The fight against deepfakes

#artificialintelligence

Last week at the Black Hat cybersecurity conference in Las Vegas, the Democratic National Committee tried to raise awareness of the dangers of AI-doctored videos by displaying a deepfaked video of DNC Chair Tom Perez. Deepfakes are videos that have been manipulated, using deep learning tools, to superimpose a person's face onto a video of someone else. As the 2020 presidential election draws near, there's increasing concern over the potential threats deepfakes pose to the democratic process. In June, the U.S. Congress House Permanent Select Committee on Intelligence held a hearing to discuss the threats of deefakes and other AI-manipulated media. But there's doubt over whether tech companies are ready to deal with deepfakes.

Machine Learning: How to Build Scalable Machine Learning Models

#artificialintelligence

Your preferred abstraction level can lie anywhere between writing C code with CUDA extensions to using a highly abstracted canned estimator, which lets you do a lot (optimize, train, evaluate) with fewer lines of code but at the cost of less control on implementation. It mostly depends on the complexity and novelty of the solution that you intend to develop.


INSIGHT: AI in Health Care--A Look at Critical Data Regulations

#artificialintelligence

Artificial intelligence tools permeate the health care landscape, even though many health care practitioners don't realize that they're leveraging such tools in their everyday practice. The American Medical Association, in a report from its 2018 Annual Meeting, described AI as: "a host of computational methods that produce systems that perform tasks normally requiring human intelligence. These computational methods include, but are not limited to, machine image recognition, natural language processing, and machine learning." The AMA emphasized in its report, however, that another term used in the health care setting with regard to AI is "augmented intelligence," given that AI generally is designed to "enhance the capabilities of human clinical decision making," particularly in the health care industry. In other words, AI is a tool that, at its best, helps humans make better decisions, and complete tasks more efficiently and effectively.

As a result, this will provide survival and game-changing strategies in this evolutionary world.


Bringing machine learning to the masses

#artificialintelligence

Artificial intelligence (AI) used to be the specialized domain of data scientists and computer programmers. But companies such as Wolfram Research, which makes Mathematica, are trying to democratize the field, so scientists without AI skills can harness the technology for recognizing patterns in big data. In some cases, they don't need to code at all. Insights are just a drag-and-drop away. One of the latest systems is software called Ludwig, first made open-source by Uber in February and updated last week.


AI is going to change journalism – here's how

#artificialintelligence

At RADAR, journalists develop templates for AI to fill in with local data. These templates include "fragments of text and logical if-then-else rules for how to translate the data into location-specific text," according to its website. Data journalists have to come up with various angles and storylines, and then do some reporting to "add broad-strokes background information and national context, which are written into a template with a basic story structure." The result is stories with a similar core structure but with local details. Using AI, one data journalist can produce around 200 regional stories for each template every week, RADAR said.


Consultant's notes: User story & requirements - My Day To-Do

#artificialintelligence

One of the things I aim to highlight in this post is how to carefully examine and understand a problem before applying cutting edge technology to solve it. In this post, we will first look at a problem from the end-user's perspective, establish and understand the user story, then propose the technology to solve it. As a busy consultant who visits lots of clients, there's a lot information that I come across which I want to note. However, I don't have the time to write (or type) them all down, typically I would make paper notes, which I end up misplacing from time to time. Additionally, in my pile of my paper notes, I often find it difficult to find the information I need.


Short Text Topic Modeling

#artificialintelligence

The most popular Topic Modeling algorithm is LDA, Latent Dirichlet Allocation. Let's first unravel this imposing name to have an intuition of what it does. Figure 1 below describes how the LDA steps articulate to find the topics within a corpus of documents. "A document is generated by sampling a mixture of these topics and then sampling words from that mixture" (Andrew Ng, David Blei and Michael Jordan from the LDA original paper). NB: In the Figure 1 above, we have set K 3 topics and N 8 words in our vocabulary for illustration ease.
