A couple of months ago, I wrote an article about training an object detection Core ML model for iOS devices. What made this tutorial unique, though, was that I used a tool I’d built called MakeML, which allow you to start training neural networks literally in minutes. The only model type available to train in that version was a tinyYOLO based Turi Create model.

After publishing that post, many people wrote to our team letting us know that the Turi Create framework doesn’t include enough flexibility to train their models.

Imagine that you have just launched a new advertising campaign, or a new product, just like Disney’s new movie “The Lion King”, and you want to have a clear view of what people think of the movie.

Natural language processing (NLP) can help with that, and specifically the task of sentiment analysis (SA).

In simple terms, this is a technique that allows you to quickly determine if people are responding positively or negatively to a given topic—in this use case movies.

Sentiment analysis would use different techniques to tokenize and analyze every word and sentence and gather as many signals to indicate whether a review is positive, negative, or neutral.

Imagine you have to read a document that’s very dense and has numerous words you don’t know the meanings of.

What would you do?

The answer seems obvious—get out your phone, open a search engine or online dictionary, and search for the word’s meaning.

Instead of typing, what if you could instead find out all you needed to know about a word, displayed on your smartphone, just by pointing at the word on the document?

Joseph Redmon released a series of 20 lectures on computer vision in September (2018). As he is an expert in the field, I wrote a lot of notes while going through his lectures.

4I am tidying my notes for my own future reference but will post them on Medium also in case these are useful for others.

His first lecture is an introduction in which he details the differences, methods and applications of low, mid, and high level computer vision (CV).

As of this year, there are more than two billion active Android devices. The rapid adoption of Android phones has largely been due to the variety of smart apps, ranging from maps to photo editors. With the emergence of Deep Learning, our mobile apps are destined to become smarter.

The next generation of mobile apps powered by Deep Learning will learn and customize their functionality specifically for you.

Barcodes are everywhere. They provide a uniform interface for machines to identify real world items.

Thanks to the decimal code underneath the bars, barcodes are also interpretable by humans, which makes them wildly used virtually everywhere.
