According to the Hacker News Hiring Trends, May 2020, TensorFlow jobs are in great demand. Here are five reasons behind TensorFlow's popularity: TensorFlow is the only framework available for running machine learning models from the cloud to the tiniest microcontroller device. Models trained with TensorFlow can be optimized for CPU and GPU.


The unreasonable effectiveness of synthetic data with Daeil Kim

#artificialintelligence

The hard part is diversifying the content. So if we just have the same character in an environment doing everything, it's not going to work, right? So how do you actually create hundreds or thousands of variations of that character model with different behavior and things like that? That's been really the core focus of how we're thinking about our technology. You're listening to Gradient Dissent, a show where we learn about making machine learning models work in the real world. Daeil Kim is the co-founder and CEO of AI.Reverie. A startup that specializes in creating high quality synthetic training data for computer vision algorithms. Before that he was a senior data scientist at the New York Times. And before that he got his PhD in computer science from Brown university, focusing on machine learning and Bayesian statistics. He's going to talk about tools that will advance machine learning progress, and he's going to talk about synthetic data. I'm super excited for this. I was looking at your LinkedIn and you have a little bit of an unusual path, right? You did a liberal arts undergrad. Can you say a little bit about... I feel like I come across people quite a lot that want to make career transitions into machine learning and related fields. What was that for you? What prompted you to do it?


Machine Learning -- K-Nearest Neighbors algorithm with Python

#artificialintelligence

'K-Nearest Neighbors (KNN) is a model that classifies data points based on the points that are most similar to it. It uses test data to make an "educated guess" on what an unclassified point should be classified as' We will be building our KNN model using python's most popular machine learning package'scikit-learn'. Scikit-learn provides data scientists with various tools for performing machine learning tasks. For our KNN model, we are going to use the'KNeighborsClassifier' algorithm which is readily available in scikit-learn package. Finally, we will evaluate our KNN model predictions using the'accuracy score' function in scikit-learn.


2021 Healthcare Cybersecurity Priorities: Experts Weigh In

#artificialintelligence

Healthcare cybersecurity is in triage mode. As systems are stretched to the limits by COVID-19 and technology becomes an essential part of everyday patient interactions, hospital and healthcare IT departments have been left to figure out how to make it all work together, safely and securely. Most notably, the connectivity of everything from thermometers to defibrillators is exponentially increasing the attack surface, presenting vulnerabilities IT professionals might not even know are on their networks. Get the whole story and DOWNLOAD the eBook now – on us!] The result has been a newfound attention from ransomware and other malicious actors circling and waiting for the right time to strike. Rather than feeling overwhelmed in the current cybersecurity environment, it's important for healthcare and hospital IT teams to look at security their networks as a constant work in progress, rather than a single project with a start and end point, according to experts Jeff Horne from Ordr and G. Anthony Reina who participated in Threatpost's November webinar on Heathcare Cybersecurity. "This is a proactive space," Reina said. "This is something where you can't just be reactive. You actually have to be going out there, searching for those sorts of things, and so even on the technologies that we have, you know, we're, we're proactive about saying that security is an evolving, you know, kind of technology, It's not something where we're going to be finished." Healthcare IT pros, and security professionals more generally, also need to get a firm handle on what lives their networks and its potential level of exposure. The fine-tuned expertise of healthcare connected machines, along with the enormous cost to upgrade hardware in many instances, leave holes on a network that simply cannot be patched. "Because, from an IT perspective, you cannot manage what you can't see, and from a security perspective, you can't control and protect what you don't know," Horne said. Threatpost's experts explained how healthcare organizations can get out of triage mode and ahead of the next attack. The webinar covers everything from bread and butter patching to a brand-new secure data model which applies federated learning to functions as critical as diagnosing a brain tumor. Alternatively, a lightly edited transcript of the event follows below. Thank you so much for joining. We have an excellent conversation planned on a critically important topic, Healthcare cybersecurity. My name is Becky Bracken, I'll be your host for today's discussion.

You'll have to answer questions and we want to make sure we're covering topics most interesting to you, OK, sure. Let's just introduce our panelists today. First we have Jeff Horne. Jeff is currently the CSO at Ordr and his priors include SpaceX.


This AI Model Can Figure Out Video Games By Its Cover

#artificialintelligence

Recently, researchers from the Western Kentucky University proposed a multi-modal deep learning framework that has the capability to classify genres of video games based on the cover and textual description. The researchers claimed that this research is the first-ever attempt on automatic genre classification using a deep learning approach. Videos games have been one of the most widespread, profitable, and prominent forms of entertainment around the globe. Also, genre and its classification systems play a significant role in the development of video games. According to the researchers, video game covers and textual descriptions are usually the very first impression to its consumers, and they often convey important information about the video games.

If I wanted to learn deep learning with Python again, I would probably start with PyTorch, an open-source library developed by Facebook's AI Research Lab that is powerful, easy to learn, and very versatile. When it comes to training material, however, PyTorch lags behind TensorFlow, Google's flagship deep learning library. There are fewer books on PyTorch than TensorFlow, and even fewer online courses. Among them is Deep Learning with PyTorch by Eli Stevens, Luca Antiga, and Thomas Viehmann, three engineers who have contributed to the project and have extensive experience developing deep learning solutions. Deep Learning with PyTorch is split across two main sections, first teaching the basics of deep learning and then delving into an advanced, real-world application of medical imaging analysis.

Deep Neural Networks Help to Explain Living Brains

#artificialintelligence

In the winter of 2011, Daniel Yamins, a postdoctoral researcher in computational neuroscience at the Massachusetts Institute of Technology, would at times toil past midnight on his machine vision project. He was painstakingly designing a system that could recognize objects in pictures, regardless of variations in size, position and other properties -- something that humans do with ease. The system was a deep neural network, a type of computational device inspired by the neurological wiring of living brains. "I remember very distinctly the time when we found a neural network that actually solved the task," he said. It was 2 a.m., a tad too early to wake up his adviser, James DiCarlo, or other colleagues, so an excited Yamins took a walk in the cold Cambridge air. "I was really pumped," he said. It would have counted as a noteworthy accomplishment in artificial intelligence alone, one of many that would make neural networks the darlings of AI technology over the next few years.

Dr Ryohei Fujimaki, founder and CEO of data science company DotData, believes that data scientists are among those that will benefit the most. Fujimaki's team at DotData is helping companies accelerate their data science process.


How Chatbots Help Business Avoid the Fear of a Black-Box AI Planet

#artificialintelligence

The rise of AI in business largely goes unquestioned, until a poor decision comes out of a black box that no one can fathom or that causes actual damage. To avoid this, businesses need to adopt AI tools that are provable and customer-friendly, with chatbots paving the way until AI can be truly trusted. In most business cases, artificial intelligence helps companies progress when it comes to their varied use cases. From understanding us humans and our convoluted languages, recovering data from forms, predicting outcomes etc., AI helps spot meaning, intent and value, and provides the power for chatbots, analytic services and other digital business tools. However, as with 5G and 4G before it, as with robots in factories, and those pesky vaccines that keep us alive, there is a narrative in the media that AI is here to destroy us, to wipe out jobs, to weaken employees and other negative outcomes.
