The dark side of Data Science

Graeme Keith

As I discuss in my article “Myths of Modelling: Data Speak”, Positivism — and, by association, its mythical beliefs — had been pretty thoroughly discredited by the 1960s. Unfortunately, as if often the case in the history of ideas, the counter-revolution over-compensated. Where the early revolutionaries would loosen the chains of narrow empiricism and open up for a more enlightened dialogue between hypotheses and the data that inspire and regulate them, the next generation would throw empiricism out all together. In the ensuing vacuity of common sense, practitioners had little choice but to crawl back to frameworks steeped in positivism.

Multidimensional multi-sensor time-series data analysis framework

Matt Mayo Editor

Multidimensional multi-sensor time-series data analysis framework. In this blog post, I will take you through my package “msda” useful for time-series sensor data analysis. A quick introduction about time-series data is also provided. The demo notebook can be found on here. One of the specific use case applications focused on “Unsupervised Feature Selection” using the package can be found in the blog post here.

Retraining Machine Learning Model approaches

Akhil Kasare
Typewriter and items

Generally machine learning models will be trained by some learning between set of input features and dependent feature or target variable. The aim of the model is to minimize the prediction error by applying or optimizing cost functions, and when we found some optimized models, we will deploy into the production and the aim is that model will generate accurate predictions on future unseen data as well so the goal is that model will predict the future unseen data as accurately as data used during the training period.

Introducing “Lux” for faster Data exploration

Saurav Anand

Most of the time spent by data scientists is in data cleaning , data exploration . A detail EDA (exploratory data analysis) is very much important and significant in the data science life cycle. In the year 2020 , there has been lot of automatic EDA libraries have been developed to save the time for the data scientist. Some of the most commonly used automatic EDA are listed in the following blog.

How AI has enhanced Sentiment Analysis using Product Review data

Alon Ghelber

Customer feedback is great. But have you been able to turn that feedback into meaningful customer insights? A few years back, brands depended on surveys to gauge customers’ feelings about how their products were performing.  From the product reviews, they were able to somehow get a grip on the general feeling of good, bad, or neutral response to their marketing campaign or product. There is, however, so much more information in the form of unstructured data that brands need to lay their hands on to better analyze the sentiments of their customers.

20 AutoML libraries for the Data Scientists

Saurav Anand

AutoML refers to automated machine learning. It explains how the end to end process of machine learning can be automated at the organizational and educational level. Initially all these steps were done manually. The demand for machine learning is increasing day by day. Let’s see some of the most common AutoML libraries which are present in different programming languages.

Why building a Machine Learning Model is like cooking

Vicky Yu

The first step in building a machine learning model is to prepare the data. This may involve pulling raw data from a variety of sources to load into a database. Likewise, the first step in cooking is to get the ingredients (the data). You may need to go to the grocery store to buy ingredients you don’t have at home (pull from a variety of sources).

Representing statistical data in plain text or paragraphs, tables are pretty boring in my opinion. What about you? They become pretty difficult to understand and contrast. But, what makes them interesting and quite beautiful is the visual representation such as charts and diagrams.
