Multi-omics-based pan-cancer prognosis prediction using an ensemble of deep-learning and machine-learning models
The prognosis prediction of cancer patients is important for disease management. We introduce DeepProg, a new computational framework that robustly predicts patient survival subtypes based on multiple types of omic data, using an ensemble of deep-learning and machine-learning models. We apply DeepProg on 32 cancer datasets from TCGA and identified multiple cancer survival subtypes. Patient survival risk-stratification based on DeepProg is significantly better (p-value 7.9e-7 log-rank test) than Similarity Network Fusion based multi-omics data integration in all cancer types. Further comprehensive pan-cancer comparative analysis unveils the genomic signatures common among all the poorest survival subtypes, with genes enriched in extracellular matrix modeling, immune deregulation, and mitosis processes.
Google Claims Web Search to be made 10% Better by AI -- AI Daily - Artificial Intelligence News
Google has updated its search algorithms to tap into an AI language model that's better at understanding netizens' inquiries than previous frameworks. Pandu Nayak, a Google fellow and vice president of search, announced that Google has rolled out BERT, short for Bidirectional Encoder Representations from Transformers, for its most fundamental product: Google Search. It is Google's neural network-based technique for natural language processing (NLP) pre-training. Google said BERT helps better understand the nuances and context of words in searches and better match those queries with more relevant results. To do this, analysts at Google AI built a neural network known as a transformer.
Fundamentals of Deep Learning -Neural Networks
Deep Learning, many of us using this tool to solve the most complicated problems even without understanding it. Tensorflow framework and Keras Interface makes life easy for everyone. But it is necessary to know the basic concepts of Neural Networks to make your solutions more precise. Let me share my understandings. Imagine that we have a problem, the bank gave all of the transaction details such as customer name, age, bank balance, retired or not, transactions and so on.
Tesla acquires AI startup DeepScale to help build self-driving robotaxis - Electrek
Tesla has acquired a small artificial intelligence startup called DeepScale in order to help build its self-driving technology and reach its goal of building a giant fleet of robotaxis. CNBC is reporting that Tesla has acquired DeepScale, a Bay Area-based startup that focuses on "Deep Neural Network (DNN)". DeepScale CEO Forrest Iandola confirmed on LinkedIn that he joined Tesla as a "senior staff machine learning scientist": "I joined the Tesla #Autopilot team this week. I am looking forward to working with some of the brightest minds in #deeplearning and #autonomousdriving." Furthermore, the publication says that two additional sources confirmed that DeepScale was acquired by Tesla and its small team will be joining the automaker.
What is neuromorphic computing?
This article is part of Demystifying AI, a series of posts that (try to) disambiguate the jargon and myths surrounding AI. In July, a group of artificial intelligence researchers showcased a self-driving bicycle that could navigate around obstacles, follow a person, and respond to voice commands. While the self-driving bike itself was of little use, the AI technology behind it was remarkable. Powering the bicycle was a neuromorphic chip, a special kind of AI computer. Neuromorphic computing is not new.
What Is Deep Learning?
Deep learning is one of the most influential and fastest growing fields in artificial intelligence. However, getting an intuitive understanding of deep learning can be difficult because the term deep learning covers a variety of different algorithms and techniques. Deep learning is also a subdiscipline of machine learning in general, so it's important to understand what machine learning is in order to understand deep learning. Deep learning is an extension of some of the concepts originating from machine learning, so for that reason, let's take a minute to explain what machine learning is. Put simply, machine learning is a method of enabling computers to carry out specific tasks without explicitly coding every line of the algorithms used to accomplish those tasks.
