📝 Editorial

Writing machine learning programs remains a relatively subjective process. Given a problem, we trust data scientists and machine learning engineers to select the best models and architectures, but how do we know those are correct? Data scientists have their own preferences and biases which can influence the machine learning models they apply to a specific problem. Emerging thinking in space is that we can use machine learning to build better machine learning models.

Writing machine learning with machine learning is not a problem with a single solution. Methods such as neural architecture search (NAS, covered in Edge#4) try to select the best model for a given problem. Meta-learning focuses on creating models that can “learn to learn” while program synthesis tackles the difficult challenge of finding the best machine learning programs for a specific dataset. Just this week, Google published research outlining TF-Coder, a new framework that can generate TensorFlow tensor transformations from features. One thing is certain: in the future, machine learning will help us write better machine learning.

🤖 Cool AI Tech Releases

Model Card Toolkit for model transparency

Google AI introduced Model Cards, which provides a structured framework for reporting on ML model provenance, usage, and ethics-informed evaluation. It gives a detailed overview of a model’s suggested uses and limitations ->read more on Google AI blog

Introducing ScaNN for more efficient search

The recently announced open-sourced vector similarity search library (ScaNN) outperforms other libraries by a factor of two. It performed better than eleven other libraries, handling roughly twice as many queries per second for a given accuracy as the next-fastest library ->read more on Google AI blog

PyTorch for Windows

💸 Money in AI

  • Accounting startup Candis raised almost $14 million in its funding round. On the platform for automated accounting and payment processes, the algorithms are used to import files, extract data, approve invoices, and handle exporting. Sounds mundane but saves a lot of time and improves accuracy.
  • Two data-driven construction reporting companies closed rounds this week. $15.9 million for OpenSpace and $16 million for Buildots. Both companies use 360-degree cameras, which are strapped to builders’ and managers’ hats to document the evolution of a site.
  • A dual commercial and nonprofit enterprise AI Foundation closed a $17 million funding round. They develop AI avatars that can replicate one’s personality, can be trained to complete tasks, or play the role of an assistant or an advisor. It can be your own replica or replica of a famous person.
  • Computer vision startup Advertima has raised ~$17.5 million Series A. Their machine learning platform and the in-store sensors help physical retail stores ‘upgrade’ the shopping experience via real-time shopper behavior analytics.
  • AI-powered vision startup Instrumental closed a $20 million Series B. It helps detect manufacturing anomalies, using a combination of cameras and code.
  • Conversation intelligence startup Chorus.ai has raised a $45 million round. With AI and its proprietary natural language processing (NLP) algorithms, Chorus.ai analyzes calls and extracts insights to help with sales.
  • A serious $51 million round was raised by another AI-powered vision startup this week. Density uses infrared sensors to count people and analyze crowd behavior, helping companies understand which parts of their offices and other spaces are used more and which are used less.
  • Home fitness startup Tempo just closed a $60 million round. Its AI-powered gym uses 3D infrared sensors that scan users’ movements 30 times per second for performance tracking and better feedback.
