Hypothesis testing is the most misunderstood concept. Let's try to understand the concept with a very simple example. Hypothesis testing is nothing but, checking whether your assumption is correct or not based on your data record. An example to make you more clear picture. Suppose I say that Akash is the best student in my class.

In their decades-long chase to create artificial intelligence, computer scientists have designed and developed all kinds of complicated mechanisms and technologies to replicate vision, language, reasoning, motor skills, and other abilities associated with intelligent life. While these efforts have resulted in AI systems that can efficiently solve specific problems in limited environments, they fall short of developing the kind of general intelligence seen in humans and animals. In a new paper submitted to the peer-reviewed Artificial Intelligence journal, scientists at U.K.-based AI lab DeepMind argue that intelligence and its associated abilities will emerge not from formulating and solving complicated problems but by sticking to a simple but powerful principle: reward maximization. Titled "Reward is Enough," the paper, which is still in pre-proof as of this writing, draws inspiration from studying the evolution of natural intelligence as well as drawing lessons from recent achievements in artificial intelligence. The authors suggest that reward maximization and trial-and-error experience are enough to develop behavior that exhibits the kind of abilities associated with intelligence.

In a study published today, OpenAI, the lab best known for its research on large language models, claims it's discovered a way to improve the "behavior" of language models with respect to ethical, moral, and societal values. The approach, OpenAI says, can give developers the tools to dictate the tone and personality of a model depending on the prompt that the model's given. Despite the potential of natural language models like GPT-3, many blockers exist. The models can't always answer math problems correctly or respond to questions without paraphrasing training data, and it's well-established that they amplify the biases in data on which they were trained. That's problematic in the language domain, because a portion of the data is often sourced from communities with pervasive gender, race, and religious prejudices.

To help you fast track your company's adoption of machine learning (ML), AWS offers educational solutions for developers to get hands-on experience. We like to think of these programs as a fun way for developers to build their skills using ML technologies in real world scenarios. In this post, we walk you through how to prepare for and run an AI music competition using AWS DeepComposer. Through AWS DeepComposer, you can experience Generative AI in action and learn how to harness the latest in ML and AI. We provide an end-to-end kit that contains tools, techniques, processes, and best practices to run the event. Designed specifically to educate developers on generative AI, AWS DeepComposer includes tutorials, sample code, and training data in an immersive platform that can be used to build ML models with music as the medium of instruction. Developers, regardless of their background in ML or music, can get started with applying AI techniques including Generative Adversarial Networks (GANs), Autoregressive Convolutional Neural Networks (AR-CNN) and Transformers to generate new musical notes and accompaniments.

Building Detection identifies buildings in satellite images. The block can detect buildings of various sizes in images with ground sampling distance (GSD) of 0.55m or less. The output is provided as JSON with details of detected bounding boxes coordinates; and the image showing bounding boxes on the buildings. The block is trained on a data-set obtained from South-Eastern Asia. Note: This block needs to be used without Raster Tiling.

Last week, Facebook said it would migrate all its AI systems to PyTorch. Facebook's AI models currently perform trillions of inference operations every day for the billions of people that use its technology. Its AI tools and frameworks help fast track research work at Facebook, educational institutions and businesses globally. Big tech companies including Google (TensorFlow) and Microsoft (ML.NET), have been betting big on open-source machine learning (ML) and artificial intelligence (AI) frameworks and libraries. Predominantly, Facebook has been using two distinct but synergistic frameworks for deep learning: PyTorch and Caffe2.

Marketing and advertising are some of the functional areas where AI is expected to drive the most ROI for enterprises. Unfortunately, the industry is moving so fast that it's challenging for both marketers and technologists to keep up with all the research advances, much less apply them to pressing business problems. If these accessible AI research analyses & summaries are useful for you, you can subscribe to receive our regular industry updates below. If you'd like to skip around, here are the papers we featured: This paper describes a practical system for Multi-Touch Attribution (MTA) for use by a publisher of digital ads. We developed this system for JD.com, an eCommerce company, which is also a publisher of digital ads in China. The approach has two steps. The first step ('response modeling') fits a user-level model for purchase of a product as a function of the user's exposure to ads. The second ('credit allocation') uses the fitted model to allocate the incremental part of the observed purchase due to advertising, to the ads the user is exposed to over the previous T days. To implement step one, we train a Recurrent Neural Network (RNN) on user-level conversion and exposure data. The RNN has the advantage of flexibly handling the sequential dependence in the data in a semi-parametric way.

In this 2 hour-long project-based course, you will learn to implement neural style transfer using PyTorch. Neural Style Transfer is an optimization technique used to take a content and a style image and blend them together so the output image looks like the content image but painted in the style of the style image. We will create artistic style image using content and given style image. We will compute the content and style loss function. We will minimize this loss function using optimization techniques to get an artistic style image that retains content features and style features.

Many guides give you advice on how to get started in data science: which online courses to take, which projects to implement for your portfolio, and which skills to acquire. But what if you got started with your learning journey, and now you are somewhere in the middle and don't know where to go next? After finishing my Data Scientist nanodegree at Udacity, I was at that middle point. I had built a foundation in various data science topics -- ML, deep neural networks, NLP, recommendation systems, and more -- and my learning curve had been very steep. So I felt that simply taking another online course wouldn't yield as many "things learned per day."
