Questions tagged [pattern-recognition]

For question about recognition of patterns (generally sequence of values following a certain mathematical equation) of any physical quantity.

Pattern recognition is concerned with the recognition of patterns and regularities in data, although it is in some cases considered to be nearly synonymous with machine learning. Pattern recognition systems are in many cases trained from labeled "training" data (supervised learning), but when no labeled data are available other algorithms can be used to discover previously unknown patterns (unsupervised learning).

What are some tactics for recognizing artificially made media?

With the growing ability to cheaply create fake pictures, fake soundbites, and fake video there becomes an increasing problem with recognizing what is real and what isn't. Even now we see a number of examples of applications that create fake media…

Using AI to extend an imagine pattern

I have created some nice patterns using the MidJourney tool. I'd like to find a way to extend these patterns, and I was thinking about an AI tool that takes one of these patterns and extends it in all directions surrounding the original…

How can I use neural networks for detecting TV channel logos in video frames?

I am trying to detect a TV channel logo inside a video file. So, simply, given an input .mp4 video, detect if it has that logo present in a specific frame, say the first frame, or not. Here's the first example of a frame with a logo. Here's the…

Which machine learning algorithm can be used to identify patterns in a dataset of the cache performance of a CPU?

I need a machine learning algorithm to identify patterns in a dataset (saved in a CSV file) that contains details of the cache performance of a CPU. More specifically, the dataset contains columns like Readhits, Readmiss or Writehits. The patterns…

Using neural network to recognise patterns in matrices

I am trying to develop a neural network which can identify design features in CAD models (i.e. slots, bosses, holes, pockets, steps). The input data I intend to use for the network is a n x n matrix (where n is the number of faces in the CAD model).…

What artificial intelligence strategies are useful for summarization?

If I have a paragraph I want to summarize, for example: Ponzo and Fila went to the mall during the day. They walked for a long while, stopping at shops. They went to many shops. At first, they didn't buy anything. After going to a number of shops,…

Is there a machine learning algorithm to find similar sales patterns?

I have a dataset as follows (and the table extends to include an extra 146 columns for companies 4-149) Is there an algorithm I could use effectively to find similar patterns in sales from the other companies when compared to my company? I thought…

How can I detect datetime patterns in text?

I want to explore and experiment the ways in which I could use a neural network to identify patterns in text. examples: Prices of XYZ stock went down at 11:00 am today Retrieve a list of items exchanged on 03/04/2018 Show error logs between 3 - 5…

Is there a way to perform pattern recognition without a labeled training set?

I have a 10GB file of a time series 1D signal. I want to find some patterns within this signal, I know CNN's are great for this but the problem is I don't have any training data. Now, I could, of course, spend an entire week slowly making 100…

Detect patterns in sequences of actions

I have to analyse sequences of actions that look more or less like this JSON blob. The question I'm trying to answer is whether there are recurring (sub)patterns that different users adopt when asked to perform a certain specific task -- in this…

What approach should I use to detect faces in video game footage?

I have set myself the challenge of detecting the locations of players/bots in videos of a well known first person shooter game (this is for a youtube series I'm planning on doing). I'm not sure which AI approach I should apply to this problem - I'm…

Is music/sound similarity comparison feasible on neural networks?

I wonder on the following concept: A given neural network gets two audio input (preferably music) and gives a real number between 0 and 1 which describes "similarity" between the second and the first track. As far as my understanding of neural…

What are some techniques/method that can be used to train and detect objects like cars and humans?

I have used OpenCV to train Haar cascades to detect face and other patterns. However I later realized that Haar tends to give a lot of false positives and I learned of Hog would give a more accurate results. But OpenCV doesn't have a good…
