Resource-efficient Machine Learning in 2 KB RAM for the Internet of Things

This paper develops a novel tree-based algorithm, called Bonsai, for efficient prediction on IoT devices – such as those based on the Arduino Uno board having an 8 bit ATmega328P microcontroller operating at 16 MHz with no native floating point support, 2 KB RAM and 32 KB read-only flash. Bonsai maintains prediction accuracy while minimizing model size and prediction costs by: (a) developing a tree model which learns a single, shallow, sparse tree with powerful nodes; (b) sparsely projecting all data into a low-dimensional space in which the tree is learnt; and (c) jointly learning all tree and projection parameters. Experimental results on multiple benchmark datasets demonstrate that Bonsai can make predictions in milliseconds even on slow microcontrollers, can fit in KB of memory, has lower battery consumption than all other algorithms while achieving prediction accuracies that can be as much as 30% higher than stateof- the-art methods for resource-efficient machine learning. Bonsai is also shown to generalize to other resource constrained settings beyond IoT by generating significantly better search results as compared to Bing’s L3 ranker when the model size is restricted to 300 bytes. Bonsai’s code can be downloaded from (BonsaiCode).

Forecasting at Uber: An Introduction

This article is the first in a series dedicated to explaining how Uber leverages forecasting to build better products and services. In recent years, machine learning, deep learning, and probabilistic programming have shown great promise in generating accurate forecasts. In addition to standard statistical algorithms, Uber builds forecasting solutions using these three techniques. Below, we discuss the critical components of forecasting we use, popular methodologies, backtesting, and prediction intervals.


Low-Code Development

As organizations work to automate more knowledge-driven business processes, business and IT need to speak the same language. With complex task management passing through multiple stages and decision points, it takes a lot of effort for subject matter experts to explain processes to someone else, particularly a software developer who may or may not have domain knowledge. When requirements are misunderstood, we usually blame the developer for not listening. But in truth, it’s just as common for the business owner to have struggled to properly explain every concept. Learn more about OpenText AppWorks and low-code application development. The low-code application development platform in OpenText AppWorks gives business owners and subject matter experts a direct role in developing digital business automation. It’s an information-centered approach: Business users can think about the policy or workflow from their perspective, defining the information that needs action rather than working around a rigid process.


Deep Learning in the Trenches: Understanding Inception Network from Scratch

This article focuses on the paper ‘Going deeper with convolutions’ from which the hallmark idea of inception network came out. Inception network was once considered a state-of-the-art deep learning architecture (or model) for solving image recognition and detection problems. It put forward a breakthrough performance on the ImageNet Visual Recognition Challenge (in 2014), which is a reputed platform for benchmarking image recognition and detection algorithms. Along with this, it set off a ton of research in the creation of new deep learning architectures with innovative and impactful ideas. We will go through the main ideas and suggestions propounded in the aforementioned paper and try to grasp the techniques within. In the words of the author: ‘In this paper, we will focus on an efficient deep neural network architecture for computer vision, code named Inception, which derives its name from (…) the famous ‘we need to go deeper’ internet meme.’

We take a look at the parameters like:
• the most widely used types of AI algorithms,
• the way the companies apply the AI,
• the industries where AI implementation will have the most impact
• the most popular languages, libraries, and APIs used for AI development

Build your first chatbot using Python NLTK

A chatbot (also known as a talkbot, chatterbot, Bot, IM bot, interactive agent, or Artificial Conversational Entity) is a computer program or an artificial intelligence which conducts a conversation via auditory or textual methods. Such programs are often designed to convincingly simulate how a human would behave as a conversational partner, thereby passing the Turing test. Chatbots are typically used in dialog systems for various practical purposes including customer service or information acquisition. Some chatterbots use sophisticated natural language processing systems, but many simpler systems scan for keywords within the input, then pull a reply with the most matching keywords, or the most similar wording pattern, from a database.’
