50+ NLP Interview Questions and Answers in 2023

This sparsity will make it difficult for an algorithm to find similarities between sentences as it searches for patterns. Advertisements help us provide users like you 1000’s of technical questions & answers, algorithmic codes and programming examples. The

withdraws from the agreement. Brown, T., Mann, B., Ryder, N., Subbiah, M., Kaplan, J. D., Dhariwal, P., et al. (2020).

By nature of their complexity and training, ML models tend to feature implementation that is opaque to the user, making it near-impossible to determine a model’s correctness by inspection. Therefore, comprehensive testing is essential for proper software functionality. For these reasons, CircleCI provides tools like Docker executor and container runner for containerized CI/CD environments, offering a platform that supports YAML file-based IaC configuration. Modern software development has embraced continuous integration and continuous deployment (CI/CD) to solve similar difficulties with traditional technology stacks.

Word2Vec – Turning words into vectors

The last two objectives may serve as a literature survey for the readers already working in the NLP and relevant fields, and further can provide motivation to explore the fields mentioned in this paper. Naive Bayes is a probabilistic algorithm which is based on probability theory and Bayes’ Theorem to predict the tag of a text such as news or customer review. It helps to calculate the probability of each tag for the given text and return the tag with the highest probability. Bayes’ Theorem is used to predict the probability of a feature based on prior knowledge of conditions that might be related to that feature. The choice of area in NLP using Naïve Bayes Classifiers could be in usual tasks such as segmentation and translation but it is also explored in unusual areas like segmentation for infant learning and identifying documents for opinions and facts.

The earliest NLP applications were hand-coded, rules-based systems that could perform certain NLP tasks, but couldn’t easily scale to accommodate a seemingly endless stream of exceptions or the increasing volumes of text and voice data. There are already a number of research studies suggesting that AI can perform as well as or better than humans at key healthcare tasks, such as diagnosing disease. Today, algorithms are already outperforming radiologists at spotting malignant tumours, and guiding researchers in how to construct cohorts for costly clinical trials. However, for a variety of reasons, we believe that it will be many years before AI replaces humans for broad medical process domains.

Natural Language Processing Algorithms

Each of these could provide decision support to clinicians seeking to find the best diagnosis and treatment for patients. Physical robots are well known by this point, given that more than 200,000 industrial robots are installed each year around the world. They perform pre-defined tasks like lifting, repositioning, welding or assembling objects in places like factories and warehouses, and delivering supplies in hospitals. More recently, robots have become more collaborative with humans and are more easily trained by moving them through a desired task.

Vector representations of sample text excerpts in three languages created by the USE model, a multilingual transformer model, (Yang et al., 2020) and projected into two dimensions using TSNE (van der Maaten and Hinton, 2008). Text excerpts are extracted from a recent humanitarian response dataset (HUMSET, Fekih et al., 2022; see Section 5 for details). As shown, the language model correctly separates the text excerpts about various topics (Agriculture vs. Education), while the excerpts on the same topic but in different languages appear in close proximity to each other. First, we provide a short primer to NLP (Section 2), and introduce foundational principles and defining features of the humanitarian world (Section 3).

Even AI-assisted auto labeling will encounter data it doesn’t understand, like words or phrases it hasn’t seen before or nuances of natural language it can’t derive accurate context or meaning from. When automated processes encounter these issues, they raise a flag for manual review, which is where humans in the loop come in. In other words, people remain an essential part of the process, especially when human judgment is required, such as for multiple entries and classifications, contextual and situational awareness, and real-time errors, exceptions, and edge cases. There have been a number of community-driven efforts to develop datasets and models for low-resource languages which can be used a model for future efforts. The Masakhané initiative (Nekoto et al., 2020) is an excellent example of this. Masakhané aims at promoting resource and model development for African languages by involving a diverse set of contributors (from NLP professionals to speakers of low-resource languages) with an open and participatory philosophy.

• Language is not a fixed or uniform system, but rather a dynamic and evolving one.
• This can lead to confusion or incoherent text generation.Furthermore, LLMs are not capable of handling open-ended or unstructured tasks.
• More advanced NLP models can even identify specific features and functions of products in online content to understand what customers like and dislike about them.
• It takes the information of which words are used in a document irrespective of number of words and order.
• Seunghak et al. [158] designed a Memory-Augmented-Machine-Comprehension-Network (MAMCN) to handle dependencies faced in reading comprehension.
• LSTM (Long Short-Term Memory), a variant of RNN, is used in various tasks such as word prediction, and sentence topic prediction.
