Calculus For Data Science: What Do You Really Need to Know?

This one picture shows what areas of calculus and linear algebra are most useful for data scientists.

If you read any article worth its salt on the topic Math Needed for Data Science, you'll see calculus mentioned. Calculus (and it's closely related counterpart, linear algebra) has some very narrow (but very useful) applications to data science. If you have a decent algebra background (which I'm assuming you do, if you're a data scientist!) then you can learn…

Why do some traditional engineers not trust Data Science?

Introduction

I had this conversation some time ago with an Engineer who came from a traditional background.

By that I mean, he had been in the same industry (heavy engineering) for 30 years.

Of these, he had been in the same company for 25 years (and this was his second job).

 

After understanding from me about data science, he said that as an engineer, he did…

Machine Learning with TensorFlow for Absolute Beginners - Part 1

"If you want to learn something well, explain it."

Richard Feynman

What is TensorFlow?

Let's look it up on the TensorFlow.org page: "It's an end-to-end open-source machine learning platform for everyone." When TensorFlow version 2.0 came out in 2019, it was praised as a significant step towards the democratization of AI: "Now anyone can get their hands on the steering wheel!" When we sat down together to draft this article…

Introduction to Dropout to regularize Deep Neural Network

Dropout means to drop out units which are covered up and noticeable in a neural network. Dropout is a staggeringly in vogue method to overcome overfitting in neural networks.

Deep Learning framework is now getting further and more profound. With these bigger networks, we can accomplish better prediction exactness. However, this was not the case a few years ago. Deep…

P Value vs Critical Value

P-values and critical values are so similar that they are often confused. They both do the same thing: enable you to support or reject the null hypothesis in a test. But they differ in how you get to make that decision. In other words, they are two different approaches to the same result. This picture sums up the p value vs critical value approaches.…

ARIMA/SARIMA vs LSTM with Ensemble learning Insights for Time Series Data

Motivation

There are five types of traditional time series models most commonly used in epidemic time series forecasting, which includes

  • Autoregressive (AR),
  • Moving Average (MA),
  • Autoregressive Moving Average (ARMA),
  • Autoregressive Integrated Moving Average (ARIMA), and
  • Seasonal Autoregressive Integrated Moving Average (SARIMA) models.

AR models express the current value of the time series linearly in…

8 Most-Used Data Science and Machine Learning Services for 2020

In the era of the Internet, the ability to crunch large amounts of data and process it with speed and efficiency has become essential for businesses to survive. But you try sitting down and going through all that data by hand: you'll get done sometime in the year 2050 if you're lucky.

That's where machine learning comes to the rescue. But…

Why we need more Bayesian trained data scientists than frequentist post COVID 19 ..

Earlier this week, I was speaking at an event on AI for Real Estate where I showed an example from a BBC clip which said that “central London is now a ghost town” (due to COVID 19)

A few months ago, this headline would have been laughable

In London, central London and the London underground are a key fabric of daily…
