      A year has passed since "The Black Rebellion" and the remaining Black
      Knights have vanished into the shadows, their leader and figurehead, Zero,
      executed by the Britannian Empire. Area 11 is once more squirming under
      the Emperors oppressive heel as the Britannian armies concentrate their
      attacks on the European front. But for the Britannians living in Area 11,
      life is back to normal. On one such normal day, a Britannian student,
      skipping his classes in the Ashford Academy, sneaks out to gamble on his
      chess play. But unknown to this young man, several forces are eying him
      from the shadows, for soon, he will experience a shocking encounter with
      his own obscured past, and the masked rebel mastermind Zero will return.

      In a land where corruption rules and a ruthless Prime Minister has turned
      the puppet Emperors armies of soldiers, assassins and secret police
      against the people, only one force dares to stand against them: Night
      Raid, an elite team of relentless killers, each equipped with an Imperial
      Arm - legendary weapons with unique and incredible powers created in the
      distant past.

      Theres a rumor about a mysterious phenomenon called "puberty syndrome."
      For example, Sakuta Azusagawa is a high school student who suddenly sees a
      bunny girl appear in front of him. The girl is actually a girl named Mai
      Sakurajima, who is Sakutas upperclassman who is also a famous actress who
      has gone on hiatus from the entertainment industry. For some reason, the
      people around Mai cannot see her bunny-girl figure. Sakuta sets out to
      solve this mystery, and as he spends time with Mai, he learns her secret
      feelings. Other heroines who have "puberty syndrome" start to appear in
      front of Sakuta.

      Dororo, a young orphan thief, meets Hyakkimaru, a powerful ronin.
      Hyakkimarus father, a greedy feudal lord, had made a pact with 12 demons,
      offering his yet-unborn sons body parts in exchange for great power. Thus,
      Hyakkimaru - who was born without arms, legs, eyes, ears, a nose or a
      mouth - was abandoned in a river as a baby. Rescued and raised by Dr.
      Honma, who equips him with artificial limbs and teaches him sword-fighting
      techniques, Hyakkimaru discovers that each time he slays a demon, a piece
      of his body is restored. Now, he roams the war-torn countryside in search
      of demons.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("Prashasst/anime-recommendation-model")
# Run inference
sentences = [
    'I want anime like onepiece.',
    'Pirates',
    'Action',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
