Adjacent buildings with flat, gray roofs are visible. Roads with marked lanes run alongside the buildings. A red-roofed structure stands near the sports field. Vegetation includes small, scattered trees with green foliage. Cars are parked along the roads. Shadows cast by the buildings indicate different heights. Pedestrian pathways are present alongside the roads. The image contains a mix of recreational and residential zones. The layout suggests a planned urban environment."
text2 = "The picture shows a wetland full of diverse plants. The area has a network of waterways and thick vegetation, mainly tall reeds and cattails with slender, bamboo-like stalks. The scene is mostly green, with touches of blue and brown, creating a peaceful vibe. The land is mostly flat, allowing a wide view of the wetland. The image is taken from high above, giving a bird's-eye view of the waterways and aquatic plants in the wetland ecosystem."

The scene shows a heterogeneous mix of houses with varying shapes and sizes, spread across the area. The houses are painted in different colors, with some having white walls and red-tiled roofs, while others have blue or green exteriors. The residential area also contains several green spaces, including small front yards, larger parks, and gardens with various types of trees and shrubs. A broad road runs through the center of the residential area, connecting different parts of the community. The road is lined with trees on both sides and has a designated sidewalk for pedestrians. The image also captures various other elements of the urban landscape, including utility poles, streetlights, and a few commercial buildings on the outskirts of the residential area."
text4 = "The image depicts a nature reserve on an island, with a landscape dominated by sparse shrubs and meadows in the interior. The color of the image is predominantly green, with hints of brown and yellow, representing the different types of vegetation and soil.

The landscape is dotted with trees, which are scattered randomly and have a relatively low density."

The houses are single-story structures with rectangular shapes and are evenly distributed across the scene. They have a pale blue color with a hint of white, which suggests that they are constructed using plastered walls. The waste land is covered in a mixture of brown and green colors, with patches of dry grass and scattered shrubs. The trees around the houses are slender and tall, with a lush green canopy that provides shade to the area. The scene is captured from a high altitude, offering a bird's-eye view of the area. The houses and trees are clearly distinguishable, and the waste land appears as a large, empty space in the center of the image."
text7 = "The neighborhood in the picture has streets arranged in a grid pattern with consistent, low-rise buildings.

The neighborhood includes several green spaces, such as small front yards, larger parks, and gardens with different types of trees and shrubs.

The image also shows other urban features like utility poles, streetlights, and a few commercial buildings on the edges of the residential area."
text9 = "The image shows a barren and desolate landscape with little to no vegetation, dominated by a uniform color palette. The primary color is white, with some patches of gray and black. The terrain is mostly flat, with minimal changes in elevation. A white road is the only noticeable feature in the scene."

The street is flanked by tall, sleek buildings featuring a mix of modern and traditional architecture, mostly in white and beige, with some more colorful facades. The street is busy with cars in white, black, silver, and gold, and pedestrians of diverse ethnicities wearing both modern and traditional clothing. Tall, lush trees with various shades of green line the street. The sky is bright blue with a few fluffy clouds. The image is high quality, with clear, visible details."
text12 = "The image displays a residential area with houses arranged in a grid-like pattern, each having a small yard. The houses are mostly uniform in size and shape, featuring pitched roofs and rectangular windows. They come in a variety of colors, from bright ones like yellow and pink to more neutral tones like white and gray. Trees of different sizes and shapes are scattered throughout the area.

# ## Quantized Retrieval - Binary Search with Scalar (int8) Rescoring
# This demo showcases retrieval using [quantized embeddings](https://huggingface.co/blog/embedding-quantization) on a CPU. The corpus consists of 41 million texts from Wikipedia articles.
#
# <details><summary>Click to learn about the retrieval process</summary>
#
# Details:
# 1. The query is embedded using the [`mixedbread-ai/mxbai-embed-large-v1`](https://huggingface.co/mixedbread-ai/mxbai-embed-large-v1) SentenceTransformer model.
# 2. The query is quantized to binary using the `quantize_embeddings` function from the SentenceTransformers library.
# 3. A binary index (41M binary embeddings; 5.2GB of memory/disk space) is searched using the quantized query for the top 40 documents.
# 4. The top 40 documents are loaded on the fly from an int8 index on disk (41M int8 embeddings; 0 bytes of memory, 47.5GB of disk space).
# 5. The top 40 documents are rescored using the float32 query and the int8 embeddings to get the top 10 documents.
# 6. The top 10 documents are sorted by score and displayed.
#
# This process is designed to be memory efficient and fast, with the binary index being small enough to fit in memory and the int8 index being loaded as a view to save memory.
# In total, this process requires keeping 1) the model in memory, 2) the binary index in memory, and 3) the int8 index on disk. With a dimensionality of 1024,
# we need `1024 / 8 * num_docs` bytes for the binary index and `1024 * num_docs` bytes for the int8 index.
#
# This is notably cheaper than doing the same process with float32 embeddings, which would require `4 * 1024 * num_docs` bytes of memory/disk space for the float32 index, i.e. 32x as much memory and 4x as much disk space.
# Additionally, the binary index is much faster (up to 32x) to search than the float32 index, while the rescoring is also extremely efficient. In conclusion, this process allows for fast, scalable, cheap, and memory-efficient retrieval.
#
# Feel free to check out the [code for this demo](https://huggingface.co/spaces/sentence-transformers/quantized-retrieval/blob/main/app.py) to learn more about how to apply this in practice.
#
# Notes:
# - The approximate search index (a binary Inverted File Index (IVF)) is in beta and has not been trained with a lot of data. A better IVF index will be released soon.
