Need help in understanding patent law for artificial intelligence? [Project]

Context : I am a business professional who recently joined an AI startup on voice.

As my first project, I am tasked with understanding patent law better to package solutions we have built as potential patents.

To do this, I am taking this approach.

  • Research as much as possible about patent law (stuck here)
  • formulate solutions basis our ml capabilities
  • file eventually for patents.

What can be patented in artificial intelligence have very vague answers and differ everywhere.

Any help you can provide as a starting point, information I could use or a better approach is appreciated.

[D] How do I check for originality of an image among others in a database, when the images have slight but distinguishable differences?

I understand that asking for an “originality checking” neural network is very vague since there are many parameters which can affect the originality of an image, but I’m curious.

I was thinking the Siamese network approach might be beneficial. What do you think?

[Discussion] How to interpret probabilities?

So I’ve worked with machine learning a lot, but never actually had to deal directly with probabilities/probability output, and what they actually mean in a real world scenario.

So, say we have 4 balanced classes [1,2,3, and 4], and we train a Keras classifier and get the probabilities for a given prediction in the test set:

GT: Class 1

Output: [0.4, 0.3, 0.1, 0.2]

Great – the classifier predicted Class 1 correctly. But how should we interpret the 0.4 probability that was attached to the class?

Does it mean that given that particular feature vector, class 1 will be the correct choice 40% of the time?

Where does the actual performance/accuracy of the classifier come in to this?

For example, say the above classifier was trained with 100k training examples, had an accuracy of ‘50%’, and produced the probabilities of [0.4, 0.3, 0.1, 0.2]. Now imagine I got more training data and trained with 500k training examples, achieved an accuracy of 60%, and still got the probabilities of [0.4, 0.3, 0.1, 0.2]. Does the more accurate classifier better represent the actual real-life probability of the events?

tl;dr: I guess what I’m actually asking is – how do we know/measure/compare the accuracy of the probabilities given from a classifier?

[Discussion] Does Global Optimizers such as BARON help training neural networks better?

[Discussion] Does Global Optimizers such as BARON help training neural networks better?

Example cost functions of neural network

I was wondering if the cost functions of neural network are non-convex, why are we still using stochastic gradient methods such as SGD or Adam?

Does Global Optimization Solvers work? I would want to try BARON.

https://en.wikipedia.org/wiki/BARON

Does anyone has experience or know any reason why global optimizers are not being used?

Maybe hardware is not good enough? But with all the google TPU and quantum computer being developed, I doubt this is the case.

[R] Image Classification at Supercomputer Scale

If you’re interested on taking your image recognition solution to the next level efficiently using GPUs/TPUs, multi-threading and distributed computing, you may need to reorganize your processing.

Watch this introductory video on how to achieve this and you may get 4X performance improvements!!!

[R] Future of Data Processing and Sharing Survey

Dear Redditors!

I am a researcher at SBA Research investigating current data processing and sharing trends with an online survey and a subsequent interview on how people currently combine policy requirements (security policies, GDPR, etc) with their need of data processing and sharing for their business. The results will be used to help to design data processing systems that take these policies into account, yet still allow to extract value from data for businesses.

Please complete the brief pre-questionnaire below to participate in the interview. If you partake in the interview you will receive a compensation in the form of a 20 EUR Amazon voucher for, at most, one hour of your time.

https://de.surveymonkey.com/r/PDGXBM5

The pre-questionnaire should only take 3-5 minutes. The subsequent interview will be one hour at most and both your responses as part of the questionnaire and the interview are completely anonymous.

Feel free to share this information with colleagues and acquaintances that you think might be interested to participate. On behalf of science I would really appreciate your input to this study!

[P] Identifying where a picture was taken

[P] Identifying where a picture was taken

I have a collection of images taken from different windows in buildings pointing out and down. I’m trying to identify the window location on pictures facing the building. So far I’ve tried to just frame this as a regression problem with 3 images as input. See example below.

Example

I want to know if this is an existing problem and if so what is the name for it. I’ve been stuck figuring out what exactly to search. The closest I’ve found is relative camera pose estimation but its not exactly what I want.
