我想要一天分享一點「LLM從底層堆疊的技術」，並且每篇文章長度控制在三分鐘以內，讓大家不會壓力太大，但是又能夠每天成長一點。
以下使用 Vertex AI PaLM 2 進行情感分析，並說明決策依據：
from vertexai.language_models import TextGenerationModel
vertexai.init(project = "aiex-57523", location = "us-central1")
parameters = {"temperature": 0.2,
"max_output_tokens": 256,
"top_p": 0.8,
"top_k": 40}
model = TextGenerationModel.from_pretrained("text-bison@001")
response = model.predict("""Is the sentiment positive or negative towards Louis van Gaal based on the article and explain why in detail: Article: Louis van Gaal said he had no option but to substitute Paddy McNair in the first half against Southampton because the defender\'s \'confidence\' was shot - but believes that it will benefit the youngster in the long run. The 19-year-old was hooked by Van Gaal after only 39 minutes at St Mary\'s Stadium on Monday night during Manchester United\'s 2-1 victory over the Saints. McNair was struggling to contain Southampton strikers Shane Long and Graziano Pelle, forcing Van Gaal into replacing him prematurely. Speaking to Sky Sports after the match, Van Gaal explained: \'He (McNair) hadn\'t any confidence. He had already given three big chances away. \'I had to (substitute him), it\'s very disappointing for me and also for Paddy, but I had to because as a manager, I\'m responsible to win. \'And I think, after the change, we played a little better.\' But in spite of the fact United won the game, McNair was exposed time after time in defence and was substituted - even though Chris Smalling had already departed early with an injury. Jonny Evans came on to replace Smalling, before McNair made way for midfielder Ander Herrera as Michael Carrick dropped back in to the centre of defence in Van Gaal\'s 3-5-2 system. And, despite admitting it will be difficult for McNair to accept being replaced so early, Van Gaal insisted that it was a necessity which will serve the Northern Irishman well long term. Van Gaal continued: \'Of course, it\'s tough (for McNair), but it\'s also in his best interests.\' The victory moved United up to third in the Premier League - their highest position since they claimed the title in 2012-13 under Sir Alex Ferguson.""", **parameters)
