The document proposes a novel approach for document and feature reduction in text categorization using prototypes and rough sets. It introduces a prototype-based algorithm to reduce documents while preserving classification accuracy. A rough set-based method is also presented to select a subset of relevant features. The methods are evaluated on benchmark datasets and are shown to improve both classification performance and computational efficiency compared to baseline methods.
Image Similarity Detection at Scale Using LSH and Tensorflow with Andrey GusevDatabricks
Learning over images and understanding the quality of content play an important role at Pinterest. This talk will present a Spark based system responsible for detecting near (and far) duplicate images. The system is used to improve the accuracy of recommendations and search results across a number of production surfaces at Pinterest.
At the core of the pipeline is a Spark implementation of batch LSH (locality sensitive hashing) search capable of comparing billions of items on a daily basis. This implementation replaced an older (MR/Solr/OpenCV) system, increasing throughput by 13x and decreasing runtime by 8x. A generalized Spark Batch LSH is now used outside of the image similarity context by a number of consumers. Inverted index compression using variable byte encoding, dictionary encoding, and primitives packing are some examples of what allows this implementation to scale. The second part of this talk will detail training and integration of a Tensorflow neural net with Spark, used in the candidate selection step of the system. By directly leveraging vectorization in a Spark context we can reduce the latency of the predictions and increase the throughput.
Overall, this talk will cover a scalable Spark image processing and prediction pipeline.

Vchunk join an efficient algorithm for edit similarity joinsVijay Koushik
Similarity join is most important technique to
involve many applications such as data integration, record
linkage and pattern recognition. Here we introduce new
algorithm for similarity join with edit distance constraints.
Currently extracting overlapping grams from string and consider
only string that share certain gram as candidate. Now we propose
extracting non-overlapping substring or chunk from string.

Discovering Novel Information with sentence Level clustering From Multi-docu...irjes
Specific objective to discover some novel information from a set of documents initially retrieved in response to some query. Clustering sentences level text, effective use and update is still an open research issue, especially in domain of text mining. Since most existing system uses pattern belong to a single cluster. But here we can use patterns belongs to all cluster with different degree of membership. Since sentences of those documents we would expect at least one of the clusters to be closely related to the concepts described by the query term. This paper presents a Novel Fuzzy Clustering Algorithm that operates on relational input data (i.e. data in the form of square matrix of pair wise similarities between data objects).
A Mathematical Programming Approach for Selection of Variables in Cluster Ana...IJRES Journal
Data clustering is a common technique for statistical data analysis; it is defined as a class of
statistical techniques for classifying a set of observations into completely different groups. Cluster analysis
seeks to minimize group variance and maximize between group variance. In this study we formulate a
mathematical programming model that chooses the most important variables in cluster analysis. A nonlinear
binary model is suggested to select the most important variables in clustering a set of data. The idea of the
suggested model depends on clustering data by minimizing the distance between observations within groups.
Indicator variables are used to select the most important variables in the cluster analysis.
what is the best method to sell pi coins in 2024DOT TECH
The best way to sell your pi coins safely is trading with an exchange..but since pi is not launched in any exchange, and second option is through a VERIFIED pi merchant.
Who is a pi merchant?
A pi merchant is someone who buys pi coins from miners and pioneers and resell them to Investors looking forward to hold massive amounts before mainnet launch in 2026.
I will leave the telegram contact of my personal pi merchant to trade pi coins with.
@Pi_vendor_247
Even tho Pi network is not listed on any exchange yet.
Buying/Selling or investing in pi network coins is highly possible through the help of vendors. You can buy from vendors[ buy directly from the pi network miners and resell it]. I will leave the telegram contact of my personal vendor.

how to sell pi coins at high rate quickly.DOT TECH
Where can I sell my pi coins at a high rate.
Pi is not launched yet on any exchange. But one can easily sell his or her pi coins to investors who want to hold pi till mainnet launch.
This means crypto whales want to hold pi. And you can get a good rate for selling pi to them. I will leave the telegram contact of my personal pi vendor below.
A vendor is someone who buys from a miner and resell it to a holder or crypto whale.
Here is the telegram contact of my vendor:
