This post is a part of my forthcoming book on Mathematical foundations of Data Science.
In the previous blog, we saw how you could use basic high school maths to learn about the workings of data science and artificial intelligence
In this post we extend that idea to learn about Gradient descent

A key strength of NLP (natural language processing) is being able to process large amounts of texts and then summarise them to extract meaningful insights.
In this example, a selection of economic bulletins in PDF format from 2018 to 2019 are analysed in order to gauge economic sentiment. The bulletins in question are sourced from the European Central Bank website. tf-idf is used to rank…Continue

Evaluating a model is just as important as creating the model in the first place. Even if you use the most statistically sound tools to create your model, the end result may not be what you expected. Which metric you use to test your model depends on the type of data you’re working with and your comfort level with statistics.
Model evaluation techniques answer three main questions:

Enabling cost-effective terabyte main memory along with third-party observations of a “profound” change in storage, Intel® Optane™ DC persistent memory modules change the way we think about memory capacity, tiered memory, out-of-core algorithms, storage speed, and essentially what we can do on a computational “fat node” and with persistent storage.
With a growing ecosystem of more than 50 OEMs, ISVs and cloud service providers are exploring what is possible given the touted three-fold…Continue

I highly recommend the #StateofAI 2019 report. I have followed this report from By Nathan Benaich and Ian Hogarth
The report is free and you can download it at stateofai 2019
The report is kind of Mary Meeker theme for AI for me i.e. a great reference…Continue
Summary: More data means better models but we may be crossing over a line into what the public can tolerate, both in the types of data collected and our use of it. The public seems divided. Targeted advertising is good but the increased invasion of privacy is bad.
Headlines are full of alarm. The public is up in arms. The internet is stealing their privacy. Indeed, the Future of Humanity Institute at Oxford rates this as the most…Continue

Nobody is an island. Even less so a data scientist. Assembling predictive analytics workflows benefits from help and reviews: on processes and algorithms by data science colleagues; on IT infrastructure to deploy, manage and monitor the AI-based solutions by IT professionals; on dashboards and reporting features to communicate the final results by data visualization experts; as well as on automatization features for workflow execution by system administrators. It really seems that a…Continue

Artificial Intelligence and Machine Learning are accelerating and refining various industries. One of the most rapidly developing and progressive domains is Facial Recognition (FR). Its implementation in many spheres, from public security to retail and healthcare, only proves its potential.Continue
In my previous post, I discussed the relationship between role conflict and performance. I suggested that all things being equal, role conflict might be the primary determinant of employee performance. Companies direct all sorts of resources gathering data for recruitment purposes. All things being about the same, much of that data collection is irrelevant. …Continue

Co-Integration in Time Series Analysis is when one data points is depended on other data points or follow the pattern. Example in capital markets Industry or sector leader company stock leads the direction and many small companies follows it. Example : Crude oil and Gasoline prices. Price of gasoline is dependent on Crude oil prices. Here Crude oil price always drives gasoline prices.
To analyze similar co-integration used Moody's corporate AAA and BBB Bond Yields. Corporate…Continue

I love watching the NBA’s Golden State Warriors play basketball. Their offensive “improvisation” is a thing of beauty in their constant ball movement in order to find the “best” shot. They are a well-oiled machine optimizing split-second decisions in an ever-changing landscape that is heavily influenced by questions such as:

The use of Docker in conjunction with AWS can be highly effective when it comes to building a data pipeline.
Let me ask you if you have ever had this situation before. You are building a model in Python which you need to send over to a third-party, e.g. a client, colleague, etc. However, the person on the other end cannot run the code! Maybe they don't have the right libraries installed, or their system is not configured correctly.
Whatever the reason, Docker alleviates this…Continue
