From Raw to Refined: A Journey Through Data Preprocessing — Part 4: Data Encoding

Dec 21, 2023

Why data encoding is necessary Humans can understand textual information. However, this is not the case for machines and any algorithms that machines run. Machines and algorithms only understand the numbers and the mathematical operations of the numbers. Therefore, if one needs to communicate textual information with machines or if one needs to input textual information to the algorithms, then the said information should be first converted into the numerical format that could represent the information. Usually, the textual data we encounter in machine learning is discrete, such as columns with limited textual values. For example, the data could contain a column named ‘day of the week’ for which only seven values are possible. Another example could be the column ‘Seasons,’ for which only four values are possible. This kind of textual data can be encoded using ordinal or one-hot encoding methods. These methods are pretty easy to implement with the built-in classes present in the Scikit-Learn library. On the other hand, in deep learning , especially in natural language processing , we will encounter textual data that is in the format of sentences or whole paragraphs. For this kind of textual data, we use a different approach. For this kind of data, we first clean the data to make it proper for encoding. After the cleaning, we use encoding methods such as CountVectorizer, TfidfVectorizer, and HashingVectorizer from the Scikit-Learn library. Another critical method that is more sophisticated is known as word embedding. We can use the methods present in the Python libraries, such as Tensorflow and gensim to encode the data using word embedding methods. Types of Textual Data (Image by Author) Methods used to encode the textual data that is usually found in machine learning tasks Ordinal Encoding and One-hot Encoding are the two most popular techniques for dealing with this type of textual data. Of course, other methods can deal with such data, but people use them less frequently. Let’s use the ‘tips’ dataset in the Seaborn library to demonstrate these methods. Ordinal Encoding This encoding type is often used with the data that can be ranked. For example, if we take an example of days in the week, we can rank them from Sunday as 0 to Saturday as 6. Let’s see how it is done. ## Importing required libraries transformed_sex_column Again, many more rows are in the output, but I am just showing some of them to save space. Methods used to encode the textual data that is usually found in deep learning task Scikit-Learn provides some classes for very basic encoding of textual data. Some of these classes are CountVectorizer, TfidfVectorizer, and HashingVectorizer. These classes will help us encode the textual data but they are far from efficient in representing the intent or nature of textual data. The most efficient technique that is used for the encoding of textual data is called word embedding. Word embeddings are a type of word representation that allows words with similar meanings to have a similar representation. Word embeddings are techniques where individual words are represented as real-valued vectors in a predefined vector space. There are three algorithms that can be used to learn the word embedding from the text corpus. Learning the word embeddings (Image by Author) Embedding layer An embedding layer is a word embedding learned jointly with a neural network model on specific natural language processing tasks, such as language modeling or document classification. It requires that document text be cleaned and prepared such that each word is one-hot encoded. The size of vector space is specified as part of the model, such as 50, 100, or 300 dimensions. The vectors are initialized with small random numbers . The embedding layer is used on the front end of a neural network and is fit in a supervised way using the backpropagation algorithm. The one-hot encoded words are mapped to the word vectors. If a multilayer Perceptron model is used, then the word vectors are concatenated before being fed as input to the model. If a recurrent neural network is used, each word may be taken as one input in a sequence. This approach of learning an embedding layer requires a lot of training data and can be slow, but it will learn an embedding both targeted to the specific text data and the NLP task. Check out the following jupyter notebook for implementing the embedding layer into the neural network. IMDB sentiment analysis – keras TextVectorization Explore and run machine learning code with Kaggle Notebooks U+007C Using data from [Private Datasource] www.kaggle.com Word2Vec is a method for effectively learning a standalone word embedding from a text corpus. These standalone word embeddings could be used to do the math of the representation of words. For example, subtracting the ‘man-ness’ from ‘king’ and adding ‘women-ness’ will give us the meaning of the word ‘queen.’ The analogy is here is King → Queen => Man → Women Two learning models that can be used as part of the word2vec approach to learning word embedding were introduced. They are: a. continuous bag-of-words or CBOW model b. continuous skip-gram model The continuous bag of words model learns the embedding by predicting the current word based on its context (surrounding words). On the other hand, the continuous skip-gram model learns by predicting the contexts (surrounding words) given a current word. Word2Vec Training Models 3. Global Vectors for Word Representation (GloVe) This is another approach to learning the embedding of the textual data. Ways to use the embedding methods Ways to use the embedding (Image by Author) Learning the embedding In this approach, we learn the embedding for our problem using the textual data available to us. If we are to learn the accurate embedding that could represent the nature of words in our corpus from scratch, we will need a large amount of textual data, maybe even billions of words. There are two ways to learn the embedding: learning the embedding without any other networks This approach is used to learn the embedding when we need to same embedding for many tasks. Here, we will learn the embedding, save it, and then use it for as many tasks as we require. learning the embedding along with the neural networks used for our specific task This approach is used to learn embedding when we need not use the embedding for more than one task. Therefore, we will learn the embedding for our data while training the neural network. 2. Reusing the embedding Everyone cannot afford to get a large amount of data to get their embedding vector. So, the solution, in this case, is to use freely available pre-trained embedding vectors from the internet. Once we obtain these freely available embeddings, we can make use of them in the following two ways. Use the downloaded embeddings as they are Once we download the embeddings from the internet, we can use them directly to train our neural network for our task. You can check out the following Kaggle notebook to know how to do this in code.
