How do you pull information from raw data?

Turn data into actionable insights

Measure the right things

Measure the right things. What is the problem you are trying to solve? This understanding is stated at the commencement of everything as getting clarity a clear idea about the problem to be solved, allows you to determine which data will be used to answer to core question.

Ask the right questions to stakeholders

Ask the right questions to stakeholders. This phase is utmost important as this is where the intention of the project will be outlined. Here two things matter: Communication and Clarity. But the drawbacks here is that each stakeholder will has its own objectives, biases, and modalities of related information. As results, They will not comprehend things in the same way, they will not see things  in the same manner. Without clear, concise and complete perspective of what the project goals are, we are heading to failure.

Understand your data

This phase relies on the second phase. Data is collected at this stage based on what the stakeholders want and need from what sources and by what means.

Prepare your data

Since data have been collected. The next stage is to transform them into usable subset. Make sure you check for questionable, missing and  all ambiguous cases. Don’t forget during all the life-cycle of the data you will need to validate its uniformity (to avoid anomalies), its integrity (to avoid loss of information), its unicity (to get rid of duplicated records) and finally its security ( to avoid some access)  of course as long as it depends on you.

Model your data

This is here you are going to extract all those meaningful insights hidden behind that ton of data. This is the main purpose of the game. To create knowledge and insights which have meaning and utility. To reveal patterns  and structures from the raw data. Models are selected on a subset of data and can be adjusted if needed.

Evaluate your model

At this stage, the selected model(s) will be tested to be validated. The model(s) will be tested on  a pre-selected dataset (generally known as test_set). This is after performing this test you will validate the efficacy of the model(s) on  new dataset.


The last stage is called  ” Deployment”. Now your model will be used on new data outside of the scope and by new stakeholders. Bear in mind new interactions could reveal new variables for the model(s). Don’t be upset if those interactions will initiate revision of your model. Sometimes you will need to revise the model(s) but most of the time you will revise either the business needs or the data.

How long does the corona virus last on surfaces?

So far It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other corona viruses. Studies suggest that corona viruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days.

Who is most at risk for the coronavirus disease?

Anyone can be infected by the new corona virus. It doesn’t matter how old you are, you can be infected by the new coronavirus (2019-nCoV). Of course, Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more susceptible  to becoming severely ill with the virus.

WHO advises people of all ages to fully comply with the instructions to protect themselves from the virus, for example :

  1. Wear your gloves
  2. wear your face-mask
  3. Don’t touch your eyes, nose and mouth
  4. Perform hygiene frequently
  5. Last but not least, Stay home! Stay home! Stay home !

Update on H and J Visas for Medical Professionals

Last Updated: March 26, 2020

The U.S. Department of State encourage medical professionals seeking to work in the United States on a work or exchange visitor, particularly those working to treat or mitigate the effects of COVID-19, to reach out to the nearest embassy or consulate to request a visa appointment.

For those foreign medical professionals already in the United States:

J-1 Alien Physicians (medical residents) may consult with their program sponsor, ECFMG, to extend their programs in the United States.  Generally, a J-1 program for a foreign medical resident can be extended one year at a time for up to seven years.

Note that the expiration date on a U.S. visa does not determine how long one can be in the United States.  The way to confirm one’s required departure date is here:

Those who need to extend their stay or adjust their visa status must apply with USCIS.  Their website is here:
