یکی از ابزارهای مدرنی که این روزها بدون اینکه ازش خبر داشته باشیم ازش استفاده می‌کنیم vectorDB هست.
این ابزار دوکار مهم رو برای ما انجام می‌ده یکی ذخیره‌سازی داده‌ها به صورت بردار ویکی بازیابی شبیه‌ترین بردارها به یک بردار جدید.

به صورت ساده در این فرایند هر آبجکت(مثلا متن) به یک بردار تبدیل میشه و در دیتابیس به صورت برداری ذخیره میشه

زمانی که یک متن یا جمله جدید برای جستجو به دیتابیس داده میشه مجددا تبدیل به بردار میشه و در نهایت با بردارها(از نظر زاویه یا هر مکانیزم دیگه) مقایسه میشه و درنهایت نزدیک‌ترین بردار(ها) به عنوان خروجی برگردونده میشه.
فرضا اگر در دیتابیس کلمات زیر رو داشته باشیم

- عقاب
- شیر
- موش
- هویج

و از دیتابیس پرنده بخوایم بهمون عقاب رو بر می‌گردونه کاری که توی دیتابیس‌های قدیمی غیر ممکن بود.
برای اینکه دقیق‌تر بدونید چه اتفاقی در زمان بردارسازی و پیدا کردن خروجی می‌فته می‌تونید ویدیو زیر رو ببنید:
این ابزار یکی از کلیدی‌ترین اجزای هوش‌های مصنوعی امروز هست:

How to Invest in Bitcoin?

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
