Ask HN: Where is AI/ML actually adding value at your company?

And if you buy a lot of coffee table books, you need more coffee tables.

just a happy Sumologic user, saying hello and Thanks! Most of your product is great (I am ex splunk user)... The biggest complaint is that I can't cmd+click to open anything in new tabs as everything is so JS crazy front end.

overall the pattern matching stuff is pretty cool. Also, would like a see raw logs around this for when I am trying to debug event grouping errors based on the starting regex.

One of my coworkers used basic reinforcement learning to automate a task someone used to have to do manually. We have two data ingestion pipelines. One that we ingest immediately, and a second for our larger customers which is throttled during the day and ingested at night. For the throttled pipeline, we initially had hard coded rate limits, but as we made changes to our infrastructure, the throttle was processing a different amount than it should have been. Sometimes it would process too much, and we would start to see latency build up in our normal pipeline, and other times it processed too little. For a short period of time, we had the hard coded throttle with a Slack command to override the default. This allowed an enginneer to change the rate limit if they saw we were ingesting to little or too much. While this worked, it was common that an engineer wasn't paying attention, and we would process the wrong amount for a period of time. One of my coworkers used extremely basic reinforcement learning to make the throttle dynamic. It looks at the latency of the normal ingestion pipeline, and based on that, decides how high to set the rate limit on the throttled pipeline. Thanks to him, the throttle will automatically process as much as it can, and no one needs to watch it.

The same coworker also used decision trees to analyze query performance. He trained a decision tree on the words contained in the raw SQL query and the query plan. Anyone could then read the decision tree to understand what properties of a query made that query slow. There's been times we're we've noticed some queries having odd behavior going on, such as some queries having unusually high planning time. When something like this happens, we are able to train a decision tree based on the odd behavior we've noticed. We can then read the decision tree to see what queries have the weird behavior.

I run a deep learning company focused on a lot of banking and telco fraud workloads like [1]. We have also done dl to predict failing services to auto migrate workloads before server failure.

The bulk of what we do is anomaly detection.

Here at Matterport, our research team is using deep learning to understand the 3D spaces scanned by our customers. Deep learning is great for a company like ours, where so much of our data is visual in nature and extracting that information in a high-throughput way would have been impossible before the advent of deep learning.

One way we're applying this is automatic creation of panoramic tours. Real estate is a big market for us, and a key differentiator of our product is the ability to create a tour of a home that will play automatically as either a slideshow or a 3D fly-through. The problem is, creating these tours manually takes time, as it requires navigating a 3D model to find the best views of each room. We know these tours add significant value when selling a home, but many of our customers don't have the time to create them. In our research lab we're using deep learning to create tours automatically by identifying different rooms of the house and what views of them tend to be appealing. We are drawing from a training set of roughly a million user-generated views from manually created guided tours, a decent portion of which are labelled with room type.

It's less far along, but we're also looking at semantic segmentation for 3D geometry estimation, deep learning for improved depth data quality, and other applications of deep learning to 3D data. Our customers have scanned about 370,000 buildings, which works out to around 300 million RGBD images of real places.
