2023的random小總結

突然訓唔著，想寫下。好似過去個幾年嘅summary都係：

身心俱疲
迎難而上
聽天由命

而我今年嘅總結，我只係諗到2個字，就係“重生”。今年主要可以分為8月前後（放假前後），同埋開始食Fycompa前後。1月到7月嘅自己真係好糟糕messed up，無論係身體上定係精神上。都唔係好知自己搞乜，依家回望返都覺得好可怕。（都好驚下年又會打回原形。。）。

Fycompa新藥之後仲搞笑，我成個人真係開心咗（好似話因為係由k仔 effect lol，日日都好high）。好似驅鬼咁，個個死氣沈沈、好燥底嘅自己，突然pak一聲就唔見咗了！

我對於2024年其實都係好anxious（但都多謝新藥，我比想像中冇咁anxious）。

  1. 我要提醒自己Go to Your Workplace, Do your job. Get paid. Go home。唔好擺額嘅情緒或者情感係工作上、或者同事關係上，not worthwhile at all。just forget it and move on。忘記背後，向前走。（記住自己daily salary有幾多。）
  2. 大大方方自己。Life begins when fear ends 唔好咁畏首畏尾。xhs嘅性格（瀟灑、狼性、唔需要比面）都好apply返係工作上。Take “NO” as your default answer. 
  3. 萬事只求半稱心，the secret to happiness is to lower your expectation。如果真係事情未如意，唔好掉自己去失落嘅深淵。將自己嘅expectations降低，會好過d。
  4. 工作表現上，希望可以上返4/5。如果xhs做到咁認真，好似梁朝偉一樣，希望工作都可以交返呢個質素。

本來我以為5個月嘅break後我會有d咩“大覺悟”，其實都冇。就係以上 哈哈哈。我估最大嘅struggle係到底我辭唔辭職。暫時都係先留係度啦。以上4點我要print出來做wallpaper先得lol。

我想封笔了

突然失去咗個意義。難怪好多好好嘅博主都慢慢斷更/唔update得咁密。

1）你見到好多垃圾博主不停重複垃圾內容，依然好受歡迎。繼續矇騙大眾。

2）你不停被品牌嘅PR改到七彩，而你只係一個收咗錢嘅乙方。。而中間對接人根本唔care…只係一d好low level嘅workers

3）平台越來越蝦博主，手法層出不窮。我都累了，到底要玩到幾時呀？

所以，除非係真係好top嘅brands，我都唔想再寫了。而我都run out of ideas了…知識博主係好難做到咁頻密。

下一篇做埋2024年 predictions我就收山了。

我對主業失去興趣、對副業都冇興趣、對生活本身都冇乜興趣。日復一日而已～ark邊個呢？

Generative AI Summary

How generative AI works

  • Can and cannot do
  • Common use cases: writing, reading, chatting

Generative AI Projects

  • Lifecycle of the project
  • Technology options: Prompting, RAG, Fine-tuning

Implications on Business and Society

  • Potential for automation and augmentation
  • Responsible AI, concerns

注意：加快2x没问题🉑️（andrew ng的语速挺慢）

Generative AI For Everyone (non-tech, 手把手零基础小白ok, free if audit) 要求：零基础ok，入门级non-tech内容

  • Text image audio video generation for own work+business
  • E.g. ChatGPT, Google Bard, Microsoft Bing, Midjourney
  • AI world – supervised learning (labelling things), unsupervised learning, reinforcement learning
  • Repeatedly predict the next word

Generative LLM Applications as thought partner

  • Write – brainstorm, write press release, translate
  • Read – proofread, summarize an article, summarize call center conversations, reputation monitoring, sentiment analysis
  • Chat – specialized chatbot,

What can they do and cannot do?

  • Can a fresh college graduate to complete it with correct instructions?
  • Knowledge cutoffs
  • Making things up – hallucinations
  • Text count limit
  • Not really good with tables data
  • Bias in society

Tips for prompting

  • Be detailed and specific, provide context
  • Guide the model to think through the answer
  • Experiment and iterate
  • Don’t overthink the initial prompt

Generative AI Project (E.g. Food Ordering Chatbot)

  • Repeatedly find and fix mistakes to improve performance, lifecycle:
    • Scope project
    • Build/improve system
    • Internal evaluation
    • Deploy and monitor

Cheap Option 1 – Retrieval Augmented Generation (RAG) – Reasoning Engine, NOT source of information

  • Retrieve relevant text (e.g. upload PDF, based on website articles) from documents to answer questions

Cheap Option 2 – Fine-tuning

  • Provide datasets (e.g. in certain style or structure, speaking style)
  • Gain specific knowledge (e.g. medical, financial)
  • To get a small model is OK (cheaper, can run on phone)

Very Expensive – Pretraining an LLM  

Part 3: Business & Society

  • Writing assistant
  • Marketer brainstorm
  • Recruiter summarizing comments
  • Programmer initial Python draft

Replace jobs?  Automation or Augmentation (human to double check)

  • Doesn’t replace jobs, but automate/speed up tasks
  • Technical feasibility and business value (costly! Can save money?)
  • Not just the most iconic role, can help save time and cost in some tasks

Common roles

  • Software engineer
  • ML
  • Product Manager
  • Prompt engineer?
  • Impact on knowledge workers

Concerns about AI

  • Concern 1: Humanity worst biased impulses
  • Reinforcement learning from human feedback (RLHF)
    • Human can score the generated answer to reduce bias
  • Concern 2: Job Less
  • Concern 3: Harm – self-driving cars, stock crash, unjust cass in court

Artificial General Intelligence (AGI)

  • Can do anything that a human can

Responsible AI

Fycompa 18日

本来我都唔信新藥會帶嚟personality/behaviorial change，但原來真係會lol

最近嘅我異常喜悅、好純、唔燥底、d怒火細咗好多，對人loving、grateful同體諒咗好多。身邊嘅人都好似好受了，話我overall開心咗，多野講咗。。

orz呢d 係咪euphoric mood嘅感覺？姐係食k仔個種high 咗！！（呢個係真係寫咗出嚟嘅side effect）

omg，我係全日都high咗。。係好開心呀，但好累 =_=
