NLP - Sentiment Classification
August 1, 2017 – December 1, 2017
1. (Model 1) Designed an interpolated n-gram model to perform sentiment classification of data from Rotton Tomato and generated random sentences. 2. (Model 2) Performed word embedding using word2vec, Glove, Tf-Idf. 3. (Model 3) Trained model with SVM, Naive Bayes and Neural Network using the embedded words obtained above and used cross-validation to test model accuracy.

Cultural Fit Analysis
The candidate has a strong background in research and development within Machine Learning and NLP, which aligns with innovative and technically driven environments. The project diversity, while focused on NLP, shows depth in a specific area. However, the target role is 'Big Data Engineer', and the resume lacks explicit experience with core big data technologies (e.g., Hadoop, Spark, Kafka, distributed systems, data warehousing, ETL pipelines). This creates a potential gap in cultural fit for a pure Big Data Engineering role, as the candidate's expertise leans heavily towards ML/NLP model development rather than large-scale data infrastructure and processing.
Soft Skills & Operational Fit
The candidate's resume highlights leadership in research and independent ownership of product life-cycles, suggesting strong initiative and problem-solving skills. The description of sharing research results indicates good communication and collaboration potential. However, without specific psychometric test results or interview data, a comprehensive assessment of soft skills and operational fit is limited.
