### Building a 3D-CNN in TensorFlow - Analytics Vidhya

This article was published as a part of the Data Science Blogathon. The MNIST dataset classification is considered the hello world program in the domain of computer vision. The MNIST dataset helps beginners to understand the concept and the implementation of Convolutional Neural Networks. Many think of images as just a normal matrix but in reality, this is not the case. Images possess what is known as spatial information.

### What is "Stochastic" in Stochastic Gradient Descent (SGD)

Over the past 5 months, I had been reading the book Probability Essentials by Jean Jacod and Philip Protter, and the more time I spent on it, more I started to treat every encounter with Probability with a rigorous perspective. Recently, I was reading a paper in Deep Learning and the authors were talking about Stochastic Gradient Descent (SGD), which got me thinking, why is it called "stochastic"? Where is the randomness in it? Disclaimer: I won't be trying to explain any mathematical bits in this article solely because it is a pain to add equations. I hope the reader has some familiarity with the mathematical bits of the Gradient Descent algorithm and its variants. I'll provide a brief introduction where necessary, but won't be going into much detail.

### Can Machine Learning Be the Cause of Data Breaches?

Machine learning (ML) has empowered businesses to scale up to modern business demands. From training artificial Intelligence (AI) to answering customer concerns, optimizing processes to detecting and analyzing fraud, the advent of technology in business has been exquisite. While the full impact of machine learning is yet unknown, ethical issues are becoming more prevalent. ML has already experienced some unexpected catastrophic events. Therefore, debates over ML and AI ethics and risk assessments are far from over.

### Predicting Atlantic Hurricanes Using Machine Learning

Every year, tropical hurricanes affect North and Central American wildlife and people. The ability to forecast hurricanes is essential in order to minimize the risks and vulnerabilities in North and Central America. Machine learning is a newly tool that has been applied to make predictions about different phenomena. We present an original framework utilizing Machine Learning with the purpose of developing models that give insights into the complex relationship between the land–atmosphere–ocean system and tropical hurricanes. We study the activity variations in each Atlantic hurricane category as tabulated and classified by NOAA from 1950 to 2021. By applying wavelet analysis, we find that category 2–4 hurricanes formed during the positive phase of the quasi-quinquennial oscillation. In addition, our wavelet analyses show that super Atlantic hurricanes of category 5 strength were formed only during the positive phase of the decadal oscillation. The patterns obtained for each Atlantic hurricane category, clustered historical hurricane records in high and null tropical hurricane activity seasons. Using the observational patterns obtained by wavelet analysis, we created a long-term probabilistic Bayesian Machine Learning forecast for each of the Atlantic hurricane categories. Our results imply that if all such natural activity patterns and the tendencies for Atlantic hurricanes continue and persist, the next groups of hurricanes over the Atlantic basin will begin between 2023 ± 1 and 2025 ± 1, 2023 ± 1 and 2025 ± 1, 2025 ± 1 and 2028 ± 1, 2026 ± 2 and 2031 ± 3, for hurricane strength categories 2 to 5, respectively. Our results further point out that in the case of the super hurricanes of the Atlantic of category 5, they develop in five geographic areas with hot deep waters that are rather very well defined: (I) the east coast of the United States, (II) the Northeast of Mexico, (III) the Caribbean Sea, (IV) the Central American coast, and (V) the north of the Greater Antilles.

### Deepfake attacks can easily trick facial recognition

In brief Miscreants can easily steal someone else's identity by tricking live facial recognition software using deepfakes, according to a new report. Sensity AI, a startup focused on tackling identity fraud, carried out a series of pretend attacks. Engineers scanned the image of someone from an ID card, and mapped their likeness onto another person's face. Sensity then tested whether they could breach live facial recognition systems by tricking them into believing the pretend attacker is a real user. So-called "liveness tests" try to authenticate identities in real-time, relying on images or video streams from cameras like face recognition used to unlock mobile phones, for example.

### Batch Normalization… or not?

Batch Normalization (BN or BatchNorm) is a technique used to normalize the layer inputs by re-centering and re-scaling. This is done by evaluating the mean and the standard deviation of each input channel (across the whole batch), then normalizing these inputs (check this video) and, finally, both a scaling and a shifting take place through two learnable parameters β and γ. Batch Normalization is quite effective but the real reasons behind this effectiveness remain unclear. Initially, as it was proposed by Sergey Ioffe and Christian Szegedy in their 2015 article, the purpose of BN was to mitigate the internal covariate shift (ICS), defined as "the change in the distribution of network activations due to the change in network parameters during training". In fact, a reason to scale inputs is to get stable training; unfortunately this may be true in the beginning but as the network trains and the weights move away from their initial values there is no guarantee of stability.
