Neural Networks:  Is Meta-learning the New Black?

I’ve written several times about how the “economies of learning” are more powerful than the “economies of scale”.  Through a continuous learning and refinement process, organizations can simultaneously drive down marginal costs while accelerating time-to-value and de-risking projects via digital asset re-use and refinement (see Figure 1).…

Detecting Bias with SHAP

StackOverflow’s annual developer survey concluded earlier this year, and they have graciously published the (anonymized) 2019 results for analysis. They’re a rich view into the experience of software developers around the world — what’s their favorite editor? how many years of experience? tabs or spaces? and crucially, salary. Software engineers’ salaries are good, and sometimes both eye-watering and news-worthy.

The tech industry is also painfully aware that it does not always live…

Breaking the HDFS Performance Barrier; An Object Storage First

By Siddartha Mani

Few would argue with the statement that Hadoop HDFS is in decline. In fact, the HDFS part of the Hadoop ecosystem is in more than just decline - it is in freefall. At the time of its inception, it had a meaningful role to play as a high-throughput, fault-tolerant distributed file system. The secret sauce was data locality. 

By co-locating compute and data on the same nodes, HDFS overcame the limitations of slow network access to data. The…

Diabetes Prediction with Ensemble Techniques

Till your good is better and better is best!

ENSEMBLE

Yes, the above quote is so true. We humans have ability to rate things and find some or the other matrices to measure things and evaluate them or their performances. Similarly, in Data Science you can measure your model’s accuracy and performance! The very first model that you build, you can set its matrices from the results and these matrices become your…

Social-Organizational-Institutional Versus Market Devaluation

In Ontario, there has been a push for education to become more “monetizeable.”  The education that people receive should better reflect the needs of the market.  This is actually a challenging proposition - even if people are entirely in agreement - given the elusive nature of the market.  I am a big market proponent myself.  This has led me to question where or not my undergraduate degree has any commercial value at all.  I have a degree in environmental studies.  My thesis was on the…

Difference between Gradient Descent and Newton-Raphson

Below are some extracts from an interesting Quora discussion on this topic.

Quotes:

  • The gradient descent way: You look around your feet and no farther than a few meters from your feet. You find the direction that slopes down the most and then walk a few meters in that direction. Then you stop and repeat the process until you can repeat no more. This will eventually lead you to the valley!
  • The Newton way: You look far away.…

Machine Learning has Significant Potential for the Manufacturing Sector

Since the start of the renaissance era, technology started to take over the lives of the humans and to gown to greater heights in the coming decade with completely replacing man from few spots in terms of the manual work or heavy work, they most influenced sector was the industrial sector. Since, it’s more oriented to the manual work which has rapidly changed the face of the industrial sector.

But now when the machines already captured most of the manual workspaces from man, now they…
