Nvidia「宇宙」平台:模擬多重宇宙訓練未來機械人

人工智能的「多元宇宙模擬引擎」預測未來以訓練人形機器人和自駕車

研究人員建造了一個新的「多元宇宙模擬」平台,能夠生成大量數據以訓練由人工智能(AI)驅動的先進自學機器人。這個名為「Cosmos」的工具套件,讓研究人員創建「世界基礎模型」——神經網絡模擬現實環境和物理法則,從而預測現實結果。根據開發這個平台的Nvidia公司所述,這些生成式AI模型能夠產生合成數據,以訓練具體或實體的AI系統,比如自動駕駛車輛(AV)或人形機器人。

訓練AI系統需要大量數據,但科學家估計到2026年時,我們可能會耗盡公共可用數據。與現實世界互動的AI系統,如機器人,通常需要獲取極難生產且成本高昂的真實世界影像。

然而,創建真正有用的合成數據也是一個挑戰,之前有研究警告說,使用構建不當的合成數據可能會變得無法理解。Cosmos旨在解決這些問題,讓科學家能夠快速生成大量基於現實物理的人工視頻資料。

模擬多元宇宙

這個新平台的一個關鍵組件是多元宇宙模擬,在這個過程中,Cosmos與Nvidia的Omniverse軟件系統結合,以生成特定場景中每一種可能的未來結果。這些結果將用於機器人或自駕車的訓練。

該平台使用了用於圖像生成的擴散模型——這是一種通過向數據集中添加「噪音」(顆粒狀的規格)來生成數據的機器學習算法,然後學習去除噪音,以及自回歸模型,這是一種用於預測過程中下一步的統計模型。這兩者結合後,平台能夠接收文本、圖像或視頻,並生成預測特定場景下一步的視頻資料。

Nvidia的創始人兼首席執行官黃仁勳在一份聲明中表示:「機器人的ChatGPT時刻即將到來。像大型語言模型一樣,世界基礎模型對於推進機器人和自駕車的發展至關重要,但並非所有開發者都具備訓練自己的專業知識和資源。我們創建Cosmos是為了讓物理AI變得民主化,讓每個開發者都能夠接觸到通用機器人技術。」

使用Cosmos創建的世界基礎模型也可在開源許可條款下獲得。

這項技術的出現不僅為機器人技術的發展提供了新的可能性,還可能改變整個自動駕駛和人工智能行業的生態系統。隨著AI技術的普及,未來我們可能會看到更多創新的應用場景,這些場景不僅限於工業或商業領域,還可能滲透到我們的日常生活中。隨著技術的進步,如何確保這些機器人和自駕車的安全性和可靠性,將成為未來需要重視的議題。

The gown features a sculpted corset bodice richly embroidered with gold hieroglyphic motifs, sun-disk patterns, and crystal beadwork. Flowing white silk, chiffon, and sheer organza panels cascade dramatically from the waist and shoulders, creating powerful movement as she rides. A daring thigh-high slit reveals her leg, balancing sensuality with imperial elegance. Every seam is traced with gold-thread embroidery for a luminous, goddess-like silhouette.",
"accessories": "She wears the exact Cleopatra headpiece from the attached reference image: a regal black-and-gold striped nemes-style headdress with a polished gold cobra (uraeus) centerpiece at the forehead, structured side panels, and intricate gold detailing. Paired with a wide Egyptian collar necklace with turquoise accents, engraved gold arm cuffs, crystal finger rings, an ornate gold waist belt, delicate anklets, and elegant flat Egyptian sandals.",
"hair": "Her hair is fully concealed beneath the nemes headpiece as shown in the reference image, ensuring perfect historical accuracy and symmetry.",
"makeup": "Ultra-bold, highly colorful Egyptian eye makeup with ceremonial ink artistry. Her eyes feature sharp elongated black kohl eyeliner extended dramatically past the outer corners, layered with vivid turquoise, teal, emerald green, sapphire blue, violet, and metallic gold pigments blended in high-fashion gradients. Beneath each eye, intricate hand-drawn ink designs inspired by ancient Egyptian symbolism are visible—fine black and gold lines, dots, and sacred motifs echoing hieroglyphs and protective markings, following the natural curve of the lower eye and cheekbone. Her complexion is flawless and softly bronzed with luminous highlights, brows are sculpted and powerful, cheeks carry a subtle coral-rose flush, and lips are finished in a refined nude-rose satin tone to balance the intense, artistic eye look."
