Overview of Natural Language Processing (NLP)

By -

The study of the interaction between computers and human (natural) languages is known as natural language processing (NLP), and it is a subfield of computer science, artificial intelligence, and linguistics. Speech recognition systems, automatic translation tools, and virtual assistants are just a few examples of the applications that can grasp, interpret, and synthesise human language thanks to the employment of NLP technologies.

Human language is ambiguous and context-dependent, which makes it challenging for computers to effectively interpret and understand. This is one of the main issues of NLP. NLP algorithms and models use methods like statistical analysis, machine learning, and deep learning to analyse and comprehend the structure and meaning of natural language in order to get around this problem.

Language translation is one of the main uses of NLP, enabling people to communicate with one another in many languages. Text can be automatically translated from one language to another using NLP techniques, enabling nearly immediate communication across language speakers.

Speech recognition, which enables computers to translate spoken words into written text, is another significant application of NLP. Virtual assistants that can interpret spoken orders and requests, like Apple's Siri and Amazon's Alexa, utilise this technology. 

Numerous other applications, such as text classification, sentiment analysis, and summarization, also make use of NLP. NLP algorithms can be used, for instance, to create summaries of larger documents or to automatically categorise materials according to topic or sentiment.

Overall, the discipline of natural language processing is quickly developing and is enabling computers to comprehend and engage with human language in increasingly complex ways. We may anticipate seeing even more applications that benefit from this potent technology as NLP technologies advance.

Inserting and Moving elements inside Ruby Array

By -
Here's is an array with 5 elements 2.1.2 :001 > arr = ["a", "b", "c", "d", "e"] => ["a", "b", "c", "d", "e"] Lets look at few different cases Insert a new element at starting position Using unshift 2.1.2 :002 > arr.unshift("f") => ["f", "a", "b", "c", "d", "e"] Using insert 2.1.2 :005 > arr.insert(0, "f") => ["f", "a", "b", "c", "d", "e"] In the above example 0 is the position(index) Move existing element from one position to another The element in this case is "e" Using uniq to show only unique elements 2.1.2 :009 > arr.insert(0, "e").uniq => ["e", "a", "b", "c", "d"] With uniq we are only showing unique records but the element is listed

Difference between Validations, Callbacks and Observers

By -
Validations allow you to ensure that only valid data is stored in your database. Example: validates_presence_of :user_name, :password validates_numericality_of :value We can write custom validation also as def validate   errors.add(:price, “should be a positive value”) if price.nil?|| price < 0.01 end Callbacks and observers allow you to trigger logic before or after an alteration of an object’s state. Callbacks are methods that get called at certain moments of an object’s life cycle. With callbacks it’s possible to write code that will run whenever an Active Record object is created, saved, updated, deleted, validated, or loaded from the database. Callbacks are hooks into the life cycle of an Active Record object that allow you to trigger logic before or after an alteration of the object state. This can be used to make sure that associated and dependent objects are deleted when destroy is called (by overwriting before_destroy) or to massage attribu
