It only takes a minute to sign up. What are the most practically useful and successful machine learning algorithms, which are possibly easy to implement neural network is ok, unless the architecture is as complicated as Google Inception etc. I am looking for an algorithm that will work fine without putting too much time into it. Are there any algorithms you've found successful and easy to use?

This can, but does not have to fall into the category of clustering. My background is from machine learning, so any suggestions are welcome :. Or you could calculate the eigenvector of each sentences. But the Problem is, what is similarity? If you want to check the semantic meaning of the sentence you will need a wordvector dataset. With the wordvector dataset you will able to check the relationship between words.

One approach you could try is averaging word vectors generated by word embedding algorithms word2vec, glove, etc. These algorithms create a vector for each word and the cosine similarity among them represents semantic similarity among the words.

In the case of the average vectors among the sentences. A good starting point for knowing more about these methods is this paper: How Well Sentence Embeddings Capture Meaning. It discusses some sentence embedding methods. I also suggest you look into Unsupervised Learning of Sentence Embeddings using Compositional n-Gram Features the authors claim their approach beat state of the art methods. Also they provide the code and some usage instructions in this github repo.

To answer your question, implementing it yourself from zero would be quite hard as BERT is not a trivial NN, but with this solution you can just plug it in into your algo that uses sentence similarity. It uses Levenshtein Distance to calculate the differences between sequences in a simple-to-use package. Also, check out this blog post for a detailed explanation of how fuzzywuzzy does the job. This blog is also written by the fuzzywuzzy author.

This blog has the solution for short text similarity. They mainly use the BERT neural network model to find similarities between sentences. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

Have you wondered how search engines understand your queries and retrieve relevant results? How chatbots extract your intent from your questions and provide the most appropriate response? Try the textual similarity analysis web-appand let me know how it works for you in the comments below! Word embeddings enable knowledge representation where a vector represents a word. This improves the ability for neural networks to learn from a textual dataset. Before word embeddings were de facto standard for natural language processing, a common approach to deal with words was to use a one-hot vectorisation.

Each word represents a column in the vector space, and each sentence is a vector of ones and zeros. Ones denote the presence of the word in the sentence. One-hot vectorisation [taken from Text Encoding: A Review ]. As a result, this leads to a huge and sparse representation, because there are much more zeros than ones.

When there are many words in the vocabulary, this creates a large word vector. This might become a problem for machine learning algorithms. One-hot vectorisation also fails to capture the meaning of words. With word embeddings, semantically similar words have similar vectors representation. Back inYoshua Bengio et al. The focus of the paper is to learn representations for words, which allow the model to predict the next word.

This paper is crucial and led to the development to discover word embeddings. Input sequence of feature vectors for words, to a conditional probability distribution over words, to predict next word [image taken from paper ]. InRonan and Jason worked on a neural network that could learn to identify similar words. Their discovery has opened up many possibilities for natural language processing.

The table below shows a list of words and the respective ten most similar words. Left figure: Neural network architecture for given input sentence, outputs class probabilities. Right table: 5 chosen words and 10 most similar words.

InTomas Mikolov et al.This article is the second in a series that describes how to perform document semantic similarity analysis using text embeddings.

The embeddings are extracted using the tf. Hub Universal Sentence Encoder module, in a scalable processing pipeline using Dataflow and tf. The extracted embeddings are then stored in BigQuery, where cosine similarity is computed between these embeddings to retrieve the most semantically similar documents. The implementation code is in the associated GitHub repository. For details on embeddings concepts and use cases, see Overview: Extracting and serving feature embeddings for machine learning. To find related documents in a collection, you can use a variety of information retrieval techniques.

One approach is to extract keywords and match documents based on the number of terms that documents have in common. However, this approach misses documents that use similar but not identical terms. Another approach is semantic similarity analysis, which is discussed in this article. With text similarity analysis, you can get relevant documents even if you don't have good search keywords to find them. Instead, you can find articles, books, papers and customer feedback by searching using representative documents.

This articles focuses on text similarity analysis based on embeddings. However, you can also use a similar approach for other types of content, such as images, audio, and videos, as long as you can convert your target contents to embeddings.

Figure 1 shows the overall architecture of the text similarity analysis solution. For the textual data, the solution uses Reuters, which is a collection of publicly available articles. The dataset is described under The Reuters dataset later in this article. The example documents are loaded in Cloud Storage.

The processing pipeline is implemented using Apache Beam and tf. Transformand runs at scale on Dataflow. In the pipeline, documents are processed to extract each article's title, topics, and content.

The processing pipeline uses the Universal Sentence Encoder module in tf. Hub to extract text embeddings for both the title and the content of each article. These values, along with the extracted embeddings, are stored in BigQuery. Having the articles and their embeddings stored in BigQuery allows you to explore similar articles using the cosine similarity metric between embeddings of titles and of contents. The solution described in this article uses ReutersDistribution 1.

The articles in the dataset appeared on the Reuters newswire in They were assembled and indexed with categories by personnel from Reuters Ltd. The full description of the dataset can be found in the collection's readme. The key attributes of the dataset are the following:. The code for the pipeline is in the pipeline.
