Continuously Indexed Domain Adaptation

arXiv.org Machine Learning

Existing domain adaptation focuses on transferring knowledge between domains with categorical indices (e.g., between datasets A and B). However, many tasks involve continuously indexed domains. For example, in medical applications, one often needs to transfer disease analysis and prediction across patients of different ages, where age acts as a continuous domain index. Such tasks are challenging for prior domain adaptation methods since they ignore the underlying relation among domains. In this paper, we propose the first method for continuously indexed domain adaptation. Our approach combines traditional adversarial adaptation with a novel discriminator that models the encoding-conditioned domain index distribution. Our theoretical analysis demonstrates the value of leveraging the domain index to generate invariant features across a continuous range of domains. Our empirical results show that our approach outperforms the state-of-the-art domain adaption methods on both synthetic and real-world medical datasets.


Comparative Study Of Best Time-Series Models For Urgent Pandemic Management-1

#artificialintelligence

Here we have used Conv1d with TimeDistributed Layer, which is then fed to a single layer of LSTM, to predicted different sequences, as illustrated by the figure below. The CNN model is built first, where each layer in the CNN model is wrapped in a TimeDistributed layer, and then added to the LSTM model. However, the other alternative approach could be used to construct the CNN model first, then add it to the LSTM model by wrapping the entire sequence of CNN layers in a TimeDistributed layer. TimeDistributed Layer is primarily used to present several sets of data (say sequences/mages) that are chronologically ordered to detect trends/ movements, actions, directions.


If You're Hyped About GPT-3 Writing Code, You Haven't Heard of NAS

#artificialintelligence

GPT-3 made headlines in the machine learning community recently over viral videos showing human language-to-code translation. The model could be used to automate many redundant and repeated coding, for example in HTML/CSS or in the construction of a simple neural network. As many others have pointed out, GPT-3 is only a tool, and very limited by its training data. Much of the more sophisticated things developers want to do -- for instance, add some specific momentum-based animation to a site -- cannot be done by GPT-3 because it a) isn't advanced enough, b) doesn't have enough training data, and c) arguably isn't "creative". GPT-3 may become a helpful tool to help developers spend less time on retyping old commands and more time on brainstorming creative infrastructure designs and debugging complex, cross-system bugs, but it's in no way a threat to the livelihoods of programmers.


What does GPT-3 mean for the future of the legal profession? โ€“ TechCrunch

#artificialintelligence

One doesn't have to dig too deep into legal organizations to find people who are skeptical about artificial intelligence. AI is getting tremendous attention and significant venture capital, but AI tools frequently underwhelm in the trenches. Here are a few reasons why that is and why I believe GPT-3, a beta version of which was recently released by the OpenAI Foundation, might be a game changer in legal and other knowledge-focused organizations. GPT-3 is getting a lot of oxygen lately because of its size, scope and capabilities. However, it should be recognized that a significant amount of that attention is due to its association with Elon Musk.


Visa Leverages Artificial Intelligence for Smarter Stand-in Processing - Digital Transactions

#artificialintelligence

Refused transactions are frustrating enough for cardholders and merchants, but during a pandemic they could be especially nerve-wracking. Visa Inc. on Wednesday announced a new service for stand-in processing that the payments network says should yield faster and more accurate results when issuers' systems are down. The new Smarter STIP (for Stand-in Processing) technology, which will debut in October, relies on artificial intelligence and so-called deep learning to help reach go or no-go decisions during service interruptions. The new system, which builds on Visa's existing STIP service, has the potential to reduce declines by as much as 50% "in some cases," Visa says. Transaction approvals satisfy cardholders and merchants but also help preserve interchange revenue for issuers.


Using artificial intelligence in retail demand management (in real life)

#artificialintelligence

Turn on your TV or fire up a web browser and, within just a few minutes, you'll come across a commercial for a product with some element of artificial intelligence inside it that makes it special. In consumer goods, it could be a low-end smartphone or a high-end refrigerator. You'll find plenty of software in commercial settings that "leverages the power of AI" in every sphere of human commercial activity. But of course, most claims of "AI" are little more than hyperbole, comprising a few algorithms that could have been coded by an undergraduate Computing Science freshman. The reasons are obvious enough, especially considering the fact that a business is literally better-valued if it claims to be using artificial intelligence.

Council Post: Do We Need More Data Or More Science In Data Science?

#artificialintelligence

Is the success of Google that of the algorithms or that of data? Today's fascination with artificial intelligence (AI) reflects both our appetite for data and our excitement about the new opportunities in machine learning. Here, I argue that newcomers to the field of data science are blinded by the shiny object of magical algorithms -- and that they forget the critical infrastructures that are needed to create and to manage data in the first place. There are now many companies that provide AI services. An attractive offer should affirm all of the above -- the sole expertise in analyses and algorithms is generally insufficient, as it does not necessarily address the data part of the equation.


What is Deep Learning?

#artificialintelligence

Data science is revolutionizing many fields; from robotics to medicine, and everything in between. This revolution is partly due to advances in research, computing power, interests within the field, and the data science toolbox. Often, persons think of data science as extreme advances within artificial intelligence (AI); as in, eventually giving robots the ability to complete human-dominated tasks all on their own. As much as this could be an aspect of data science, it is not all there is to data science. Rather, AI is part of the data science toolbox.
