A Practical Guide to Feature Engineering in Python
Now that we understand what feature engineering is, let's go straight into the practical aspect of this article. The first is the Loan Default Prediction dataset hosted on Zindi by Data Science Nigeria, and the second -- also hosted on Zindi -- is the Sendy Logistics dataset by Sendy. You can find the descriptions of the dataset and the corresponding machine learning tasks in the links above. If you have cloned the repo, you'll have a folder of the datasets and the notebook used for this article and can follow along easily. First, let's import some libraries and the datasets: We can see that the loan dataset has three tables.
DNNs as Layers of Cooperating Classifiers
Davel, Marelie H., Theunissen, Marthinus W., Pretorius, Arnold M., Barnard, Etienne
January 20, 2020 A BSTRACT A robust theoretical framework that can describe and predict the generalization ability of deep neural networks (DNNs) in general circumstances remains elusive. Classical attempts have produced complexity metrics that rely heavily on global measures of compactness and capacity with little investigation into the effects of sub-component collaboration. We demonstrate intriguing regularities in the activation patterns of the hidden nodes within fully-connected feedforward networks. By tracing the origin of these patterns, we show how such networks can be viewed as the combination of two information processing systems: one continuous and one discrete. We describe how these two systems arise naturally from the gradient-based optimization process, and demonstrate the classification ability of the two systems, individually and in collaboration. This perspective on DNN classification offers a novel way to think about generalization, in which different subsets of the training data are used to train distinct classifiers; those classifiers are then combined to perform the classification task, and their consistency is crucial for accurate classification. 1 Introduction One of the central tenets of computational learning theory (CL T) is that the ability of a machine-learning system to generalize to unseen data results from its compactness. That is, if the system employs a number of parameters that is small relative to the number of training samples that it processes appropriately, we can be confident that the system will generalize well to unseen samples drawn from the same distribution as the training data.

Can AI revolutionise African call centres?
The contact centre is changing. In the past, call centre agents had to process a large volume of standard calls, really quickly. But with the deployment of new technologies like artificial intelligence (AI) and robotic process automation (RPA) these agents no longer have to carry out incredibly repetitive tasks and can rather focus their attention on tackling more complex customer concerns. For call agents, RPA makes it possible to complete simple tasks across back-end systems, which reduces the amount of time spent on admin, says Adriaan van Staden, senior sales manager at call centre tech vendor Genesys South Africa. RPA is in its broadest sense an application that is governed by business logic and structured inputs, aimed at automating business processes.

The future is intelligent: Harnessing the potential of artificial intelligence in Africa
The future is intelligent: By 2030, artificial intelligence (AI) will add $15.7 trillion to the global GDP, with $6.6 trillion projected to be from increased productivity and $9.1 trillion from consumption effects. Furthermore, augmentation, which allows people and AI to work together to enhance performance, "will create $2.9 trillion of business value and 6.2 billion hours of worker productivity globally." In a world that is increasingly characterized by enhanced connectivity and where data is as pervasive as it is valuable, Africa has a unique opportunity to leverage new digital technologies to drive large-scale transformation and competitiveness. Africa cannot and should not be left behind. There are 10 key enabling technologies that will drive Africa's digital economy, including cybersecurity, cloud computing, big data analytics, blockchain, the Internet of Things, 3D printing, biotechnology, robotics, energy storage, and AI.

Predictive analysis of Bitcoin price considering social sentiments
We report on the use of sentiment analysis on news and social media to analyze and predict the price of Bitcoin. Bitcoin is the leading cryptocurrency and has the highest market capitalization among digital currencies. Predicting Bitcoin values may help understand and predict potential market movement and future growth of the technology. Unlike (mostly) repeating phenomena like weather, cryptocurrency values do not follow a repeating pattern and mere past value of Bitcoin does not reveal any secret of future Bitcoin value. Humans follow general sentiments and technical analysis to invest in the market. Hence considering people's sentiment can give a good degree of prediction. We focus on using social sentiment as a feature to predict future Bitcoin value, and in particular, consider Google News and Reddit posts. We find that social sentiment gives a good estimate of how future Bitcoin values may move. We achieve the lowest test RMSE of 434.87 using an LSTM that takes as inputs the historical price of various cryptocurrencies, the sentiment of news articles and the sentiment of Reddit posts.
Shifting from incremental improvements to sustained disruption
"The light bulb was not created by continuously improving the candle." As artificial intelligence and machine learning sweep the global economy, we find innovations from the last century becoming increasingly obsolete. In fact, the world is changing so rapidly that almost every facet of human life has been disrupted -- some more than others. Technology has revolutionized the way we communicate, undertake research, learn, interact with other people, work, travel, access healthcare, and enjoy leisurely activities. According to a report published by Tech Nation,[1] the US is the global leader in technology investments, accounting for 49% (or $149 billion) of the capital raised by tech scale-ups over the last four years (Chinese scale-ups raised 20%).
Japan, U.S., South Korea agree: no easing of North Korea sanctions without progress in nuke talks
SAN FRANCISCO – The top diplomats of Japan, the United States and South Korea on Tuesday urged North Korea to refrain from military provocation and continue denuclearization talks, but ruled out any easing of crushing economic sanctions without progress in the stalled negotiations. Foreign Minister Toshimitsu Motegi held discussions with his U.S. and South Korean counterparts, Mike Pompeo and Kang Kyung-wha, in East Palo Alto, just outside San Francisco, two weeks after a deadline set by Pyongyang for progress by the end of 2019 passed. "We agreed on the importance of North Korea making positive efforts in talks with the United States rather than going through with provocative moves," Motegi told reporters. The statement appeared to contradict remarks in a New Year speech by South Korean President Moon Jae-in a day earlier in Seoul, where he said that he could seek exemptions of U.N. sanctions to bring about improved inter-Korean relations that he believes would help restart the deadlocked nuclear negotiations between Pyongyang and Washington. Moon has previously made similar comments, despite outside worries that any lifting of sanctions could undermine U.S.-led efforts to eliminate North Korea's nuclear arsenal.
