you complete a self-assessment test, the App will collect your result and location data along with the data you shared. This is securely stored on your device and will be uploaded to the cloud with your consent.

(c) The App shall facilitate the verification of the user’s identity through mobile number based OTP verification.

(d) The App shall facilitate the storage of and the medical diagnostic tests done by/ for the individual. The following information is collected:

  • Chest X-Ray
  • CBNAAT
  • TRUENAT
  • Smear Microscopy

2. Use of Information

  1. The personal information collected from you at the time of registration under Clause 1 (a, b, c) above, will be stored on the cloud and only be used by the Government of India in anonymised, aggregated datasets for the purpose of generating reports, heat maps and other statistical visualisations for the purpose of the management of tuberculosis in the country or to provide you general notifications pertaining to tuberculosis as may be required. Your UUID will only be correlated with your personal information in order to communicate to you the probability that you have a likelihood of contracting tuberculosis and/ or to provide persons carrying out medical and administrative interventions necessary in relation to tuberculosis, the information they might need about you in order to carry out such interventions.
  2. The information collected from any other user’s mobile device and uploaded and stored on the cloud in accordance with Clause 1 (b) will be used to calculate your probability of having been infected with tuberculosis.
  3. The information collected under Clause 1 (a) will be used by the Government of India to evaluate, based on the self-assessment tests and the GPS locations from where they are being uploaded, whether a disease cluster is developing at any geographic location.
  4. The information collected under Clause 1 will not be used for any purpose other than those mentioned in this Clause 2.

3. Retention

(a) All personal information collected from you under Clause 1 (a) at the time of registration will be retained for as long as your account remains in existence and if any medical or administrative interventions have been commenced under Clause 2, subject to Clause 3 (b) below, for such period thereafter as is required for such interventions to be completed.

(b) All personal information collected under Clauses 1 (a), 1 (b),and 1 (c) will be retained on the mobile device for an indefinite period from the date of collection after which, if it has not already been uploaded to the cloud, will be purged from the App. All information collected under Clauses 1 (b), 1 (c), 1 (d) and 1 (e) and uploaded to the cloud will, to the extent that such information relates to people who have not tested positive for tuberculosis, will be purged from the cloud after an indefinite period after being uploaded. All information collected under Clauses 1 (b), 1 (c), 1 (d) and 1 (e) of persons who have tested positive for tuberculosis will be purged from the cloud after an indefinite period such persons have been declared cured of tuberculosis.

(c) Nothing set out herein shall apply to the anonymised, aggregated datasets generated by the personal data of registered users of the App or any reports, heat maps or other visualisation created using such datasets. Nothing set out herein shall apply to medical reports, diagnoses or other medical information generated by medical professionals in the course of treatment.

ML Engineer

ROLES AND RESPONSIBILITIES

An ML Engineer at Wadhwani AI will be responsible for building robust machine learning solutions to problems of societal importance; usually under the guidance of senior ML scientists, and in collaboration with dedicated software engineers. To our partners, a Wadhwani AI solution is generally a decision making tool that requires some piece of data to engage. It will be your responsibility to ensure that the information provided using that piece of data is sound. This not only requires robust learned models, but pipelines over which those models can be built, tweaked, tested, and monitored. The following subsections provide details from the perspective of solution design:

Early stage of proof of concept (PoC)

  • Setup and structure code bases that support an interactive ML experimentation process, as well as quick initial deployments
  • Develop and maintain toolsets and processes for ensuring the reproducibility of results
  • Code reviews with other technical team members at various stages of the PoC
  • Develop, extend, adopt a reliable, colab-like environment for ML

Late PoC

This is early to mid-stage of AI product development

  • Develop ETL pipelines. These can also be shared and/or owned by data engineers
  • Setup and maintain feature stores, databases, and data catalogs. Ensuring data veracity and lineage of on-demand pulls
  • Develop and support model health metrics

Post PoC

Responsibilities during production deployment

  • Develop and support A/B testing. Setup continuous integration and development (CI/CD) processes and pipelines for models
  • Develop and support continuous model monitoring
  • Define and publish service-level agreements (SLAs) for model serving. Such agreements include model latency, throughput, and reliability
  • L1/L2/L3 support for model debugging
  • Develop and support model serving environments
  • Model compression and distillation

We realize this list is broad and extensive. While the ideal candidate has some exposure to each of these topics, we also envision great candidates being experts at some subset. If either of those cases happens to be you, please apply.

DESIRED QUALIFICATIONS

Master’s degree or above in a STEM field. Several years of experience getting their hands dirty applying their craft.

Programming

  • Expert level Python programmer
  • Hands-on experience with Python libraries
    • Popular neural network libraries
    • Popular data science libraries (Pandas, numpy)
  • Knowledge of systems-level programming. Under the hood knowledge of C or C++
  • Experience and knowledge of various tools that fit into the model building pipeline. There are several – you should be able to speak to the pluses and minuses of a variety of tools given some challenge within the ML development pipeline
  • Database concepts; SQL
  • Experience with cloud platforms is a plus
