If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
The simplest form of RNN ("vanilla" RNN) is similar to a regular neural network, only it contains a loop that allows the model to carry forward results from previous neuron layers. The image below "unrolls" how the loop works. The network looks at a series of inputs over time, X0, X1, X2, until Xt. For example, this could be a sequence of words in a sentence. The neural network has one layer of neurons for each input (in our example, one layer for each word).
This post will go point by point to see how these mistakes can manifest in a PyTorch code sample. Andrej says we should overfit a single batch. I've wasted HOURS training on a giant dataset, just to find out it's only 50% accurate because of a minor bug. The results you'll get are a good guess for the optimal performance of your architecture when it perfectly memorizes the input. Maybe that optimal performance is zero, because an exception gets thrown mid-way through.
This past Northern Hemisphere summer, I gave several talks (some in the Southern Hemisphere) in which one of the Q&A topics was the problem of collinearity between predictor variables (also known as multicollinearity). My stock response to a question on this topic was (and is) to reply with the clarifying question, "How many rows do you have to develop the model?" If the follow-up response was in the tens of thousands, my counter-response was "Don't worry about collinearity." In contrast, if the audience member's response was a few hundred rows or less, my response was "Very!" While these two different responses may seem contradictory, they actually are not.
One of the byproducts of our digitally transformed world is the accumulation of large quantities of data. Online transactions, medical records, social media posts, emails, instant messages, and connected sensors are just a few examples of the kinds of data being captured and stored on a daily basis. Scientists and research organizations have been exploring how to leverage big data for artificially intelligent applications since the 1970s. Nonetheless, until fairly recently, the big data issues for enterprises remained how to store it cost effectively, how to retrieve it efficiently when needed, and how to protect it from unauthorized access. The growth of the cloud opened up a whole new realm of cost-effective data storage and retrieval solutions, but big data was still largely perceived by enterprises as a passive asset that did not contribute significantly to their bottom lines.

Sequence prediction is a problem that involves using historical sequence information to predict the next value or values in the sequence. The sequence may be symbols like letters in a sentence or real values like those in a time series of prices. Sequence prediction may be easiest to understand in the context of time series forecasting as the problem is already generally understood. In this post, you will discover the standard sequence prediction models that you can use to frame your own sequence prediction problems. Discover how to develop LSTMs such as stacked, bidirectional, CNN-LSTM, Encoder-Decoder seq2seq and more in my new book, with 14 step-by-step tutorials and full code.
Not long after the invention of computers in the 1940s, expectations were high. Many believed that computers would soon achieve or surpass human-level intelligence. Herbert Simon, a pioneer of artificial intelligence (AI), famously predicted in 1965 that "machines will be capable, within twenty years, of doing any work a man can do"--to achieve general AI. Of course, these predictions turned out to be wildly off the mark. In the tech world today, optimism is high again.
From personalizing customer experience to automating processes, Deep Learning applications are offering smart solutions to businesses across industries, opening up a world of opportunities for them. Deep Learning algorithms use sophisticated structures, such as Convolutional Neural Networks, belief networks, or recurrent neural networks. Effective DL frameworks also help simplify the implementation of large and complex models like Convolutional Neural Networks. In this post, we present the top Deep Learning frameworks preferred by data scientists and Deep Learning experts across the globe. We have also included the major pros and cons of each framework, enabling you to choose the right one for your upcoming project.
