r/MachineLearning - [P] Time Series Analysis - Predicting Electricity Consumption using an LSTM network
So, I compared the model with ARIMA and a few interesting findings. Firstly, there doesn't appear to be any seasonal component in the data - when decomposed with statsmodels, the series simply shows a straight line. Also, ARIMA showed a mean percentage error of 23%, whereas for LSTM it was just over 8%. The daily fluctuations in electricity consumption is quite volatile, so it looks like LSTM has an advantage over ARIMA here in that it is accounting for the inherent volatility in the series. While ARIMA would usually need to be combined with a model such as GARCH to estimate this volatility, the inherent nature of LSTM allows it to handle sequential data and in this case it looks like it's handling the volatility quite well.
4 Growing Enterprise AI Trends: Where Are We Now And Where Are We Going?
Is there more to AI than automation and data processing? And now that some of the more basic functions of AI have matured, we're going to see a sharp increase in the sophistication of AI, as it becomes more and more human. The following is a brief look at where the enterprise is when it comes to AI, and where we're about to start heading. As I noted above, there are some basic functions of AI that most companies have already adopted, and that we as users can feel confident about when it comes to functionality. Those include things like personalization (personalizing ads, email messaging, auto-texts, etc.) and recommendations (such as those you see on apps like Spotify, Netflix, or in your Amazon shopping card), and other martech, which is now widely available aaS for just about any size enterprise.
Dystopian Futures of the Past: Artificial Intelligence (AI) and its Social Impact through Film and Literature
The Metropolis (Released in 1927 in Germany) is a black and white science fiction movie. It is a silent movie available with a musical score and subtitles in English. The movie was directed by Fritz Lang. It shows a grim futuristic society in the city of Metropolis which is inhabited by two distinct classes: the industrialists live off the fat of the land, supported by the workers who live under the city and endure a bare-bones existence of backbreaking work. The story concerns a relationship between Freder (played by Gustav Frรถhlich), a young man from the industrialist class, and Maria (Brigitte Helm), an activist who preaches against the divide between the two classes.
US book publishers sue Audible over AI-powered transcription
Leading the suit are the so-called "Big Five" of US publishing: Hachette, HarperCollins, Macmillan, Penguin Random House and Simon & Schuster. At the center of the case is the Captions feature the Amazon-owned company announced last month. The feature uses machine learning to allow Audible users to transcribe an audiobook into text. Since it announced Captions, Audible has positioned the feature as a student aid. However, the company also plans to make it available to subscribers.
Release Strategies and the Social Impacts of Language Models

We developed four variants of the model, ranging in size from small (124 million parameters) to large ( 1.5 billion parameters). We chose a staged release process, releasing the smallest model in February, but withholding larger models due to concerns about the potential for misuse, such as generating fake news content, impersonating others in email, or automating abusive social media content production [ 46 ]. We released the next model size in May as part of a staged release process. We are now releasing our 774 million parameter model. While large language models' flexibility and generative capabilities raise misuse concerns, they also have a range of beneficial uses - they can assist in prose, poetry, and programming; analyze dataset biases; and more.
Singularity: how governments can halt the rise of unfriendly, unstoppable super-AI
The invention of an artificial super-intelligence has been a central theme in science fiction since at least the 19th century. From E.M. Forster's short story The Machine Stops (1909) to the recent HBO television series Westworld, writers have tended to portray this possibility as an unmitigated disaster. But this issue is no longer one of fiction. Prominent contemporary scientists and engineers are now also worried that super-AI could one day surpass human intelligence (an event known as the "singularity") and become humanity's "worst mistake". Current trends suggest we are set to enter an international arms race for such a technology.
OpenAI Just Released an Even Scarier Fake News-Writing Algorithm
OpenAI, the AI company that Elon Musk founded and then quit has just released a more powerful version of its AI text-writing software. The company still won't release their full software - that can be used to write fake news and messages en masse - due to fears it might be misused. OpenAI says its text-writing system is so advanced it can write news stories and even fiction that passes as human. A user can feed the system text - anything from a few sentences to pages of it - and the system will then continue that same text in an uncannily well-written, contextually relevant, human style. However, after releasing its original system, GPT-2, in February, the company said the full software was too dangerous to release to the public - a weaker version was made available. Now, the company has announced it has released a version of GPT-2 that is six times more powerful.
