This paper demonstrates that a lot of time, cost, and complexities can be saved and avoided that would otherwise be used to label the text data for classification purposes. The AI world realizes the importance of labelled data and its use for various NLP applications. Here, we have labelled and categorized close to 6,000 unlabelled samples into five distinct classes. This labelled dataset was further used for multi-class text classification. Data labelling task using transformer-based sentence embeddings and applying cosine-based text similarity threshold saved close to 20-30 days of human efforts and multiple human validations with 98.4% of classes correctly labelled as per business validation. Text classification results obtained using this AI labelled data fetched accuracy score and F1 score of 90%.

5. Cyanobacteria live mostly in aquatic habitats but they can also be found on landin deserts of all places! They lie dormant for much of the year, as it is so dry, but when it rains they become active metabolically. Although rain is good for them, it is potentially harmful for us, because these desert cyanobacteria produce harmful toxins that can be kicked up in dust storms. One might guess that the concentration of these harmful toxins is highest in soil just after it rains. To test this, imagine running an experiment in which you have four treatment groups: 1.) intact/unwatered; 2.) disturbed/unwatered; 3.) intact/watered; and 4.) disturbed/wateredwhere intact means that the surface layer of desert soil is left in place and disturbed means that 0.5cm from the surface has been scraped off, and watered versus unwatered means what it sounds like. You have a sample size of 5 in each treatment group. After ten days of watering or not watering, you measure the average concentration of the toxin in each treatment group and compare the four averages. The null hypothesis is that the mean toxin concentrations are equal across the four treatment groups. You perform a Kruskal-Wallis H test, which is a null-hypothesis significance test. The critical value for this experiment at the 0.05 level is H = 7.4; at the 0.01 level it is H = 9.8. For your data, the observed H = 10.6. First, in light of these results, what decision should you make, and second, how would you write that result up in a single sentence for the Results section of a scientific paper?.
